Attestation

-

This page explains Constellation's attestation process and highlights the cornerstones of its trust model.

-

Terms​

-

The following lists terms and concepts that help to understand the attestation concept of Constellation.

-

Trusted Platform Module (TPM)​

-

A TPM chip is a dedicated tamper-resistant crypto-processor. -It can securely store artifacts such as passwords, certificates, encryption keys, or runtime measurements (more on this below). -When a TPM is implemented in software, it's typically called a virtual TPM (vTPM).

-

Runtime measurement​

-

A runtime measurement is a cryptographic hash of the memory pages of a so called runtime component. Runtime components of interest typically include a system's bootloader or OS kernel.

-

Platform Configuration Register (PCR)​

-

A Platform Configuration Register (PCR) is a memory location in the TPM that has some unique properties. -To store a new value in a PCR, the existing value is extended with a new value as follows:

-
PCR[N] = HASHalg( PCR[N] || ArgumentOfExtend )
-

The PCRs are typically used to store runtime measurements. -The new value of a PCR is always an extension of the existing value. -Thus, storing the measurements of multiple components into the same PCR irreversibly links them together.

-

Measured boot​

-

Measured boot builds on the concept of chained runtime measurements. -Each component in the boot chain loads and measures the next component into the PCR before executing it. -By comparing the resulting PCR values against trusted reference values, the integrity of the entire boot chain and thereby the running system can be ensured.

-

Remote attestation (RA)​

-

Remote attestation is the process of verifying certain properties of an application or platform, such as integrity and confidentiality, from a remote location. -In the case of a measured boot, the goal is to obtain a signed attestation statement on the PCR values of the boot measurements. -The statement can then be verified and compared to a set of trusted reference values. -This way, the integrity of the platform can be ensured before sharing secrets with it.

-

Confidential virtual machine (CVM)​

-

Confidential computing (CC) is the protection of data in-use with hardware-based trusted execution environments (TEEs). -With CVMs, TEEs encapsulate entire virtual machines and isolate them against the hypervisor, other VMs, and direct memory access. -After loading the initial VM image into encrypted memory, the hypervisor calls for a secure processor to measure these initial memory pages. -The secure processor locks these pages and generates an attestation report on the initial page measurements. -CVM memory pages are encrypted with a key that resides inside the secure processor, which makes sure only the guest VM can access them. -The attestation report is signed by the secure processor and can be verified using remote attestation via the certificate authority of the hardware vendor. -Such an attestation statement guarantees the confidentiality and integrity of a CVM.

-

Attested TLS (aTLS)​

-

In a CC environment, attested TLS (aTLS) can be used to establish secure connections between two parties using the remote attestation features of the CC components.

-

aTLS modifies the TLS handshake by embedding an attestation statement into the TLS certificate. -Instead of relying on a certificate authority, aTLS uses this attestation statement to establish trust in the certificate.

-

The protocol can be used by clients to verify a server certificate, by a server to verify a client certificate, or for mutual verification (mutual aTLS).

-

Overview​

-

The challenge for Constellation is to lift a CVM's attestation statement to the Kubernetes software layer and make it end-to-end verifiable. -From there, Constellation needs to expand the attestation from a single CVM to the entire cluster.

-

The JoinService and VerificationService are where all runs together. -Internally, the JoinService uses remote attestation to securely join CVM nodes to the cluster. -Externally, the VerificationService provides an attestation statement for the cluster's CVMs and configuration.

-

The following explains the details of both steps.

-

Node attestation​

-

The idea is that Constellation nodes should have verifiable integrity from the CVM hardware measurement up to the Kubernetes software layer. -The solution is a verifiable boot chain and an integrity-protected runtime environment.

-

Constellation uses measured boot within CVMs, measuring each component in the boot process before executing it. -Outside of CC, this is usually implemented via TPMs. -CVM technologies differ in how they implement runtime measurements, but the general concepts are similar to those of a TPM. -For simplicity, TPM terminology like PCR is used in the following.

-

When a Constellation node image boots inside a CVM, measured boot is used for all stages and components of the boot chain. -This process goes up to the root filesystem. -The root filesystem is mounted read-only with integrity protection. -For the details on the image and boot stages see the image architecture documentation. -Any changes to the image will inevitably also change the corresponding PCR values. -To create a node attestation statement, the Constellation image obtains a CVM attestation statement from the hardware. -This includes the runtime measurements and thereby binds the measured boot results to the CVM hardware measurement.

-

In addition to the image measurements, Constellation extends a PCR during the initialization phase that irrevocably marks the node as initialized. -The measurement is created using the clusterID, tying all future attestation statements to this ID. -Thereby, an attestation statement is unique for every cluster and a node can be identified unambiguously as being initialized.

-

To verify an attestation, the hardware's signature and a statement are verified first to establish trust in the contained runtime measurements. -If successful, the measurements are verified against the trusted values of the particular Constellation release version. -Finally, the measurement of the clusterID can be compared by calculating it with the master secret.

-

Runtime measurements​

-

Constellation uses runtime measurements to implement the measured boot approach. -As stated above, the underlying hardware technology and guest firmware differ in their implementations of runtime measurements. -The following gives a detailed description of the available measurements in the different cloud environments.

-

The runtime measurements consist of two types of values:

-
    -
  • -

    Measurements produced by the cloud infrastructure and firmware of the CVM: -These are measurements of closed-source firmware and other values controlled by the cloud provider. -While not being reproducible for the user, some of them can be compared against previously observed values. -Others may change frequently and aren't suitable for verification. -The signed image measurements include measurements that are known, previously observed values.

    -
    • -
  • -

    Measurements produced by the Constellation bootloader and boot chain: -The Constellation Bootloader takes over from the CVM firmware and measures the rest of the boot chain. -The Constellation Bootstrapper is the first user mode component that runs in a Constellation image. -It extends PCR registers with the IDs of the cluster marking a node as initialized.

    -
    • -
-

Constellation allows to specify in the config which measurements should be enforced during the attestation process. -Enforcing non-reproducible measurements controlled by the cloud provider means that changes in these values require manual updates to the cluster's config. -By default, Constellation only enforces measurements that are stable values produced by the infrastructure or by Constellation directly.

-

Constellation uses the vTPM (NitroTPM) feature of the AWS Nitro System on AWS for runtime measurements.

The vTPM adheres to the TPM 2.0 specification. -The VMs are attested by obtaining signed PCR values over the VM's boot configuration from the TPM and comparing them to a known, good state (measured boot).

The following table lists all PCR values of the vTPM and the measured components. -It also lists what components of the boot chain did the measurements and if the value is reproducible and verifiable. -The latter means that the value can be generated offline and compared to the one in the vTPM.

CVM verification​

-

To verify the integrity of the received attestation statement, a chain of trust from the CVM technology to the interface providing the statement has to be established. -For verification of the CVM technology, Constellation may expose additional options in its config file.

-

On AWS, AMD SEV-SNP is used to provide runtime encryption to the VMs. -An SEV-SNP attestation report is used to establish trust in the VM. -You may customize certain parameters for verification of the attestation statement using the Constellation config file.

    -
  • -

    TCB versions

    -

    You can set the minimum version numbers of components in the SEV-SNP TCB. -Use the latest versions to enforce that only machines with the most recent firmware updates are allowed to join the cluster. -Alternatively, you can set a lower minimum version to allow slightly out-of-date machines to still be able to join the cluster.

    -
    • -
  • -

    AMD Root Key Certificate

    -

    This certificate is the root of trust for verifying the SEV-SNP certificate chain.

    -
    • -
  • -

    AMD Signing Key Certificate

    -

    This is the intermediate certificate for verifying the SEV-SNP report's signature. -If it's not specified, the CLI fetches it from the AMD key distribution server.

    -
    • -
-

Cluster attestation​

-

Cluster-facing, Constellation's JoinService verifies each node joining the cluster given the configured ground truth runtime measurements. -User-facing, the VerificationService provides an interface to verify a node using remote attestation. -By verifying the first node during the initialization and configuring the ground truth measurements that are subsequently enforced by the JoinService, the whole cluster is verified in a transitive way.

-

Cluster-facing attestation​

-

The JoinService is provided with the runtime measurements of the whitelisted Constellation image version as the ground truth. -During the initialization and the cluster bootstrapping, each node connects to the JoinService using aTLS. -During the handshake, the node transmits an attestation statement including its runtime measurements. -The JoinService verifies that statement and compares the measurements against the ground truth. -For details of the initialization process check the microservice descriptions.

-

After the initialization, every node updates its runtime measurements with the clusterID value, marking it irreversibly as initialized. -When an initialized node tries to join another cluster, its measurements inevitably mismatch the measurements of an uninitialized node and it will be declined.

-

User-facing attestation​

-

The VerificationService provides an endpoint for obtaining its hardware-based remote attestation statement, which includes the runtime measurements. -A user can verify this statement and compare the measurements against the configured ground truth and, thus, verify the identity and integrity of all Constellation components and the cluster configuration. Subsequently, the user knows that the entire cluster is in the expected state and is trustworthy.

-

Putting it all together​

-

This section puts the aforementioned concepts together and illustrate how trust into a Constellation cluster is established and maintained.

-

CLI and node images​

-

It all starts with the CLI executable. The CLI is signed by Edgeless Systems. To ensure non-repudiability for CLI releases, Edgeless Systems publishes corresponding signatures to the public ledger of the sigstore project. There's a step-by-step guide on how to verify CLI signatures based on sigstore.

-

The CLI contains the latest runtime measurements of the Constellation node image for all supported cloud platforms. In case a different version of the node image is to be used, the corresponding runtime measurements can be fetched using the CLI's fetch-measurements command. This command downloads the runtime measurements and the corresponding signature from cdn.confidential.cloud. See for example the following files corresponding to node image v2.16.3:

- -

The CLI contains the long-term public key of Edgeless Systems to verify the signature of downloaded runtime measurements.

-

Cluster creation​

-

When a cluster is created, the CLI automatically verifies the runtime measurements of the first node using remote attestation. Based on this, the CLI and the first node set up a temporary TLS connection. This aTLS connection is used for two things:

-
    -
  1. The CLI sends the master secret of the to-be-created cluster to the CLI. The master secret is generated by the first node.
    2. -
  2. The first node sends a kubeconfig file with Kubernetes credentials to the CLI.
    3. -
-

After this, the aTLS connection is closed and the first node bootstraps the Kubernetes cluster. All subsequent interactions between the CLI and the cluster go via the Kubernetes API server running inside the cluster. The CLI (and other tools like kubectl) use the credentials referenced by the kubeconfig file to authenticate themselves towards the Kubernetes API server and to establish a mTLS connection.

-

The CLI connects to the Kubernetes API to write the runtime measurements for the applicable node image to etcd. The JoinService uses these runtime measurements to verify all nodes that join the cluster subsequently.

-

Chain of trust​

-

In summary, there's a chain of trust based on cryptographic signatures that goes from the user to the cluster via the CLI. This is illustrated in the following diagram.

- -

Upgrades​

-

Whenever a cluster is upgraded to a new version of the node image, the CLI sends the corresponding runtime measurements via the Kubernetes API server. The new runtime measurements are stored in etcd within the cluster and replace any previous runtime measurements. The new runtime measurements are then used automatically by the JoinService for the verification of new nodes.

Encrypted persistent storage

-

Confidential VMs provide runtime memory encryption to protect data in use. -In the context of Kubernetes, this is sufficient for the confidentiality and integrity of stateless services. -Consider a front-end web server, for example, that keeps all connection information cached in main memory. -No sensitive data is ever written to an insecure medium. -However, many real-world applications need some form of state or data-lake service that's connected to a persistent storage device and requires encryption at rest. -As described in Use persistent storage, cloud service providers (CSPs) use the container storage interface (CSI) to make their storage solutions available to Kubernetes workloads. -These CSI storage solutions often support some sort of encryption. -For example, Google Cloud encrypts data at rest by default, without any action required by the customer.

-

Cloud provider-managed encryption​

-

CSP-managed storage solutions encrypt the data in the cloud backend before writing it physically to disk. -In the context of confidential computing and Constellation, the CSP and its managed services aren't trusted. -Hence, cloud provider-managed encryption protects your data from offline hardware access to physical storage devices. -It doesn't protect it from anyone with infrastructure-level access to the storage backend or a malicious insider in the cloud platform. -Even with "bring your own key" or similar concepts, the CSP performs the encryption process with access to the keys and plaintext data.

-

In the security model of Constellation, securing persistent storage and thereby data at rest requires that all cryptographic operations are performed inside a trusted execution environment. -Consequently, using CSP-managed encryption of persistent storage usually isn't an option.

-

Constellation-managed encryption​

-

Constellation provides CSI drivers for storage solutions in all major clouds with built-in encryption support. -Block storage provisioned by the CSP is mapped using the dm-crypt, and optionally the dm-integrity, kernel modules, before it's formatted and accessed by the Kubernetes workloads. -All cryptographic operations happen inside the trusted environment of the confidential Constellation node.

-

Note that for integrity-protected disks, volume expansion isn't supported.

-

By default the driver uses data encryption keys (DEKs) issued by the Constellation KeyService. -The DEKs are in turn derived from the Constellation's key encryption key (KEK), which is directly derived from the master secret. -This is the recommended mode of operation, and also requires the least amount of setup by the cluster administrator.

-

Alternatively, the driver can be configured to use a key management system to store and access KEKs and DEKs.

-

Refer to keys and cryptography for more details on key management in Constellation.

-

Once deployed and configured, the CSI driver ensures transparent encryption and integrity of all persistent volumes provisioned via its storage class. -Data at rest is secured without any additional actions required by the developer.

-

Cryptographic algorithms​

-

This section gives an overview of the libraries, cryptographic algorithms, and their configurations, used in Constellation's CSI drivers.

-

dm-crypt​

-

To interact with the dm-crypt kernel module, Constellation uses libcryptsetup. -New devices are formatted as LUKS2 partitions with a sector size of 4096 bytes. -The used key derivation function is Argon2id with the recommended parameters for memory-constrained environments of 3 iterations and 64 MiB of memory, utilizing 4 parallel threads. -For encryption Constellation uses AES in XTS-Plain64. The key size is 512 bit.

-

dm-integrity​

-

To interact with the dm-integrity kernel module, Constellation uses libcryptsetup. -When enabled, the used data integrity algorithm is HMAC with SHA256 as the hash function. -The tag size is 32 Bytes.

-

Encrypted S3 object storage​

-

Constellation comes with a service that you can use to transparently retrofit client-side encryption to existing applications that use S3 (AWS or compatible) for storage. -To learn more, check out the s3proxy documentation.

Constellation images

-

Constellation uses a minimal version of Fedora as the operating system running inside confidential VMs. This Linux distribution is optimized for containers and designed to be stateless. -The Constellation images provide measured boot and an immutable filesystem.

-

Measured boot​

- -

Measured boot uses a Trusted Platform Module (TPM) to measure every part of the boot process. This allows for verification of the integrity of a running system at any point in time. To ensure correct measurements of every stage, each stage is responsible to measure the next stage before transitioning.

-

Firmware​

-

With confidential VMs, the firmware is the root of trust and is measured automatically at boot. After initialization, the firmware will load and measure the bootloader before executing it.

-

Bootloader​

-

The bootloader is the first modifiable part of the boot chain. The bootloader is tasked with loading the kernel, initramfs and setting the kernel command line. The Constellation bootloader measures these components before starting the kernel.

-

initramfs​

-

The initramfs is a small filesystem loaded to prepare the actual root filesystem. The Constellation initramfs maps the block device containing the root filesystem with dm-verity. The initramfs then mounts the root filesystem from the mapped block device.

-

dm-verity provides integrity checking using a cryptographic hash tree. When a block is read, its integrity is checked by verifying the tree against a trusted root hash. The initramfs reads this root hash from the previously measured kernel command line. Thus, if any block of the root filesystem's device is modified on disk, trying to read the modified block will result in a kernel panic at runtime.

-

After mounting the root filesystem, the initramfs will switch over and start the init process of the integrity-protected root filesystem.

-

State disk​

-

In addition to the read-only root filesystem, each Constellation node has a disk for storing state data. -This disk is mounted readable and writable by the initramfs and contains data that should persist across reboots. -Such data can contain sensitive information and, therefore, must be stored securely. -To that end, the state disk is protected by authenticated encryption. -See the section on keys and encryption for more information on the cryptographic primitives in use.

-

Kubernetes components​

-

During initialization, the Bootstrapper downloads and verifies the Kubernetes components as configured by the user. -They're stored on the state partition and can be updated once new releases need to be installed.

Key management and cryptographic primitives

-

Constellation protects and isolates your cluster and workloads. -To that end, cryptography is the foundation that ensures the confidentiality and integrity of all components. -Evaluating the security and compliance of Constellation requires a precise understanding of the cryptographic primitives and keys used. -The following gives an overview of the architecture and explains the technical details.

-

Confidential VMs​

-

Confidential VM (CVM) technology comes with hardware and software components for memory encryption, isolation, and remote attestation. -For details on the implementations and cryptographic soundness, refer to the hardware vendors' documentation and advisories.

-

Master secret​

-

The master secret is the cryptographic material used for deriving the clusterID and the key encryption key (KEK) for storage encryption. -It's generated during the bootstrapping of a Constellation cluster. -It can either be managed by Constellation or an external key management system. -In case of recovery, the master secret allows to decrypt the state and recover a Constellation cluster.

-

Cluster identity​

-

The identity of a Constellation cluster is represented by cryptographic measurements:

-

The base measurements represent the identity of a valid, uninitialized Constellation node. -They depend on the node image, but are otherwise the same for every Constellation cluster. -On node boot, they're determined using the CVM's attestation mechanism and measured boot up to the read-only root filesystem.

-

The clusterID represents the identity of a single initialized Constellation cluster. -It's derived from the master secret and a cryptographically random salt and unique for every Constellation cluster. -The Bootstrapper measures the clusterID into its own PCR before executing any code not measured as part of the base measurements. -See Node attestation for details.

-

The remote attestation statement of a Constellation cluster combines the base measurements and the clusterID for a verifiable, unspoofable, unique identity.

-

Network encryption​

-

Constellation encrypts all cluster network communication using the container network interface (CNI). -See network encryption for more details.

-

The Cilium agent running on each node establishes a secure WireGuard tunnel between it and all other known nodes in the cluster. -Each node creates its own Curve25519 encryption key pair and distributes its public key via Kubernetes. -A node uses another node's public key to decrypt and encrypt traffic from and to Cilium-managed endpoints running on that node. -Connections are always encrypted peer-to-peer using ChaCha20 with Poly1305. -WireGuard implements forward secrecy with key rotation every 2 minutes.

-

Storage encryption​

-

Constellation supports transparent encryption of persistent storage. -The Linux kernel's device mapper-based encryption features are used to encrypt the data on the block storage level. -Currently, the following primitives are used for block storage encryption:

- -

Adding primitives for integrity protection in the CVM attacker model are under active development and will be available in a future version of Constellation. -See encrypted storage for more details.

-

As a cluster administrator, when creating a cluster, you can use the Constellation installation program to select one of the following methods for key management:

-
    -
  • Constellation-managed key management
    • -
  • User-managed key management
    • -
-

Constellation-managed key management​

-

Key material and key derivation​

-

During the creation of a Constellation cluster, the cluster's master secret is used to derive a KEK. -This means creating two clusters with the same master secret will yield the same KEK. -Any data encryption key (DEK) is derived from the KEK via HKDF. -Note that the master secret is recommended to be unique for every cluster and shouldn't be reused (except in case of recovering a cluster).

-

State and storage​

-

The KEK is derived from the master secret during the initialization. -Subsequently, all other key material is derived from the KEK. -Given the same KEK, any DEK can be derived deterministically from a given identifier. -Hence, there is no need to store DEKs. They can be derived on demand. -After the KEK was derived, it's stored in memory only and never leaves the CVM context.

-

Availability​

-

Constellation-managed key management has the same availability as the underlying Kubernetes cluster. -Therefore, the KEK is stored in the distributed Kubernetes etcd storage to allow for unexpected but non-fatal (control-plane) node failure. -The etcd storage is backed by the encrypted and integrity protected state disk of the nodes.

-

Recovery​

-

Constellation clusters can be recovered in the event of a disaster, even when all node machines have been stopped and need to be rebooted. -For details on the process see the recovery workflow.

-

User-managed key management​

-

User-managed key management is under active development and will be available soon. -In scenarios where constellation-managed key management isn't an option, this mode allows you to keep full control of your keys. -For example, compliance requirements may force you to keep your KEKs in an on-prem key management system (KMS).

-

During the creation of a Constellation cluster, you specify a KEK present in a remote KMS. -This follows the common scheme of "bring your own key" (BYOK). -Constellation will support several KMSs for managing the storage and access of your KEK. -Initially, it will support the following KMSs:

- -

Storing the keys in Cloud KMS of AWS, Azure, or GCP binds the key usage to the particular cloud identity access management (IAM). -In the future, Constellation will support remote attestation-based access policies for Cloud KMS once available. -Note that using a Cloud KMS limits the isolation and protection to the guarantees of the particular offering.

-

KMIP support allows you to use your KMIP-compatible on-prem KMS and keep full control over your keys. -This follows the common scheme of "hold your own key" (HYOK).

-

The KEK is used to encrypt per-data "data encryption keys" (DEKs). -DEKs are generated to encrypt your data before storing it on persistent storage. -After being encrypted by the KEK, the DEKs are stored on dedicated cloud storage for persistence. -Currently, Constellation supports the following cloud storage options:

- -

The DEKs are only present in plaintext form in the encrypted main memory of the CVMs. -Similarly, the cryptographic operations for encrypting data before writing it to persistent storage are performed in the context of the CVMs.

-

Recovery and migration​

-

In the case of a disaster, the KEK can be used to decrypt the DEKs locally and subsequently use them to decrypt and retrieve the data. -In case of migration, configuring the same KEK will provide seamless migration of data. -Thus, only the DEK storage needs to be transferred to the new cluster alongside the encrypted data for seamless migration.

Microservices

-

Constellation takes care of bootstrapping and initializing a Confidential Kubernetes cluster. -During the lifetime of the cluster, it handles day 2 operations such as key management, remote attestation, and updates. -These features are provided by several microservices:

- -

The relations between microservices are shown in the following diagram:

- -

Bootstrapper​

-

The Bootstrapper is the first microservice launched after booting a Constellation node image. -It sets up that machine as a Kubernetes node and integrates that node into the Kubernetes cluster. -To this end, the Bootstrapper first downloads and verifies the Kubernetes components at the configured versions. -The Bootstrapper tries to find an existing cluster and if successful, communicates with the JoinService to join the node. -Otherwise, it waits for an initialization request to create a new Kubernetes cluster.

-

JoinService​

-

The JoinService runs as DaemonSet on each control-plane node. -New nodes (at cluster start, or later through autoscaling) send a request to the service over attested TLS (aTLS). -The JoinService verifies the new node's certificate and attestation statement. -If attestation is successful, the new node is supplied with an encryption key from the KeyService for its state disk, and a Kubernetes bootstrap token.

- -

VerificationService​

-

The VerificationService runs as DaemonSet on each node. -It provides user-facing functionality for remote attestation during the cluster's lifetime via an endpoint for verifying the cluster. -Read more about the hardware-based attestation feature of Constellation and how to verify a cluster on the client side.

-

KeyService​

-

The KeyService runs as DaemonSet on each control-plane node. -It implements the key management for the storage encryption keys in Constellation. These keys are used for the state disk of each node and the transparently encrypted storage for Kubernetes. -Depending on wether the constellation-managed or user-managed mode is used, the KeyService holds the key encryption key (KEK) directly or calls an external key management service (KMS) for key derivation respectively.

Network encryption

-

Constellation encrypts all pod communication using the container network interface (CNI). -To that end, Constellation deploys, configures, and operates the Cilium CNI plugin. -Cilium provides transparent encryption for all cluster traffic using either IPSec or WireGuard. -Currently, Constellation only supports WireGuard as the encryption engine. -You can read more about the cryptographic soundness of WireGuard in their white paper.

-

Cilium is actively working on implementing a feature called host-to-host encryption mode for WireGuard. -With host-to-host, all traffic between nodes will be tunneled via WireGuard (host-to-host, host-to-pod, pod-to-host, pod-to-pod). -Until the host-to-host feature is released, Constellation enables pod-to-pod encryption. -This mode encrypts all traffic between Kubernetes pods using WireGuard tunnels.

-

When using Cilium in the default setup but with encryption enabled, there is a known issue -that can cause pod-to-pod traffic to be unencrypted. -To mitigate this issue, Constellation adds a strict mode to Cilium's pod-to-pod encryption. -This mode changes the default behavior of traffic that's destined for an unknown endpoint to not be send out in plaintext, but instead being dropped. -The strict mode distinguishes between traffic that's send to a pod from traffic that's destined for a cluster-external endpoint by considering the pod's CIDR range.

-

Traffic originating from hosts isn't encrypted yet. -This mainly includes health checks from Kubernetes API server. -Also, traffic proxied over the API server via e.g. kubectl port-forward isn't encrypted.

Observability

-

In Kubernetes, observability is the ability to gain insight into the behavior and performance of applications. -It helps identify and resolve issues more effectively, ensuring stability and performance of Kubernetes workloads, reducing downtime and outages, and improving efficiency. -The "three pillars of observability" are logs, metrics, and traces.

-

In the context of Confidential Computing, observability is a delicate subject and needs to be applied such that it doesn't leak any sensitive information. -The following gives an overview of where and how you can apply standard observability tools in Constellation.

-

Cloud resource monitoring​

-

While inaccessible, Constellation's nodes are still visible as black box VMs to the hypervisor. -Resource consumption, such as memory and CPU utilization, can be monitored from the outside and observed via the cloud platforms directly. -Similarly, other resources, such as storage and network and their respective metrics, are visible via the cloud platform.

-

Metrics​

-

Metrics are numeric representations of data measured over intervals of time. They're essential for understanding system health and gaining insights using telemetry signals.

-

By default, Constellation exposes the metrics for Kubernetes system components inside the cluster. -Similarly, the etcd metrics endpoints are exposed inside the cluster. -These metrics endpoints can be disabled.

-

You can collect these cluster-internal metrics via tools such as Prometheus or the Elastic Stack.

-

Constellation's CNI Cilium also supports metrics via Prometheus endpoints. -However, in Constellation, they're disabled by default and must be enabled first.

-

Logs​

-

Logs represent discrete events that usually describe what's happening with your service. -The payload is an actual message emitted from your system along with a metadata section containing a timestamp, labels, and tracking identifiers.

-

System logs​

-

Detailed system-level logs are accessible via /var/log and journald on the nodes directly. -They can be collected from there, for example, via Filebeat and Logstash, which are tools of the Elastic Stack.

-

In case of an error during the initialization, the CLI automatically collects the Bootstrapper logs and returns these as a file for troubleshooting. Here is an example of such an event:

-
Cluster initialization failed. This error is not recoverable.
Terminate your cluster and try again.
Fetched bootstrapper logs are stored in "constellation-cluster.log"
-

Kubernetes logs​

-

Constellation supports the Kubernetes logging architecture. -By default, logs are written to the nodes' encrypted state disks. -These include the Pod and container logs and the system component logs.

-

Constellation services run as Pods inside the kube-system namespace and use the standard container logging mechanism. -The same applies for the Cilium Pods.

-

You can collect logs from within the cluster via tools such as Fluentd, Loki, or the Elastic Stack.

-

Traces​

-

Modern systems are implemented as interconnected complex and distributed microservices. Understanding request flows and system communications is challenging, mainly because all systems in a chain need to be modified to propagate tracing information. Distributed tracing is a new approach to increasing observability and understanding performance bottlenecks. A trace represents consecutive events that reflect an end-to-end request path in a distributed system.

-

Constellation supports traces for Kubernetes system components. -By default, they're disabled and need to be enabled first.

-

Similarly, Cilium can be enabled to export traces.

-

You can collect these traces via tools such as Jaeger or Zipkin.

-

Integrations​

-

Platforms and SaaS solutions such as Datadog, logz.io, Dynatrace, or New Relic facilitate the observability challenge for Kubernetes and provide all-in-one SaaS solutions. -They install agents into the cluster that collect metrics, logs, and tracing information and upload them into the data lake of the platform. -Technically, the agent-based approach is compatible with Constellation, and attaching these platforms is straightforward. -However, you need to evaluate if the exported data might violate Constellation's compliance and privacy guarantees by uploading them to a third-party platform.

Orchestrating Constellation clusters

-

You can use the CLI to create a cluster on the supported cloud platforms. -The CLI provisions the resources in your cloud environment and initiates the initialization of your cluster. -It uses a set of parameters and an optional configuration file to manage your cluster installation. -The CLI is also used for updating your cluster.

-

Workspaces​

-

Each Constellation cluster has an associated workspace. -The workspace is where data such as the Constellation state and config files are stored. -Each workspace is associated with a single cluster and configuration. -The CLI stores state in the local filesystem making the current directory the active workspace. -Multiple clusters require multiple workspaces, hence, multiple directories. -Note that every operation on a cluster always has to be performed from the directory associated with its workspace.

-

You may copy files from the workspace to other locations, -but you shouldn't move or delete them while the cluster is still being used. -The Constellation CLI takes care of managing the workspace. -Only when a cluster was terminated, and you are sure the files aren't needed anymore, should you remove a workspace.

-

Cluster creation process​

-

To allow for fine-grained configuration of your cluster and cloud environment, Constellation supports an extensive configuration file with strong defaults. Generating the configuration file is typically the first thing you do in the workspace.

-

Altogether, the following files are generated during the creation of a Constellation cluster and stored in the current workspace:

-
    -
  • a configuration file
    • -
  • a state file
    • -
  • a Base64-encoded master secret
    • -
  • Terraform artifacts, stored in subdirectories
    • -
  • a Kubernetes kubeconfig file.
    • -
-

After the initialization of your cluster, the CLI will provide you with a Kubernetes kubeconfig file. -This file grants you access to your Kubernetes cluster and configures the kubectl tool. -In addition, the cluster's identifier is returned and stored in the state file.

-

Creation process details​

-
    -
  1. The CLI apply command first creates the confidential VM (CVM) resources in your cloud environment and configures the network
    2. -
  2. Each CVM boots the Constellation node image and measures every component in the boot chain
    3. -
  3. The first microservice launched in each node is the Bootstrapper
    4. -
  4. The Bootstrapper waits until it either receives an initialization request or discovers an initialized cluster
    5. -
  5. The CLI then connects to the Bootstrapper of a selected node, sends the configuration, and initiates the initialization of the cluster
    6. -
  6. The Bootstrapper of that node initializes the Kubernetes cluster and deploys the other Constellation microservices including the JoinService
    7. -
  7. Subsequently, the Bootstrappers of the other nodes discover the initialized cluster and send join requests to the JoinService
    8. -
  8. As part of the join request each node includes an attestation statement of its boot measurements as authentication
    9. -
  9. The JoinService verifies the attestation statements and joins the nodes to the Kubernetes cluster
    10. -
  10. This process is repeated for every node joining the cluster later (e.g., through autoscaling)
    11. -
-

Post-installation configuration​

-

Post-installation the CLI provides a configuration for accessing the cluster using the Kubernetes API. -The kubeconfig file provides the credentials and configuration for connecting and authenticating to the API server. -Once configured, orchestrate the Kubernetes cluster via kubectl.

-

After the initialization, the CLI will present you with a couple of tokens:

-
    -
  • The master secret (stored in the constellation-mastersecret.json file by default)
    • -
  • The clusterID of your cluster in Base64 encoding
    • -
-

You can read more about these values and their meaning in the guide on cluster identity.

-

The master secret must be kept secret and can be used to recover your cluster. -Instead of managing this secret manually, you can use your key management solution of choice with Constellation.

-

The clusterID uniquely identifies a cluster and can be used to verify your cluster.

-

Upgrades​

-

Constellation images and microservices may need to be upgraded to new versions during the lifetime of a cluster. -Constellation implements a rolling update mechanism ensuring no downtime of the control or data plane. -You can upgrade a Constellation cluster with a single operation by using the CLI. -For step-by-step instructions on how to do this, refer to Upgrade your cluster.

-

Attestation of upgrades​

-

With every new image, corresponding measurements are released. -During an update procedure, the CLI provides new measurements to the JoinService securely. -New measurements for an updated image are automatically pulled and verified by the CLI following the supply chain security concept of Constellation. -The attestation section describes in detail how these measurements are then used by the JoinService for the attestation of nodes.

This release primarily introduces new features, but may also include security or performance improvements. The MINOR version will be incremented as part of this release.

-

Additional PATCH releases may be created on demand, to fix security issues or bugs before the next MINOR release window.

-

New releases are published on GitHub.

-

Kubernetes support policy​

-

Constellation is aligned to the version support policy of Kubernetes, and therefore usually supports the most recent three minor versions. -When a new minor version of Kubernetes is released, support is added to the next Constellation release, and that version then supports four Kubernetes versions. -Subsequent Constellation releases drop support for the oldest (and deprecated) Kubernetes version.

-

The following Kubernetes versions are currently supported:

-
    -
  • v1.29.15
    • -
  • v1.30.11
    • -
  • v1.31.7
    • -

Basics

📄️ Security benefits

Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

The pod spec includes the hostAliases key, which adds an entry to the pod's /etc/hosts. -The entry forwards all requests for any of the currently defined AWS regions to the Kubernetes service s3proxy-service. -If you followed the s3proxy Deployment guide, this service points to a s3proxy pod.

-

The deployment specifies all regions explicitly to prevent accidental data leaks. -If one of your buckets were located in a region that's not part of the hostAliases key, traffic towards those buckets would not be redirected to s3proxy. -Similarly, if you want to exclude data for specific regions from going through s3proxy you can remove those regions from the deployment.

-

The spec also includes a volume mount for the TLS certificate and adds it to the pod's certificate trust store. -The volume is called ca-cert. -The key ca.crt of that volume is mounted to /etc/ssl/certs/kube-ca.crt, which is the default certificate trust store location for that container's OpenSSL library. -Not adding the CA certificate will result in TLS authentication errors.

-
    -
  1. Apply the file: kubectl apply -f deployment-filestash.yaml
    2. -
-

Afterward, you can use a port forward to access the Filestash pod: -kubectl port-forward pod/$(kubectl get pod --selector='app=filestash' -o=jsonpath='{.items[*].metadata.name}') 8334:8334

-
    -
  1. -

    After browsing to localhost:8443, Filestash will ask you to set an administrator password. -After setting it, you can directly leave the admin area by clicking the blue cloud symbol in the top left corner. -Subsequently, you can select S3 as storage backend and enter your credentials. -This will bring you to an overview of your buckets. -If you want to deploy Filestash in production, take a look at its documentation.

    -
    2. -
  2. -

    To see the logs of s3proxy intercepting requests made to S3, run: kubectl logs -f pod/$(kubectl get pod --selector='app=s3proxy' -o=jsonpath='{.items[*].metadata.name}') -Look out for log messages labeled intercepting. -There is one such log message for each message that's encrypted, decrypted, or blocked.

    -
    3. -
  3. -

    Once you have uploaded a file with Filestash, you should be able to view the file in Filestash. -However, if you go to the AWS S3 Web UI and download the file you just uploaded in Filestash, you won't be able to read it. -Another way to spot encrypted files without downloading them is to click on a file, scroll to the Metadata section, and look for the header named x-amz-meta-constellation-encryption. -This header holds the encrypted data encryption key of the object and is only present on objects that are encrypted by s3proxy.

Horizontal Pod Autoscaling

-

This example demonstrates Constellation's autoscaling capabilities. It's based on the Kubernetes HorizontalPodAutoscaler Walkthrough. During the following steps, Constellation will spawn new VMs on demand, verify them, add them to the cluster, and delete them again when the load has settled down.

-

Requirements​

-

The cluster needs to be initialized with Kubernetes 1.23 or later. In addition, autoscaling must be enabled to enable Constellation to assign new nodes dynamically.

-

Just for this example specifically, the cluster should have as few worker nodes in the beginning as possible. Start with a small cluster with only one low-powered node for the control-plane node and one low-powered worker node.

-
info

We tested the example using instances of types Standard_DC4as_v5 on Azure and n2d-standard-4 on GCP.

-

Setup​

-
    -
  1. -

    Install the Kubernetes Metrics Server:

    -
    kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
    -
    2. -
  2. -

    Deploy the HPA example server that's supposed to be scaled under load.

    -

    This manifest is similar to the one from the Kubernetes HPA walkthrough, but with increased CPU limits and requests to facilitate the triggering of node scaling events.

    Create a HorizontalPodAutoscaler.

    -

    Set an average CPU usage across all Pods of 20% to see one additional worker node being created later. Note that the CPU usage isn't related to the host CPU usage, but rather to the requested CPU capacities (20% of 600 milli-cores CPU across all Pods). See the original tutorial for more information on the HPA configuration.

    -
    kubectl autoscale deployment php-apache --cpu-percent=20 --min=1 --max=10
    -
    4. -
  4. -

    Create a Pod that generates load on the server:

    -
    kubectl run -i --tty load-generator --rm --image=busybox:1.28 --restart=Never -- /bin/sh -c "while true; do wget -q -O- http://php-apache; done"
    -
    5. -
  5. -

    Wait a few minutes until new nodes are added to the cluster. You can monitor the state of the HorizontalPodAutoscaler, the list of nodes, and the behavior of the autoscaler.

    -
    6. -
  6. -

    To stop the load generator, press CTRL+C and run:

    -
    kubectl delete pod load-generator
    -
    7. -
  7. -

    The cluster-autoscaler checks every few minutes if nodes are underutilized. It will taint such candidates for removal and wait additional 10 minutes before the nodes are eventually removed and deallocated. The whole process can take about 20 minutes.

    -
    8. -
-

Monitoring​

-
tip

For better observability, run the listed commands in different tabs in your terminal.

-

You can watch the status of the HorizontalPodAutoscaler with the current CPU usage, the target CPU limit, and the number of replicas created with:

-
kubectl get hpa php-apache --watch
-

From time to time compare the list of nodes to check the behavior of the autoscaler:

-
kubectl get nodes
-

For deeper insights, see the logs of the autoscaler Pod, which contains more details about the scaling decision process:

-
kubectl logs -f deployment/constellation-cluster-autoscaler -n kube-system

First steps with a local cluster

-

A local cluster lets you deploy and test Constellation without a cloud subscription. -You have two options:

-
    -
  • Use MiniConstellation to automatically deploy a two-node cluster.
    • -
  • For more fine-grained control, create the cluster using the QEMU provider.
    • -
-

Both options use virtualization to create a local cluster with control-plane nodes and worker nodes. They don't require hardware with Confidential VM (CVM) support. For attestation, they currently use a software-based vTPM provided by KVM/QEMU.

-

You need an x64 machine with a Linux OS. -You can use a VM, but it needs nested virtualization.

-

Prerequisites​

-
    -
  • Machine requirements: -
      -
    • An x86-64 CPU with at least 4 cores (6 cores are recommended)
      • -
    • At least 4 GB RAM (6 GB are recommended)
      • -
    • 20 GB of free disk space
      • -
    • Hardware virtualization enabled in the BIOS/UEFI (often referred to as Intel VT-x or AMD-V/SVM) / nested-virtualization support when using a VM
      • -
    -
    • -
  • Software requirements: - -
    • -
-

Software installation on Ubuntu​

-
# install Docker
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt update
sudo apt install docker-ce
# install other dependencies
sudo apt install xsltproc
sudo snap install kubectl --classic
# install Constellation CLI
curl -LO https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64
sudo install constellation-linux-amd64 /usr/local/bin/constellation
# do not drop forwarded packages
sudo iptables -P FORWARD ACCEPT
-

Create a cluster​

-

With the constellation mini command, you can deploy and test Constellation locally. This mode is called MiniConstellation. Conceptually, MiniConstellation is similar to MicroK8s, K3s, and minikube.

caution

MiniConstellation has specific soft- and hardware requirements such as a Linux OS running on an x86-64 CPU. Pay attention to all prerequisites when setting up.

note

Since MiniConstellation runs on your local system, cloud features such as load balancing, -attaching persistent storage, or autoscaling aren't available.

The following creates your MiniConstellation cluster (may take up to 10 minutes to complete):

constellation mini up

This will configure your current directory as the workspace for this cluster. -All constellation commands concerning this cluster need to be issued from this directory.

-

Connect to the cluster​

-

Your cluster initially consists of a single control-plane node:

-
$ kubectl get nodes
NAME              STATUS   ROLES           AGE   VERSION
control-plane-0   Ready    control-plane   66s   v1.24.6
-

Additional nodes will request to join the cluster shortly. Before each additional node is allowed to join the cluster, its state is verified using remote attestation by the JoinService. -If verification passes successfully, the new node receives keys and certificates to join the cluster.

-

You can follow this process by viewing the logs of the JoinService:

-
$ kubectl logs -n kube-system daemonsets/join-service -f
{"level":"INFO","ts":"2022-10-14T09:32:20Z","caller":"cmd/main.go:48","msg":"Constellation Node Join Service","version":"2.1.0","cloudProvider":"qemu"}
{"level":"INFO","ts":"2022-10-14T09:32:20Z","logger":"validator","caller":"watcher/validator.go:96","msg":"Updating expected measurements"}
...
-

Once all nodes have joined your cluster, it may take a couple of minutes for all resources to become available. -You can check on the state of your cluster by running the following:

-
$ kubectl get nodes
NAME              STATUS   ROLES           AGE     VERSION
control-plane-0   Ready    control-plane   2m59s   v1.24.6
worker-0          Ready    <none>          32s     v1.24.6
-

Deploy a sample application​

-
    -
  1. Deploy the emojivoto app
    2. -
-
kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
-
    -
  1. Expose the frontend service locally
    2. -
-
kubectl wait --for=condition=available --timeout=60s -n emojivoto --all deployments
kubectl -n emojivoto port-forward svc/web-svc 8080:80 &
curl http://localhost:8080
kill %1
-

Terminate your cluster​

-

Once you are done, you can clean up the created resources using the following command:

constellation mini down

This will destroy your cluster and clean up your workspace. -The VM image and cluster configuration file (constellation-conf.yaml) will be kept and may be reused to create new clusters.

-

Troubleshooting​

-

Make sure to use the latest release and check out the known issues.

-

VMs have no internet access / CLI remains in "Initializing cluster" state​

-

iptables rules may prevent your VMs from accessing the internet. -Make sure your rules aren't dropping forwarded packages.

-

List your rules:

-
sudo iptables -S
-

The output may look similar to the following:

-
-P INPUT ACCEPT
-P FORWARD DROP
-P OUTPUT ACCEPT
-N DOCKER
-N DOCKER-ISOLATION-STAGE-1
-N DOCKER-ISOLATION-STAGE-2
-N DOCKER-USER
-

If your FORWARD chain is set to DROP, you need to update your rules:

-
sudo iptables -P FORWARD ACCEPT

First steps with Constellation

-

The following steps guide you through the process of creating a cluster and deploying a sample app. This example assumes that you have successfully installed and set up Constellation, -and have access to a cloud subscription.

-
tip

If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

-
note

If you encounter any problem with the following steps, make sure to use the latest release and check out the known issues.

-

Create a cluster​

-
    -
  1. -

    Create the configuration file and state file for your cloud provider. If you are following the steps of this guide, there is no need to edit the file.

    -
    constellation config generate aws
    -
    2. -
  2. -

    Create your IAM configuration.

    -
    constellation iam create aws --zone=us-east-2a --prefix=constellTest --update-config

    This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created. It also updates the configuration file constellation-conf.yaml in your current directory with the IAM values filled in.

    Depending on the attestation variant selected on config generation, different regions are available. -AMD SEV-SNP machines (requires the default attestation variant awsSEVSNP) are currently available in the following regions:

      -
    • eu-west-1
      • -
    • us-east-2
      • -

    You can find a list of regions that support AMD SEV-SNP in AWS's documentation.

    NitroTPM machines (requires the attestation variant awsNitroTPM) are available in all regions. -Constellation OS images are currently replicated to the following regions:

      -
    • eu-central-1
      • -
    • eu-west-1
      • -
    • eu-west-3
      • -
    • us-east-2
      • -
    • ap-south-1
      • -

    If you require the OS image to be available in another region, let us know.

    You can find a list of all regions in AWS's documentation.

    curl http://localhost:8080
    kill %1
    -
    3. -
-

Terminate your cluster​

-

Use the CLI to terminate your cluster. If you manually used Terraform to manage your cloud resources, follow the corresponding instructions in the Terminate workflow.

-
constellation terminate
-

This should give the following output:

-
$ constellation terminate
You are about to terminate a Constellation cluster.
All of its associated resources will be DESTROYED.
This action is irreversible and ALL DATA WILL BE LOST.
Do you want to continue? [y/n]:
-

Confirm with y to terminate the cluster:

-

Installation and setup

-

Constellation runs entirely in your cloud environment and can be controlled via a dedicated command-line interface (CLI) or a Terraform provider.

-

Prerequisites​

-

Make sure the following requirements are met:

-
    -
  • Your machine is running Linux, macOS, or Windows
    • -
  • You have admin rights on your machine
    • -
  • kubectl is installed
    • -
  • Your CSP is Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), or STACKIT
    • -
-

Install the Constellation CLI​

-
tip

If you prefer to use Terraform, you can alternatively use the Terraform provider to manage the cluster's lifecycle.

-

The CLI executable is available at GitHub. -Install it with the following commands:

-
    -
  1. Download the CLI:
    2. -
curl -LO https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64
    -
  1. -

    Verify the signature (optional)

    -
    2. -
  2. -

    Install the CLI to your PATH:

    -
    3. -
sudo install constellation-linux-amd64 /usr/local/bin/constellation
-
tip

The CLI supports autocompletion for various shells. To set it up, run constellation completion and follow the given steps.

-

Set up cloud credentials​

-

Constellation makes authenticated calls to the CSP API. Therefore, you need to set up Constellation with the credentials for your CSP.

-
tip

If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

-

Required permissions​

-

To set up a Constellation cluster, you need to perform two tasks that require permissions: create the infrastructure and create roles for cluster nodes. Both of these actions can be performed by different users, e.g., an administrator to create roles and a DevOps engineer to create the infrastructure.

To create the IAM configuration for Constellation, you need the following permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ec2:DescribeAccountAttributes",
                "iam:AddRoleToInstanceProfile",
                "iam:AttachRolePolicy",
                "iam:CreateInstanceProfile",
                "iam:CreatePolicy",
                "iam:CreateRole",
                "iam:DeleteInstanceProfile",
                "iam:DeletePolicy",
                "iam:DeletePolicyVersion",
                "iam:DeleteRole",
                "iam:DetachRolePolicy",
                "iam:GetInstanceProfile",
                "iam:GetPolicy",
                "iam:GetPolicyVersion",
                "iam:GetRole",
                "iam:ListAttachedRolePolicies",
                "iam:ListInstanceProfilesForRole",
                "iam:ListPolicyVersions",
                "iam:ListRolePolicies",
                "iam:PassRole",
                "iam:RemoveRoleFromInstanceProfile",
                "sts:GetCallerIdentity"
            ],
            "Resource": "*"
        }
    ]
}

The built-in AdministratorAccess policy is a superset of these permissions.

To create a Constellation cluster, see the permissions of main.tf.

The built-in PowerUserAccess policy is a superset of these permissions.

Follow Amazon's guide on understanding and managing policies.

-

Authentication​

-

You need to authenticate with your CSP. The following lists the required steps for testing and production environments.

-
note

The steps for a testing environment are simpler. However, they may expose secrets to the CSP. If in doubt, follow the production steps.

-

Testing

You can use the AWS CloudShell. Make sure you are authorized to use it.

Production

Use the latest version of the AWS CLI on a trusted machine:

aws configure

Options and first steps are described in the AWS CLI documentation.

-

Next steps​

-

You are now ready to deploy your first confidential Kubernetes cluster and application.

Using Constellation via Cloud Marketplaces

-

Constellation is available through the Marketplaces of AWS, Azure, GCP, and STACKIT. This allows you to create self-managed Constellation clusters that are billed on a pay-per-use basis (hourly, per vCPU) with your CSP account. You can still get direct support by Edgeless Systems. For more information, please contact us.

-

This document explains how to run Constellation with the dynamically billed cloud marketplace images.

-

To use Constellation's marketplace images, ensure that you are subscribed to the marketplace offering through the web portal.

Then, enable the use of marketplace images in your Constellation constellation-conf.yaml config file:

yq eval -i ".provider.aws.useMarketplaceImage = true" constellation-conf.yaml
-

Ensure that the cluster uses an official release image version (i.e., .image=vX.Y.Z in the constellation-conf.yaml file).

-

From there, you can proceed with the cluster creation as usual.

Introduction

-

Welcome to the documentation of Constellation! Constellation is a Kubernetes engine that aims to provide the best possible data security.

-

Constellation concept

-

Constellation shields your entire Kubernetes cluster from the underlying cloud infrastructure. Everything inside is always encrypted, including at runtime in memory. For this, Constellation leverages a technology called confidential computing and more specifically Confidential VMs.

-
tip

See the 📄whitepaper for more information on confidential computing.

-

Goals​

-

From a security perspective, Constellation is designed to keep all data always encrypted and to prevent any access from the underlying (cloud) infrastructure. This includes access from datacenter employees, privileged cloud admins, and attackers coming through the infrastructure. Such attackers could be malicious co-tenants escalating their privileges or hackers who managed to compromise a cloud server.

-

From a DevOps perspective, Constellation is designed to work just like what you would expect from a modern Kubernetes engine.

-

Use cases​

-

Constellation provides unique security features and benefits. The core use cases are:

-
    -
  • Increasing the overall security of your clusters
    • -
  • Increasing the trustworthiness of your SaaS offerings
    • -
  • Moving sensitive workloads from on-prem to the cloud
    • -
  • Meeting regulatory requirements
    • -
-

Next steps​

-

You can learn more about the concept of Confidential Kubernetes, features, security benefits, and performance of Constellation in the Basics section. To jump right into the action head to Getting started.

Feature status of clouds

-

What works on which cloud? Currently, Confidential VMs (CVMs) are available in varying quality on the different clouds and software stacks.

-

For Constellation, the ideal environment provides the following:

-
    -
  1. Ability to run arbitrary software and images inside CVMs
    2. -
  2. CVMs based on AMD SEV-SNP (available in EPYC CPUs since the Milan generation) or Intel TDX (available in Xeon CPUs since the Sapphire Rapids generation)
    3. -
  3. Ability for CVM guests to obtain raw hardware attestation statements
    4. -
  4. Reviewable, open-source firmware inside CVMs
    5. -
  5. Capability of the firmware to attest the integrity of the code it passes control to, e.g., with an embedded virtual TPM (vTPM)
    6. -
-

(1) is a functional must-have. (2)--(5) are required for remote attestation that fully keeps the infrastructure/cloud out. Constellation can work without them or with approximations, but won't protect against certain privileged attackers anymore.

-

The following table summarizes the state of features for different infrastructures.

-

Amazon Web Services (AWS)​

-

Amazon EC2 supports AMD SEV-SNP. -Regarding (3), AWS provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the NitroTPM for measured boot, which is a vTPM managed by the Nitro hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the firmware is open source and can be reproducibly built.

-

Microsoft Azure​

-

With its CVM offering, Azure provides the best foundations for Constellation. -Regarding (3), Azure provides direct access to attestation statements. -The firmware runs in an isolated domain inside the CVM and exposes a vTPM (5), but it's closed source (4). -On SEV-SNP, Azure uses VM Privilege Level (VMPL) isolation for the separation of firmware and the rest of the VM; on TDX, they use TD partitioning. -This firmware is signed by Azure. -The signature is reflected in the attestation statements of CVMs. -Thus, the Azure closed-source firmware becomes part of Constellation's trusted computing base (TCB).

-

* Recently, Azure announced the open source paravisor OpenHCL. It's the foundation for fully open source and verifiable CVM firmware. Once Azure provides their CVM firmware with reproducible builds based on OpenHCL, (4) switches from No to Yes. Constellation will support OpenHCL based firmware on Azure in the future.

-

Google Cloud Platform (GCP)​

-

The CVMs Generally Available in GCP are based on AMD SEV-ES or SEV-SNP. -Regarding (3), with their SEV-SNP offering Google provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the Shielded VM vTPM for measured boot, which is a vTPM managed by Google's hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the CVMs still include closed-source firmware.

-

TDX on Google is in public preview. -With it, Constellation would have a similar TCB and attestation flow as with the current SEV-SNP offering.

-

STACKIT​

-

STACKIT Compute Engine supports AMD SEV-ES. A vTPM is used for measured boot, which is a vTPM managed by STACKIT's hypervisor. Hence, the hypervisor is currently part of Constellation's TCB.

-

OpenStack​

-

OpenStack is an open-source cloud and infrastructure management software. It's used by many smaller CSPs and datacenters. In the latest Yoga version, OpenStack has basic support for CVMs. However, much depends on the employed kernel and hypervisor. Features (2)--(4) are likely to be a Yes with Linux kernel version 6.2. Thus, going forward, OpenStack on corresponding AMD or Intel hardware will be a viable underpinning for Constellation.

-

Conclusion​

-

The different clouds and software like the Linux kernel and OpenStack are in the process of building out their support for state-of-the-art CVMs. Azure has already most features in place. For Constellation, the status quo means that the TCB has different shapes on different infrastructures. With broad SEV-SNP support coming to the Linux kernel, we soon expect a normalization of features across infrastructures.

Confidential Kubernetes

-

We use the term Confidential Kubernetes to refer to the concept of using confidential-computing technology to shield entire Kubernetes clusters from the infrastructure. The three defining properties of this concept are:

-
    -
  1. Workload shielding: the confidentiality and integrity of all workload-related data and code are enforced.
    2. -
  2. Control plane shielding: the confidentiality and integrity of the cluster's control plane, state, and workload configuration are enforced.
    3. -
  3. Attestation and verifiability: the two properties above can be verified remotely based on hardware-rooted cryptographic certificates.
    4. -
-

Each of the above properties is equally important. Only with all three in conjunction, an entire cluster can be shielded without gaps.

-

Constellation security features​

-

Constellation implements the Confidential Kubernetes concept with the following security features.

-
    -
  • Runtime encryption: Constellation runs all Kubernetes nodes inside Confidential VMs (CVMs). This gives runtime encryption for the entire cluster.
    • -
  • Network and storage encryption: Constellation augments this with transparent encryption of the network, persistent storage, and other managed storage like AWS S3. Thus, workloads and control plane are truly end-to-end encrypted: at rest, in transit, and at runtime.
    • -
  • Transparent key management: Constellation manages the corresponding cryptographic keys inside CVMs.
    • -
  • Node attestation and verification: Constellation verifies the integrity of each new CVM-based node using remote attestation. Only "good" nodes receive the cryptographic keys required to access the network and storage of a cluster.
    • -
  • Confidential computing-optimized images: A node is "good" if it's running a signed Constellation node image inside a CVM and is in the expected state. (Node images are hardware-measured during boot. The measurements are reflected in the attestation statements that are produced by nodes and verified by Constellation.)
    • -
  • "Whole cluster" attestation: Towards the DevOps engineer, Constellation provides a single hardware-rooted certificate from which all of the above can be verified.
    • -
-

With the above, Constellation wraps an entire cluster into one coherent and verifiable confidential context. The concept is depicted in the following.

-

Confidential Kubernetes

-

Comparison: Managed Kubernetes with CVMs​

-

In comparison, managed Kubernetes with CVMs, as it's for example offered in AKS and GKE, only provides runtime encryption for certain worker nodes. Here, each worker node is a separate (and typically unverified) confidential context. This only provides limited security benefits as it only prevents direct access to a worker node's memory. The large majority of potential attacks through the infrastructure remain unaffected. This includes attacks through the control plane, access to external key management, and the corruption of worker node images. This leaves many problems unsolved. For instance, Node A has no means to verify if Node B is "good" and if it's OK to share data with it. Consequently, this approach leaves a large attack surface, as is depicted in the following.

-

Concept: Managed Kubernetes plus CVMs

HashiCorp Vault​

-

HashiCorp Vault is a distributed secrets management software that can be deployed to Kubernetes. -HashiCorp maintains a benchmarking tool for vault, vault-benchmark. -Vault-benchmark generates load on a Vault deployment and measures response times.

-

This article describes the results from running vault-benchmark on Constellation, AKS, and GKE. -You can find the setup for producing the data discussed in this article in the vault-benchmarks repository.

-

The Vault API used during benchmarking is the transits secret engine. -This allows services to send data to Vault for encryption, decryption, signing, and verification.

-

Results​

-

On each run, vault-benchmark sends requests and measures the latencies. -The measured latencies are aggregated through various statistical features. -After running the benchmark n times, the arithmetic mean over a subset of the reported statistics is calculated. -The selected features are arithmetic mean, 99th percentile, minimum, and maximum.

-

Arithmetic mean gives a general sense of the latency on each target. -The 99th percentile shows performance in (most likely) erroneous states. -Minimum and maximum mark the range within which latency varies each run.

-

The benchmark was configured with 1300 workers and 10 seconds per run. -Those numbers were chosen empirically. -The latency was stabilizing at 10 seconds runtime, not changing with further increase. -Increasing the number of workers beyond 1300 leads to request failures, marking the limit Vault was able to handle in this setup. -All results are based on 100 runs.

-

Impact of runtime encryption on compute performance

-

All nodes in a Constellation cluster are executed inside Confidential VMs (CVMs). Consequently, the performance of Constellation is inherently linked to the performance of these CVMs.

-

AMD and Azure benchmarking​

-

AMD and Azure have collectively released a performance benchmark for CVMs that utilize 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. This benchmark, which included a variety of mostly compute-intensive tests such as SPEC CPU 2017 and CoreMark, demonstrated that CVMs experience only minor performance degradation (ranging from 2% to 8%) when compared to standard VMs. Such results are indicative of the performance that can be expected from compute-intensive workloads running with Constellation on Azure.

-

AMD and Google benchmarking​

-

Similarly, AMD and Google have jointly released a performance benchmark for CVMs employing 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. With high-performance computing workloads such as WRF, NAMD, Ansys CFS, and Ansys LS_DYNA, they observed analogous findings, with only minor performance degradation (between 2% and 4%) compared to standard VMs. These outcomes are reflective of the performance that can be expected for compute-intensive workloads running with Constellation on GCP.

Results​

-

Network​

-

This section gives a thorough analysis of the network performance of Constellation, specifically focusing on measuring TCP and UDP bandwidth. -The benchmark measured the bandwidth of pod-to-pod and pod-to-service connections between two different nodes using iperf.

-

GKE and Constellation on GCP had a maximum network bandwidth of 10 Gbps. -AKS with Standard_D4as_v5 machines a maximum network bandwidth of 12.5 Gbps. -The Confidential VM equivalent Standard_DC4as_v5 currently has a network bandwidth of 1.25 Gbps. -Therefore, to make the test comparable, both AKS and Constellation on Azure were running with Standard_DC4as_v5 machines and 1.25 Gbps bandwidth.

-

Constellation on Azure and AKS used an MTU of 1500. -Constellation on GCP used an MTU of 8896. GKE used an MTU of 1450.

-

The difference in network bandwidth can largely be attributed to two factors.

- -

Pod-to-Pod​

-

In this scenario, the client Pod connects directly to the server pod via its IP address.

- -

The results for "Pod-to-Pod" on Azure are as follows:

-

Network Pod2Pod Azure benchmark graph

-

The results for "Pod-to-Pod" on GCP are as follows:

-

Network Pod2Pod GCP benchmark graph

-

Pod-to-Service​

-

In this scenario, the client Pod connects to the server Pod via a ClusterIP service. This is more relevant to real-world use cases.

- -

The results for "Pod-to-Pod" on Azure are as follows:

-

Network Pod2SVC Azure benchmark graph

-

The results for "Pod-to-Pod" on GCP are as follows:

-

Network Pod2SVC GCP benchmark graph

-

In our recent comparison of Constellation on GCP with GKE, Constellation has 58% less TCP bandwidth. However, UDP bandwidth was slightly better with Constellation, thanks to its higher MTU.

-

Similarly, when comparing Constellation on Azure with AKS using CVMs, Constellation achieved approximately 10% less TCP and 40% less UDP bandwidth.

-

Storage I/O​

-

Azure and GCP offer persistent storage for their Kubernetes services AKS and GKE via the Container Storage Interface (CSI). CSI storage in Kubernetes is available via PersistentVolumes (PV) and consumed via PersistentVolumeClaims (PVC). -Upon requesting persistent storage through a PVC, GKE and AKS will provision a PV as defined by a default storage class. -Constellation provides persistent storage on Azure and GCP that's encrypted on the CSI layer. -Similarly, upon a PVC request, Constellation will provision a PV via a default storage class.

-

For Constellation on Azure and AKS, the benchmark ran with Azure Disk storage Standard SSD of 400 GiB size. -The DC4as machine type with four cores provides the following maximum performance:

-
    -
  • 6400 (20000 burst) IOPS
    • -
  • 144 MB/s (600 MB/s burst) throughput
    • -
-

However, the performance is bound by the capabilities of the 512 GiB Standard SSD size (the size class of 400 GiB volumes):

-
    -
  • 500 (600 burst) IOPS
    • -
  • 60 MB/s (150 MB/s burst) throughput
    • -
-

For Constellation on GCP and GKE, the benchmark ran with Compute Engine Persistent Disk Storage pd-balanced of 400 GiB size. -The N2D machine type with four cores and pd-balanced provides the following maximum performance:

-
    -
  • 3,000 read IOPS
    • -
  • 15,000 write IOPS
    • -
  • 240 MB/s read throughput
    • -
  • 240 MB/s write throughput
    • -
-

However, the performance is bound by the capabilities of a Zonal balanced PD with 400 GiB size:

-
    -
  • 2400 read IOPS
    • -
  • 2400 write IOPS
    • -
  • 112 MB/s read throughput
    • -
  • 112 MB/s write throughput
    • -
-

The fio benchmark consists of several tests. -The benchmark used Kubestr to run fio in Kubernetes. -The default test performs randomized access patterns that accurately depict worst-case I/O scenarios for most applications.

-

The following fio settings were used:

-
    -
  • No Cloud caching
    • -
  • No OS caching
    • -
  • Single CPU
    • -
  • 60 seconds runtime
    • -
  • 10 seconds ramp-up time
    • -
  • 10 GiB file
    • -
  • IOPS: 4 KB blocks and 128 iodepth
    • -
  • Bandwidth: 1024 KB blocks and 128 iodepth
    • -
-

For more details, see the fio test configuration.

-

The results for IOPS on Azure are as follows:

-

I/O IOPS Azure benchmark graph

-

The results for IOPS on GCP are as follows:

-

I/O IOPS GCP benchmark graph

-

The results for bandwidth on Azure are as follows:

-

I/O bandwidth Azure benchmark graph

-

The results for bandwidth on GCP are as follows:

-

I/O bandwidth GCP benchmark graph

-

On GCP, the results exceed the maximum performance guarantees of the chosen disk type. There are two possible explanations for this. The first is that there may be cloud caching in place that isn't configurable. Alternatively, the underlying provisioned disk size may be larger than what was requested, resulting in higher performance boundaries.

-

When comparing Constellation on GCP with GKE, Constellation has similar bandwidth but about 10% less IOPS performance. On Azure, Constellation has similar IOPS performance compared to AKS, where both likely hit the maximum storage performance. However, Constellation has approximately 15% less read and write bandwidth.

-

Conclusion​

-

Despite the added security benefits that Constellation provides, it only incurs a slight performance overhead when compared to managed Kubernetes offerings such as AKS and GKE. In most compute benchmarks, Constellation is on par with it's alternatives. -While it may be slightly slower in certain I/O scenarios due to network and storage encryption, there is ongoing work to reduce this overhead to single digits.

-

For instance, storage encryption only adds between 10% to 15% overhead in terms of bandwidth and IOPS. -Meanwhile, the biggest performance impact that Constellation currently faces is network encryption, which can incur up to 58% overhead on a 10 Gbps network. -However, the Cilium team has conducted benchmarks with Cilium using WireGuard encryption on a 100 Gbps network that yielded over 15 Gbps. -We're confident that Constellation will provide a similar level of performance with an upcoming release.

-

Overall, Constellation strikes a great balance between security and performance, and we're continuously working to improve its performance capabilities while maintaining its high level of security.

Product features

-

Constellation is a Kubernetes engine that aims to provide the best possible data security in combination with enterprise-grade scalability and reliability features---and a smooth user experience.

-

From a security perspective, Constellation implements the Confidential Kubernetes concept and corresponding security features, which shield your entire cluster from the underlying infrastructure.

-

From an operational perspective, Constellation provides the following key features:

-
    -
  • Native support for different clouds: Constellation works on Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and STACKIT. Support for OpenStack-based environments is coming with a future release. Constellation securely interfaces with the cloud infrastructure to provide cluster autoscaling, dynamic persistent volumes, and service load balancing.
    • -
  • High availability: Constellation uses a multi-master architecture with a stacked etcd topology to ensure high availability.
    • -
  • Integrated Day-2 operations: Constellation lets you securely upgrade your cluster to a new release. It also lets you securely recover a failed cluster. Both with a single command.
    • -
  • Support for Terraform: Constellation includes a Terraform provider that lets you manage the full lifecycle of your cluster via Terraform.

Security benefits and threat model

-

Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

-

TCB comparison

-

Given this background, the following describes the concrete threat classes that Constellation addresses.

-

Insider access​

-

Employees and third-party contractors of cloud service providers (CSPs) have access to different layers of the cloud infrastructure. -This opens up a large attack surface where workloads and data can be read, copied, or manipulated. With Constellation, Kubernetes deployments are shielded from the infrastructure and thus such accesses are prevented.

-

Infrastructure-based attacks​

-

Malicious cloud users ("hackers") may break out of their tenancy and access other tenants' data. Advanced attackers may even be able to establish a permanent foothold within the infrastructure and access data over a longer period. Analogously to the insider access scenario, Constellation also prevents access to a deployment's data in this scenario.

-

Supply chain attacks​

-

Supply chain security is receiving lots of attention recently due to an increasing number of recorded attacks. For instance, a malicious actor could attempt to tamper Constellation node images (including Kubernetes and other software) before they're loaded in the confidential VMs of a cluster. Constellation uses remote attestation in conjunction with public transparency logs to prevent this.

-

In the future, Constellation will extend this feature to customer workloads. This will enable cluster owners to create auditable policies that precisely define which containers can run in a given deployment.

Migrations to v2.19.1​

-

Azure​

-
    -
  • During the upgrade, security rules are migrated and the old ones need to be cleaned up manually by the user. The below script shows how to delete them through the Azure CLI:
    • -
-
#!/usr/bin/env bash
name="<insert>"  # the name provided in the config
uid="<insert>"    # the cluster id can be retrieved via `yq '.infrastructure.uid' constellation-state.yaml`
resource_group="<insert>" # the RG can be retrieved via `yq '.provider.azure.resourceGroup' constellation-conf.yaml`

rules=(
  "kubernetes"
  "bootstrapper"
  "verify"
  "recovery"
  "join"
  "debugd"
  "konnectivity"
)

for rule in "${rules[@]}"; do
  echo "Deleting rule: ${rule}"
  az network nsg rule delete \
    --resource-group "${resource_group}" \
    --nsg-name "${name}-${uid}" \
    --name "${rule}"
done

echo "All specified rules have been deleted."

Migrating from CLI versions before 2.21.1​

-

AWS​

-
    -
  • AWS clusters that use LoadBalancer resources require more IAM permissions. Please upgrade your IAM roles using constellation iam upgrade apply. This will show necessary changes and apply them, if desired.
    • -
-

Migrating from CLI versions before 2.19.0​

-

Azure​

-
    -
  • To allow seamless upgrades on Azure when Kubernetes services of type LoadBalancer are deployed, the target -load balancer in which the cloud-controller-manager creates load balancing rules was changed. Instead of using the load balancer -created and maintained by the CLI's Terraform code, the cloud-controller-manager now creates its own load balancer in Azure. -If your Constellation has services of type LoadBalancer, please remove them before the upgrade and re-apply them -afterward.
    • -
-

Migrating from CLI versions before 2.18.0​

-
    -
  • The provider.azure.appClientID and provider.azure.appClientSecret fields are no longer supported and should be removed.
    • -
  • To keep using an existing UAMI, add the Owner permission with the scope of your resourceGroup.
    • -
  • Otherwise, simply create new Constellation IAM credentials and use the created UAMI.
    • -
  • To migrate the authentication for an existing cluster on Azure to an UAMI with the necessary permissions: -
      -
    1. Remove the aadClientId and aadClientSecret from the azureconfig secret.
      2. -
    2. Set useManagedIdentityExtension to true and use the userAssignedIdentity from the Constellation config for the value of userAssignedIdentityID.
      3. -
    3. Restart the CSI driver, cloud controller manager, cluster autoscaler, and Constellation operator pods.
      4. -
    -
    • -
-

Migrating from CLI versions before 2.10​

-
    -
  • AWS cluster upgrades require additional IAM permissions for the newly introduced aws-load-balancer-controller. Please upgrade your IAM roles using iam upgrade apply. This will show necessary changes and apply them, if desired.
    • -
  • The global nodeGroups field was added.
    • -
  • The fields instanceType, stateDiskSizeGB, and stateDiskType for each cloud provider are now part of the configuration of individual node groups.
    • -
  • The constellation create command no longer uses the flags --control-plane-count and --worker-count. Instead, the initial node count is configured per node group in the nodeGroups field.
    • -
-

Migrating from CLI versions before 2.9​

-
    -
  • The provider.azure.appClientID and provider.azure.clientSecretValue fields were removed to enforce migration to managed identity authentication
    • -
-

Migrating from CLI versions before 2.8​

-
    -
  • The measurements field for each cloud service provider was replaced with a global attestation field.
    • -
  • The confidentialVM, idKeyDigest, and enforceIdKeyDigest fields for the Azure cloud service provider were removed in favor of using the global attestation field.
    • -
  • The optional global field attestationVariant was replaced by the now required attestation field.
    • -
-

Migrating from CLI versions before 2.3​

-
    -
  • -

    The sshUsers field was deprecated in v2.2 and has been removed from the configuration in v2.3. -As an alternative for SSH, check the workflow section Connect to nodes.

    -
    • -
  • -

    The image field for each cloud service provider has been replaced with a global image field. Use the following mapping to migrate your configuration:

Supply chain levels for software artifacts (SLSA) adoption

-

Supply chain Levels for Software Artifacts, or SLSA (salsa) is a framework for improving and grading a project's build system and engineering processes. SLSA focuses on security improvements for source code storage as well as build system definition, execution, and observation. SLSA is structured in four levels. This page describes the adoption of SLSA for Constellation.

-
info

SLSA is still in alpha status. The presented levels and their requirements might change in the future. We will adopt any changes into our engineering processes, as they get defined.

-

Level 1 - Adopted​

-

Build - Scripted

-

All build steps are automated via Bazel and GitHub Actions.

-

Provenance - Available

-

Provenance for the CLI is generated using the slsa-github-generator.

-

Level 2 - Adopted​

-

Source - Version Controlled

-

Constellation is hosted on GitHub using git.

-

Build - Build Service

-

All builds are carried out by GitHub Actions.

-

Provenance - Authenticated

-

Provenance for the CLI is signed using the slsa-github-generator. Learn how to verify the CLI using the signed provenance, before using it for the first time.

-

Provenance - Service Generated

-

Provenance for the CLI is generated using the slsa-github-generator in GitHub Actions.

-

Level 3 - Adopted​

-

Source - Verified History

-

The Edgeless Systems GitHub organization requires two-factor authentication for all members.

-

Source - Retained Indefinitely

-

Since we use GitHub to host the repository, an external person can't modify or delete the history. Before a pull request can be merged, an explicit approval from an Edgeless Systems team member is required.

-

The same holds true for changes proposed by team members. Each change to main needs to be proposed via a pull request and requires at least one approval.

-

The Edgeless Systems GitHub organization admins control these settings and are able to make changes to the repository's history should legal requirements necessitate it. These changes require two-party approval following the obliterate policy.

-

Build - Build as Code

-

All build files for Constellation are stored in the same repository.

-

Build - Ephemeral Environment

-

All GitHub Action workflows are executed on GitHub-hosted runners. These runners are only available during workflow.

-

We currently don't use self-hosted runners.

-

Build - Isolated

-

As outlined in the previous section, we use GitHub-hosted runners, which provide a new, isolated and ephemeral environment for each build.

-

Additionally, the SLSA GitHub generator itself is run in an isolated workflow with the artifact hash as defined inputs.

-

Provenance - Non-falsifiable

-

As outlined by SLSA GitHub generator it already fulfills the non-falsifiable requirements for SLSA Level 3. The generated provenance is signed using sigstore with an OIDC based proof of identity.

-

Level 4 - In Progress​

-

We strive to adopt certain aspect of SLSA Level 4 that support our engineering process. At the same time, SLSA is still in alpha status and the biggest changes to SLSA are expected to be around Level 4.

Terraform usage

-

Terraform is an Infrastructure as Code (IaC) framework to manage cloud resources. This page explains how Constellation uses it internally and how advanced users may manually use it to have more control over the resource creation.

-
info

Information on this page is intended for users who are familiar with Terraform. -It's not required for common usage of Constellation. -See the Terraform documentation if you want to learn more about it.

-

Terraform state files​

-

Constellation keeps Terraform state files in subdirectories of the workspace together with the corresponding Terraform configuration files and metadata. -The subdirectories are created on the first Constellation CLI action that uses Terraform internally.

-

Currently, these subdirectories are:

-
    -
  • constellation-terraform - Terraform state files for the resources of the Constellation cluster
    • -
  • constellation-iam-terraform - Terraform state files for IAM configuration
    • -
-

As with all commands, commands that work with these files (e.g., apply, terminate, iam) have to be executed from the root of the cluster's workspace directory. You usually don't need and shouldn't manipulate or delete the subdirectories manually.

-

Interacting with Terraform manually​

-

Manual interaction with Terraform state created by Constellation (i.e., via the Terraform CLI) should only be performed by experienced users. It may lead to unrecoverable loss of cloud resources. For the majority of users and use cases, the interaction done by the Constellation CLI is sufficient.

-

Terraform debugging​

-

To debug Terraform issues, the Constellation CLI offers the tf-log flag. You can set it to any of Terraform's log levels:

-
    -
  • JSON (JSON-formatted logs at TRACE level)
    • -
  • TRACE
    • -
  • DEBUG
    • -
  • INFO
    • -
  • WARN
    • -
  • ERROR
    • -
-

The log output is written to the terraform.log file in the workspace directory. The output is appended to the file on each run.

If you want to use cert-manager with Constellation, pay attention to the following to avoid potential pitfalls.

-

Constellation ships with cert-manager preinstalled. -The default installation is part of the kube-system namespace, as all other Constellation-managed microservices. -You are free to install more instances of cert-manager into other namespaces. -However, be aware that any new installation needs to use the same version as the one installed with Constellation or rely on the same CRD versions. -Also remember to set the installCRDs value to false when installing new cert-manager instances. -It will create problems if you have two installations of cert-manager depending on different versions of the installed CRDs. -CRDs are cluster-wide resources and cert-manager depends on specific versions of those CRDs for each release.

Configure your cluster

-
info

This recording presents the essence of this page. It's recommended to read it in full for the motivation and all details.

-
Loading asciinema cast...
-
-

Before you can create your cluster, you need to configure the identity and access management (IAM) for your cloud service provider (CSP) and choose machine types for the nodes.

-

Creating the configuration file​

-

You can generate a configuration file for your CSP by using the following CLI command:

-
constellation config generate aws
-

This creates the file constellation-conf.yaml in the current directory.

-

Choosing a VM type​

-

Constellation supports the following VM types:

-

By default, Constellation uses m6a.xlarge VMs (4 vCPUs, 16 GB RAM) to create your cluster. -Optionally, you can switch to a different VM type by modifying instanceType in the configuration file. -If you are using the default attestation variant awsSEVSNP, you can use the instance types described in AWS's AMD SEV-SNP docs. -Please mind the region restrictions mentioned in the Getting started section.

If you are using the attestation variant awsNitroTPM, you can choose any of the nitroTPM-enabled instance types.

The Constellation CLI can also print the supported instance types with: constellation config instance-types.

-

Fill the desired VM type into the instanceType fields in the constellation-conf.yml file.

-

Creating additional node groups​

-

By default, Constellation creates the node groups control_plane_default and worker_default for control-plane nodes and workers, respectively. -If you require additional control-plane or worker groups with different instance types, zone placements, or disk sizes, you can add additional node groups to the constellation-conf.yml file. -Each node group can be scaled individually.

-

Consider the following example for AWS:

-
nodeGroups:
  control_plane_default:
    role: control-plane
    instanceType: c6a.xlarge
    stateDiskSizeGB: 30
    stateDiskType: gp3
    zone: eu-west-1c
    initialCount: 3
  worker_default:
    role: worker
    instanceType: c6a.xlarge
    stateDiskSizeGB: 30
    stateDiskType: gp3
    zone: eu-west-1c
    initialCount: 2
  high_cpu:
    role: worker
    instanceType: c6a.24xlarge
    stateDiskSizeGB: 128
    stateDiskType: gp3
    zone: eu-west-1c
    initialCount: 1
-

This configuration creates an additional node group high_cpu with a larger instance type and disk.

-

You can use the field zone to specify what availability zone nodes of the group are placed in. -On Azure, this field is empty by default and nodes are automatically spread across availability zones. -STACKIT currently offers SEV-enabled CPUs in the eu01-1, eu01-2, and eu01-3 zones. -Consult the documentation of your cloud provider for more information:

- -

Choosing a Kubernetes version​

-

To learn which Kubernetes versions can be installed with your current CLI, you can run constellation config kubernetes-versions. -See also Constellation's Kubernetes support policy.

-

Creating an IAM configuration​

-

You can create an IAM configuration for your cluster automatically using the constellation iam create command. -If you already have a Constellation configuration file, you can add the --update-config flag to the command. This writes the needed IAM fields into your configuration. Furthermore, the flag updates the zone/region of the configuration if it hasn't been set yet.

-

You must be authenticated with the AWS CLI in the shell session with a user that has the required permissions for IAM creation.

constellation iam create aws --zone=us-east-2a --prefix=constellTest

This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created.

Constellation OS images are currently replicated to the following regions:

    -
  • eu-central-1
    • -
  • eu-west-1
    • -
  • eu-west-3
    • -
  • us-east-2
    • -
  • ap-south-1
    • -

If you require the OS image to be available in another region, let us know.

You can find a list of all regions in AWS's documentation.

Paste the output into the corresponding fields of the constellation-conf.yaml file.

-
Alternatively, you can manually create the IAM configuration on your CSP.

The following describes the configuration fields and how you obtain the required information or create the required resources.

    -
  • -

    region: The name of your chosen AWS data center region, e.g., us-east-2.

    -

    Constellation OS images are currently replicated to the following regions:

    -
      -
    • eu-central-1
      • -
    • eu-west-1
      • -
    • eu-west-3
      • -
    • us-east-2
      • -
    • ap-south-1
      • -
    -

    If you require the OS image to be available in another region, let us know.

    -

    You can find a list of all regions in AWS's documentation.

    -
    • -
  • -

    zone: The name of your chosen AWS data center availability zone, e.g., us-east-2a.

    -

    Learn more about availability zones in AWS's documentation.

    -
    • -
  • -

    iamProfileControlPlane: The name of an IAM instance profile attached to all control-plane nodes.

    -

    You can create the resource with Terraform. For that, use the provided Terraform script to generate the necessary profile. The profile name will be provided as Terraform output value: control_plane_instance_profile_name.

    -

    Alternatively, you can create the AWS profile with a tool of your choice. Use the JSON policy in main.tf in the resource aws_iam_policy.control_plane_policy.

    -
    • -
  • -

    iamProfileWorkerNodes: The name of an IAM instance profile attached to all worker nodes.

    -

    You can create the resource with Terraform. For that, use the provided Terraform script to generate the necessary profile. The profile name will be provided as Terraform output value: worker_nodes_instance_profile_name.

    -

    Alternatively, you can create the AWS profile with a tool of your choice. Use the JSON policy in main.tf in the resource aws_iam_policy.worker_node_policy.

    -
    • -
-

Now that you've configured your CSP, you can create your cluster.

-

Deleting an IAM configuration​

-

You can keep a created IAM configuration and reuse it for new clusters. Alternatively, you can also delete it if you don't want to use it anymore.

-

Delete the IAM configuration by executing the following command in the same directory where you executed constellation iam create (the directory that contains constellation-iam-terraform as a subdirectory):

-
constellation iam destroy
-
caution

For Azure, deleting the IAM configuration by executing constellation iam destroy will delete the whole resource group created by constellation iam create. -This also includes any additional resources in the resource group that weren't created by Constellation.

-

Creating your cluster happens through multiple phases. -The most significant ones are:

-
    -
  1. Creating the necessary resources in your cloud environment
    2. -
  2. Bootstrapping the Constellation cluster and setting up a connection
    3. -
  3. Installing the necessary Kubernetes components
    4. -
-

constellation apply handles all this in a single command. -You can use the --skip-phases flag to skip specific phases of the process. -For example, if you created the infrastructure manually, you can skip the cloud resource creation phase.

-

See the architecture section for details on the inner workings of this process.

-
tip

If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

-

Before you create the cluster, make sure to have a valid configuration file.

-
constellation apply

apply stores the state of your cluster's cloud resources in a constellation-terraform directory in your workspace.

-

Finally, configure kubectl for your cluster:

-
export KUBECONFIG="$PWD/constellation-admin.conf"
-

🏁 That's it. You've successfully created a Constellation cluster.

-

Troubleshooting​

-

In case apply fails, the CLI collects logs from the bootstrapping instance and stores them inside constellation-cluster.log.

Expose a service

-

Constellation integrates the native load balancers of each CSP. Therefore, to expose a service simply create a service of type LoadBalancer.

-

Internet-facing LB service on AWS​

-

To expose your application service externally you might want to use a Kubernetes Service of type LoadBalancer. On AWS, load-balancing is achieved through the AWS Load Balancer Controller as in the managed EKS.

-

Since recent versions, the controller deploy an internal LB by default requiring to set an annotation service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing to have an internet-facing LB. For more details, see the official docs.

-

For general information on LB with AWS see Network load balancing on Amazon EKS.

-
caution

Before terminating the cluster, all LB backed services should be deleted, so that the controller can cleanup the related resources.

-

Ingress on AWS​

-

The AWS Load Balancer Controller also provisions Ingress resources of class alb. -AWS Application Load Balancers (ALBs) can be configured with a target-type. -The target type ip requires using the EKS container network solution, which makes it incompatible with Constellation. -If a service can be exposed on a NodePort, the target type instance can be used.

-

See Application load balancing on Amazon EKS for more information.

-
caution

Ingress handlers backed by AWS ALBs reside outside the Constellation cluster, so they shouldn't be handling sensitive traffic!

Recover your cluster

-

Recovery of a Constellation cluster means getting it back into a healthy state after too many concurrent node failures in the control plane. -Reasons for an unhealthy cluster can vary from a power outage, or planned reboot, to migration of nodes and regions. -Recovery events are rare, because Constellation is built for high availability and automatically and securely replaces failed nodes. When a node is replaced, Constellation's control plane first verifies the new node before it sends the node the cryptographic keys required to decrypt its state disk.

-

Constellation provides a recovery mechanism for cases where the control plane has failed and is unable to replace nodes. -The constellation recover command securely connects to all nodes in need of recovery using attested TLS and provides them with the keys to decrypt their state disks and continue booting.

-

Identify unhealthy clusters​

-

The first step to recovery is identifying when a cluster becomes unhealthy. -Usually, this can be first observed when the Kubernetes API server becomes unresponsive.

-

You can check the health status of the nodes via the cloud service provider (CSP). -Constellation provides logging information on the boot process and status via serial console output. -In the following, you'll find detailed descriptions for identifying clusters stuck in recovery for each CSP.

-

First, open the AWS console to view all Auto Scaling Groups (ASGs) in the region of your cluster. Select the ASG of the control plane <cluster-name>-<UID>-control-plane and check that enough members are in a Running state.

Second, check the boot logs of these Instances. In the ASG's Instance management view, select each desired instance. In the upper right corner, select Action > Monitor and troubleshoot > Get system log.

In the serial console output, search for Waiting for decryption key. -Similar output to the following means your node was restarted and needs to decrypt the state disk:

{"level":"INFO","ts":"2022-09-08T10:21:53Z","caller":"cmd/main.go:55","msg":"Starting disk-mapper","version":"2.0.0","cloudProvider":"gcp"}
{"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"setupManager","caller":"setup/setup.go:72","msg":"Preparing existing state disk"}

{"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"recoveryServer","caller":"recoveryserver/server.go:59","msg":"Starting RecoveryServer"}

The node will then try to connect to the JoinService and obtain the decryption key. -If this fails due to an unhealthy control plane, you will see log messages similar to the following:

{"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"rejoinClient","caller":"rejoinclient/client.go:77","msg":"Received list with JoinService endpoints","endpoints":["192.168.178.4:30090","192.168.178.2:30090"]}

This means that you have to recover the node manually.

-

Recover a cluster​

-

Recovering a cluster requires the following parameters:

-
    -
  • The constellation-state.yaml file in your working directory or the cluster's endpoint
    • -
  • The master secret of the cluster
    • -
-

A cluster can be recovered like this:

-
$ constellation recover
Pushed recovery key.

Reproduce released artifacts

-

Constellation has first-class support for reproducible builds. -Reproducing the released artifacts is an alternative to signature verification that doesn't require trusting Edgeless Systems' release process. -The following sections describe how to rebuild an artifact and how Constellation ensures that the rebuild reproduces the artifacts bit-by-bit.

-

Build environment prerequisites​

-

The build systems used by Constellation - Bazel and Nix - are designed for deterministic, reproducible builds. -These two dependencies should be the only prerequisites for a successful build. -However, it can't be ruled out completely that peculiarities of the host affect the build result. -Thus, we recommend the following host setup for best results:

-
    -
  1. A Linux operating system not older than v5.4.
    2. -
  2. The GNU C library not older than v2.31 (avoid musl).
    3. -
  3. GNU coreutils not older than v8.30 (avoid busybox).
    4. -
  4. An ext4 filesystem for building.
    5. -
  5. AppArmor turned off.
    6. -
-

This is given, for example, on an Ubuntu 22.04 system, which is also used for reproducibility tests.

-
note

To avoid any backwards-compatibility issues, the host software versions should also not be much newer than the Constellation release.

-

Run the build​

-

The following instructions outline qualitatively how to reproduce a build. -Constellation implements these instructions in the Reproducible Builds workflow, which continuously tests for reproducibility. -The workflow is a good place to look up specific version numbers and build steps.

-
    -
  1. -

    Check out the Constellation repository at the tag corresponding to the release.

    -
    git clone https://github.com/edgelesssys/constellation.git
    cd constellation
    git checkout v2.20.0
    -
    2. -
  2. -

    Install the Bazel release specified in .bazelversion.

    -
    3. -
  3. -

    Install Nix (any recent version should do).

    -
    4. -
  4. -

    Run the build with bazel build $target for one of the following targets of interest:

    -
    //cli:cli_enterprise_darwin_amd64
    //cli:cli_enterprise_darwin_arm64
    //cli:cli_enterprise_linux_amd64
    //cli:cli_enterprise_linux_arm64
    //cli:cli_enterprise_windows_amd64
    -
    5. -
  5. -

    Compare the build result with the downloaded release artifact.

    -
    6. -
-

Feedback​

-

Reproduction failures often indicate a bug in the build system or in the build definitions. -Therefore, we're interested in any reproducibility issues you might encounter. -Start a bug report and describe the details of your build environment. -Make sure to include your result binary or a diffoscope report, if possible.

Install s3proxy

-

Constellation includes a transparent client-side encryption proxy for AWS S3 and compatible stores. -s3proxy encrypts objects before sending them to S3 and automatically decrypts them on retrieval, without requiring changes to your application. -With s3proxy, you can use S3 for storage in a confidential way without having to trust the storage provider.

-

Limitations​

-

Currently, s3proxy has the following limitations:

-
    -
  • Only PutObject and GetObject requests are encrypted/decrypted by s3proxy. -By default, s3proxy will block requests that may expose unencrypted data to S3 (e.g. UploadPart). -The allow-multipart flag disables request blocking for evaluation purposes.
    • -
  • Using the Range header on GetObject is currently not supported and will result in an error.
    • -
-

These limitations will be removed with future iterations of s3proxy. -If you want to use s3proxy but these limitations stop you from doing so, consider opening an issue.

-

Deployment​

-

You can add the s3proxy to your Constellation cluster as follows:

-
    -
  1. Add the Edgeless Systems chart repository: -
    helm repo add edgeless https://helm.edgeless.systems/stable
    helm repo update
    -
    2. -
  2. Set ACCESS_KEY and ACCESS_SECRET to valid credentials you want s3proxy to use to interact with S3.
    3. -
  3. Deploy s3proxy: -
    helm install s3proxy edgeless/s3proxy --set awsAccessKeyID="$ACCESS_KEY" --set awsSecretAccessKey="$ACCESS_SECRET"
    -
    4. -
-

If you want to run a demo application, check out the Filestash with s3proxy example.

-

Technical details​

-

Encryption​

-

s3proxy relies on Google's Tink Cryptographic Library to implement cryptographic operations securely. -The used cryptographic primitives are NIST SP 800 38f for key wrapping and AES-GCM with 256 bit keys for data encryption.

-

s3proxy uses envelope encryption to encrypt objects. -This means s3proxy uses a key encryption key (KEK) issued by the KeyService to encrypt data encryption keys (DEKs). -Each S3 object is encrypted with its own DEK. -The encrypted DEK is then saved as metadata of the encrypted object. -This enables key rotation of the KEK without re-encrypting the data in S3. -The approach also allows access to objects from different locations, as long as each location has access to the KEK.

-

Traffic interception​

-

To use s3proxy, you have to redirect your outbound S3 traffic to s3proxy. -This can either be done by modifying your client application or by changing the deployment of your application.

-

The necessary deployment modifications are to add DNS redirection and a trusted TLS certificate to the client's trust store. -DNS redirection can be defined for each pod, allowing you to use s3proxy for one application without changing other applications in the same cluster. -Adding a trusted TLS certificate is necessary as clients communicate with s3proxy via HTTPS. -To have your client application trust s3proxy's TLS certificate, the certificate has to be added to the client's certificate trust store. -The Filestash with s3proxy example shows how to do this.

Consume software bill of materials (SBOMs)

-

-
-

Constellation builds produce a software bill of materials (SBOM) for each generated artifact. -You can use SBOMs to make informed decisions about dependencies and vulnerabilities in a given application. Enterprises rely on SBOMs to maintain an inventory of used applications, which allows them to take data-driven approaches to managing risks related to vulnerabilities.

-

SBOMs for Constellation are generated using Syft, signed using Cosign, and stored with the produced artifact.

-
note

The public key for Edgeless Systems' long-term code-signing key is:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEf8F1hpmwE+YCFXzjGtaQcrL6XZVT
JmEe5iSLvG1SyQSAew7WdMKF6o9t8e2TFuCkzlOhhlws2OHWbiFZnFWCFw==
-----END PUBLIC KEY-----

The public key is also available for download at https://edgeless.systems/es.pub and in the Twitter profile @EdgelessSystems.

Make sure the key is available in a file named cosign.pub to execute the following examples.

-

Verify and download SBOMs​

-

The following sections detail how to work with each type of artifact to verify and extract the SBOM.

-

Constellation CLI​

-

The SBOM for Constellation CLI is made available on the GitHub release page. The SBOM (constellation.spdx.sbom) and corresponding signature (constellation.spdx.sbom.sig) are valid for each Constellation CLI for a given version, regardless of architecture and operating system.

-
curl -LO https://github.com/edgelesssys/constellation/releases/download/v2.2.0/constellation.spdx.sbom
curl -LO https://github.com/edgelesssys/constellation/releases/download/v2.2.0/constellation.spdx.sbom.sig
cosign verify-blob --key cosign.pub --signature constellation.spdx.sbom.sig constellation.spdx.sbom
-

Container Images​

-

SBOMs for container images are attached to the image using Cosign and uploaded to the same registry.

-

As a consumer, use cosign to download and verify the SBOM:

-
# Verify and download the attestation statement
cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.att.json
# Extract SBOM from attestation statement
jq -r .payload verification-service.att.json | base64 -d > verification-service.cyclonedx.sbom
-

A successful verification should result in similar output:

-
$ cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.sbom

Verification for ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --
The following checks were performed on each of these signatures:
  - The cosign claims were validated
  - The signatures were verified against the specified public key
$ jq -r .payload verification-service.sbom | base64 -d > verification-service.cyclonedx.sbom
-
note

This example considers only the verification-service. The same approach works for all containers in the Constellation container registry.

-

Vulnerability scanning​

-

You can use a plethora of tools to consume SBOMs. This section provides suggestions for tools that are popular and known to produce reliable results, but any tool that consumes SPDX or CycloneDX files should work.

-

Syft is able to convert between the two formats in case you require a specific type.

-

Grype​

-

Grype is a CLI tool that lends itself well for integration into CI/CD systems or local developer machines. It's also able to consume the signed attestation statement directly and does the verification in one go.

-
grype att:verification-service.sbom --key cosign.pub --add-cpes-if-none -q
-

Dependency Track​

-

Dependency Track is one of the oldest and most mature solutions when it comes to managing software inventory and vulnerabilities. Once imported, it continuously scans SBOMs for new vulnerabilities. It supports the CycloneDX format and provides direct guidance on how to comply with U.S. Executive Order 14028.

Version: 2.22

Scale your cluster

-

Constellation provides all features of a Kubernetes cluster including scaling and autoscaling.

-

Worker node scaling​

-

Autoscaling​

-

Constellation comes with autoscaling disabled by default. To enable autoscaling, find the scaling group of -worker nodes:

-
kubectl get scalinggroups -o json | yq '.items | .[] | select(.spec.role == "Worker") | [{"name": .metadata.name, "nodeGoupName": .spec.nodeGroupName}]'
-

This will output a list of scaling groups with the corresponding cloud provider name (name) and the cloud provider agnostic name of the node group (nodeGroupName).

-

Then, patch the autoscaling field of the scaling group resource with the desired name to true:

-
# Replace <name> with the name of the scaling group you want to enable autoscaling for
worker_group=<name>
kubectl patch scalinggroups $worker_group --patch '{"spec":{"autoscaling": true}}' --type='merge'
kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
-

The cluster autoscaler now automatically provisions additional worker nodes so that all pods have a place to run. -You can configure the minimum and maximum number of worker nodes in the scaling group by patching the min or -max fields of the scaling group resource:

-
kubectl patch scalinggroups $worker_group --patch '{"spec":{"max": 5}}' --type='merge'
kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
-

The cluster autoscaler will now never provision more than 5 worker nodes.

-

If you want to see the autoscaling in action, try to add a deployment with a lot of replicas, like the -following Nginx deployment. The number of replicas needed to trigger the autoscaling depends on the size of -and count of your worker nodes. Wait for the rollout of the deployment to finish and compare the number of -worker nodes before and after the deployment:

-
kubectl create deployment nginx --image=nginx --replicas 150
kubectl -n kube-system get nodes
kubectl rollout status deployment nginx
kubectl -n kube-system get nodes
-

Manual scaling​

-

Alternatively, you can manually scale your cluster up or down:

-
    -
  1. Go to Auto Scaling Groups and select the worker ASG to scale up.
    2. -
  2. Click Edit
    3. -
  3. Set the new (increased) Desired capacity and Update.
    4. -
-

Control-plane node scaling​

-

Control-plane nodes can only be scaled manually and only scaled up!

-

To increase the number of control-plane nodes, follow these steps:

-
    -
  1. Go to Auto Scaling Groups and select the control-plane ASG to scale up.
    2. -
  2. Click Edit
    3. -
  3. Set the new (increased) Desired capacity and Update.
    4. -
-

If you scale down the number of control-planes nodes, the removed nodes won't be able to exit the etcd cluster correctly. This will endanger the quorum that's required to run a stable Kubernetes control plane.

Use persistent storage

-

Persistent storage in Kubernetes requires cloud-specific configuration. -For abstraction of container storage, Kubernetes offers volumes, -allowing users to mount storage solutions directly into containers. -The Container Storage Interface (CSI) is the standard interface for exposing arbitrary block and file storage systems into containers in Kubernetes. -Cloud service providers (CSPs) offer their own CSI-based solutions for cloud storage.

-

Confidential storage​

-

Most cloud storage solutions support encryption, such as GCE Persistent Disks (PD). -Constellation supports the available CSI-based storage options for Kubernetes engines in AWS, Azure, GCP, and STACKIT. -However, their encryption takes place in the storage backend and is managed by the CSP. -Thus, using the default CSI drivers for these storage types means trusting the CSP with your persistent data.

-

To address this, Constellation provides CSI drivers for AWS EBS, Azure Disk, GCE PD, and OpenStack Cinder, offering encryption on the node level. They enable transparent encryption for persistent volumes without needing to trust the cloud backend. Plaintext data never leaves the confidential VM context, offering you confidential storage.

-

For more details see encrypted persistent storage.

-

CSI drivers​

-

Constellation supports the following drivers, which offer node-level encryption and optional integrity protection.

-

Constellation CSI driver for AWS Elastic Block Store -Mount Elastic Block Store storage volumes into your Constellation cluster. -Follow the instructions on how to install the Constellation CSI driver or check out the repository for more information.

-

Note that in case the options above aren't a suitable solution for you, Constellation is compatible with all other CSI-based storage options. For example, you can use AWS EFS, Azure Files, or GCP Filestore with Constellation out of the box. Constellation is just not providing transparent encryption on the node level for these storage types yet.

-

Installation​

-

The Constellation CLI automatically installs Constellation's CSI driver for the selected CSP in your cluster. -If you don't need a CSI driver or wish to deploy your own, you can disable the automatic installation by setting deployCSIDriver to false in your Constellation config file.

-

AWS comes with two storage classes by default.

    -
  • encrypted-rwo -
      -
    • Uses SSDs of gp3 type
      • -
    • ext-4 filesystem
      • -

For more information on encryption algorithms and key sizes, refer to cryptographic algorithms.

info

The default storage class is set to encrypted-rwo for performance reasons. -If you want integrity-protected storage, set the storageClassName parameter of your persistent volume claim to integrity-encrypted-rwo.

Alternatively, you can create your own storage class with integrity protection enabled by adding csi.storage.k8s.io/fstype: ext4-integrity to the class parameters. -Or use another filesystem by specifying another file system type with the suffix -integrity, e.g., csi.storage.k8s.io/fstype: xfs-integrity.

Note that volume expansion isn't supported for integrity-protected disks.

-
    -
  1. -

    Create a persistent volume

    -

    A persistent volume claim is a request for storage with certain properties. -It can refer to a storage class. -The following creates a persistent volume claim, requesting 20 GB of storage via the encrypted-rwo storage class:

    -
    cat <<EOF | kubectl apply -f -
    kind: PersistentVolumeClaim
    apiVersion: v1
    metadata:
      name: pvc-example
      namespace: default
    spec:
      accessModes:
      - ReadWriteOnce
      storageClassName: encrypted-rwo
      resources:
        requests:
          storage: 20Gi
    EOF
    -
    2. -
  2. -

    Create a Pod with persistent storage

    -

    You can assign a persistent volume claim to an application in need of persistent storage. -The mounted volume will persist restarts. -The following creates a pod that uses the previously created persistent volume claim:

    -
    cat <<EOF | kubectl apply -f -
    apiVersion: v1
    kind: Pod
    metadata:
      name: web-server

        - mountPath: /var/lib/www/html
          name: mypvc
      volumes:
      - name: mypvc
        persistentVolumeClaim:
          claimName: pvc-example
          readOnly: false
    EOF
    -
    3. -
-

Change the default storage class​

-

The default storage class is responsible for all persistent volume claims that don't explicitly request storageClassName. -Constellation creates a storage class with encryption enabled and sets this as the default class. -In case you wish to change it, follow the steps below:

-
    -
  1. -

    List the storage classes in your cluster:

    -
    kubectl get storageclass
    -

    The output is similar to this:

    -
    NAME                      PROVISIONER                         RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
    encrypted-rwo (default)   {your-csp}.csi.confidential.cloud   Delete          Immediate           true                   1d
    integrity-encrypted-rwo   {your-csp}.csi.confidential.cloud   Delete          Immediate           false                  1d
    -

    The default storage class is marked by (default).

    -
    2. -
  2. -

    Mark old default storage class as non default

    -

    If you previously used another storage class as the default, you will have to remove that annotation:

    -
    kubectl patch storageclass encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
    -
    3. -
  3. -

    Mark new class as the default

    -
    kubectl patch storageclass integrity-encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
    -
    4. -
  4. -

    Verify that your chosen storage class is default:

    -
    kubectl get storageclass
    -

    The output is similar to this:

    -

You can terminate your cluster using the CLI. For this, you need the Terraform state directory named constellation-terraform in the current directory.

-
danger

All ephemeral storage and state of your cluster will be lost. Make sure any data is safely stored in persistent storage. Constellation can recreate your cluster and the associated encryption keys, but won't backup your application data automatically.

-

Terminate the cluster by running:

constellation terminate

Or without confirmation (e.g., for automation purposes):

constellation terminate --yes

This deletes all resources created by Constellation in your cloud environment. -All local files created by the apply command are deleted as well, except for constellation-mastersecret.json and the configuration file.

caution

Termination can fail if additional resources have been created that depend on the ones managed by Constellation. In this case, you need to delete these additional -resources manually. Just run the terminate command again afterward to continue the termination process of the cluster.

This example shows how to set up a Constellation cluster with the reference IAM and infrastructure setup. This setup is also used when creating a Constellation cluster through the Constellation CLI. You can either consume the IAM / infrastructure modules through a remote source (recommended) or local files. The latter requires downloading the infrastructure and IAM modules for the corresponding CSP from terraform-modules.zip on the Constellation release page and placing them in the Terraform workspace directory.

-
    -
  1. Create a directory (workspace) for your Constellation cluster.
    2. -
-
mkdir constellation-workspace
cd constellation-workspace
-
    -
  1. Use one of the example configurations for using the Constellation Terraform provider or create a main.tf file and fill it with the resources you want to create. The Constellation Terraform provider documentation offers thorough documentation on the resources and their attributes.

  2. Initialize and apply the Terraform configuration.
    3. -
-

Initialize the providers and apply the configuration.

terraform init
terraform apply

Optionally, you can prefix the terraform apply command with TF_LOG=INFO to collect Terraform logs while applying the configuration. This may provide helpful output in debugging scenarios.

    -
  1. Connect to the cluster.
    2. -
-
terraform output -raw kubeconfig > constellation-admin.conf
export KUBECONFIG=$(realpath constellation-admin.conf)
-

Bringing your own infrastructure​

-

Instead of using the example infrastructure used in the quick setup, you can also provide your own infrastructure. -If you need a starting point for a custom infrastructure setup, you can download the infrastructure / IAM Terraform modules for the respective CSP from the Constellation GitHub releases. You can modify and extend the modules per your requirements, while keeping the basic functionality intact. -The module contains:

-
    -
  • {csp}: cloud resources the cluster runs on
    • -
  • iam/{csp}: IAM resources used within the cluster
    • -
-

When upgrading your cluster, make sure to check the Constellation release notes for potential breaking changes in the reference infrastructure / IAM modules that need to be considered.

-

Cluster upgrades​

-
tip

Also see the general documentation on cluster upgrades.

-

The steps for applying the upgrade are as follows:

-
    -
  1. Update the version constraint of the Constellation Terraform provider in the required_providers block in your Terraform configuration.
    2. -
  2. If you explicitly set any of the version attributes of the provider's resources and data sources (e.g. image_version or constellation_microservice_version), make sure to update them too. Refer to Constellation's version support policy for more information on how each Constellation version and its dependencies are supported.
    3. -
  3. Update the IAM / infrastructure configuration. - -
    4. -
  4. Upgrade the Terraform module and provider dependencies and apply the targeted configuration.
    5. -
-
  terraform init -upgrade
  terraform apply

Troubleshooting

-

This section aids you in finding problems when working with Constellation.

-

Common issues​

-

Issues with creating new clusters​

-

When you create a new cluster, you should always use the latest release. -If something doesn't work, check out the known issues.

-

Azure: Resource Providers can't be registered​

-

On Azure, you may receive the following error when running apply or terminate with limited IAM permissions:

-
Error: Error ensuring Resource Providers are registered.

Terraform automatically attempts to register the Resource Providers it supports to
ensure it's able to provision resources.

If you don't have permission to register Resource Providers you may wish to use the
"skip_provider_registration" flag in the Provider block to disable this functionality.

[...]
-

To continue, please ensure that the required resource providers have been registered in your subscription by your administrator.

-

Afterward, set ARM_SKIP_PROVIDER_REGISTRATION=true as an environment variable and either run apply or terminate again. -For example:

-
ARM_SKIP_PROVIDER_REGISTRATION=true constellation apply
-

Or alternatively, for terminate:

-
ARM_SKIP_PROVIDER_REGISTRATION=true constellation terminate
-

Azure: Can't update attestation policy​

-

On Azure, you may receive the following error when running apply from within an Azure environment, e.g., an Azure VM:

-
An error occurred: patching policies: updating attestation policy: unexpected status code: 403 Forbidden
-

The problem occurs because the Azure SDK we use internally attempts to authenticate towards the Azure API with the managed identity of your current environment instead of the Azure CLI token.

-

We decided not to deviate from this behavior and comply with the ordering of credentials.

-

A solution is to add the required permissions to the managed identity of your environment. For example, the managed identity of your Azure VM, instead of the account that you've authenticated with in the Azure CLI.

-

If your setup requires a change in the ordering of credentials, please open an issue and explain your desired behavior.

-

Nodes fail to join with error untrusted measurement value​

-

This error indicates that a node's attestation statement contains measurements that don't match the trusted values expected by the JoinService. -This may for example happen if the cloud provider updates the VM's firmware such that it influences the runtime measurements in an unforeseen way. -A failed upgrade due to an erroneous attestation config can also cause this error. -You can change the expected measurements to resolve the failure.

-
caution

Attestation and trusted measurements are crucial for the security of your cluster. -Be extra careful when manually changing these settings. -When in doubt, check if the encountered issue is known or contact support.

-
tip

During an upgrade with modified attestation config, a backup of the current configuration is stored in the join-config config map in the kube-system namespace under the attestationConfig_backup key. To restore the old attestation config after a failed upgrade, replace the value of attestationConfig with the value from attestationConfig_backup:

kubectl patch configmaps -n kube-system join-config -p "{\"data\":{\"attestationConfig\":\"$(kubectl get configmaps -n kube-system join-config -o "jsonpath={.data.attestationConfig_backup}")\"}}"
-

You can use the apply command to change measurements of a running cluster:

-
    -
  1. Modify the measurements key in your local constellation-conf.yaml to the expected values.
    2. -
  2. Run constellation apply.
    3. -
-

Keep in mind that running apply also applies any version changes from your config to the cluster.

-

You can run these commands to learn about the versions currently configured in the cluster:

-
    -
  • Kubernetes API server version: kubectl get nodeversion constellation-version -o json -n kube-system | jq .spec.kubernetesClusterVersion
    • -
  • image version: kubectl get nodeversion constellation-version -o json -n kube-system | jq .spec.imageVersion
    • -
  • microservices versions: helm list --filter 'constellation-services' -n kube-system
    • -
-

Upgrading Kubernetes resources fails​

-

Constellation manages its Kubernetes resources using Helm. -When applying an upgrade, the charts that are about to be installed, and a values override file overrides.yaml, -are saved to disk in your current workspace under constellation-upgrade/upgrade-<timestamp>/helm-charts/. -If upgrading the charts using the Constellation CLI fails, you can review these charts and try to manually apply the upgrade.

-
caution

Changing and manually applying the charts may destroy cluster resources and can lead to broken Constellation deployments. -Proceed with caution and when in doubt, -check if the encountered issue is known or contact support.

-

Diagnosing issues​

-

Logs​

-

To get started on diagnosing issues with Constellation, it's often helpful to collect logs from nodes, pods, or other resources in the cluster. Most logs are available through Kubernetes' standard -logging interfaces.

-

To debug issues occurring at boot time of the nodes, you can use the serial console interface of the CSP while the machine boots to get a read-only view of the boot logs.

-

Apart from that, Constellation also offers further observability integrations.

-

Node shell access​

-

Debugging via a shell on a node is directly supported by Kubernetes.

-
    -
  1. -

    Figure out which node to connect to:

    -
    kubectl get nodes
    # or to see more information, such as IPs:
    kubectl get nodes -o wide
    -
    2. -
  2. -

    Connect to the node:

    -
    kubectl debug node/constell-worker-xksa0-000000 -it --image=busybox
    -

    You will be presented with a prompt.

    -

    The nodes file system is mounted at /host.

    -
    3. -
  3. -

    Once finished, clean up the debug pod:

    -
    kubectl delete pod node-debugger-constell-worker-xksa0-000000-bjthj
    -
    4. -
-

Emergency SSH access​

-

Emergency SSH access to nodes can be useful to diagnose issues or download important data even if the Kubernetes API isn't reachable anymore.

-
    -
  1. -

    Enter the constellation-terraform directory in your Constellation workspace and enable emergency SSH access to the cluster:

    -
     cd constellation-terraform
     echo "emergency_ssh = true" >> ./terraform.tfvars
     terraform apply
    -
    2. -
  2. -

    Sign an existing SSH key with your master secret:

    -
    cd ../ # go back to your Constellation workspace
    constellation ssh --key your_public_key.pub
    -

    A certificate is written to constellation_cert.pub.

    -

    The certificate is valid for 24 hours and enables you to access your Constellation nodes using -certificate based authentication.

    -
    3. -
  3. -

    Now you can connect to any Constellation node using your certificate and your private key.

    -
    ssh -o CertificateFile=constellation_cert.pub -i <your private key> root@<ip of constellation node>
    -

    Normally, you don't have access to the Constellation nodes since they reside in a private network. -To access those nodes anyways, you can use your Constellation load balancer as a proxy jump host. -For this, use something along the following SSH client configuration:

    -
    Host <LB domain name>
      ProxyJump none

    Host *
      IdentityFile <your private key>
      PreferredAuthentications publickey
      CertificateFile=constellation_cert.pub
      User root
      ProxyJump <LB domain name>
    -

    With this configuration you can connect to a Constellation node using ssh -F <this config> <private node IP>. -You can obtain the private node IP and the domain name of the load balancer using your CSP's web UI.

Version: 2.22

Use Azure trusted launch VMs

-

Constellation also supports trusted launch VMs on Microsoft Azure. Trusted launch VMs don't offer the same level of security as Confidential VMs, but are available in more regions and in larger quantities. The main difference between trusted launch VMs and normal VMs is that the former offer vTPM-based remote attestation. When used with trusted launch VMs, Constellation relies on vTPM-based remote attestation to verify nodes.

-
caution

Trusted launch VMs don't provide runtime encryption and don't keep the cloud service provider (CSP) out of your trusted computing base.

-

Constellation supports trusted launch VMs with instance types Standard_D*_v4 and Standard_E*_v4. Run constellation config instance-types for a list of all supported instance types.

-

VM images​

-

Azure currently doesn't support community galleries for trusted launch VMs. Thus, you need to manually import the Constellation node image into your cloud subscription.

-

The latest image is available at https://cdn.confidential.cloud/constellation/images/azure/trusted-launch/v2.2.0/constellation.img. Simply adjust the version number to download a newer version.

-

After you've downloaded the image, create a resource group constellation-images in your Azure subscription and import the image. -You can use a script to do this:

-
wget https://raw.githubusercontent.com/edgelesssys/constellation/main/hack/importAzure.sh
chmod +x importAzure.sh
AZURE_IMAGE_VERSION=2.2.0 AZURE_RESOURCE_GROUP_NAME=constellation-images AZURE_IMAGE_FILE=./constellation.img ./importAzure.sh
-

The script creates the following resources:

-
    -
  1. A new image gallery with the default name constellation-import
    2. -
  2. A new image definition with the default name constellation
    3. -
  3. The actual image with the provided version. In this case 2.2.0
    4. -
-

Once the import is completed, use the ID of the image version in your constellation-conf.yaml for the image field. Set confidentialVM to false.

-

Fetch the image measurements:

-
IMAGE_VERSION=2.2.0
URL=https://public-edgeless-constellation.s3.us-east-2.amazonaws.com//communitygalleries/constellationcvm-b3782fa0-0df7-4f2f-963e-fc7fc42663df/images/constellation/versions/$IMAGE_VERSION/measurements.yaml
constellation config fetch-measurements -u$URL -s$URL.sig
-
info

The constellation apply command will issue a warning because manually imported images aren't recognized as production grade images:

Configured image doesn't look like a released production image. Double check image before deploying to production.

Please ignore this warning.

Version: 2.22

Upgrade your cluster

-

Constellation provides an easy way to upgrade all components of your cluster, without disrupting its availability. -Specifically, you can upgrade the Kubernetes version, the nodes' image, and the Constellation microservices. -You configure the desired versions in your local Constellation configuration and trigger upgrades with the apply command. -To learn about available versions you use the upgrade check command. -Which versions are available depends on the CLI version you are using.

-

Update the CLI​

-

Each CLI comes with a set of supported microservice and Kubernetes versions. -Most importantly, a given CLI version can only upgrade a cluster of the previous minor version, but not older ones. -This means that you have to upgrade your CLI and cluster one minor version at a time.

-

For example, if you are currently on CLI version v2.6 and the latest version is v2.8, you should

-
    -
  • upgrade the CLI to v2.7,
    • -
  • upgrade the cluster to v2.7,
    • -
  • and only then continue upgrading the CLI (and the cluster) to v2.8 after.
    • -
-

Also note that if your current Kubernetes version isn't supported by the next CLI version, use your current CLI to upgrade to a newer Kubernetes version first.

-

To learn which Kubernetes versions are supported by a particular CLI, run constellation config kubernetes-versions.

-

Migrate the configuration​

-

The Constellation configuration file is located in the file constellation-conf.yaml in your workspace. -Refer to the migration reference to check if you need to update fields in your configuration file. -Use constellation config migrate to automatically update an old config file to a new format.

-

Check for upgrades​

-

To learn which versions the current CLI can upgrade to and what's installed in your cluster, run:

-
# Show possible upgrades
constellation upgrade check

# Show possible upgrades and write them to config file
constellation upgrade check --update-config
-

You can either enter the reported target versions into your config manually or run the above command with the --update-config flag. -When using this flag, the kubernetesVersion, image, microserviceVersion, and attestation fields are overwritten with the smallest available upgrade.

-

Apply the upgrade​

-

Once you updated your config with the desired versions, you can trigger the upgrade with this command:

-
constellation apply
-

Microservice upgrades will be finished within a few minutes, depending on the cluster size. -If you are interested, you can monitor pods restarting in the kube-system namespace with your tool of choice.

-

Image and Kubernetes upgrades take longer. -For each node in your cluster, a new node has to be created and joined. -The process usually takes up to ten minutes per node.

-

When applying an upgrade, the Helm charts for the upgrade as well as backup files of Constellation-managed Custom Resource Definitions, Custom Resources, and Terraform state are created. -You can use the Terraform state backup to restore previous resources in case an upgrade misconfigured or erroneously deleted a resource. -You can use the Custom Resource (Definition) backup files to restore Custom Resources and Definitions manually (e.g., via kubectl apply) if the automatic migration of those resources fails. -You can use the Helm charts to manually apply upgrades to the Kubernetes resources, should an upgrade fail.

-
note

For advanced users: the upgrade consists of several phases that can be individually skipped through the --skip-phases flag. -The phases are infrastracture for the cloud resource management through Terraform, helm for the chart management of the microservices, image for OS image upgrades, and k8s for Kubernetes version upgrades.

-

Check the status​

-

Upgrades are asynchronous operations. -After you run apply, it will take a while until the upgrade has completed. -To understand if an upgrade is finished, you can run:

-
constellation status
-

This command displays the following information:

-
    -
  • The installed services and their versions
    • -
  • The image and Kubernetes version the cluster is expecting on each node
    • -
  • How many nodes are up to date
    • -
-

Here's an example output:

-
Target versions:
    Image: v2.6.0
    Kubernetes: v1.25.8
Service versions:
    Cilium: v1.12.1
    cert-manager: v1.10.0
    constellation-operators: v2.6.0
    constellation-services: v2.6.0
Cluster status: Some node versions are out of date
    Image: 23/25
    Kubernetes: 25/25
-

This output indicates that the cluster is running Kubernetes version 1.25.8, and all nodes have the appropriate binaries installed. -23 out of 25 nodes have already upgraded to the targeted image version of 2.6.0, while two are still in progress.

-

Apply further upgrades​

-

After the upgrade is finished, you can run constellation upgrade check again to see if there are more upgrades available. If so, repeat the process.

Edgeless Systems uses sigstore and SLSA to ensure supply-chain security for the Constellation CLI and node images ("artifacts"). sigstore consists of three components: Cosign, Rekor, and Fulcio. Edgeless Systems uses Cosign to sign artifacts. All signatures are uploaded to the public Rekor transparency log, which resides at https://rekor.sigstore.dev.

-
note

The public key for Edgeless Systems' long-term code-signing key is:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEf8F1hpmwE+YCFXzjGtaQcrL6XZVT
JmEe5iSLvG1SyQSAew7WdMKF6o9t8e2TFuCkzlOhhlws2OHWbiFZnFWCFw==
-----END PUBLIC KEY-----

The public key is also available for download at https://edgeless.systems/es.pub and in the Twitter profile @EdgelessSystems.

-

The Rekor transparency log is a public append-only ledger that verifies and records signatures and associated metadata. The Rekor transparency log enables everyone to observe the sequence of (software) signatures issued by Edgeless Systems and many other parties. The transparency log allows for the public identification of dubious or malicious signatures.

-

You should always ensure that (1) your CLI executable was signed with the private key corresponding to the above public key and that (2) there is a corresponding entry in the Rekor transparency log. Both can be done as described in the following.

-
info

You don't need to verify the Constellation node images. This is done automatically by your CLI and the rest of Constellation.

-

Verify the signature​

-
info

This guide assumes Linux on an amd64 processor. The exact steps for other platforms differ slightly.

-

First, install the Cosign CLI. Next, download and verify the signature that accompanies your CLI executable, for example:

-
$ cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

Verified OK
-

The above performs an offline verification of the provided public key, signature, and executable. To also verify that a corresponding entry exists in the public Rekor transparency log, add the variable COSIGN_EXPERIMENTAL=1:

-
$ COSIGN_EXPERIMENTAL=1 cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

tlog entry verified with uuid: afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13 index: 3477047
Verified OK
-

🏁 You now know that your CLI executable was officially released and signed by Edgeless Systems.

-

Optional: Manually inspect the transparency log​

-

To further inspect the public Rekor transparency log, install the Rekor CLI. A search for the CLI executable should give a single UUID. (Note that this UUID contains the UUID from the previous cosign command.)

-
$ rekor-cli search --artifact constellation-linux-amd64

Found matching entries (listed by UUID):
362f8ecba72f4326afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13

-
rekor-cli search --public-key https://edgeless.systems/es.pub --pki-format x509
-

Edgeless Systems monitors this list to detect potential unauthorized use of its private key.

-

Verify the provenance​

-

Provenance attests that a software artifact was produced by a specific repository and build system invocation. For more information on provenance visit slsa.dev and learn about the adoption of SLSA for Constellation.

-

Just as checking its signature proves that the CLI hasn't been manipulated, checking the provenance proves that the artifact was produced by the expected build process and hasn't been tampered with.

-

To verify the provenance, first install the slsa-verifier. Then make sure you have the provenance file (constellation.intoto.jsonl) and Constellation CLI downloaded. Both are available on the GitHub release page.

-
info

The same provenance file is valid for all Constellation CLI executables of a given version independent of the target platform.

-

Use the verifier to perform the check:

-
$ slsa-verifier verify-artifact constellation-linux-amd64 \
  --provenance-path constellation.intoto.jsonl \
  --source-uri github.com/edgelesssys/constellation

Verify your cluster

-

Constellation's attestation feature allows you, or a third party, to verify the integrity and confidentiality of your Constellation cluster.

-

Fetch measurements​

-

To verify the integrity of Constellation you need trusted measurements to verify against. For each node image released by Edgeless Systems, there are signed measurements, which you can download using the CLI:

-
constellation config fetch-measurements
-

This command performs the following steps:

-
    -
  1. Download the signed measurements for the configured image. By default, this will use Edgeless Systems' public measurement registry.
    2. -
  2. Verify the signature of the measurements. This will use Edgeless Systems' public key.
    3. -
  3. Write measurements into configuration file.
    4. -
-

The configuration file then contains a list of measurements similar to the following:

-
# ...

-

Each entry specifies the expected value of the Constellation node, and whether the measurement should be enforced (warnOnly: false), or only a warning should be logged (warnOnly: true). -By default, the subset of the available measurements that can be locally reproduced and verified is enforced.

-

During attestation, the validating side (CLI or join service) compares each measurement reported by the issuing side (first node or joining node) individually. -For mismatching measurements that have set warnOnly to true only a warning is emitted. -For mismatching measurements that have set warnOnly to false an error is emitted and attestation fails. -If attestation fails for a new node, it isn't permitted to join the cluster.

-

The verify command​

-
note

The steps below are purely optional. They're automatically executed by constellation apply when you initialize your cluster. The constellation verify command mostly has an illustrative purpose.

-

The verify command obtains and verifies an attestation statement from a running Constellation cluster.

-
constellation verify [--cluster-id ...]
-

From the attestation statement, the command verifies the following properties:

-
    -
  • The cluster is using the correct Confidential VM (CVM) type.
    • -
  • Inside the CVMs, the correct node images are running. The node images are identified through the measurements obtained in the previous step.
    • -
  • The unique ID of the cluster matches the one from your constellation-state.yaml file or passed in via --cluster-id.
    • -
-

Once the above properties are verified, you know that you are talking to the right Constellation cluster and it's in a good and trustworthy shape.

-

Custom arguments​

-

The verify command also allows you to verify any Constellation deployment that you have network access to. For this you need the following:

-
    -
  • The IP address of a running Constellation cluster's VerificationService. The VerificationService is exposed via a NodePort service using the external IP address of your cluster. Run kubectl get nodes -o wide and look for EXTERNAL-IP.
    • -
  • The cluster's clusterID. See cluster identity for more details.
    • -
  • A constellation-conf.yaml file with the expected measurements of the cluster in your working directory.
    • -
-

Version: 2.23

Attestation

-

This page explains Constellation's attestation process and highlights the cornerstones of its trust model.

-

Terms​

-

The following lists terms and concepts that help to understand the attestation concept of Constellation.

-

Trusted Platform Module (TPM)​

-

A TPM chip is a dedicated tamper-resistant crypto-processor. -It can securely store artifacts such as passwords, certificates, encryption keys, or runtime measurements (more on this below). -When a TPM is implemented in software, it's typically called a virtual TPM (vTPM).

-

Runtime measurement​

-

A runtime measurement is a cryptographic hash of the memory pages of a so called runtime component. Runtime components of interest typically include a system's bootloader or OS kernel.

-

Platform Configuration Register (PCR)​

-

A Platform Configuration Register (PCR) is a memory location in the TPM that has some unique properties. -To store a new value in a PCR, the existing value is extended with a new value as follows:

-
PCR[N] = HASHalg( PCR[N] || ArgumentOfExtend )
-

The PCRs are typically used to store runtime measurements. -The new value of a PCR is always an extension of the existing value. -Thus, storing the measurements of multiple components into the same PCR irreversibly links them together.

-

Measured boot​

-

Measured boot builds on the concept of chained runtime measurements. -Each component in the boot chain loads and measures the next component into the PCR before executing it. -By comparing the resulting PCR values against trusted reference values, the integrity of the entire boot chain and thereby the running system can be ensured.

-

Remote attestation (RA)​

-

Remote attestation is the process of verifying certain properties of an application or platform, such as integrity and confidentiality, from a remote location. -In the case of a measured boot, the goal is to obtain a signed attestation statement on the PCR values of the boot measurements. -The statement can then be verified and compared to a set of trusted reference values. -This way, the integrity of the platform can be ensured before sharing secrets with it.

-

Confidential virtual machine (CVM)​

-

Confidential computing (CC) is the protection of data in-use with hardware-based trusted execution environments (TEEs). -With CVMs, TEEs encapsulate entire virtual machines and isolate them against the hypervisor, other VMs, and direct memory access. -After loading the initial VM image into encrypted memory, the hypervisor calls for a secure processor to measure these initial memory pages. -The secure processor locks these pages and generates an attestation report on the initial page measurements. -CVM memory pages are encrypted with a key that resides inside the secure processor, which makes sure only the guest VM can access them. -The attestation report is signed by the secure processor and can be verified using remote attestation via the certificate authority of the hardware vendor. -Such an attestation statement guarantees the confidentiality and integrity of a CVM.

-

Attested TLS (aTLS)​

-

In a CC environment, attested TLS (aTLS) can be used to establish secure connections between two parties using the remote attestation features of the CC components.

-

aTLS modifies the TLS handshake by embedding an attestation statement into the TLS certificate. -Instead of relying on a certificate authority, aTLS uses this attestation statement to establish trust in the certificate.

-

The protocol can be used by clients to verify a server certificate, by a server to verify a client certificate, or for mutual verification (mutual aTLS).

-

Overview​

-

The challenge for Constellation is to lift a CVM's attestation statement to the Kubernetes software layer and make it end-to-end verifiable. -From there, Constellation needs to expand the attestation from a single CVM to the entire cluster.

-

The JoinService and VerificationService are where all runs together. -Internally, the JoinService uses remote attestation to securely join CVM nodes to the cluster. -Externally, the VerificationService provides an attestation statement for the cluster's CVMs and configuration.

-

The following explains the details of both steps.

-

Node attestation​

-

The idea is that Constellation nodes should have verifiable integrity from the CVM hardware measurement up to the Kubernetes software layer. -The solution is a verifiable boot chain and an integrity-protected runtime environment.

-

Constellation uses measured boot within CVMs, measuring each component in the boot process before executing it. -Outside of CC, this is usually implemented via TPMs. -CVM technologies differ in how they implement runtime measurements, but the general concepts are similar to those of a TPM. -For simplicity, TPM terminology like PCR is used in the following.

-

When a Constellation node image boots inside a CVM, measured boot is used for all stages and components of the boot chain. -This process goes up to the root filesystem. -The root filesystem is mounted read-only with integrity protection. -For the details on the image and boot stages see the image architecture documentation. -Any changes to the image will inevitably also change the corresponding PCR values. -To create a node attestation statement, the Constellation image obtains a CVM attestation statement from the hardware. -This includes the runtime measurements and thereby binds the measured boot results to the CVM hardware measurement.

-

In addition to the image measurements, Constellation extends a PCR during the initialization phase that irrevocably marks the node as initialized. -The measurement is created using the clusterID, tying all future attestation statements to this ID. -Thereby, an attestation statement is unique for every cluster and a node can be identified unambiguously as being initialized.

-

To verify an attestation, the hardware's signature and a statement are verified first to establish trust in the contained runtime measurements. -If successful, the measurements are verified against the trusted values of the particular Constellation release version. -Finally, the measurement of the clusterID can be compared by calculating it with the master secret.

-

Runtime measurements​

-

Constellation uses runtime measurements to implement the measured boot approach. -As stated above, the underlying hardware technology and guest firmware differ in their implementations of runtime measurements. -The following gives a detailed description of the available measurements in the different cloud environments.

-

The runtime measurements consist of two types of values:

-
    -
  • -

    Measurements produced by the cloud infrastructure and firmware of the CVM: -These are measurements of closed-source firmware and other values controlled by the cloud provider. -While not being reproducible for the user, some of them can be compared against previously observed values. -Others may change frequently and aren't suitable for verification. -The signed image measurements include measurements that are known, previously observed values.

    -
    • -
  • -

    Measurements produced by the Constellation bootloader and boot chain: -The Constellation Bootloader takes over from the CVM firmware and measures the rest of the boot chain. -The Constellation Bootstrapper is the first user mode component that runs in a Constellation image. -It extends PCR registers with the IDs of the cluster marking a node as initialized.

    -
    • -
-

Constellation allows to specify in the config which measurements should be enforced during the attestation process. -Enforcing non-reproducible measurements controlled by the cloud provider means that changes in these values require manual updates to the cluster's config. -By default, Constellation only enforces measurements that are stable values produced by the infrastructure or by Constellation directly.

-

Constellation uses the vTPM (NitroTPM) feature of the AWS Nitro System on AWS for runtime measurements.

The vTPM adheres to the TPM 2.0 specification. -The VMs are attested by obtaining signed PCR values over the VM's boot configuration from the TPM and comparing them to a known, good state (measured boot).

The following table lists all PCR values of the vTPM and the measured components. -It also lists what components of the boot chain did the measurements and if the value is reproducible and verifiable. -The latter means that the value can be generated offline and compared to the one in the vTPM.

-

CVM verification​

-

To verify the integrity of the received attestation statement, a chain of trust from the CVM technology to the interface providing the statement has to be established. -For verification of the CVM technology, Constellation may expose additional options in its config file.

-

On AWS, AMD SEV-SNP is used to provide runtime encryption to the VMs. -An SEV-SNP attestation report is used to establish trust in the VM. -You may customize certain parameters for verification of the attestation statement using the Constellation config file.

    -
  • -

    TCB versions

    -

    You can set the minimum version numbers of components in the SEV-SNP TCB. -Use the latest versions to enforce that only machines with the most recent firmware updates are allowed to join the cluster. -Alternatively, you can set a lower minimum version to allow slightly out-of-date machines to still be able to join the cluster.

    -
    • -
  • -

    AMD Root Key Certificate

    -

    This certificate is the root of trust for verifying the SEV-SNP certificate chain.

    -
    • -
  • -

    AMD Signing Key Certificate

    -

    This is the intermediate certificate for verifying the SEV-SNP report's signature. -If it's not specified, the CLI fetches it from the AMD key distribution server.

    -
    • -
-

Cluster attestation​

-

Cluster-facing, Constellation's JoinService verifies each node joining the cluster given the configured ground truth runtime measurements. -User-facing, the VerificationService provides an interface to verify a node using remote attestation. -By verifying the first node during the initialization and configuring the ground truth measurements that are subsequently enforced by the JoinService, the whole cluster is verified in a transitive way.

-

Cluster-facing attestation​

-

The JoinService is provided with the runtime measurements of the whitelisted Constellation image version as the ground truth. -During the initialization and the cluster bootstrapping, each node connects to the JoinService using aTLS. -During the handshake, the node transmits an attestation statement including its runtime measurements. -The JoinService verifies that statement and compares the measurements against the ground truth. -For details of the initialization process check the microservice descriptions.

-

After the initialization, every node updates its runtime measurements with the clusterID value, marking it irreversibly as initialized. -When an initialized node tries to join another cluster, its measurements inevitably mismatch the measurements of an uninitialized node and it will be declined.

-

User-facing attestation​

-

The VerificationService provides an endpoint for obtaining its hardware-based remote attestation statement, which includes the runtime measurements. -A user can verify this statement and compare the measurements against the configured ground truth and, thus, verify the identity and integrity of all Constellation components and the cluster configuration. Subsequently, the user knows that the entire cluster is in the expected state and is trustworthy.

-

Putting it all together​

-

This section puts the aforementioned concepts together and illustrate how trust into a Constellation cluster is established and maintained.

-

CLI and node images​

-

It all starts with the CLI executable. The CLI is signed by Edgeless Systems. To ensure non-repudiability for CLI releases, Edgeless Systems publishes corresponding signatures to the public ledger of the sigstore project. There's a step-by-step guide on how to verify CLI signatures based on sigstore.

-

The CLI contains the latest runtime measurements of the Constellation node image for all supported cloud platforms. In case a different version of the node image is to be used, the corresponding runtime measurements can be fetched using the CLI's fetch-measurements command. This command downloads the runtime measurements and the corresponding signature from cdn.confidential.cloud. See for example the following files corresponding to node image v2.16.3:

- -

The CLI contains the long-term public key of Edgeless Systems to verify the signature of downloaded runtime measurements.

-

Cluster creation​

-

When a cluster is created, the CLI automatically verifies the runtime measurements of the first node using remote attestation. Based on this, the CLI and the first node set up a temporary TLS connection. This aTLS connection is used for two things:

-
    -
  1. The CLI sends the master secret of the to-be-created cluster to the CLI. The master secret is generated by the first node.
    2. -
  2. The first node sends a kubeconfig file with Kubernetes credentials to the CLI.
    3. -
-

After this, the aTLS connection is closed and the first node bootstraps the Kubernetes cluster. All subsequent interactions between the CLI and the cluster go via the Kubernetes API server running inside the cluster. The CLI (and other tools like kubectl) use the credentials referenced by the kubeconfig file to authenticate themselves towards the Kubernetes API server and to establish a mTLS connection.

-

The CLI connects to the Kubernetes API to write the runtime measurements for the applicable node image to etcd. The JoinService uses these runtime measurements to verify all nodes that join the cluster subsequently.

-

Chain of trust​

-

In summary, there's a chain of trust based on cryptographic signatures that goes from the user to the cluster via the CLI. This is illustrated in the following diagram.

- -

Upgrades​

-

Whenever a cluster is upgraded to a new version of the node image, the CLI sends the corresponding runtime measurements via the Kubernetes API server. The new runtime measurements are stored in etcd within the cluster and replace any previous runtime measurements. The new runtime measurements are then used automatically by the JoinService for the verification of new nodes.

Version: 2.23

Encrypted persistent storage

-

Confidential VMs provide runtime memory encryption to protect data in use. -In the context of Kubernetes, this is sufficient for the confidentiality and integrity of stateless services. -Consider a front-end web server, for example, that keeps all connection information cached in main memory. -No sensitive data is ever written to an insecure medium. -However, many real-world applications need some form of state or data-lake service that's connected to a persistent storage device and requires encryption at rest. -As described in Use persistent storage, cloud service providers (CSPs) use the container storage interface (CSI) to make their storage solutions available to Kubernetes workloads. -These CSI storage solutions often support some sort of encryption. -For example, Google Cloud encrypts data at rest by default, without any action required by the customer.

-

Cloud provider-managed encryption​

-

CSP-managed storage solutions encrypt the data in the cloud backend before writing it physically to disk. -In the context of confidential computing and Constellation, the CSP and its managed services aren't trusted. -Hence, cloud provider-managed encryption protects your data from offline hardware access to physical storage devices. -It doesn't protect it from anyone with infrastructure-level access to the storage backend or a malicious insider in the cloud platform. -Even with "bring your own key" or similar concepts, the CSP performs the encryption process with access to the keys and plaintext data.

-

In the security model of Constellation, securing persistent storage and thereby data at rest requires that all cryptographic operations are performed inside a trusted execution environment. -Consequently, using CSP-managed encryption of persistent storage usually isn't an option.

-

Constellation-managed encryption​

-

Constellation provides CSI drivers for storage solutions in all major clouds with built-in encryption support. -Block storage provisioned by the CSP is mapped using the dm-crypt, and optionally the dm-integrity, kernel modules, before it's formatted and accessed by the Kubernetes workloads. -All cryptographic operations happen inside the trusted environment of the confidential Constellation node.

-

Note that for integrity-protected disks, volume expansion isn't supported.

-

By default the driver uses data encryption keys (DEKs) issued by the Constellation KeyService. -The DEKs are in turn derived from the Constellation's key encryption key (KEK), which is directly derived from the master secret. -This is the recommended mode of operation, and also requires the least amount of setup by the cluster administrator.

-

Alternatively, the driver can be configured to use a key management system to store and access KEKs and DEKs.

-

Refer to keys and cryptography for more details on key management in Constellation.

-

Once deployed and configured, the CSI driver ensures transparent encryption and integrity of all persistent volumes provisioned via its storage class. -Data at rest is secured without any additional actions required by the developer.

-

Cryptographic algorithms​

-

This section gives an overview of the libraries, cryptographic algorithms, and their configurations, used in Constellation's CSI drivers.

-

dm-crypt​

-

To interact with the dm-crypt kernel module, Constellation uses libcryptsetup. -New devices are formatted as LUKS2 partitions with a sector size of 4096 bytes. -The used key derivation function is Argon2id with the recommended parameters for memory-constrained environments of 3 iterations and 64 MiB of memory, utilizing 4 parallel threads. -For encryption Constellation uses AES in XTS-Plain64. The key size is 512 bit.

-

dm-integrity​

-

To interact with the dm-integrity kernel module, Constellation uses libcryptsetup. -When enabled, the used data integrity algorithm is HMAC with SHA256 as the hash function. -The tag size is 32 Bytes.

-

Encrypted S3 object storage​

-

Constellation comes with a service that you can use to transparently retrofit client-side encryption to existing applications that use S3 (AWS or compatible) for storage. -To learn more, check out the s3proxy documentation.

Version: 2.23

Constellation images

-

Constellation uses a minimal version of Fedora as the operating system running inside confidential VMs. This Linux distribution is optimized for containers and designed to be stateless. -The Constellation images provide measured boot and an immutable filesystem.

-

Measured boot​

- -

Measured boot uses a Trusted Platform Module (TPM) to measure every part of the boot process. This allows for verification of the integrity of a running system at any point in time. To ensure correct measurements of every stage, each stage is responsible to measure the next stage before transitioning.

-

Firmware​

-

With confidential VMs, the firmware is the root of trust and is measured automatically at boot. After initialization, the firmware will load and measure the bootloader before executing it.

-

Bootloader​

-

The bootloader is the first modifiable part of the boot chain. The bootloader is tasked with loading the kernel, initramfs and setting the kernel command line. The Constellation bootloader measures these components before starting the kernel.

-

initramfs​

-

The initramfs is a small filesystem loaded to prepare the actual root filesystem. The Constellation initramfs maps the block device containing the root filesystem with dm-verity. The initramfs then mounts the root filesystem from the mapped block device.

-

dm-verity provides integrity checking using a cryptographic hash tree. When a block is read, its integrity is checked by verifying the tree against a trusted root hash. The initramfs reads this root hash from the previously measured kernel command line. Thus, if any block of the root filesystem's device is modified on disk, trying to read the modified block will result in a kernel panic at runtime.

-

After mounting the root filesystem, the initramfs will switch over and start the init process of the integrity-protected root filesystem.

-

State disk​

-

In addition to the read-only root filesystem, each Constellation node has a disk for storing state data. -This disk is mounted readable and writable by the initramfs and contains data that should persist across reboots. -Such data can contain sensitive information and, therefore, must be stored securely. -To that end, the state disk is protected by authenticated encryption. -See the section on keys and encryption for more information on the cryptographic primitives in use.

-

Kubernetes components​

-

During initialization, the Bootstrapper downloads and verifies the Kubernetes components as configured by the user. -They're stored on the state partition and can be updated once new releases need to be installed.

Version: 2.23

Key management and cryptographic primitives

-

Constellation protects and isolates your cluster and workloads. -To that end, cryptography is the foundation that ensures the confidentiality and integrity of all components. -Evaluating the security and compliance of Constellation requires a precise understanding of the cryptographic primitives and keys used. -The following gives an overview of the architecture and explains the technical details.

-

Confidential VMs​

-

Confidential VM (CVM) technology comes with hardware and software components for memory encryption, isolation, and remote attestation. -For details on the implementations and cryptographic soundness, refer to the hardware vendors' documentation and advisories.

-

Master secret​

-

The master secret is the cryptographic material used for deriving the clusterID and the key encryption key (KEK) for storage encryption. -It's generated during the bootstrapping of a Constellation cluster. -It can either be managed by Constellation or an external key management system. -In case of recovery, the master secret allows to decrypt the state and recover a Constellation cluster.

-

Cluster identity​

-

The identity of a Constellation cluster is represented by cryptographic measurements:

-

The base measurements represent the identity of a valid, uninitialized Constellation node. -They depend on the node image, but are otherwise the same for every Constellation cluster. -On node boot, they're determined using the CVM's attestation mechanism and measured boot up to the read-only root filesystem.

-

The clusterID represents the identity of a single initialized Constellation cluster. -It's derived from the master secret and a cryptographically random salt and unique for every Constellation cluster. -The Bootstrapper measures the clusterID into its own PCR before executing any code not measured as part of the base measurements. -See Node attestation for details.

-

The remote attestation statement of a Constellation cluster combines the base measurements and the clusterID for a verifiable, unspoofable, unique identity.

-

Network encryption​

-

Constellation encrypts all cluster network communication using the container network interface (CNI). -See network encryption for more details.

-

The Cilium agent running on each node establishes a secure WireGuard tunnel between it and all other known nodes in the cluster. -Each node creates its own Curve25519 encryption key pair and distributes its public key via Kubernetes. -A node uses another node's public key to decrypt and encrypt traffic from and to Cilium-managed endpoints running on that node. -Connections are always encrypted peer-to-peer using ChaCha20 with Poly1305. -WireGuard implements forward secrecy with key rotation every 2 minutes.

-

Storage encryption​

-

Constellation supports transparent encryption of persistent storage. -The Linux kernel's device mapper-based encryption features are used to encrypt the data on the block storage level. -Currently, the following primitives are used for block storage encryption:

- -

Adding primitives for integrity protection in the CVM attacker model are under active development and will be available in a future version of Constellation. -See encrypted storage for more details.

-

As a cluster administrator, when creating a cluster, you can use the Constellation installation program to select one of the following methods for key management:

-
    -
  • Constellation-managed key management
    • -
  • User-managed key management
    • -
-

Constellation-managed key management​

-

Key material and key derivation​

-

During the creation of a Constellation cluster, the cluster's master secret is used to derive a KEK. -This means creating two clusters with the same master secret will yield the same KEK. -Any data encryption key (DEK) is derived from the KEK via HKDF. -Note that the master secret is recommended to be unique for every cluster and shouldn't be reused (except in case of recovering a cluster).

-

State and storage​

-

The KEK is derived from the master secret during the initialization. -Subsequently, all other key material is derived from the KEK. -Given the same KEK, any DEK can be derived deterministically from a given identifier. -Hence, there is no need to store DEKs. They can be derived on demand. -After the KEK was derived, it's stored in memory only and never leaves the CVM context.

-

Availability​

-

Constellation-managed key management has the same availability as the underlying Kubernetes cluster. -Therefore, the KEK is stored in the distributed Kubernetes etcd storage to allow for unexpected but non-fatal (control-plane) node failure. -The etcd storage is backed by the encrypted and integrity protected state disk of the nodes.

-

Recovery​

-

Constellation clusters can be recovered in the event of a disaster, even when all node machines have been stopped and need to be rebooted. -For details on the process see the recovery workflow.

-

User-managed key management​

-

User-managed key management is under active development and will be available soon. -In scenarios where constellation-managed key management isn't an option, this mode allows you to keep full control of your keys. -For example, compliance requirements may force you to keep your KEKs in an on-prem key management system (KMS).

-

During the creation of a Constellation cluster, you specify a KEK present in a remote KMS. -This follows the common scheme of "bring your own key" (BYOK). -Constellation will support several KMSs for managing the storage and access of your KEK. -Initially, it will support the following KMSs:

- -

Storing the keys in Cloud KMS of AWS, Azure, or GCP binds the key usage to the particular cloud identity access management (IAM). -In the future, Constellation will support remote attestation-based access policies for Cloud KMS once available. -Note that using a Cloud KMS limits the isolation and protection to the guarantees of the particular offering.

-

KMIP support allows you to use your KMIP-compatible on-prem KMS and keep full control over your keys. -This follows the common scheme of "hold your own key" (HYOK).

-

The KEK is used to encrypt per-data "data encryption keys" (DEKs). -DEKs are generated to encrypt your data before storing it on persistent storage. -After being encrypted by the KEK, the DEKs are stored on dedicated cloud storage for persistence. -Currently, Constellation supports the following cloud storage options:

- -

The DEKs are only present in plaintext form in the encrypted main memory of the CVMs. -Similarly, the cryptographic operations for encrypting data before writing it to persistent storage are performed in the context of the CVMs.

-

Recovery and migration​

-

In the case of a disaster, the KEK can be used to decrypt the DEKs locally and subsequently use them to decrypt and retrieve the data. -In case of migration, configuring the same KEK will provide seamless migration of data. -Thus, only the DEK storage needs to be transferred to the new cluster alongside the encrypted data for seamless migration.

Microservices

-

Constellation takes care of bootstrapping and initializing a Confidential Kubernetes cluster. -During the lifetime of the cluster, it handles day 2 operations such as key management, remote attestation, and updates. -These features are provided by several microservices:

- -

The relations between microservices are shown in the following diagram:

- -

Bootstrapper​

-

The Bootstrapper is the first microservice launched after booting a Constellation node image. -It sets up that machine as a Kubernetes node and integrates that node into the Kubernetes cluster. -To this end, the Bootstrapper first downloads and verifies the Kubernetes components at the configured versions. -The Bootstrapper tries to find an existing cluster and if successful, communicates with the JoinService to join the node. -Otherwise, it waits for an initialization request to create a new Kubernetes cluster.

-

JoinService​

-

The JoinService runs as DaemonSet on each control-plane node. -New nodes (at cluster start, or later through autoscaling) send a request to the service over attested TLS (aTLS). -The JoinService verifies the new node's certificate and attestation statement. -If attestation is successful, the new node is supplied with an encryption key from the KeyService for its state disk, and a Kubernetes bootstrap token.

- -

VerificationService​

-

The VerificationService runs as DaemonSet on each node. -It provides user-facing functionality for remote attestation during the cluster's lifetime via an endpoint for verifying the cluster. -Read more about the hardware-based attestation feature of Constellation and how to verify a cluster on the client side.

-

KeyService​

-

The KeyService runs as DaemonSet on each control-plane node. -It implements the key management for the storage encryption keys in Constellation. These keys are used for the state disk of each node and the transparently encrypted storage for Kubernetes. -Depending on wether the constellation-managed or user-managed mode is used, the KeyService holds the key encryption key (KEK) directly or calls an external key management service (KMS) for key derivation respectively.

Network encryption

-

Constellation encrypts all pod communication using the container network interface (CNI). -To that end, Constellation deploys, configures, and operates the Cilium CNI plugin. -Cilium provides transparent encryption for all cluster traffic using either IPSec or WireGuard. -Currently, Constellation only supports WireGuard as the encryption engine. -You can read more about the cryptographic soundness of WireGuard in their white paper.

-

Cilium is actively working on implementing a feature called host-to-host encryption mode for WireGuard. -With host-to-host, all traffic between nodes will be tunneled via WireGuard (host-to-host, host-to-pod, pod-to-host, pod-to-pod). -Until the host-to-host feature is released, Constellation enables pod-to-pod encryption. -This mode encrypts all traffic between Kubernetes pods using WireGuard tunnels.

-

When using Cilium in the default setup but with encryption enabled, there is a known issue -that can cause pod-to-pod traffic to be unencrypted. -To mitigate this issue, Constellation adds a strict mode to Cilium's pod-to-pod encryption. -This mode changes the default behavior of traffic that's destined for an unknown endpoint to not be send out in plaintext, but instead being dropped. -The strict mode distinguishes between traffic that's send to a pod from traffic that's destined for a cluster-external endpoint by considering the pod's CIDR range.

-

Traffic originating from hosts isn't encrypted yet. -This mainly includes health checks from Kubernetes API server. -Also, traffic proxied over the API server via e.g. kubectl port-forward isn't encrypted.

Observability

-

In Kubernetes, observability is the ability to gain insight into the behavior and performance of applications. -It helps identify and resolve issues more effectively, ensuring stability and performance of Kubernetes workloads, reducing downtime and outages, and improving efficiency. -The "three pillars of observability" are logs, metrics, and traces.

-

In the context of Confidential Computing, observability is a delicate subject and needs to be applied such that it doesn't leak any sensitive information. -The following gives an overview of where and how you can apply standard observability tools in Constellation.

-

Cloud resource monitoring​

-

While inaccessible, Constellation's nodes are still visible as black box VMs to the hypervisor. -Resource consumption, such as memory and CPU utilization, can be monitored from the outside and observed via the cloud platforms directly. -Similarly, other resources, such as storage and network and their respective metrics, are visible via the cloud platform.

-

Metrics​

-

Metrics are numeric representations of data measured over intervals of time. They're essential for understanding system health and gaining insights using telemetry signals.

-

By default, Constellation exposes the metrics for Kubernetes system components inside the cluster. -Similarly, the etcd metrics endpoints are exposed inside the cluster. -These metrics endpoints can be disabled.

-

You can collect these cluster-internal metrics via tools such as Prometheus or the Elastic Stack.

-

Constellation's CNI Cilium also supports metrics via Prometheus endpoints. -However, in Constellation, they're disabled by default and must be enabled first.

-

Logs​

-

Logs represent discrete events that usually describe what's happening with your service. -The payload is an actual message emitted from your system along with a metadata section containing a timestamp, labels, and tracking identifiers.

-

System logs​

-

Detailed system-level logs are accessible via /var/log and journald on the nodes directly. -They can be collected from there, for example, via Filebeat and Logstash, which are tools of the Elastic Stack.

-

In case of an error during the initialization, the CLI automatically collects the Bootstrapper logs and returns these as a file for troubleshooting. Here is an example of such an event:

-
Cluster initialization failed. This error is not recoverable.
Terminate your cluster and try again.
Fetched bootstrapper logs are stored in "constellation-cluster.log"
-

Kubernetes logs​

-

Constellation supports the Kubernetes logging architecture. -By default, logs are written to the nodes' encrypted state disks. -These include the Pod and container logs and the system component logs.

-

Constellation services run as Pods inside the kube-system namespace and use the standard container logging mechanism. -The same applies for the Cilium Pods.

-

You can collect logs from within the cluster via tools such as Fluentd, Loki, or the Elastic Stack.

-

Traces​

-

Modern systems are implemented as interconnected complex and distributed microservices. Understanding request flows and system communications is challenging, mainly because all systems in a chain need to be modified to propagate tracing information. Distributed tracing is a new approach to increasing observability and understanding performance bottlenecks. A trace represents consecutive events that reflect an end-to-end request path in a distributed system.

-

Constellation supports traces for Kubernetes system components. -By default, they're disabled and need to be enabled first.

-

Similarly, Cilium can be enabled to export traces.

-

You can collect these traces via tools such as Jaeger or Zipkin.

-

Integrations​

-

Platforms and SaaS solutions such as Datadog, logz.io, Dynatrace, or New Relic facilitate the observability challenge for Kubernetes and provide all-in-one SaaS solutions. -They install agents into the cluster that collect metrics, logs, and tracing information and upload them into the data lake of the platform. -Technically, the agent-based approach is compatible with Constellation, and attaching these platforms is straightforward. -However, you need to evaluate if the exported data might violate Constellation's compliance and privacy guarantees by uploading them to a third-party platform.

Orchestrating Constellation clusters

-

You can use the CLI to create a cluster on the supported cloud platforms. -The CLI provisions the resources in your cloud environment and initiates the initialization of your cluster. -It uses a set of parameters and an optional configuration file to manage your cluster installation. -The CLI is also used for updating your cluster.

-

Workspaces​

-

Each Constellation cluster has an associated workspace. -The workspace is where data such as the Constellation state and config files are stored. -Each workspace is associated with a single cluster and configuration. -The CLI stores state in the local filesystem making the current directory the active workspace. -Multiple clusters require multiple workspaces, hence, multiple directories. -Note that every operation on a cluster always has to be performed from the directory associated with its workspace.

-

You may copy files from the workspace to other locations, -but you shouldn't move or delete them while the cluster is still being used. -The Constellation CLI takes care of managing the workspace. -Only when a cluster was terminated, and you are sure the files aren't needed anymore, should you remove a workspace.

-

Cluster creation process​

-

To allow for fine-grained configuration of your cluster and cloud environment, Constellation supports an extensive configuration file with strong defaults. Generating the configuration file is typically the first thing you do in the workspace.

-

Altogether, the following files are generated during the creation of a Constellation cluster and stored in the current workspace:

-
    -
  • a configuration file
    • -
  • a state file
    • -
  • a Base64-encoded master secret
    • -
  • Terraform artifacts, stored in subdirectories
    • -
  • a Kubernetes kubeconfig file.
    • -
-

After the initialization of your cluster, the CLI will provide you with a Kubernetes kubeconfig file. -This file grants you access to your Kubernetes cluster and configures the kubectl tool. -In addition, the cluster's identifier is returned and stored in the state file.

-

Creation process details​

-
    -
  1. The CLI apply command first creates the confidential VM (CVM) resources in your cloud environment and configures the network
    2. -
  2. Each CVM boots the Constellation node image and measures every component in the boot chain
    3. -
  3. The first microservice launched in each node is the Bootstrapper
    4. -
  4. The Bootstrapper waits until it either receives an initialization request or discovers an initialized cluster
    5. -
  5. The CLI then connects to the Bootstrapper of a selected node, sends the configuration, and initiates the initialization of the cluster
    6. -
  6. The Bootstrapper of that node initializes the Kubernetes cluster and deploys the other Constellation microservices including the JoinService
    7. -
  7. Subsequently, the Bootstrappers of the other nodes discover the initialized cluster and send join requests to the JoinService
    8. -
  8. As part of the join request each node includes an attestation statement of its boot measurements as authentication
    9. -
  9. The JoinService verifies the attestation statements and joins the nodes to the Kubernetes cluster
    10. -
  10. This process is repeated for every node joining the cluster later (e.g., through autoscaling)
    11. -
-

Post-installation configuration​

-

Post-installation the CLI provides a configuration for accessing the cluster using the Kubernetes API. -The kubeconfig file provides the credentials and configuration for connecting and authenticating to the API server. -Once configured, orchestrate the Kubernetes cluster via kubectl.

-

After the initialization, the CLI will present you with a couple of tokens:

-
    -
  • The master secret (stored in the constellation-mastersecret.json file by default)
    • -
  • The clusterID of your cluster in Base64 encoding
    • -
-

You can read more about these values and their meaning in the guide on cluster identity.

-

The master secret must be kept secret and can be used to recover your cluster. -Instead of managing this secret manually, you can use your key management solution of choice with Constellation.

-

The clusterID uniquely identifies a cluster and can be used to verify your cluster.

-

Upgrades​

-

Constellation images and microservices may need to be upgraded to new versions during the lifetime of a cluster. -Constellation implements a rolling update mechanism ensuring no downtime of the control or data plane. -You can upgrade a Constellation cluster with a single operation by using the CLI. -For step-by-step instructions on how to do this, refer to Upgrade your cluster.

-

Attestation of upgrades​

-

With every new image, corresponding measurements are released. -During an update procedure, the CLI provides new measurements to the JoinService securely. -New measurements for an updated image are automatically pulled and verified by the CLI following the supply chain security concept of Constellation. -The attestation section describes in detail how these measurements are then used by the JoinService for the attestation of nodes.

Versions and support policy

-

All components of Constellation use a three-digit version number of the form v<MAJOR>.<MINOR>.<PATCH>. -The components are released in lock step, usually on the first Tuesday of every month. This release primarily introduces new features, but may also include security or performance improvements. The MINOR version will be incremented as part of this release.

-

Additional PATCH releases may be created on demand, to fix security issues or bugs before the next MINOR release window.

-

New releases are published on GitHub.

-

Kubernetes support policy​

-

Constellation is aligned to the version support policy of Kubernetes, and therefore usually supports the most recent three minor versions. -When a new minor version of Kubernetes is released, support is added to the next Constellation release, and that version then supports four Kubernetes versions. -Subsequent Constellation releases drop support for the oldest (and deprecated) Kubernetes version.

Basics

📄️ Security benefits

Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

The pod spec includes the hostAliases key, which adds an entry to the pod's /etc/hosts. -The entry forwards all requests for any of the currently defined AWS regions to the Kubernetes service s3proxy-service. -If you followed the s3proxy Deployment guide, this service points to a s3proxy pod.

-

The deployment specifies all regions explicitly to prevent accidental data leaks. -If one of your buckets were located in a region that's not part of the hostAliases key, traffic towards those buckets would not be redirected to s3proxy. -Similarly, if you want to exclude data for specific regions from going through s3proxy you can remove those regions from the deployment.

-

The spec also includes a volume mount for the TLS certificate and adds it to the pod's certificate trust store. -The volume is called ca-cert. -The key ca.crt of that volume is mounted to /etc/ssl/certs/kube-ca.crt, which is the default certificate trust store location for that container's OpenSSL library. -Not adding the CA certificate will result in TLS authentication errors.

  1. Apply the file: kubectl apply -f deployment-filestash.yaml
    2. -
-

Afterward, you can use a port forward to access the Filestash pod: -kubectl port-forward pod/$(kubectl get pod --selector='app=filestash' -o=jsonpath='{.items[*].metadata.name}') 8334:8334

-
    -

    After browsing to localhost:8443, Filestash will ask you to set an administrator password. -After setting it, you can directly leave the admin area by clicking the blue cloud symbol in the top left corner. -Subsequently, you can select S3 as storage backend and enter your credentials. -This will bring you to an overview of your buckets. -If you want to deploy Filestash in production, take a look at its documentation.

    -

    To see the logs of s3proxy intercepting requests made to S3, run: kubectl logs -f pod/$(kubectl get pod --selector='app=s3proxy' -o=jsonpath='{.items[*].metadata.name}') -Look out for log messages labeled intercepting. -There is one such log message for each message that's encrypted, decrypted, or blocked.

    -
    3. -
  3. -

    Once you have uploaded a file with Filestash, you should be able to view the file in Filestash. -However, if you go to the AWS S3 Web UI and download the file you just uploaded in Filestash, you won't be able to read it. -Another way to spot encrypted files without downloading them is to click on a file, scroll to the Metadata section, and look for the header named x-amz-meta-constellation-encryption. -This header holds the encrypted data encryption key of the object and is only present on objects that are encrypted by s3proxy.

Horizontal Pod Autoscaling

-

This example demonstrates Constellation's autoscaling capabilities. It's based on the Kubernetes HorizontalPodAutoscaler Walkthrough. During the following steps, Constellation will spawn new VMs on demand, verify them, add them to the cluster, and delete them again when the load has settled down.

-

Requirements​

-

The cluster needs to be initialized with Kubernetes 1.23 or later. In addition, autoscaling must be enabled to enable Constellation to assign new nodes dynamically.

-

Just for this example specifically, the cluster should have as few worker nodes in the beginning as possible. Start with a small cluster with only one low-powered node for the control-plane node and one low-powered worker node.

-
info

We tested the example using instances of types Standard_DC4as_v5 on Azure and n2d-standard-4 on GCP.

-

Setup​

-
    -
  1. -

    Install the Kubernetes Metrics Server:

    -
    kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
    -
    2. -
  2. -

    Deploy the HPA example server that's supposed to be scaled under load.

    -

    This manifest is similar to the one from the Kubernetes HPA walkthrough, but with increased CPU limits and requests to facilitate the triggering of node scaling events.

    -

    Create a HorizontalPodAutoscaler.

    -

    Set an average CPU usage across all Pods of 20% to see one additional worker node being created later. Note that the CPU usage isn't related to the host CPU usage, but rather to the requested CPU capacities (20% of 600 milli-cores CPU across all Pods). See the original tutorial for more information on the HPA configuration.

    -
    kubectl autoscale deployment php-apache --cpu-percent=20 --min=1 --max=10
    -
    4. -
  4. -

    Create a Pod that generates load on the server:

    -
    kubectl run -i --tty load-generator --rm --image=busybox:1.28 --restart=Never -- /bin/sh -c "while true; do wget -q -O- http://php-apache; done"
    -
    5. -
  5. -

    Wait a few minutes until new nodes are added to the cluster. You can monitor the state of the HorizontalPodAutoscaler, the list of nodes, and the behavior of the autoscaler.

    -
    6. -
  6. -

    To stop the load generator, press CTRL+C and run:

    -
    kubectl delete pod load-generator
    -
    7. -
  7. -

    The cluster-autoscaler checks every few minutes if nodes are underutilized. It will taint such candidates for removal and wait additional 10 minutes before the nodes are eventually removed and deallocated. The whole process can take about 20 minutes.

    -
    8. -
-

Monitoring​

-
tip

For better observability, run the listed commands in different tabs in your terminal.

-

You can watch the status of the HorizontalPodAutoscaler with the current CPU usage, the target CPU limit, and the number of replicas created with:

-
kubectl get hpa php-apache --watch
-

From time to time compare the list of nodes to check the behavior of the autoscaler:

-
kubectl get nodes
-

For deeper insights, see the logs of the autoscaler Pod, which contains more details about the scaling decision process:

-
kubectl logs -f deployment/constellation-cluster-autoscaler -n kube-system

Version: 2.23

First steps with a local cluster

-

A local cluster lets you deploy and test Constellation without a cloud subscription. -You have two options:

-
    -
  • Use MiniConstellation to automatically deploy a two-node cluster.
    • -
  • For more fine-grained control, create the cluster using the QEMU provider.
    • -
-

Both options use virtualization to create a local cluster with control-plane nodes and worker nodes. They don't require hardware with Confidential VM (CVM) support. For attestation, they currently use a software-based vTPM provided by KVM/QEMU.

-

You need an x64 machine with a Linux OS. -You can use a VM, but it needs nested virtualization.

-

Prerequisites​

-
    -
  • Machine requirements: -
      -
    • An x86-64 CPU with at least 4 cores (6 cores are recommended)
      • -
    • At least 4 GB RAM (6 GB are recommended)
      • -
    • 20 GB of free disk space
      • -
    • Hardware virtualization enabled in the BIOS/UEFI (often referred to as Intel VT-x or AMD-V/SVM) / nested-virtualization support when using a VM
      • -
    -
    • -
  • Software requirements: - -
    • -
-

Software installation on Ubuntu​

-
# install Docker
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt update
sudo apt install docker-ce
# install other dependencies
sudo apt install xsltproc
sudo snap install kubectl --classic
# install Constellation CLI
curl -LO https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64
sudo install constellation-linux-amd64 /usr/local/bin/constellation
# do not drop forwarded packages
sudo iptables -P FORWARD ACCEPT
-

Create a cluster​

-

With the constellation mini command, you can deploy and test Constellation locally. This mode is called MiniConstellation. Conceptually, MiniConstellation is similar to MicroK8s, K3s, and minikube.

caution

MiniConstellation has specific soft- and hardware requirements such as a Linux OS running on an x86-64 CPU. Pay attention to all prerequisites when setting up.

note

Since MiniConstellation runs on your local system, cloud features such as load balancing, -attaching persistent storage, or autoscaling aren't available.

The following creates your MiniConstellation cluster (may take up to 10 minutes to complete):

constellation mini up

This will configure your current directory as the workspace for this cluster. -All constellation commands concerning this cluster need to be issued from this directory.

-

Connect to the cluster​

-

Your cluster initially consists of a single control-plane node:

-
$ kubectl get nodes
NAME              STATUS   ROLES           AGE   VERSION
control-plane-0   Ready    control-plane   66s   v1.24.6
-

Additional nodes will request to join the cluster shortly. Before each additional node is allowed to join the cluster, its state is verified using remote attestation by the JoinService. -If verification passes successfully, the new node receives keys and certificates to join the cluster.

-

You can follow this process by viewing the logs of the JoinService:

-
$ kubectl logs -n kube-system daemonsets/join-service -f
{"level":"INFO","ts":"2022-10-14T09:32:20Z","caller":"cmd/main.go:48","msg":"Constellation Node Join Service","version":"2.1.0","cloudProvider":"qemu"}
{"level":"INFO","ts":"2022-10-14T09:32:20Z","logger":"validator","caller":"watcher/validator.go:96","msg":"Updating expected measurements"}
...
-

Once all nodes have joined your cluster, it may take a couple of minutes for all resources to become available. -You can check on the state of your cluster by running the following:

-
$ kubectl get nodes
NAME              STATUS   ROLES           AGE     VERSION
control-plane-0   Ready    control-plane   2m59s   v1.24.6
worker-0          Ready    <none>          32s     v1.24.6
-

Deploy a sample application​

-
    -
  1. Deploy the emojivoto app
    2. -
-
kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
-
    -
  1. Expose the frontend service locally
    2. -
-
kubectl wait --for=condition=available --timeout=60s -n emojivoto --all deployments
kubectl -n emojivoto port-forward svc/web-svc 8080:80 &
curl http://localhost:8080
kill %1
-

Terminate your cluster​

-

Once you are done, you can clean up the created resources using the following command:

constellation mini down

This will destroy your cluster and clean up your workspace. -The VM image and cluster configuration file (constellation-conf.yaml) will be kept and may be reused to create new clusters.

-

Troubleshooting​

-

Make sure to use the latest release and check out the known issues.

-

VMs have no internet access / CLI remains in "Initializing cluster" state​

-

iptables rules may prevent your VMs from accessing the internet. -Make sure your rules aren't dropping forwarded packages.

-

List your rules:

-
sudo iptables -S
-

The output may look similar to the following:

-
-P INPUT ACCEPT
-P FORWARD DROP
-P OUTPUT ACCEPT
-N DOCKER
-N DOCKER-ISOLATION-STAGE-1
-N DOCKER-ISOLATION-STAGE-2
-N DOCKER-USER
-

If your FORWARD chain is set to DROP, you need to update your rules:

First steps with Constellation

-

The following steps guide you through the process of creating a cluster and deploying a sample app. This example assumes that you have successfully installed and set up Constellation, -and have access to a cloud subscription.

-
tip

If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

-
note

If you encounter any problem with the following steps, make sure to use the latest release and check out the known issues.

-

Create a cluster​

-
    -
  1. -

    Create the configuration file and state file for your cloud provider. If you are following the steps of this guide, there is no need to edit the file.

    -
    constellation config generate aws
    -
    2. -
  2. -

    Create your IAM configuration.

    -
    constellation iam create aws --zone=us-east-2a --prefix=constellTest --update-config

    This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created. It also updates the configuration file constellation-conf.yaml in your current directory with the IAM values filled in.

    Depending on the attestation variant selected on config generation, different regions are available. -AMD SEV-SNP machines (requires the default attestation variant awsSEVSNP) are currently available in the following regions:

      -
    • eu-west-1
      • -
    • us-east-2
      • -

    You can find a list of regions that support AMD SEV-SNP in AWS's documentation.

    NitroTPM machines (requires the attestation variant awsNitroTPM) are available in all regions. -Constellation OS images are currently replicated to the following regions:

      -
    • eu-central-1
      • -
    • eu-west-1
      • -
    • eu-west-3
      • -
    • us-east-2

Version: 2.23

Installation and setup

-

Constellation runs entirely in your cloud environment and can be controlled via a dedicated command-line interface (CLI) or a Terraform provider.

-

Prerequisites​

-

Make sure the following requirements are met:

-
    -
  • Your machine is running Linux, macOS, or Windows
    • -
  • You have admin rights on your machine
    • -
  • kubectl is installed
    • -
  • Your CSP is Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), or STACKIT
    • -
-

Install the Constellation CLI​

-
tip

If you prefer to use Terraform, you can alternatively use the Terraform provider to manage the cluster's lifecycle.

-

The CLI executable is available at GitHub. -Install it with the following commands:

-
    -
  1. Download the CLI:
    2. -
curl -LO https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64
    -
  1. -

    Verify the signature (optional)

    -
    2. -
  2. -

    Install the CLI to your PATH:

    -
    3. -
sudo install constellation-linux-amd64 /usr/local/bin/constellation
-
tip

The CLI supports autocompletion for various shells. To set it up, run constellation completion and follow the given steps.

-

Set up cloud credentials​

-

Constellation makes authenticated calls to the CSP API. Therefore, you need to set up Constellation with the credentials for your CSP.

-
tip

If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

-

Required permissions​

-

To set up a Constellation cluster, you need to perform two tasks that require permissions: create the infrastructure and create roles for cluster nodes. Both of these actions can be performed by different users, e.g., an administrator to create roles and a DevOps engineer to create the infrastructure.

To create the IAM configuration for Constellation, you need the following permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",

Authentication​

-

You need to authenticate with your CSP. The following lists the required steps for testing and production environments.

-
note

The steps for a testing environment are simpler. However, they may expose secrets to the CSP. If in doubt, follow the production steps.

-

Testing

You can use the AWS CloudShell. Make sure you are authorized to use it.

Production

Use the latest version of the AWS CLI on a trusted machine:

aws configure

Options and first steps are described in the AWS CLI documentation.

-

Next steps​

-

You are now ready to deploy your first confidential Kubernetes cluster and application.

Using Constellation via Cloud Marketplaces

-

Constellation is available through the Marketplaces of AWS, Azure, GCP, and STACKIT. This allows you to create self-managed Constellation clusters that are billed on a pay-per-use basis (hourly, per vCPU) with your CSP account. You can still get direct support by Edgeless Systems. For more information, please contact us.

-

This document explains how to run Constellation with the dynamically billed cloud marketplace images.

-

To use Constellation's marketplace images, ensure that you are subscribed to the marketplace offering through the web portal.

Then, enable the use of marketplace images in your Constellation constellation-conf.yaml config file:

yq eval -i ".provider.aws.useMarketplaceImage = true" constellation-conf.yaml
-

Ensure that the cluster uses an official release image version (i.e., .image=vX.Y.Z in the constellation-conf.yaml file).

-

From there, you can proceed with the cluster creation as usual.

Introduction

-

Welcome to the documentation of Constellation! Constellation is a Kubernetes engine that aims to provide the best possible data security.

-

Constellation concept

-

Constellation shields your entire Kubernetes cluster from the underlying cloud infrastructure. Everything inside is always encrypted, including at runtime in memory. For this, Constellation leverages a technology called confidential computing and more specifically Confidential VMs.

-
tip

See the 📄whitepaper for more information on confidential computing.

-

Goals​

-

From a security perspective, Constellation is designed to keep all data always encrypted and to prevent any access from the underlying (cloud) infrastructure. This includes access from datacenter employees, privileged cloud admins, and attackers coming through the infrastructure. Such attackers could be malicious co-tenants escalating their privileges or hackers who managed to compromise a cloud server.

-

From a DevOps perspective, Constellation is designed to work just like what you would expect from a modern Kubernetes engine.

-

Use cases​

-

Constellation provides unique security features and benefits. The core use cases are:

-
    -
  • Increasing the overall security of your clusters
    • -
  • Increasing the trustworthiness of your SaaS offerings
    • -
  • Moving sensitive workloads from on-prem to the cloud
    • -
  • Meeting regulatory requirements
    • -
-

Next steps​

-

You can learn more about the concept of Confidential Kubernetes, features, security benefits, and performance of Constellation in the Basics section. To jump right into the action head to Getting started.

Feature status of clouds

-

What works on which cloud? Currently, Confidential VMs (CVMs) are available in varying quality on the different clouds and software stacks.

-

For Constellation, the ideal environment provides the following:

-
    -
  1. Ability to run arbitrary software and images inside CVMs
    2. -
  2. CVMs based on AMD SEV-SNP (available in EPYC CPUs since the Milan generation) or Intel TDX (available in Xeon CPUs since the Sapphire Rapids generation)
    3. -
  3. Ability for CVM guests to obtain raw hardware attestation statements
    4. -
  4. Reviewable, open-source firmware inside CVMs
    5. -
  5. Capability of the firmware to attest the integrity of the code it passes control to, e.g., with an embedded virtual TPM (vTPM)
    6. -
-

(1) is a functional must-have. (2)--(5) are required for remote attestation that fully keeps the infrastructure/cloud out. Constellation can work without them or with approximations, but won't protect against certain privileged attackers anymore.

Amazon Web Services (AWS)​

-

Amazon EC2 supports AMD SEV-SNP. -Regarding (3), AWS provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the NitroTPM for measured boot, which is a vTPM managed by the Nitro hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the firmware is open source and can be reproducibly built.

-

Microsoft Azure​

-

With its CVM offering, Azure provides the best foundations for Constellation. -Regarding (3), Azure provides direct access to attestation statements. -The firmware runs in an isolated domain inside the CVM and exposes a vTPM (5), but it's closed source (4). -On SEV-SNP, Azure uses VM Privilege Level (VMPL) isolation for the separation of firmware and the rest of the VM; on TDX, they use TD partitioning. -This firmware is signed by Azure. -The signature is reflected in the attestation statements of CVMs. -Thus, the Azure closed-source firmware becomes part of Constellation's trusted computing base (TCB).

-

* Recently, Azure announced the open source paravisor OpenHCL. It's the foundation for fully open source and verifiable CVM firmware. Once Azure provides their CVM firmware with reproducible builds based on OpenHCL, (4) switches from No to Yes. Constellation will support OpenHCL based firmware on Azure in the future.

-

Google Cloud Platform (GCP)​

-

The CVMs Generally Available in GCP are based on AMD SEV-ES or SEV-SNP. -Regarding (3), with their SEV-SNP offering Google provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the Shielded VM vTPM for measured boot, which is a vTPM managed by Google's hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the CVMs still include closed-source firmware.

-

TDX on Google is in public preview. -With it, Constellation would have a similar TCB and attestation flow as with the current SEV-SNP offering.

-

STACKIT​

-

STACKIT Compute Engine supports AMD SEV-ES. A vTPM is used for measured boot, which is a vTPM managed by STACKIT's hypervisor. Hence, the hypervisor is currently part of Constellation's TCB.

-

OpenStack​

-

OpenStack is an open-source cloud and infrastructure management software. It's used by many smaller CSPs and datacenters. In the latest Yoga version, OpenStack has basic support for CVMs. However, much depends on the employed kernel and hypervisor. Features (2)--(4) are likely to be a Yes with Linux kernel version 6.2. Thus, going forward, OpenStack on corresponding AMD or Intel hardware will be a viable underpinning for Constellation.

-

Conclusion​

-

The different clouds and software like the Linux kernel and OpenStack are in the process of building out their support for state-of-the-art CVMs. Azure has already most features in place. For Constellation, the status quo means that the TCB has different shapes on different infrastructures. With broad SEV-SNP support coming to the Linux kernel, we soon expect a normalization of features across infrastructures.

Confidential Kubernetes

-

We use the term Confidential Kubernetes to refer to the concept of using confidential-computing technology to shield entire Kubernetes clusters from the infrastructure. The three defining properties of this concept are:

-
    -
  1. Workload shielding: the confidentiality and integrity of all workload-related data and code are enforced.
    2. -
  2. Control plane shielding: the confidentiality and integrity of the cluster's control plane, state, and workload configuration are enforced.
    3. -
  3. Attestation and verifiability: the two properties above can be verified remotely based on hardware-rooted cryptographic certificates.
    4. -
-

Each of the above properties is equally important. Only with all three in conjunction, an entire cluster can be shielded without gaps.

-

Constellation security features​

-

Constellation implements the Confidential Kubernetes concept with the following security features.

-
    -
  • Runtime encryption: Constellation runs all Kubernetes nodes inside Confidential VMs (CVMs). This gives runtime encryption for the entire cluster.
    • -
  • Network and storage encryption: Constellation augments this with transparent encryption of the network, persistent storage, and other managed storage like AWS S3. Thus, workloads and control plane are truly end-to-end encrypted: at rest, in transit, and at runtime.
    • -
  • Transparent key management: Constellation manages the corresponding cryptographic keys inside CVMs.
    • -
  • Node attestation and verification: Constellation verifies the integrity of each new CVM-based node using remote attestation. Only "good" nodes receive the cryptographic keys required to access the network and storage of a cluster.
    • -
  • Confidential computing-optimized images: A node is "good" if it's running a signed Constellation node image inside a CVM and is in the expected state. (Node images are hardware-measured during boot. The measurements are reflected in the attestation statements that are produced by nodes and verified by Constellation.)
    • -
  • "Whole cluster" attestation: Towards the DevOps engineer, Constellation provides a single hardware-rooted certificate from which all of the above can be verified.
    • -
-

With the above, Constellation wraps an entire cluster into one coherent and verifiable confidential context. The concept is depicted in the following.

-

Confidential Kubernetes

-

Comparison: Managed Kubernetes with CVMs​

-

In comparison, managed Kubernetes with CVMs, as it's for example offered in AKS and GKE, only provides runtime encryption for certain worker nodes. Here, each worker node is a separate (and typically unverified) confidential context. This only provides limited security benefits as it only prevents direct access to a worker node's memory. The large majority of potential attacks through the infrastructure remain unaffected. This includes attacks through the control plane, access to external key management, and the corruption of worker node images. This leaves many problems unsolved. For instance, Node A has no means to verify if Node B is "good" and if it's OK to share data with it. Consequently, this approach leaves a large attack surface, as is depicted in the following.

-

HashiCorp Vault​

-

HashiCorp Vault is a distributed secrets management software that can be deployed to Kubernetes. -HashiCorp maintains a benchmarking tool for vault, vault-benchmark. -Vault-benchmark generates load on a Vault deployment and measures response times.

-

This article describes the results from running vault-benchmark on Constellation, AKS, and GKE. -You can find the setup for producing the data discussed in this article in the vault-benchmarks repository.

-

The Vault API used during benchmarking is the transits secret engine. -This allows services to send data to Vault for encryption, decryption, signing, and verification.

-

Results​

-

On each run, vault-benchmark sends requests and measures the latencies. -The measured latencies are aggregated through various statistical features. -After running the benchmark n times, the arithmetic mean over a subset of the reported statistics is calculated. -The selected features are arithmetic mean, 99th percentile, minimum, and maximum.

-

Arithmetic mean gives a general sense of the latency on each target. -The 99th percentile shows performance in (most likely) erroneous states. -Minimum and maximum mark the range within which latency varies each run.

-

The benchmark was configured with 1300 workers and 10 seconds per run. -Those numbers were chosen empirically. -The latency was stabilizing at 10 seconds runtime, not changing with further increase. -Increasing the number of workers beyond 1300 leads to request failures, marking the limit Vault was able to handle in this setup. -All results are based on 100 runs.

-

The following data was generated while running five replicas, one primary, and four standby nodes. -All numbers are in seconds if not indicated otherwise.

Impact of runtime encryption on compute performance

-

All nodes in a Constellation cluster are executed inside Confidential VMs (CVMs). Consequently, the performance of Constellation is inherently linked to the performance of these CVMs.

-

AMD and Azure benchmarking​

-

AMD and Azure have collectively released a performance benchmark for CVMs that utilize 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. This benchmark, which included a variety of mostly compute-intensive tests such as SPEC CPU 2017 and CoreMark, demonstrated that CVMs experience only minor performance degradation (ranging from 2% to 8%) when compared to standard VMs. Such results are indicative of the performance that can be expected from compute-intensive workloads running with Constellation on Azure.

-

AMD and Google benchmarking​

-

Similarly, AMD and Google have jointly released a performance benchmark for CVMs employing 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. With high-performance computing workloads such as WRF, NAMD, Ansys CFS, and Ansys LS_DYNA, they observed analogous findings, with only minor performance degradation (between 2% and 4%) compared to standard VMs. These outcomes are reflective of the performance that can be expected for compute-intensive workloads running with Constellation on GCP.

AKS​

-

On AKS, the benchmark used Kubernetes v1.24.9 and nodes with version AKSUbuntu-1804gen2containerd-2023.02.15. -AKS ran with the kubenet CNI and the default CSI driver for Azure Disk.

Results​

-

Network​

-

This section gives a thorough analysis of the network performance of Constellation, specifically focusing on measuring TCP and UDP bandwidth. -The benchmark measured the bandwidth of pod-to-pod and pod-to-service connections between two different nodes using iperf.

-

GKE and Constellation on GCP had a maximum network bandwidth of 10 Gbps. -AKS with Standard_D4as_v5 machines a maximum network bandwidth of 12.5 Gbps. -The Confidential VM equivalent Standard_DC4as_v5 currently has a network bandwidth of 1.25 Gbps. -Therefore, to make the test comparable, both AKS and Constellation on Azure were running with Standard_DC4as_v5 machines and 1.25 Gbps bandwidth.

-

Constellation on Azure and AKS used an MTU of 1500. -Constellation on GCP used an MTU of 8896. GKE used an MTU of 1450.

-

The difference in network bandwidth can largely be attributed to two factors.

- -

Pod-to-Pod​

-

In this scenario, the client Pod connects directly to the server pod via its IP address.

- -

The results for "Pod-to-Pod" on Azure are as follows:

-

Network Pod2Pod Azure benchmark graph

-

The results for "Pod-to-Pod" on GCP are as follows:

-

Network Pod2Pod GCP benchmark graph

-

Pod-to-Service​

-

In this scenario, the client Pod connects to the server Pod via a ClusterIP service. This is more relevant to real-world use cases.

- -

The results for "Pod-to-Pod" on Azure are as follows:

-

Network Pod2SVC Azure benchmark graph

-

The results for "Pod-to-Pod" on GCP are as follows:

-

Network Pod2SVC GCP benchmark graph

-

In our recent comparison of Constellation on GCP with GKE, Constellation has 58% less TCP bandwidth. However, UDP bandwidth was slightly better with Constellation, thanks to its higher MTU.

-

Similarly, when comparing Constellation on Azure with AKS using CVMs, Constellation achieved approximately 10% less TCP and 40% less UDP bandwidth.

-

Storage I/O​

-

Azure and GCP offer persistent storage for their Kubernetes services AKS and GKE via the Container Storage Interface (CSI). CSI storage in Kubernetes is available via PersistentVolumes (PV) and consumed via PersistentVolumeClaims (PVC). -Upon requesting persistent storage through a PVC, GKE and AKS will provision a PV as defined by a default storage class. -Constellation provides persistent storage on Azure and GCP that's encrypted on the CSI layer. -Similarly, upon a PVC request, Constellation will provision a PV via a default storage class.

-

For Constellation on Azure and AKS, the benchmark ran with Azure Disk storage Standard SSD of 400 GiB size. -The DC4as machine type with four cores provides the following maximum performance:

-
    -
  • 6400 (20000 burst) IOPS
    • -
  • 144 MB/s (600 MB/s burst) throughput
    • -
-

However, the performance is bound by the capabilities of the 512 GiB Standard SSD size (the size class of 400 GiB volumes):

-
    -
  • 500 (600 burst) IOPS
    • -
  • 60 MB/s (150 MB/s burst) throughput
    • -

For Constellation on GCP and GKE, the benchmark ran with Compute Engine Persistent Disk Storage pd-balanced of 400 GiB size. -The N2D machine type with four cores and pd-balanced provides the following maximum performance:

-
    -
  • 3,000 read IOPS
    • -
  • 15,000 write IOPS
    • -
  • 240 MB/s read throughput
    • -
  • 240 MB/s write throughput
    • -
-

However, the performance is bound by the capabilities of a Zonal balanced PD with 400 GiB size:

-
    -
  • 2400 read IOPS
    • -
  • 2400 write IOPS
    • -
  • 112 MB/s read throughput
    • -
  • 112 MB/s write throughput
    • -
-

The fio benchmark consists of several tests. -The benchmark used Kubestr to run fio in Kubernetes. -The default test performs randomized access patterns that accurately depict worst-case I/O scenarios for most applications.

-

The following fio settings were used:

-
    -
  • No Cloud caching
    • -
  • No OS caching
    • -
  • Single CPU
    • -
  • 60 seconds runtime
    • -
  • 10 seconds ramp-up time
    • -
  • 10 GiB file
    • -
  • IOPS: 4 KB blocks and 128 iodepth
    • -
  • Bandwidth: 1024 KB blocks and 128 iodepth
    • -
-

For more details, see the fio test configuration.

-

The results for IOPS on Azure are as follows:

-

I/O IOPS Azure benchmark graph

-

The results for IOPS on GCP are as follows:

-

-

The results for bandwidth on Azure are as follows:

-

I/O bandwidth Azure benchmark graph

-

The results for bandwidth on GCP are as follows:

-

I/O bandwidth GCP benchmark graph

-

On GCP, the results exceed the maximum performance guarantees of the chosen disk type. There are two possible explanations for this. The first is that there may be cloud caching in place that isn't configurable. Alternatively, the underlying provisioned disk size may be larger than what was requested, resulting in higher performance boundaries.

-

When comparing Constellation on GCP with GKE, Constellation has similar bandwidth but about 10% less IOPS performance. On Azure, Constellation has similar IOPS performance compared to AKS, where both likely hit the maximum storage performance. However, Constellation has approximately 15% less read and write bandwidth.

-

Conclusion​

-

Despite the added security benefits that Constellation provides, it only incurs a slight performance overhead when compared to managed Kubernetes offerings such as AKS and GKE. In most compute benchmarks, Constellation is on par with it's alternatives. -While it may be slightly slower in certain I/O scenarios due to network and storage encryption, there is ongoing work to reduce this overhead to single digits.

-

For instance, storage encryption only adds between 10% to 15% overhead in terms of bandwidth and IOPS. -Meanwhile, the biggest performance impact that Constellation currently faces is network encryption, which can incur up to 58% overhead on a 10 Gbps network. -However, the Cilium team has conducted benchmarks with Cilium using WireGuard encryption on a 100 Gbps network that yielded over 15 Gbps. -We're confident that Constellation will provide a similar level of performance with an upcoming release.

-

Overall, Constellation strikes a great balance between security and performance, and we're continuously working to improve its performance capabilities while maintaining its high level of security.

Product features

-

Constellation is a Kubernetes engine that aims to provide the best possible data security in combination with enterprise-grade scalability and reliability features---and a smooth user experience.

-

From a security perspective, Constellation implements the Confidential Kubernetes concept and corresponding security features, which shield your entire cluster from the underlying infrastructure.

-

From an operational perspective, Constellation provides the following key features:

-
    -
  • Native support for different clouds: Constellation works on Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and STACKIT. Support for OpenStack-based environments is coming with a future release. Constellation securely interfaces with the cloud infrastructure to provide cluster autoscaling, dynamic persistent volumes, and service load balancing.
    • -
  • High availability: Constellation uses a multi-master architecture with a stacked etcd topology to ensure high availability.
    • -
  • Integrated Day-2 operations: Constellation lets you securely upgrade your cluster to a new release. It also lets you securely recover a failed cluster. Both with a single command.
    • -
  • Support for Terraform: Constellation includes a Terraform provider that lets you manage the full lifecycle of your cluster via Terraform.

Security benefits and threat model

-

Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

-

TCB comparison

-

Given this background, the following describes the concrete threat classes that Constellation addresses.

-

Insider access​

-

Employees and third-party contractors of cloud service providers (CSPs) have access to different layers of the cloud infrastructure. -This opens up a large attack surface where workloads and data can be read, copied, or manipulated. With Constellation, Kubernetes deployments are shielded from the infrastructure and thus such accesses are prevented.

-

Infrastructure-based attacks​

-

Malicious cloud users ("hackers") may break out of their tenancy and access other tenants' data. Advanced attackers may even be able to establish a permanent foothold within the infrastructure and access data over a longer period. Analogously to the insider access scenario, Constellation also prevents access to a deployment's data in this scenario.

-

Supply chain attacks​

-

Supply chain security is receiving lots of attention recently due to an increasing number of recorded attacks. For instance, a malicious actor could attempt to tamper Constellation node images (including Kubernetes and other software) before they're loaded in the confidential VMs of a cluster. Constellation uses remote attestation in conjunction with public transparency logs to prevent this.

-

In the future, Constellation will extend this feature to customer workloads. This will enable cluster owners to create auditable policies that precisely define which containers can run in a given deployment.

-

This document describes breaking changes and migrations between Constellation releases. -Use constellation config migrate to automatically update an old config file to a new format.

-

Migrations to v2.23.0​

-

GCP​

-

GCP will require the additional permission compute.forwardingRules.list. Please update your IAM roles using constellation iam upgrade apply.

-

Migrations to v2.19.1​

-

Azure​

-
    -
  • During the upgrade, security rules are migrated and the old ones need to be cleaned up manually by the user. The below script shows how to delete them through the Azure CLI:

Migrating from CLI versions before 2.21.1​

-

AWS​

-
    -
  • AWS clusters that use LoadBalancer resources require more IAM permissions. Please upgrade your IAM roles using constellation iam upgrade apply. This will show necessary changes and apply them, if desired.
    • -
-

Migrating from CLI versions before 2.19.0​

-

Azure​

-
    -
  • To allow seamless upgrades on Azure when Kubernetes services of type LoadBalancer are deployed, the target -load balancer in which the cloud-controller-manager creates load balancing rules was changed. Instead of using the load balancer -created and maintained by the CLI's Terraform code, the cloud-controller-manager now creates its own load balancer in Azure. -If your Constellation has services of type LoadBalancer, please remove them before the upgrade and re-apply them -afterward.
    • -
-

Migrating from CLI versions before 2.18.0​

-
    -
  • The provider.azure.appClientID and provider.azure.appClientSecret fields are no longer supported and should be removed.
    • -
  • To keep using an existing UAMI, add the Owner permission with the scope of your resourceGroup.
    • -
  • Otherwise, simply create new Constellation IAM credentials and use the created UAMI.
    • -
  • To migrate the authentication for an existing cluster on Azure to an UAMI with the necessary permissions: -
      -
    1. Remove the aadClientId and aadClientSecret from the azureconfig secret.
      2. -
    2. Set useManagedIdentityExtension to true and use the userAssignedIdentity from the Constellation config for the value of userAssignedIdentityID.
      3. -
    3. Restart the CSI driver, cloud controller manager, cluster autoscaler, and Constellation operator pods.
      4. -
    -
    • -
-

Migrating from CLI versions before 2.10​

-
    -
  • AWS cluster upgrades require additional IAM permissions for the newly introduced aws-load-balancer-controller. Please upgrade your IAM roles using iam upgrade apply. This will show necessary changes and apply them, if desired.
    • -
  • The global nodeGroups field was added.
    • -
  • The fields instanceType, stateDiskSizeGB, and stateDiskType for each cloud provider are now part of the configuration of individual node groups.
    • -
  • The constellation create command no longer uses the flags --control-plane-count and --worker-count. Instead, the initial node count is configured per node group in the nodeGroups field.
    • -
-

Migrating from CLI versions before 2.9​

-
    -
  • The provider.azure.appClientID and provider.azure.clientSecretValue fields were removed to enforce migration to managed identity authentication

Supply chain levels for software artifacts (SLSA) adoption

-

Supply chain Levels for Software Artifacts, or SLSA (salsa) is a framework for improving and grading a project's build system and engineering processes. SLSA focuses on security improvements for source code storage as well as build system definition, execution, and observation. SLSA is structured in four levels. This page describes the adoption of SLSA for Constellation.

-
info

SLSA is still in alpha status. The presented levels and their requirements might change in the future. We will adopt any changes into our engineering processes, as they get defined.

-

Level 1 - Adopted​

-

Build - Scripted

-

All build steps are automated via Bazel and GitHub Actions.

-

Provenance - Available

-

Provenance for the CLI is generated using the slsa-github-generator.

-

Level 2 - Adopted​

-

Source - Version Controlled

-

Constellation is hosted on GitHub using git.

-

Build - Build Service

-

All builds are carried out by GitHub Actions.

-

Provenance - Authenticated

-

Provenance for the CLI is signed using the slsa-github-generator. Learn how to verify the CLI using the signed provenance, before using it for the first time.

-

Provenance - Service Generated

-

Provenance for the CLI is generated using the slsa-github-generator in GitHub Actions.

-

Level 3 - Adopted​

-

Source - Verified History

-

The Edgeless Systems GitHub organization requires two-factor authentication for all members.

-

Source - Retained Indefinitely

-

Since we use GitHub to host the repository, an external person can't modify or delete the history. Before a pull request can be merged, an explicit approval from an Edgeless Systems team member is required.

-

The same holds true for changes proposed by team members. Each change to main needs to be proposed via a pull request and requires at least one approval.

-

The Edgeless Systems GitHub organization admins control these settings and are able to make changes to the repository's history should legal requirements necessitate it. These changes require two-party approval following the obliterate policy.

-

Build - Build as Code

-

All build files for Constellation are stored in the same repository.

-

Build - Ephemeral Environment

-

All GitHub Action workflows are executed on GitHub-hosted runners. These runners are only available during workflow.

-

We currently don't use self-hosted runners.

-

Build - Isolated

-

As outlined in the previous section, we use GitHub-hosted runners, which provide a new, isolated and ephemeral environment for each build.

-

Additionally, the SLSA GitHub generator itself is run in an isolated workflow with the artifact hash as defined inputs.

-

Provenance - Non-falsifiable

-

As outlined by SLSA GitHub generator it already fulfills the non-falsifiable requirements for SLSA Level 3. The generated provenance is signed using sigstore with an OIDC based proof of identity.

-

Level 4 - In Progress​

-

We strive to adopt certain aspect of SLSA Level 4 that support our engineering process. At the same time, SLSA is still in alpha status and the biggest changes to SLSA are expected to be around Level 4.

Version: 2.23

Terraform usage

-

Terraform is an Infrastructure as Code (IaC) framework to manage cloud resources. This page explains how Constellation uses it internally and how advanced users may manually use it to have more control over the resource creation.

-
info

Information on this page is intended for users who are familiar with Terraform. -It's not required for common usage of Constellation. -See the Terraform documentation if you want to learn more about it.

-

Terraform state files​

-

Constellation keeps Terraform state files in subdirectories of the workspace together with the corresponding Terraform configuration files and metadata. -The subdirectories are created on the first Constellation CLI action that uses Terraform internally.

-

Currently, these subdirectories are:

-
    -
  • constellation-terraform - Terraform state files for the resources of the Constellation cluster
    • -
  • constellation-iam-terraform - Terraform state files for IAM configuration
    • -
-

As with all commands, commands that work with these files (e.g., apply, terminate, iam) have to be executed from the root of the cluster's workspace directory. You usually don't need and shouldn't manipulate or delete the subdirectories manually.

-

Interacting with Terraform manually​

-

Manual interaction with Terraform state created by Constellation (i.e., via the Terraform CLI) should only be performed by experienced users. It may lead to unrecoverable loss of cloud resources. For the majority of users and use cases, the interaction done by the Constellation CLI is sufficient.

-

Terraform debugging​

-

To debug Terraform issues, the Constellation CLI offers the tf-log flag. You can set it to any of Terraform's log levels:

-
    -
  • JSON (JSON-formatted logs at TRACE level)
    • -
  • TRACE
    • -
  • DEBUG
    • -
  • INFO
    • -
  • WARN
    • -
  • ERROR
    • -
-

The log output is written to the terraform.log file in the workspace directory. The output is appended to the file on each run.

Install cert-manager

-
caution

If you want to use cert-manager with Constellation, pay attention to the following to avoid potential pitfalls.

-

Constellation ships with cert-manager preinstalled. -The default installation is part of the kube-system namespace, as all other Constellation-managed microservices. -You are free to install more instances of cert-manager into other namespaces. -However, be aware that any new installation needs to use the same version as the one installed with Constellation or rely on the same CRD versions. -Also remember to set the installCRDs value to false when installing new cert-manager instances. -It will create problems if you have two installations of cert-manager depending on different versions of the installed CRDs. -CRDs are cluster-wide resources and cert-manager depends on specific versions of those CRDs for each release.

Before you can create your cluster, you need to configure the identity and access management (IAM) for your cloud service provider (CSP) and choose machine types for the nodes.

-

Creating the configuration file​

-

You can generate a configuration file for your CSP by using the following CLI command:

-
constellation config generate aws
-

This creates the file constellation-conf.yaml in the current directory.

-

Choosing a VM type​

Constellation supports the following VM types:

By default, Constellation uses m6a.xlarge VMs (4 vCPUs, 16 GB RAM) to create your cluster. -Optionally, you can switch to a different VM type by modifying instanceType in the configuration file. -If you are using the default attestation variant awsSEVSNP, you can use the instance types described in AWS's AMD SEV-SNP docs. -Please mind the region restrictions mentioned in the Getting started section.

If you are using the attestation variant awsNitroTPM, you can choose any of the nitroTPM-enabled instance types.

The Constellation CLI can also print the supported instance types with: constellation config instance-types.

-

Fill the desired VM type into the instanceType fields in the constellation-conf.yml file.

-

Creating additional node groups​

-

By default, Constellation creates the node groups control_plane_default and worker_default for control-plane nodes and workers, respectively. -If you require additional control-plane or worker groups with different instance types, zone placements, or disk sizes, you can add additional node groups to the constellation-conf.yml file. -Each node group can be scaled individually.

-

Consider the following example for AWS:

-
nodeGroups:
  control_plane_default:
    role: control-plane
    instanceType: c6a.xlarge
    stateDiskSizeGB: 30
    stateDiskType: gp3
    zone: eu-west-1c
    initialCount: 3
  worker_default:
    role: worker
    instanceType: c6a.xlarge
    stateDiskSizeGB: 30
    stateDiskType: gp3
    zone: eu-west-1c
    initialCount: 2
  high_cpu:
    role: worker
    instanceType: c6a.24xlarge
    stateDiskSizeGB: 128
    stateDiskType: gp3
    zone: eu-west-1c
    initialCount: 1
-

This configuration creates an additional node group high_cpu with a larger instance type and disk.

-

You can use the field zone to specify what availability zone nodes of the group are placed in. -On Azure, this field is empty by default and nodes are automatically spread across availability zones. -STACKIT currently offers SEV-enabled CPUs in the eu01-1, eu01-2, and eu01-3 zones. -Consult the documentation of your cloud provider for more information:

- -

Choosing a Kubernetes version​

-

To learn which Kubernetes versions can be installed with your current CLI, you can run constellation config kubernetes-versions. -See also Constellation's Kubernetes support policy.

-

Creating an IAM configuration​

-

You can create an IAM configuration for your cluster automatically using the constellation iam create command. -If you already have a Constellation configuration file, you can add the --update-config flag to the command. This writes the needed IAM fields into your configuration. Furthermore, the flag updates the zone/region of the configuration if it hasn't been set yet.

-

You must be authenticated with the AWS CLI in the shell session with a user that has the required permissions for IAM creation.

constellation iam create aws --zone=us-east-2a --prefix=constellTest

This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created.

Constellation OS images are currently replicated to the following regions:

    -
  • eu-central-1
    • -
  • eu-west-1
    • -
  • eu-west-3
    • -
  • us-east-2
    • -
  • ap-south-1
    • -

If you require the OS image to be available in another region, let us know.

You can find a list of all regions in AWS's documentation.

Paste the output into the corresponding fields of the constellation-conf.yaml file.

-
Alternatively, you can manually create the IAM configuration on your CSP.

The following describes the configuration fields and how you obtain the required information or create the required resources.

    -
  • -

    region: The name of your chosen AWS data center region, e.g., us-east-2.

    -

    Learn more about availability zones in AWS's documentation.

    -
    • -
  • -

    iamProfileControlPlane: The name of an IAM instance profile attached to all control-plane nodes.

    -

    You can create the resource with Terraform. For that, use the provided Terraform script to generate the necessary profile. The profile name will be provided as Terraform output value: control_plane_instance_profile_name.

    -

    Alternatively, you can create the AWS profile with a tool of your choice. Use the JSON policy in main.tf in the resource aws_iam_policy.control_plane_policy.

    -
    • -
  • -

    iamProfileWorkerNodes: The name of an IAM instance profile attached to all worker nodes.

    -

    You can create the resource with Terraform. For that, use the provided Terraform script to generate the necessary profile. The profile name will be provided as Terraform output value: worker_nodes_instance_profile_name.

    -

    Alternatively, you can create the AWS profile with a tool of your choice. Use the JSON policy in main.tf in the resource aws_iam_policy.worker_node_policy.

    -
    • -
-

Now that you've configured your CSP, you can create your cluster.

-

Deleting an IAM configuration​

-

You can keep a created IAM configuration and reuse it for new clusters. Alternatively, you can also delete it if you don't want to use it anymore.

-

Delete the IAM configuration by executing the following command in the same directory where you executed constellation iam create (the directory that contains constellation-iam-terraform as a subdirectory):

-
constellation iam destroy
-
caution

For Azure, deleting the IAM configuration by executing constellation iam destroy will delete the whole resource group created by constellation iam create. -This also includes any additional resources in the resource group that weren't created by Constellation.

-
-

Creating your cluster happens through multiple phases. -The most significant ones are:

-
    -
  1. Creating the necessary resources in your cloud environment
    2. -
  2. Bootstrapping the Constellation cluster and setting up a connection
    3. -
  3. Installing the necessary Kubernetes components
    4. -
-

constellation apply handles all this in a single command. -You can use the --skip-phases flag to skip specific phases of the process. -For example, if you created the infrastructure manually, you can skip the cloud resource creation phase.

-

See the architecture section for details on the inner workings of this process.

-
tip

If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

-

Before you create the cluster, make sure to have a valid configuration file.

-
constellation apply

apply stores the state of your cluster's cloud resources in a constellation-terraform directory in your workspace.

-

Finally, configure kubectl for your cluster:

-
export KUBECONFIG="$PWD/constellation-admin.conf"
-

🏁 That's it. You've successfully created a Constellation cluster.

-

Troubleshooting​

-

In case apply fails, the CLI collects logs from the bootstrapping instance and stores them inside constellation-cluster.log.

Expose a service

-

Constellation integrates the native load balancers of each CSP. Therefore, to expose a service simply create a service of type LoadBalancer.

-

Internet-facing LB service on AWS​

-

To expose your application service externally you might want to use a Kubernetes Service of type LoadBalancer. On AWS, load-balancing is achieved through the AWS Load Balancer Controller as in the managed EKS.

-

Since recent versions, the controller deploy an internal LB by default requiring to set an annotation service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing to have an internet-facing LB. For more details, see the official docs.

-

For general information on LB with AWS see Network load balancing on Amazon EKS.

-
caution

Before terminating the cluster, all LB backed services should be deleted, so that the controller can cleanup the related resources.

-

Ingress on AWS​

-

The AWS Load Balancer Controller also provisions Ingress resources of class alb. -AWS Application Load Balancers (ALBs) can be configured with a target-type. -The target type ip requires using the EKS container network solution, which makes it incompatible with Constellation. -If a service can be exposed on a NodePort, the target type instance can be used.

-

See Application load balancing on Amazon EKS for more information.

-
caution

Ingress handlers backed by AWS ALBs reside outside the Constellation cluster, so they shouldn't be handling sensitive traffic!

Version: 2.23

Recover your cluster

-

Recovery of a Constellation cluster means getting it back into a healthy state after too many concurrent node failures in the control plane. -Reasons for an unhealthy cluster can vary from a power outage, or planned reboot, to migration of nodes and regions. -Recovery events are rare, because Constellation is built for high availability and automatically and securely replaces failed nodes. When a node is replaced, Constellation's control plane first verifies the new node before it sends the node the cryptographic keys required to decrypt its state disk.

-

Constellation provides a recovery mechanism for cases where the control plane has failed and is unable to replace nodes. -The constellation recover command securely connects to all nodes in need of recovery using attested TLS and provides them with the keys to decrypt their state disks and continue booting.

-

Identify unhealthy clusters​

-

The first step to recovery is identifying when a cluster becomes unhealthy. -Usually, this can be first observed when the Kubernetes API server becomes unresponsive.

-

You can check the health status of the nodes via the cloud service provider (CSP). -Constellation provides logging information on the boot process and status via serial console output. -In the following, you'll find detailed descriptions for identifying clusters stuck in recovery for each CSP.

-

First, open the AWS console to view all Auto Scaling Groups (ASGs) in the region of your cluster. Select the ASG of the control plane <cluster-name>-<UID>-control-plane and check that enough members are in a Running state.

Second, check the boot logs of these Instances. In the ASG's Instance management view, select each desired instance. In the upper right corner, select Action > Monitor and troubleshoot > Get system log.

In the serial console output, search for Waiting for decryption key. -Similar output to the following means your node was restarted and needs to decrypt the state disk:

{"level":"INFO","ts":"2022-09-08T10:21:53Z","caller":"cmd/main.go:55","msg":"Starting disk-mapper","version":"2.0.0","cloudProvider":"gcp"}

{"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"recoveryServer","caller":"recoveryserver/server.go:59","msg":"Starting RecoveryServer"}

The node will then try to connect to the JoinService and obtain the decryption key. -If this fails due to an unhealthy control plane, you will see log messages similar to the following:

This means that you have to recover the node manually.

-

Recover a cluster​

-

Recovering a cluster requires the following parameters:

-
    -
  • The constellation-state.yaml file in your working directory or the cluster's endpoint
    • -
  • The master secret of the cluster
    • -
-

A cluster can be recovered like this:

-
$ constellation recover

Reproduce released artifacts

-

Constellation has first-class support for reproducible builds. -Reproducing the released artifacts is an alternative to signature verification that doesn't require trusting Edgeless Systems' release process. -The following sections describe how to rebuild an artifact and how Constellation ensures that the rebuild reproduces the artifacts bit-by-bit.

-

Build environment prerequisites​

-

The build systems used by Constellation - Bazel and Nix - are designed for deterministic, reproducible builds. -These two dependencies should be the only prerequisites for a successful build. -However, it can't be ruled out completely that peculiarities of the host affect the build result. -Thus, we recommend the following host setup for best results:

-
    -
  1. A Linux operating system not older than v5.4.
    2. -
  2. The GNU C library not older than v2.31 (avoid musl).
    3. -
  3. GNU coreutils not older than v8.30 (avoid busybox).
    4. -
  4. An ext4 filesystem for building.
    5. -
  5. AppArmor turned off.
    6. -
-

This is given, for example, on an Ubuntu 22.04 system, which is also used for reproducibility tests.

-
note

To avoid any backwards-compatibility issues, the host software versions should also not be much newer than the Constellation release.

-

Run the build​

-

The following instructions outline qualitatively how to reproduce a build. -Constellation implements these instructions in the Reproducible Builds workflow, which continuously tests for reproducibility. -The workflow is a good place to look up specific version numbers and build steps.

-
    -
  1. -

    Check out the Constellation repository at the tag corresponding to the release.

    -
    git clone https://github.com/edgelesssys/constellation.git
    cd constellation
    git checkout v2.20.0
    -
    2. -
  2. -

    Install the Bazel release specified in .bazelversion.

    -
    3. -
  3. -

    Install Nix (any recent version should do).

    -
    4. -

Feedback​

-

Reproduction failures often indicate a bug in the build system or in the build definitions. -Therefore, we're interested in any reproducibility issues you might encounter. -Start a bug report and describe the details of your build environment. -Make sure to include your result binary or a diffoscope report, if possible.

Install s3proxy

-

Constellation includes a transparent client-side encryption proxy for AWS S3 and compatible stores. -s3proxy encrypts objects before sending them to S3 and automatically decrypts them on retrieval, without requiring changes to your application. -With s3proxy, you can use S3 for storage in a confidential way without having to trust the storage provider.

-

Limitations​

-

Currently, s3proxy has the following limitations:

-
    -
  • Only PutObject and GetObject requests are encrypted/decrypted by s3proxy. -By default, s3proxy will block requests that may expose unencrypted data to S3 (e.g. UploadPart). -The allow-multipart flag disables request blocking for evaluation purposes.
    • -
  • Using the Range header on GetObject is currently not supported and will result in an error.
    • -
-

These limitations will be removed with future iterations of s3proxy. -If you want to use s3proxy but these limitations stop you from doing so, consider opening an issue.

-

Deployment​

-

You can add the s3proxy to your Constellation cluster as follows:

-
    -
  1. Add the Edgeless Systems chart repository: -
    helm repo add edgeless https://helm.edgeless.systems/stable
    helm repo update
    -
    2. -
  2. Set ACCESS_KEY and ACCESS_SECRET to valid credentials you want s3proxy to use to interact with S3.
    3. -
  3. Deploy s3proxy: -
    helm install s3proxy edgeless/s3proxy --set awsAccessKeyID="$ACCESS_KEY" --set awsSecretAccessKey="$ACCESS_SECRET"
    -
    4. -
-

If you want to run a demo application, check out the Filestash with s3proxy example.

-

Technical details​

-

Encryption​

-

s3proxy relies on Google's Tink Cryptographic Library to implement cryptographic operations securely. -The used cryptographic primitives are NIST SP 800 38f for key wrapping and AES-GCM with 256 bit keys for data encryption.

-

s3proxy uses envelope encryption to encrypt objects. -This means s3proxy uses a key encryption key (KEK) issued by the KeyService to encrypt data encryption keys (DEKs). -Each S3 object is encrypted with its own DEK. -The encrypted DEK is then saved as metadata of the encrypted object. -This enables key rotation of the KEK without re-encrypting the data in S3. -The approach also allows access to objects from different locations, as long as each location has access to the KEK.

-

Traffic interception​

-

To use s3proxy, you have to redirect your outbound S3 traffic to s3proxy. -This can either be done by modifying your client application or by changing the deployment of your application.

-

The necessary deployment modifications are to add DNS redirection and a trusted TLS certificate to the client's trust store. -DNS redirection can be defined for each pod, allowing you to use s3proxy for one application without changing other applications in the same cluster. -Adding a trusted TLS certificate is necessary as clients communicate with s3proxy via HTTPS. -To have your client application trust s3proxy's TLS certificate, the certificate has to be added to the client's certificate trust store. -The Filestash with s3proxy example shows how to do this.

-
Loading asciinema cast...
-
-

Constellation builds produce a software bill of materials (SBOM) for each generated artifact. -You can use SBOMs to make informed decisions about dependencies and vulnerabilities in a given application. Enterprises rely on SBOMs to maintain an inventory of used applications, which allows them to take data-driven approaches to managing risks related to vulnerabilities.

-

SBOMs for Constellation are generated using Syft, signed using Cosign, and stored with the produced artifact.

-
note

The public key for Edgeless Systems' long-term code-signing key is:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEf8F1hpmwE+YCFXzjGtaQcrL6XZVT
JmEe5iSLvG1SyQSAew7WdMKF6o9t8e2TFuCkzlOhhlws2OHWbiFZnFWCFw==
-----END PUBLIC KEY-----

The public key is also available for download at https://edgeless.systems/es.pub and in the Twitter profile @EdgelessSystems.

Make sure the key is available in a file named cosign.pub to execute the following examples.

-

Verify and download SBOMs​

-

The following sections detail how to work with each type of artifact to verify and extract the SBOM.

-

Constellation CLI​

-

The SBOM for Constellation CLI is made available on the GitHub release page. The SBOM (constellation.spdx.sbom) and corresponding signature (constellation.spdx.sbom.sig) are valid for each Constellation CLI for a given version, regardless of architecture and operating system.

-
curl -LO https://github.com/edgelesssys/constellation/releases/download/v2.2.0/constellation.spdx.sbom
curl -LO https://github.com/edgelesssys/constellation/releases/download/v2.2.0/constellation.spdx.sbom.sig
cosign verify-blob --key cosign.pub --signature constellation.spdx.sbom.sig constellation.spdx.sbom
-

Container Images​

-

SBOMs for container images are attached to the image using Cosign and uploaded to the same registry.

-

As a consumer, use cosign to download and verify the SBOM:

-
# Verify and download the attestation statement
cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.att.json
# Extract SBOM from attestation statement
jq -r .payload verification-service.att.json | base64 -d > verification-service.cyclonedx.sbom
-

A successful verification should result in similar output:

-
$ cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.sbom

Verification for ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --
The following checks were performed on each of these signatures:
  - The cosign claims were validated
  - The signatures were verified against the specified public key
$ jq -r .payload verification-service.sbom | base64 -d > verification-service.cyclonedx.sbom
-
note

This example considers only the verification-service. The same approach works for all containers in the Constellation container registry.

-

Vulnerability scanning​

-

You can use a plethora of tools to consume SBOMs. This section provides suggestions for tools that are popular and known to produce reliable results, but any tool that consumes SPDX or CycloneDX files should work.

-

Syft is able to convert between the two formats in case you require a specific type.

-

Grype​

-

Grype is a CLI tool that lends itself well for integration into CI/CD systems or local developer machines. It's also able to consume the signed attestation statement directly and does the verification in one go.

-
grype att:verification-service.sbom --key cosign.pub --add-cpes-if-none -q
-

Dependency Track​

-

Version: 2.23

Scale your cluster

-

Constellation provides all features of a Kubernetes cluster including scaling and autoscaling.

-

Worker node scaling​

-

Autoscaling​

-

Constellation comes with autoscaling disabled by default. To enable autoscaling, find the scaling group of -worker nodes:

-
kubectl get scalinggroups -o json | yq '.items | .[] | select(.spec.role == "Worker") | [{"name": .metadata.name, "nodeGoupName": .spec.nodeGroupName}]'
-

This will output a list of scaling groups with the corresponding cloud provider name (name) and the cloud provider agnostic name of the node group (nodeGroupName).

-

Then, patch the autoscaling field of the scaling group resource with the desired name to true:

-
# Replace <name> with the name of the scaling group you want to enable autoscaling for
worker_group=<name>
kubectl patch scalinggroups $worker_group --patch '{"spec":{"autoscaling": true}}' --type='merge'
kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
-

The cluster autoscaler now automatically provisions additional worker nodes so that all pods have a place to run. -You can configure the minimum and maximum number of worker nodes in the scaling group by patching the min or -max fields of the scaling group resource:

-
kubectl patch scalinggroups $worker_group --patch '{"spec":{"max": 5}}' --type='merge'
kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
-

The cluster autoscaler will now never provision more than 5 worker nodes.

-

If you want to see the autoscaling in action, try to add a deployment with a lot of replicas, like the -following Nginx deployment. The number of replicas needed to trigger the autoscaling depends on the size of -and count of your worker nodes. Wait for the rollout of the deployment to finish and compare the number of -worker nodes before and after the deployment:

-
kubectl create deployment nginx --image=nginx --replicas 150
kubectl -n kube-system get nodes
kubectl rollout status deployment nginx
kubectl -n kube-system get nodes
-

Manual scaling​

-

Alternatively, you can manually scale your cluster up or down:

-
    -
  1. Go to Auto Scaling Groups and select the worker ASG to scale up.
    2. -
  2. Click Edit
    3. -
  3. Set the new (increased) Desired capacity and Update.
    4. -
-

Control-plane node scaling​

-

Control-plane nodes can only be scaled manually and only scaled up!

-

To increase the number of control-plane nodes, follow these steps:

-
    -
  1. Go to Auto Scaling Groups and select the control-plane ASG to scale up.
    2. -
  2. Click Edit
    3. -
  3. Set the new (increased) Desired capacity and Update.
    4. -
-

If you scale down the number of control-planes nodes, the removed nodes won't be able to exit the etcd cluster correctly. This will endanger the quorum that's required to run a stable Kubernetes control plane.

Version: 2.23

Use persistent storage

-

Persistent storage in Kubernetes requires cloud-specific configuration. -For abstraction of container storage, Kubernetes offers volumes, -allowing users to mount storage solutions directly into containers. -The Container Storage Interface (CSI) is the standard interface for exposing arbitrary block and file storage systems into containers in Kubernetes. -Cloud service providers (CSPs) offer their own CSI-based solutions for cloud storage.

-

Confidential storage​

-

Most cloud storage solutions support encryption, such as GCE Persistent Disks (PD). -Constellation supports the available CSI-based storage options for Kubernetes engines in AWS, Azure, GCP, and STACKIT. -However, their encryption takes place in the storage backend and is managed by the CSP. -Thus, using the default CSI drivers for these storage types means trusting the CSP with your persistent data.

-

To address this, Constellation provides CSI drivers for AWS EBS, Azure Disk, GCE PD, and OpenStack Cinder, offering encryption on the node level. They enable transparent encryption for persistent volumes without needing to trust the cloud backend. Plaintext data never leaves the confidential VM context, offering you confidential storage.

-

For more details see encrypted persistent storage.

-

CSI drivers​

-

Constellation supports the following drivers, which offer node-level encryption and optional integrity protection.

-

Constellation CSI driver for AWS Elastic Block Store -Mount Elastic Block Store storage volumes into your Constellation cluster. -Follow the instructions on how to install the Constellation CSI driver or check out the repository for more information.

-

Note that in case the options above aren't a suitable solution for you, Constellation is compatible with all other CSI-based storage options. For example, you can use AWS EFS, Azure Files, or GCP Filestore with Constellation out of the box. Constellation is just not providing transparent encryption on the node level for these storage types yet.

-

Installation​

-

The Constellation CLI automatically installs Constellation's CSI driver for the selected CSP in your cluster. -If you don't need a CSI driver or wish to deploy your own, you can disable the automatic installation by setting deployCSIDriver to false in your Constellation config file.

-

AWS comes with two storage classes by default.

    -
  • encrypted-rwo -
      -
    • Uses SSDs of gp3 type
      • -
    • ext-4 filesystem
      • -
    • Encryption of all data written to disk
      • -
    -
    • -
  • integrity-encrypted-rwo -

      • -
    • Integrity protection of data written to disk
      • -
    -
    • -

For more information on encryption algorithms and key sizes, refer to cryptographic algorithms.

info

The default storage class is set to encrypted-rwo for performance reasons. -If you want integrity-protected storage, set the storageClassName parameter of your persistent volume claim to integrity-encrypted-rwo.

Alternatively, you can create your own storage class with integrity protection enabled by adding csi.storage.k8s.io/fstype: ext4-integrity to the class parameters. -Or use another filesystem by specifying another file system type with the suffix -integrity, e.g., csi.storage.k8s.io/fstype: xfs-integrity.

Note that volume expansion isn't supported for integrity-protected disks.

-
    -
  1. -

    Create a persistent volume

    -

    A persistent volume claim is a request for storage with certain properties. -It can refer to a storage class. -The following creates a persistent volume claim, requesting 20 GB of storage via the encrypted-rwo storage class:

    -
    cat <<EOF | kubectl apply -f -
    kind: PersistentVolumeClaim
    apiVersion: v1
    metadata:
      name: pvc-example
      namespace: default
    spec:
      accessModes:
      - ReadWriteOnce
      storageClassName: encrypted-rwo
      resources:
        requests:
          storage: 20Gi
    EOF
    -
    2. -
  2. -

    Create a Pod with persistent storage

    -

    You can assign a persistent volume claim to an application in need of persistent storage. -The mounted volume will persist restarts. -The following creates a pod that uses the previously created persistent volume claim:

    -
    cat <<EOF | kubectl apply -f -
    apiVersion: v1
    kind: Pod
    metadata:
      name: web-server
      namespace: default
    spec:
      containers:
      - name: web-server
        image: nginx
        volumeMounts:
        - mountPath: /var/lib/www/html
          name: mypvc
      volumes:
      - name: mypvc
        persistentVolumeClaim:
          claimName: pvc-example
          readOnly: false
    EOF
    -
    3. -
-

Change the default storage class​

-

The default storage class is responsible for all persistent volume claims that don't explicitly request storageClassName. -Constellation creates a storage class with encryption enabled and sets this as the default class. -In case you wish to change it, follow the steps below:

-
    -
  1. -

    List the storage classes in your cluster:

    -
    kubectl get storageclass
    -

    The output is similar to this:

    -
    NAME                      PROVISIONER                         RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
    encrypted-rwo (default)   {your-csp}.csi.confidential.cloud   Delete          Immediate           true                   1d
    integrity-encrypted-rwo   {your-csp}.csi.confidential.cloud   Delete          Immediate           false                  1d
    -

    The default storage class is marked by (default).

    -
    2. -
  2. -

    Mark old default storage class as non default

    -

    If you previously used another storage class as the default, you will have to remove that annotation:

    -
    kubectl patch storageclass encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
    -
    3. -
  3. -

    Mark new class as the default

    -
    kubectl patch storageclass integrity-encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
    -
    4. -
  4. -

    Verify that your chosen storage class is default:

    -
    kubectl get storageclass
    -

    The output is similar to this:

    -
    NAME                                PROVISIONER                         RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
    encrypted-rwo                       {your-csp}.csi.confidential.cloud   Delete          Immediate           true                   1d
    integrity-encrypted-rwo (default)   {your-csp}.csi.confidential.cloud   Delete          Immediate           false                  1d

Terminate your cluster

-
info

This recording presents the essence of this page. It's recommended to read it in full for the motivation and all details.

-
Loading asciinema cast...
-
-

You can terminate your cluster using the CLI. For this, you need the Terraform state directory named constellation-terraform in the current directory.

-
danger

All ephemeral storage and state of your cluster will be lost. Make sure any data is safely stored in persistent storage. Constellation can recreate your cluster and the associated encryption keys, but won't backup your application data automatically.

-

Terminate the cluster by running:

constellation terminate

Or without confirmation (e.g., for automation purposes):

constellation terminate --yes

This deletes all resources created by Constellation in your cloud environment. -All local files created by the apply command are deleted as well, except for constellation-mastersecret.json and the configuration file.

caution

Termination can fail if additional resources have been created that depend on the ones managed by Constellation. In this case, you need to delete these additional -resources manually. Just run the terminate command again afterward to continue the termination process of the cluster.

Version: 2.23

Use the Terraform provider

-

The Constellation Terraform provider allows to manage the full lifecycle of a Constellation cluster (namely creation, upgrades, and deletion) via Terraform. -The provider is available through the Terraform registry and is released in lock-step with Constellation releases.

-

Prerequisites​

-
    -
  • a Linux / Mac operating system (ARM64/AMD64)
    • -
  • a Terraform installation of version v1.4.4 or above
    • -
-

Quick setup​

-

This example shows how to set up a Constellation cluster with the reference IAM and infrastructure setup. This setup is also used when creating a Constellation cluster through the Constellation CLI. You can either consume the IAM / infrastructure modules through a remote source (recommended) or local files. The latter requires downloading the infrastructure and IAM modules for the corresponding CSP from terraform-modules.zip on the Constellation release page and placing them in the Terraform workspace directory.

-
    -
  1. Create a directory (workspace) for your Constellation cluster.
    2. -
-
mkdir constellation-workspace
cd constellation-workspace
-
    -
  1. Use one of the example configurations for using the Constellation Terraform provider or create a main.tf file and fill it with the resources you want to create. The Constellation Terraform provider documentation offers thorough documentation on the resources and their attributes.
    2. -
  2. Initialize and apply the Terraform configuration.
    3. -
-

Initialize the providers and apply the configuration.

terraform init
terraform apply

Optionally, you can prefix the terraform apply command with TF_LOG=INFO to collect Terraform logs while applying the configuration. This may provide helpful output in debugging scenarios.

-
    -
  1. Connect to the cluster.
    2. -
-
terraform output -raw kubeconfig > constellation-admin.conf
export KUBECONFIG=$(realpath constellation-admin.conf)
-

Bringing your own infrastructure​

-

Instead of using the example infrastructure used in the quick setup, you can also provide your own infrastructure. -If you need a starting point for a custom infrastructure setup, you can download the infrastructure / IAM Terraform modules for the respective CSP from the Constellation GitHub releases. You can modify and extend the modules per your requirements, while keeping the basic functionality intact. -The module contains:

-
    -
  • {csp}: cloud resources the cluster runs on
    • -
  • iam/{csp}: IAM resources used within the cluster
    • -
-

When upgrading your cluster, make sure to check the Constellation release notes for potential breaking changes in the reference infrastructure / IAM modules that need to be considered.

-

Cluster upgrades​

-
tip

Also see the general documentation on cluster upgrades.

-

The steps for applying the upgrade are as follows:

-
    -
  1. Update the version constraint of the Constellation Terraform provider in the required_providers block in your Terraform configuration.
    2. -
  2. If you explicitly set any of the version attributes of the provider's resources and data sources (e.g. image_version or constellation_microservice_version), make sure to update them too. Refer to Constellation's version support policy for more information on how each Constellation version and its dependencies are supported.
    3. -
  3. Update the IAM / infrastructure configuration. - -
    4. -
  4. Upgrade the Terraform module and provider dependencies and apply the targeted configuration.

Troubleshooting

-

This section aids you in finding problems when working with Constellation.

-

Common issues​

-

Issues with creating new clusters​

-

When you create a new cluster, you should always use the latest release. -If something doesn't work, check out the known issues.

-

Azure: Resource Providers can't be registered​

-

On Azure, you may receive the following error when running apply or terminate with limited IAM permissions:

-
Error: Error ensuring Resource Providers are registered.

Terraform automatically attempts to register the Resource Providers it supports to
ensure it's able to provision resources.

If you don't have permission to register Resource Providers you may wish to use the
"skip_provider_registration" flag in the Provider block to disable this functionality.

[...]
-

To continue, please ensure that the required resource providers have been registered in your subscription by your administrator.

-

Afterward, set ARM_SKIP_PROVIDER_REGISTRATION=true as an environment variable and either run apply or terminate again. -For example:

-
ARM_SKIP_PROVIDER_REGISTRATION=true constellation apply
-

Or alternatively, for terminate:

-
ARM_SKIP_PROVIDER_REGISTRATION=true constellation terminate
-

Azure: Can't update attestation policy​

-

On Azure, you may receive the following error when running apply from within an Azure environment, e.g., an Azure VM:

-
An error occurred: patching policies: updating attestation policy: unexpected status code: 403 Forbidden
-

The problem occurs because the Azure SDK we use internally attempts to authenticate towards the Azure API with the managed identity of your current environment instead of the Azure CLI token.

-

We decided not to deviate from this behavior and comply with the ordering of credentials.

-

A solution is to add the required permissions to the managed identity of your environment. For example, the managed identity of your Azure VM, instead of the account that you've authenticated with in the Azure CLI.

-

If your setup requires a change in the ordering of credentials, please open an issue and explain your desired behavior.

-

Nodes fail to join with error untrusted measurement value​

-

This error indicates that a node's attestation statement contains measurements that don't match the trusted values expected by the JoinService. -This may for example happen if the cloud provider updates the VM's firmware such that it influences the runtime measurements in an unforeseen way. -A failed upgrade due to an erroneous attestation config can also cause this error. -You can change the expected measurements to resolve the failure.

-
caution

Attestation and trusted measurements are crucial for the security of your cluster. -Be extra careful when manually changing these settings. -When in doubt, check if the encountered issue is known or contact support.

-
tip

During an upgrade with modified attestation config, a backup of the current configuration is stored in the join-config config map in the kube-system namespace under the attestationConfig_backup key. To restore the old attestation config after a failed upgrade, replace the value of attestationConfig with the value from attestationConfig_backup:

kubectl patch configmaps -n kube-system join-config -p "{\"data\":{\"attestationConfig\":\"$(kubectl get configmaps -n kube-system join-config -o "jsonpath={.data.attestationConfig_backup}")\"}}"
-

You can use the apply command to change measurements of a running cluster:

-
    -
  1. Modify the measurements key in your local constellation-conf.yaml to the expected values.
    2. -
  2. Run constellation apply.
    3. -
-

Keep in mind that running apply also applies any version changes from your config to the cluster.

-

You can run these commands to learn about the versions currently configured in the cluster:

-
    -
  • Kubernetes API server version: kubectl get nodeversion constellation-version -o json -n kube-system | jq .spec.kubernetesClusterVersion
    • -
  • image version: kubectl get nodeversion constellation-version -o json -n kube-system | jq .spec.imageVersion
    • -
  • microservices versions: helm list --filter 'constellation-services' -n kube-system
    • -
-

Upgrading Kubernetes resources fails​

-

Constellation manages its Kubernetes resources using Helm. -When applying an upgrade, the charts that are about to be installed, and a values override file overrides.yaml, -are saved to disk in your current workspace under constellation-upgrade/upgrade-<timestamp>/helm-charts/. -If upgrading the charts using the Constellation CLI fails, you can review these charts and try to manually apply the upgrade.

-
caution

Changing and manually applying the charts may destroy cluster resources and can lead to broken Constellation deployments. -Proceed with caution and when in doubt, -check if the encountered issue is known or contact support.

-

Diagnosing issues​

-

Logs​

-

To get started on diagnosing issues with Constellation, it's often helpful to collect logs from nodes, pods, or other resources in the cluster. Most logs are available through Kubernetes' standard -logging interfaces.

-

To debug issues occurring at boot time of the nodes, you can use the serial console interface of the CSP while the machine boots to get a read-only view of the boot logs.

-

Apart from that, Constellation also offers further observability integrations.

-

Node shell access​

-

Debugging via a shell on a node is directly supported by Kubernetes.

-
    -
  1. -

    Figure out which node to connect to:

    -
    kubectl get nodes
    # or to see more information, such as IPs:
    kubectl get nodes -o wide
    -
    2. -
  2. -

    Connect to the node:

    -
    kubectl debug node/constell-worker-xksa0-000000 -it --image=busybox
    -

    You will be presented with a prompt.

    -

    The nodes file system is mounted at /host.

    -
    3. -
  3. -

    Once finished, clean up the debug pod:

    -
    kubectl delete pod node-debugger-constell-worker-xksa0-000000-bjthj
    -
    4. -
-

Emergency SSH access​

-

Emergency SSH access to nodes can be useful to diagnose issues or download important data even if the Kubernetes API isn't reachable anymore.

-
    -
  1. -

    Enter the constellation-terraform directory in your Constellation workspace and enable emergency SSH access to the cluster:

    -
     cd constellation-terraform
     echo "emergency_ssh = true" >> ./terraform.tfvars
     terraform apply
    -
    2. -
  2. -

    Sign an existing SSH key with your master secret:

    -
    cd ../ # go back to your Constellation workspace
    constellation ssh --key your_public_key.pub
    -

    A certificate is written to constellation_cert.pub.

    -

    The certificate is valid for 24 hours and enables you to access your Constellation nodes using -certificate based authentication.

    -
    3. -
  3. -

    Now you can connect to any Constellation node using your certificate and your private key.

    -
    ssh -o CertificateFile=constellation_cert.pub -i <your private key> root@<ip of constellation node>
    -

    Normally, you don't have access to the Constellation nodes since they reside in a private network. -To access those nodes anyways, you can use your Constellation load balancer as a proxy jump host. -For this, use something along the following SSH client configuration:

    -
    Host <LB domain name>
      ProxyJump none

    Host *
      IdentityFile <your private key>
      PreferredAuthentications publickey
      CertificateFile=constellation_cert.pub
      User root
      ProxyJump <LB domain name>
    -

    With this configuration you can connect to a Constellation node using ssh -F <this config> <private node IP>. -You can obtain the private node IP and the domain name of the load balancer using your CSP's web UI.

Version: 2.23

Use Azure trusted launch VMs

-

Constellation also supports trusted launch VMs on Microsoft Azure. Trusted launch VMs don't offer the same level of security as Confidential VMs, but are available in more regions and in larger quantities. The main difference between trusted launch VMs and normal VMs is that the former offer vTPM-based remote attestation. When used with trusted launch VMs, Constellation relies on vTPM-based remote attestation to verify nodes.

-
caution

Trusted launch VMs don't provide runtime encryption and don't keep the cloud service provider (CSP) out of your trusted computing base.

-

Constellation supports trusted launch VMs with instance types Standard_D*_v4 and Standard_E*_v4. Run constellation config instance-types for a list of all supported instance types.

-

VM images​

-

Azure currently doesn't support community galleries for trusted launch VMs. Thus, you need to manually import the Constellation node image into your cloud subscription.

-

The latest image is available at https://cdn.confidential.cloud/constellation/images/azure/trusted-launch/v2.2.0/constellation.img. Simply adjust the version number to download a newer version.

-

After you've downloaded the image, create a resource group constellation-images in your Azure subscription and import the image. -You can use a script to do this:

-
wget https://raw.githubusercontent.com/edgelesssys/constellation/main/hack/importAzure.sh
chmod +x importAzure.sh
AZURE_IMAGE_VERSION=2.2.0 AZURE_RESOURCE_GROUP_NAME=constellation-images AZURE_IMAGE_FILE=./constellation.img ./importAzure.sh
-

The script creates the following resources:

-
    -
  1. A new image gallery with the default name constellation-import
    2. -
  2. A new image definition with the default name constellation
    3. -
  3. The actual image with the provided version. In this case 2.2.0
    4. -
-

Once the import is completed, use the ID of the image version in your constellation-conf.yaml for the image field. Set confidentialVM to false.

-

Fetch the image measurements:

Version: 2.23

Upgrade your cluster

-

Constellation provides an easy way to upgrade all components of your cluster, without disrupting its availability. -Specifically, you can upgrade the Kubernetes version, the nodes' image, and the Constellation microservices. -You configure the desired versions in your local Constellation configuration and trigger upgrades with the apply command. -To learn about available versions you use the upgrade check command. -Which versions are available depends on the CLI version you are using.

-

Update the CLI​

-

Each CLI comes with a set of supported microservice and Kubernetes versions. -Most importantly, a given CLI version can only upgrade a cluster of the previous minor version, but not older ones. -This means that you have to upgrade your CLI and cluster one minor version at a time.

-

For example, if you are currently on CLI version v2.6 and the latest version is v2.8, you should

-
    -
  • upgrade the CLI to v2.7,
    • -
  • upgrade the cluster to v2.7,
    • -
  • and only then continue upgrading the CLI (and the cluster) to v2.8 after.
    • -
-

Also note that if your current Kubernetes version isn't supported by the next CLI version, use your current CLI to upgrade to a newer Kubernetes version first.

-

To learn which Kubernetes versions are supported by a particular CLI, run constellation config kubernetes-versions.

-

Migrate the configuration​

-

The Constellation configuration file is located in the file constellation-conf.yaml in your workspace. -Refer to the migration reference to check if you need to update fields in your configuration file. -Use constellation config migrate to automatically update an old config file to a new format.

-

Check for upgrades​

-

To learn which versions the current CLI can upgrade to and what's installed in your cluster, run:

-
# Show possible upgrades
constellation upgrade check

# Show possible upgrades and write them to config file
constellation upgrade check --update-config
-

You can either enter the reported target versions into your config manually or run the above command with the --update-config flag. -When using this flag, the kubernetesVersion, image, microserviceVersion, and attestation fields are overwritten with the smallest available upgrade.

-

Apply the upgrade​

-

Once you updated your config with the desired versions, you can trigger the upgrade with this command:

-
constellation apply
-

Microservice upgrades will be finished within a few minutes, depending on the cluster size. -If you are interested, you can monitor pods restarting in the kube-system namespace with your tool of choice.

-

Image and Kubernetes upgrades take longer. -For each node in your cluster, a new node has to be created and joined. -The process usually takes up to ten minutes per node.

-

When applying an upgrade, the Helm charts for the upgrade as well as backup files of Constellation-managed Custom Resource Definitions, Custom Resources, and Terraform state are created. -You can use the Terraform state backup to restore previous resources in case an upgrade misconfigured or erroneously deleted a resource. -You can use the Custom Resource (Definition) backup files to restore Custom Resources and Definitions manually (e.g., via kubectl apply) if the automatic migration of those resources fails. -You can use the Helm charts to manually apply upgrades to the Kubernetes resources, should an upgrade fail.

-
note

For advanced users: the upgrade consists of several phases that can be individually skipped through the --skip-phases flag. -The phases are infrastracture for the cloud resource management through Terraform, helm for the chart management of the microservices, image for OS image upgrades, and k8s for Kubernetes version upgrades.

-

Check the status​

-

Upgrades are asynchronous operations. -After you run apply, it will take a while until the upgrade has completed. -To understand if an upgrade is finished, you can run:

-
constellation status
-

This command displays the following information:

-
    -
  • The installed services and their versions
    • -
  • The image and Kubernetes version the cluster is expecting on each node
    • -
  • How many nodes are up to date
    • -
-

Here's an example output:

-
Target versions:
    Image: v2.6.0
    Kubernetes: v1.25.8
Service versions:
    Cilium: v1.12.1
    cert-manager: v1.10.0
    constellation-operators: v2.6.0
    constellation-services: v2.6.0
Cluster status: Some node versions are out of date
    Image: 23/25
    Kubernetes: 25/25
-

This output indicates that the cluster is running Kubernetes version 1.25.8, and all nodes have the appropriate binaries installed. -23 out of 25 nodes have already upgraded to the targeted image version of 2.6.0, while two are still in progress.

-

Apply further upgrades​

-

After the upgrade is finished, you can run constellation upgrade check again to see if there are more upgrades available. If so, repeat the process.

Edgeless Systems uses sigstore and SLSA to ensure supply-chain security for the Constellation CLI and node images ("artifacts"). sigstore consists of three components: Cosign, Rekor, and Fulcio. Edgeless Systems uses Cosign to sign artifacts. All signatures are uploaded to the public Rekor transparency log, which resides at https://rekor.sigstore.dev.

-
note

The public key for Edgeless Systems' long-term code-signing key is:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEf8F1hpmwE+YCFXzjGtaQcrL6XZVT
JmEe5iSLvG1SyQSAew7WdMKF6o9t8e2TFuCkzlOhhlws2OHWbiFZnFWCFw==
-----END PUBLIC KEY-----

The public key is also available for download at https://edgeless.systems/es.pub and in the Twitter profile @EdgelessSystems.

-

The Rekor transparency log is a public append-only ledger that verifies and records signatures and associated metadata. The Rekor transparency log enables everyone to observe the sequence of (software) signatures issued by Edgeless Systems and many other parties. The transparency log allows for the public identification of dubious or malicious signatures.

-

You should always ensure that (1) your CLI executable was signed with the private key corresponding to the above public key and that (2) there is a corresponding entry in the Rekor transparency log. Both can be done as described in the following.

-
info

You don't need to verify the Constellation node images. This is done automatically by your CLI and the rest of Constellation.

-

Verify the signature​

-
info

This guide assumes Linux on an amd64 processor. The exact steps for other platforms differ slightly.

-

First, install the Cosign CLI. Next, download and verify the signature that accompanies your CLI executable, for example:

-
$ cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

Verified OK
-

The above performs an offline verification of the provided public key, signature, and executable. To also verify that a corresponding entry exists in the public Rekor transparency log, add the variable COSIGN_EXPERIMENTAL=1:

-
$ COSIGN_EXPERIMENTAL=1 cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

tlog entry verified with uuid: afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13 index: 3477047
Verified OK
-

🏁 You now know that your CLI executable was officially released and signed by Edgeless Systems.

-

Optional: Manually inspect the transparency log​

-

To further inspect the public Rekor transparency log, install the Rekor CLI. A search for the CLI executable should give a single UUID. (Note that this UUID contains the UUID from the previous cosign command.)

-
$ rekor-cli search --artifact constellation-linux-amd64

Found matching entries (listed by UUID):
362f8ecba72f4326afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13
-

With this UUID you can get the full entry from the transparency log:

-

You can get an exhaustive list of artifact signatures issued by Edgeless Systems via the following command:

-
rekor-cli search --public-key https://edgeless.systems/es.pub --pki-format x509
-

Edgeless Systems monitors this list to detect potential unauthorized use of its private key.

-

Verify the provenance​

-

Provenance attests that a software artifact was produced by a specific repository and build system invocation. For more information on provenance visit slsa.dev and learn about the adoption of SLSA for Constellation.

-

Just as checking its signature proves that the CLI hasn't been manipulated, checking the provenance proves that the artifact was produced by the expected build process and hasn't been tampered with.

-

To verify the provenance, first install the slsa-verifier. Then make sure you have the provenance file (constellation.intoto.jsonl) and Constellation CLI downloaded. Both are available on the GitHub release page.

-
info

The same provenance file is valid for all Constellation CLI executables of a given version independent of the target platform.

-

Use the verifier to perform the check:

-
$ slsa-verifier verify-artifact constellation-linux-amd64 \
  --provenance-path constellation.intoto.jsonl \
  --source-uri github.com/edgelesssys/constellation

Verify your cluster

-

Constellation's attestation feature allows you, or a third party, to verify the integrity and confidentiality of your Constellation cluster.

-

Fetch measurements​

-

To verify the integrity of Constellation you need trusted measurements to verify against. For each node image released by Edgeless Systems, there are signed measurements, which you can download using the CLI:

-
constellation config fetch-measurements
-

This command performs the following steps:

-
    -
  1. Download the signed measurements for the configured image. By default, this will use Edgeless Systems' public measurement registry.
    2. -
  2. Verify the signature of the measurements. This will use Edgeless Systems' public key.
    3. -
  3. Write measurements into configuration file.
    4. -
-

The configuration file then contains a list of measurements similar to the following:

-
# ...
measurements:
    0:
        expected: "0f35c214608d93c7a6e68ae7359b4a8be5a0e99eea9107ece427c4dea4e439cf"

-

Each entry specifies the expected value of the Constellation node, and whether the measurement should be enforced (warnOnly: false), or only a warning should be logged (warnOnly: true). -By default, the subset of the available measurements that can be locally reproduced and verified is enforced.

-

During attestation, the validating side (CLI or join service) compares each measurement reported by the issuing side (first node or joining node) individually. -For mismatching measurements that have set warnOnly to true only a warning is emitted. -For mismatching measurements that have set warnOnly to false an error is emitted and attestation fails. -If attestation fails for a new node, it isn't permitted to join the cluster.

-

The verify command​

-
note

The steps below are purely optional. They're automatically executed by constellation apply when you initialize your cluster. The constellation verify command mostly has an illustrative purpose.

-

The verify command obtains and verifies an attestation statement from a running Constellation cluster.

-
constellation verify [--cluster-id ...]
-

From the attestation statement, the command verifies the following properties:

-
    -
  • The cluster is using the correct Confidential VM (CVM) type.
    • -
  • Inside the CVMs, the correct node images are running. The node images are identified through the measurements obtained in the previous step.
    • -
  • The unique ID of the cluster matches the one from your constellation-state.yaml file or passed in via --cluster-id.
    • -
-

Once the above properties are verified, you know that you are talking to the right Constellation cluster and it's in a good and trustworthy shape.

-

Custom arguments​

-

The verify command also allows you to verify any Constellation deployment that you have network access to. For this you need the following:

-
    -
  • The IP address of a running Constellation cluster's VerificationService. The VerificationService is exposed via a NodePort service using the external IP address of your cluster. Run kubectl get nodes -o wide and look for EXTERNAL-IP.
    • -
  • The cluster's clusterID. See cluster identity for more details.
    • -
  • A constellation-conf.yaml file with the expected measurements of the cluster in your working directory.
    • -
-

For example:

-
constellation verify -e 192.0.2.1 --cluster-id Q29uc3RlbGxhdGlvbkRvY3VtZW50YXRpb25TZWNyZXQ=

Attestation

-

This page explains Constellation's attestation process and highlights the cornerstones of its trust model.

-

Terms​

-

The following lists terms and concepts that help to understand the attestation concept of Constellation.

-

Trusted Platform Module (TPM)​

-

A TPM chip is a dedicated tamper-resistant crypto-processor. -It can securely store artifacts such as passwords, certificates, encryption keys, or runtime measurements (more on this below). -When a TPM is implemented in software, it's typically called a virtual TPM (vTPM).

-

Runtime measurement​

-

A runtime measurement is a cryptographic hash of the memory pages of a so called runtime component. Runtime components of interest typically include a system's bootloader or OS kernel.

-

Platform Configuration Register (PCR)​

-

A Platform Configuration Register (PCR) is a memory location in the TPM that has some unique properties. -To store a new value in a PCR, the existing value is extended with a new value as follows:

-
PCR[N] = HASHalg( PCR[N] || ArgumentOfExtend )
-

The PCRs are typically used to store runtime measurements. -The new value of a PCR is always an extension of the existing value. -Thus, storing the measurements of multiple components into the same PCR irreversibly links them together.

-

Measured boot​

-

Measured boot builds on the concept of chained runtime measurements. -Each component in the boot chain loads and measures the next component into the PCR before executing it. -By comparing the resulting PCR values against trusted reference values, the integrity of the entire boot chain and thereby the running system can be ensured.

-

Remote attestation (RA)​

-

Remote attestation is the process of verifying certain properties of an application or platform, such as integrity and confidentiality, from a remote location. -In the case of a measured boot, the goal is to obtain a signed attestation statement on the PCR values of the boot measurements. -The statement can then be verified and compared to a set of trusted reference values. -This way, the integrity of the platform can be ensured before sharing secrets with it.

-

Confidential virtual machine (CVM)​

-

Confidential computing (CC) is the protection of data in-use with hardware-based trusted execution environments (TEEs). -With CVMs, TEEs encapsulate entire virtual machines and isolate them against the hypervisor, other VMs, and direct memory access. -After loading the initial VM image into encrypted memory, the hypervisor calls for a secure processor to measure these initial memory pages. -The secure processor locks these pages and generates an attestation report on the initial page measurements. -CVM memory pages are encrypted with a key that resides inside the secure processor, which makes sure only the guest VM can access them. -The attestation report is signed by the secure processor and can be verified using remote attestation via the certificate authority of the hardware vendor. -Such an attestation statement guarantees the confidentiality and integrity of a CVM.

-

Attested TLS (aTLS)​

-

In a CC environment, attested TLS (aTLS) can be used to establish secure connections between two parties using the remote attestation features of the CC components.

-

aTLS modifies the TLS handshake by embedding an attestation statement into the TLS certificate. -Instead of relying on a certificate authority, aTLS uses this attestation statement to establish trust in the certificate.

-

The protocol can be used by clients to verify a server certificate, by a server to verify a client certificate, or for mutual verification (mutual aTLS).

-

Overview​

-

The challenge for Constellation is to lift a CVM's attestation statement to the Kubernetes software layer and make it end-to-end verifiable. -From there, Constellation needs to expand the attestation from a single CVM to the entire cluster.

-

The JoinService and VerificationService are where all runs together. -Internally, the JoinService uses remote attestation to securely join CVM nodes to the cluster. -Externally, the VerificationService provides an attestation statement for the cluster's CVMs and configuration.

-

The following explains the details of both steps.

-

Node attestation​

-

The idea is that Constellation nodes should have verifiable integrity from the CVM hardware measurement up to the Kubernetes software layer. -The solution is a verifiable boot chain and an integrity-protected runtime environment.

-

Constellation uses measured boot within CVMs, measuring each component in the boot process before executing it. -Outside of CC, this is usually implemented via TPMs. -CVM technologies differ in how they implement runtime measurements, but the general concepts are similar to those of a TPM. -For simplicity, TPM terminology like PCR is used in the following.

-

When a Constellation node image boots inside a CVM, measured boot is used for all stages and components of the boot chain. -This process goes up to the root filesystem. -The root filesystem is mounted read-only with integrity protection. -For the details on the image and boot stages see the image architecture documentation. -Any changes to the image will inevitably also change the corresponding PCR values. -To create a node attestation statement, the Constellation image obtains a CVM attestation statement from the hardware. -This includes the runtime measurements and thereby binds the measured boot results to the CVM hardware measurement.

-

In addition to the image measurements, Constellation extends a PCR during the initialization phase that irrevocably marks the node as initialized. -The measurement is created using the clusterID, tying all future attestation statements to this ID. -Thereby, an attestation statement is unique for every cluster and a node can be identified unambiguously as being initialized.

-

To verify an attestation, the hardware's signature and a statement are verified first to establish trust in the contained runtime measurements. -If successful, the measurements are verified against the trusted values of the particular Constellation release version. -Finally, the measurement of the clusterID can be compared by calculating it with the master secret.

-

Runtime measurements​

-

Constellation uses runtime measurements to implement the measured boot approach. -As stated above, the underlying hardware technology and guest firmware differ in their implementations of runtime measurements. -The following gives a detailed description of the available measurements in the different cloud environments.

-

The runtime measurements consist of two types of values:

-
    -
  • -

    Measurements produced by the cloud infrastructure and firmware of the CVM: -These are measurements of closed-source firmware and other values controlled by the cloud provider. -While not being reproducible for the user, some of them can be compared against previously observed values. -Others may change frequently and aren't suitable for verification. -The signed image measurements include measurements that are known, previously observed values.

    -
    • -
  • -

    Measurements produced by the Constellation bootloader and boot chain: -The Constellation Bootloader takes over from the CVM firmware and measures the rest of the boot chain. -The Constellation Bootstrapper is the first user mode component that runs in a Constellation image. -It extends PCR registers with the IDs of the cluster marking a node as initialized.

    -
    • -
-

Constellation allows to specify in the config which measurements should be enforced during the attestation process. -Enforcing non-reproducible measurements controlled by the cloud provider means that changes in these values require manual updates to the cluster's config. -By default, Constellation only enforces measurements that are stable values produced by the infrastructure or by Constellation directly.

-

Constellation uses the vTPM (NitroTPM) feature of the AWS Nitro System on AWS for runtime measurements.

The vTPM adheres to the TPM 2.0 specification. -The VMs are attested by obtaining signed PCR values over the VM's boot configuration from the TPM and comparing them to a known, good state (measured boot).

The following table lists all PCR values of the vTPM and the measured components. -It also lists what components of the boot chain did the measurements and if the value is reproducible and verifiable. -The latter means that the value can be generated offline and compared to the one in the vTPM.

CVM verification​

-

To verify the integrity of the received attestation statement, a chain of trust from the CVM technology to the interface providing the statement has to be established. -For verification of the CVM technology, Constellation may expose additional options in its config file.

-

On AWS, AMD SEV-SNP is used to provide runtime encryption to the VMs. -An SEV-SNP attestation report is used to establish trust in the VM. -You may customize certain parameters for verification of the attestation statement using the Constellation config file.

    -
  • -

    TCB versions

    -

    You can set the minimum version numbers of components in the SEV-SNP TCB. -Use the latest versions to enforce that only machines with the most recent firmware updates are allowed to join the cluster. -Alternatively, you can set a lower minimum version to allow slightly out-of-date machines to still be able to join the cluster.

    -
    • -
  • -

    AMD Root Key Certificate

    -

    This certificate is the root of trust for verifying the SEV-SNP certificate chain.

    -
    • -
  • -

    AMD Signing Key Certificate

    -

    This is the intermediate certificate for verifying the SEV-SNP report's signature. -If it's not specified, the CLI fetches it from the AMD key distribution server.

    -
    • -
-

Cluster attestation​

-

Cluster-facing, Constellation's JoinService verifies each node joining the cluster given the configured ground truth runtime measurements. -User-facing, the VerificationService provides an interface to verify a node using remote attestation. -By verifying the first node during the initialization and configuring the ground truth measurements that are subsequently enforced by the JoinService, the whole cluster is verified in a transitive way.

-

Cluster-facing attestation​

-

The JoinService is provided with the runtime measurements of the whitelisted Constellation image version as the ground truth. -During the initialization and the cluster bootstrapping, each node connects to the JoinService using aTLS. -During the handshake, the node transmits an attestation statement including its runtime measurements. -The JoinService verifies that statement and compares the measurements against the ground truth. -For details of the initialization process check the microservice descriptions.

-

After the initialization, every node updates its runtime measurements with the clusterID value, marking it irreversibly as initialized. -When an initialized node tries to join another cluster, its measurements inevitably mismatch the measurements of an uninitialized node and it will be declined.

-

User-facing attestation​

-

The VerificationService provides an endpoint for obtaining its hardware-based remote attestation statement, which includes the runtime measurements. -A user can verify this statement and compare the measurements against the configured ground truth and, thus, verify the identity and integrity of all Constellation components and the cluster configuration. Subsequently, the user knows that the entire cluster is in the expected state and is trustworthy.

-

Putting it all together​

-

This section puts the aforementioned concepts together and illustrate how trust into a Constellation cluster is established and maintained.

-

CLI and node images​

-

It all starts with the CLI executable. The CLI is signed by Edgeless Systems. To ensure non-repudiability for CLI releases, Edgeless Systems publishes corresponding signatures to the public ledger of the sigstore project. There's a step-by-step guide on how to verify CLI signatures based on sigstore.

-

The CLI contains the latest runtime measurements of the Constellation node image for all supported cloud platforms. In case a different version of the node image is to be used, the corresponding runtime measurements can be fetched using the CLI's fetch-measurements command. This command downloads the runtime measurements and the corresponding signature from cdn.confidential.cloud. See for example the following files corresponding to node image v2.16.3:

- -

The CLI contains the long-term public key of Edgeless Systems to verify the signature of downloaded runtime measurements.

-

Cluster creation​

-

When a cluster is created, the CLI automatically verifies the runtime measurements of the first node using remote attestation. Based on this, the CLI and the first node set up a temporary TLS connection. This aTLS connection is used for two things:

-
    -
  1. The CLI sends the master secret of the to-be-created cluster to the CLI. The master secret is generated by the first node.
    2. -
  2. The first node sends a kubeconfig file with Kubernetes credentials to the CLI.
    3. -
-

After this, the aTLS connection is closed and the first node bootstraps the Kubernetes cluster. All subsequent interactions between the CLI and the cluster go via the Kubernetes API server running inside the cluster. The CLI (and other tools like kubectl) use the credentials referenced by the kubeconfig file to authenticate themselves towards the Kubernetes API server and to establish a mTLS connection.

-

The CLI connects to the Kubernetes API to write the runtime measurements for the applicable node image to etcd. The JoinService uses these runtime measurements to verify all nodes that join the cluster subsequently.

-

Chain of trust​

-

In summary, there's a chain of trust based on cryptographic signatures that goes from the user to the cluster via the CLI. This is illustrated in the following diagram.

- -

Upgrades​

-

Whenever a cluster is upgraded to a new version of the node image, the CLI sends the corresponding runtime measurements via the Kubernetes API server. The new runtime measurements are stored in etcd within the cluster and replace any previous runtime measurements. The new runtime measurements are then used automatically by the JoinService for the verification of new nodes.

Encrypted persistent storage

-

Confidential VMs provide runtime memory encryption to protect data in use. -In the context of Kubernetes, this is sufficient for the confidentiality and integrity of stateless services. -Consider a front-end web server, for example, that keeps all connection information cached in main memory. -No sensitive data is ever written to an insecure medium. -However, many real-world applications need some form of state or data-lake service that's connected to a persistent storage device and requires encryption at rest. -As described in Use persistent storage, cloud service providers (CSPs) use the container storage interface (CSI) to make their storage solutions available to Kubernetes workloads. -These CSI storage solutions often support some sort of encryption. -For example, Google Cloud encrypts data at rest by default, without any action required by the customer.

-

Cloud provider-managed encryption​

-

CSP-managed storage solutions encrypt the data in the cloud backend before writing it physically to disk. -In the context of confidential computing and Constellation, the CSP and its managed services aren't trusted. -Hence, cloud provider-managed encryption protects your data from offline hardware access to physical storage devices. -It doesn't protect it from anyone with infrastructure-level access to the storage backend or a malicious insider in the cloud platform. -Even with "bring your own key" or similar concepts, the CSP performs the encryption process with access to the keys and plaintext data.

-

In the security model of Constellation, securing persistent storage and thereby data at rest requires that all cryptographic operations are performed inside a trusted execution environment. -Consequently, using CSP-managed encryption of persistent storage usually isn't an option.

-

Constellation-managed encryption​

-

Constellation provides CSI drivers for storage solutions in all major clouds with built-in encryption support. -Block storage provisioned by the CSP is mapped using the dm-crypt, and optionally the dm-integrity, kernel modules, before it's formatted and accessed by the Kubernetes workloads. -All cryptographic operations happen inside the trusted environment of the confidential Constellation node.

-

Note that for integrity-protected disks, volume expansion isn't supported.

-

By default the driver uses data encryption keys (DEKs) issued by the Constellation KeyService. -The DEKs are in turn derived from the Constellation's key encryption key (KEK), which is directly derived from the master secret. -This is the recommended mode of operation, and also requires the least amount of setup by the cluster administrator.

-

Alternatively, the driver can be configured to use a key management system to store and access KEKs and DEKs.

-

Refer to keys and cryptography for more details on key management in Constellation.

-

Once deployed and configured, the CSI driver ensures transparent encryption and integrity of all persistent volumes provisioned via its storage class. -Data at rest is secured without any additional actions required by the developer.

-

Cryptographic algorithms​

-

This section gives an overview of the libraries, cryptographic algorithms, and their configurations, used in Constellation's CSI drivers.

-

dm-crypt​

-

To interact with the dm-crypt kernel module, Constellation uses libcryptsetup. -New devices are formatted as LUKS2 partitions with a sector size of 4096 bytes. -The used key derivation function is Argon2id with the recommended parameters for memory-constrained environments of 3 iterations and 64 MiB of memory, utilizing 4 parallel threads. -For encryption Constellation uses AES in XTS-Plain64. The key size is 512 bit.

-

dm-integrity​

-

To interact with the dm-integrity kernel module, Constellation uses libcryptsetup. -When enabled, the used data integrity algorithm is HMAC with SHA256 as the hash function. -The tag size is 32 Bytes.

-

Encrypted S3 object storage​

-

Constellation comes with a service that you can use to transparently retrofit client-side encryption to existing applications that use S3 (AWS or compatible) for storage. -To learn more, check out the s3proxy documentation.

Constellation images

-

Constellation uses a minimal version of Fedora as the operating system running inside confidential VMs. This Linux distribution is optimized for containers and designed to be stateless. -The Constellation images provide measured boot and an immutable filesystem.

-

Measured boot​

- -

Measured boot uses a Trusted Platform Module (TPM) to measure every part of the boot process. This allows for verification of the integrity of a running system at any point in time. To ensure correct measurements of every stage, each stage is responsible to measure the next stage before transitioning.

-

Firmware​

-

With confidential VMs, the firmware is the root of trust and is measured automatically at boot. After initialization, the firmware will load and measure the bootloader before executing it.

-

Bootloader​

-

The bootloader is the first modifiable part of the boot chain. The bootloader is tasked with loading the kernel, initramfs and setting the kernel command line. The Constellation bootloader measures these components before starting the kernel.

-

initramfs​

-

The initramfs is a small filesystem loaded to prepare the actual root filesystem. The Constellation initramfs maps the block device containing the root filesystem with dm-verity. The initramfs then mounts the root filesystem from the mapped block device.

-

dm-verity provides integrity checking using a cryptographic hash tree. When a block is read, its integrity is checked by verifying the tree against a trusted root hash. The initramfs reads this root hash from the previously measured kernel command line. Thus, if any block of the root filesystem's device is modified on disk, trying to read the modified block will result in a kernel panic at runtime.

-

After mounting the root filesystem, the initramfs will switch over and start the init process of the integrity-protected root filesystem.

-

State disk​

-

In addition to the read-only root filesystem, each Constellation node has a disk for storing state data. -This disk is mounted readable and writable by the initramfs and contains data that should persist across reboots. -Such data can contain sensitive information and, therefore, must be stored securely. -To that end, the state disk is protected by authenticated encryption. -See the section on keys and encryption for more information on the cryptographic primitives in use.

-

Kubernetes components​

-

During initialization, the Bootstrapper downloads and verifies the Kubernetes components as configured by the user. -They're stored on the state partition and can be updated once new releases need to be installed.

Key management and cryptographic primitives

-

Constellation protects and isolates your cluster and workloads. -To that end, cryptography is the foundation that ensures the confidentiality and integrity of all components. -Evaluating the security and compliance of Constellation requires a precise understanding of the cryptographic primitives and keys used. -The following gives an overview of the architecture and explains the technical details.

-

Confidential VMs​

-

Confidential VM (CVM) technology comes with hardware and software components for memory encryption, isolation, and remote attestation. -For details on the implementations and cryptographic soundness, refer to the hardware vendors' documentation and advisories.

-

Master secret​

-

The master secret is the cryptographic material used for deriving the clusterID and the key encryption key (KEK) for storage encryption. -It's generated during the bootstrapping of a Constellation cluster. -It can either be managed by Constellation or an external key management system. -In case of recovery, the master secret allows to decrypt the state and recover a Constellation cluster.

-

Cluster identity​

-

The identity of a Constellation cluster is represented by cryptographic measurements:

-

The base measurements represent the identity of a valid, uninitialized Constellation node. -They depend on the node image, but are otherwise the same for every Constellation cluster. -On node boot, they're determined using the CVM's attestation mechanism and measured boot up to the read-only root filesystem.

-

The clusterID represents the identity of a single initialized Constellation cluster. -It's derived from the master secret and a cryptographically random salt and unique for every Constellation cluster. -The Bootstrapper measures the clusterID into its own PCR before executing any code not measured as part of the base measurements. -See Node attestation for details.

-

The remote attestation statement of a Constellation cluster combines the base measurements and the clusterID for a verifiable, unspoofable, unique identity.

-

Network encryption​

-

Constellation encrypts all cluster network communication using the container network interface (CNI). -See network encryption for more details.

-

The Cilium agent running on each node establishes a secure WireGuard tunnel between it and all other known nodes in the cluster. -Each node creates its own Curve25519 encryption key pair and distributes its public key via Kubernetes. -A node uses another node's public key to decrypt and encrypt traffic from and to Cilium-managed endpoints running on that node. -Connections are always encrypted peer-to-peer using ChaCha20 with Poly1305. -WireGuard implements forward secrecy with key rotation every 2 minutes.

-

Storage encryption​

-

Constellation supports transparent encryption of persistent storage. -The Linux kernel's device mapper-based encryption features are used to encrypt the data on the block storage level. -Currently, the following primitives are used for block storage encryption:

- -

Adding primitives for integrity protection in the CVM attacker model are under active development and will be available in a future version of Constellation. -See encrypted storage for more details.

-

As a cluster administrator, when creating a cluster, you can use the Constellation installation program to select one of the following methods for key management:

-
    -
  • Constellation-managed key management
    • -
  • User-managed key management
    • -
-

Constellation-managed key management​

-

Key material and key derivation​

-

During the creation of a Constellation cluster, the cluster's master secret is used to derive a KEK. -This means creating two clusters with the same master secret will yield the same KEK. -Any data encryption key (DEK) is derived from the KEK via HKDF. -Note that the master secret is recommended to be unique for every cluster and shouldn't be reused (except in case of recovering a cluster).

-

State and storage​

-

The KEK is derived from the master secret during the initialization. -Subsequently, all other key material is derived from the KEK. -Given the same KEK, any DEK can be derived deterministically from a given identifier. -Hence, there is no need to store DEKs. They can be derived on demand. -After the KEK was derived, it's stored in memory only and never leaves the CVM context.

-

Availability​

-

Constellation-managed key management has the same availability as the underlying Kubernetes cluster. -Therefore, the KEK is stored in the distributed Kubernetes etcd storage to allow for unexpected but non-fatal (control-plane) node failure. -The etcd storage is backed by the encrypted and integrity protected state disk of the nodes.

-

Recovery​

-

Constellation clusters can be recovered in the event of a disaster, even when all node machines have been stopped and need to be rebooted. -For details on the process see the recovery workflow.

-

User-managed key management​

-

User-managed key management is under active development and will be available soon. -In scenarios where constellation-managed key management isn't an option, this mode allows you to keep full control of your keys. -For example, compliance requirements may force you to keep your KEKs in an on-prem key management system (KMS).

-

During the creation of a Constellation cluster, you specify a KEK present in a remote KMS. -This follows the common scheme of "bring your own key" (BYOK). -Constellation will support several KMSs for managing the storage and access of your KEK. -Initially, it will support the following KMSs:

- -

Storing the keys in Cloud KMS of AWS, Azure, or GCP binds the key usage to the particular cloud identity access management (IAM). -In the future, Constellation will support remote attestation-based access policies for Cloud KMS once available. -Note that using a Cloud KMS limits the isolation and protection to the guarantees of the particular offering.

-

KMIP support allows you to use your KMIP-compatible on-prem KMS and keep full control over your keys. -This follows the common scheme of "hold your own key" (HYOK).

-

The KEK is used to encrypt per-data "data encryption keys" (DEKs). -DEKs are generated to encrypt your data before storing it on persistent storage. -After being encrypted by the KEK, the DEKs are stored on dedicated cloud storage for persistence. -Currently, Constellation supports the following cloud storage options:

- -

The DEKs are only present in plaintext form in the encrypted main memory of the CVMs. -Similarly, the cryptographic operations for encrypting data before writing it to persistent storage are performed in the context of the CVMs.

-

Recovery and migration​

-

In the case of a disaster, the KEK can be used to decrypt the DEKs locally and subsequently use them to decrypt and retrieve the data. -In case of migration, configuring the same KEK will provide seamless migration of data. -Thus, only the DEK storage needs to be transferred to the new cluster alongside the encrypted data for seamless migration.

Microservices

-

Constellation takes care of bootstrapping and initializing a Confidential Kubernetes cluster. -During the lifetime of the cluster, it handles day 2 operations such as key management, remote attestation, and updates. -These features are provided by several microservices:

- -

The relations between microservices are shown in the following diagram:

- -

Bootstrapper​

-

The Bootstrapper is the first microservice launched after booting a Constellation node image. -It sets up that machine as a Kubernetes node and integrates that node into the Kubernetes cluster. -To this end, the Bootstrapper first downloads and verifies the Kubernetes components at the configured versions. -The Bootstrapper tries to find an existing cluster and if successful, communicates with the JoinService to join the node. -Otherwise, it waits for an initialization request to create a new Kubernetes cluster.

-

JoinService​

-

The JoinService runs as DaemonSet on each control-plane node. -New nodes (at cluster start, or later through autoscaling) send a request to the service over attested TLS (aTLS). -The JoinService verifies the new node's certificate and attestation statement. -If attestation is successful, the new node is supplied with an encryption key from the KeyService for its state disk, and a Kubernetes bootstrap token.

- -

VerificationService​

-

The VerificationService runs as DaemonSet on each node. -It provides user-facing functionality for remote attestation during the cluster's lifetime via an endpoint for verifying the cluster. -Read more about the hardware-based attestation feature of Constellation and how to verify a cluster on the client side.

-

KeyService​

-

The KeyService runs as DaemonSet on each control-plane node. -It implements the key management for the storage encryption keys in Constellation. These keys are used for the state disk of each node and the transparently encrypted storage for Kubernetes. -Depending on wether the constellation-managed or user-managed mode is used, the KeyService holds the key encryption key (KEK) directly or calls an external key management service (KMS) for key derivation respectively.

Network encryption

-

Constellation encrypts all pod communication using the container network interface (CNI). -To that end, Constellation deploys, configures, and operates the Cilium CNI plugin. -Cilium provides transparent encryption for all cluster traffic using either IPSec or WireGuard. -Currently, Constellation only supports WireGuard as the encryption engine. -You can read more about the cryptographic soundness of WireGuard in their white paper.

-

Cilium is actively working on implementing a feature called host-to-host encryption mode for WireGuard. -With host-to-host, all traffic between nodes will be tunneled via WireGuard (host-to-host, host-to-pod, pod-to-host, pod-to-pod). -Until the host-to-host feature is released, Constellation enables pod-to-pod encryption. -This mode encrypts all traffic between Kubernetes pods using WireGuard tunnels.

-

When using Cilium in the default setup but with encryption enabled, there is a known issue -that can cause pod-to-pod traffic to be unencrypted. -To mitigate this issue, Constellation adds a strict mode to Cilium's pod-to-pod encryption. -This mode changes the default behavior of traffic that's destined for an unknown endpoint to not be send out in plaintext, but instead being dropped. -The strict mode distinguishes between traffic that's send to a pod from traffic that's destined for a cluster-external endpoint by considering the pod's CIDR range.

-

Traffic originating from hosts isn't encrypted yet. -This mainly includes health checks from Kubernetes API server. -Also, traffic proxied over the API server via e.g. kubectl port-forward isn't encrypted.

Observability

-

In Kubernetes, observability is the ability to gain insight into the behavior and performance of applications. -It helps identify and resolve issues more effectively, ensuring stability and performance of Kubernetes workloads, reducing downtime and outages, and improving efficiency. -The "three pillars of observability" are logs, metrics, and traces.

-

In the context of Confidential Computing, observability is a delicate subject and needs to be applied such that it doesn't leak any sensitive information. -The following gives an overview of where and how you can apply standard observability tools in Constellation.

-

Cloud resource monitoring​

-

While inaccessible, Constellation's nodes are still visible as black box VMs to the hypervisor. -Resource consumption, such as memory and CPU utilization, can be monitored from the outside and observed via the cloud platforms directly. -Similarly, other resources, such as storage and network and their respective metrics, are visible via the cloud platform.

-

Metrics​

-

Metrics are numeric representations of data measured over intervals of time. They're essential for understanding system health and gaining insights using telemetry signals.

-

By default, Constellation exposes the metrics for Kubernetes system components inside the cluster. -Similarly, the etcd metrics endpoints are exposed inside the cluster. -These metrics endpoints can be disabled.

-

You can collect these cluster-internal metrics via tools such as Prometheus or the Elastic Stack.

-

Constellation's CNI Cilium also supports metrics via Prometheus endpoints. -However, in Constellation, they're disabled by default and must be enabled first.

-

Logs​

-

Logs represent discrete events that usually describe what's happening with your service. -The payload is an actual message emitted from your system along with a metadata section containing a timestamp, labels, and tracking identifiers.

-

System logs​

-

Detailed system-level logs are accessible via /var/log and journald on the nodes directly. -They can be collected from there, for example, via Filebeat and Logstash, which are tools of the Elastic Stack.

-

In case of an error during the initialization, the CLI automatically collects the Bootstrapper logs and returns these as a file for troubleshooting. Here is an example of such an event:

-
Cluster initialization failed. This error is not recoverable.
Terminate your cluster and try again.
Fetched bootstrapper logs are stored in "constellation-cluster.log"
-

Kubernetes logs​

-

Constellation supports the Kubernetes logging architecture. -By default, logs are written to the nodes' encrypted state disks. -These include the Pod and container logs and the system component logs.

-

Constellation services run as Pods inside the kube-system namespace and use the standard container logging mechanism. -The same applies for the Cilium Pods.

-

You can collect logs from within the cluster via tools such as Fluentd, Loki, or the Elastic Stack.

-

Traces​

-

Modern systems are implemented as interconnected complex and distributed microservices. Understanding request flows and system communications is challenging, mainly because all systems in a chain need to be modified to propagate tracing information. Distributed tracing is a new approach to increasing observability and understanding performance bottlenecks. A trace represents consecutive events that reflect an end-to-end request path in a distributed system.

-

Constellation supports traces for Kubernetes system components. -By default, they're disabled and need to be enabled first.

-

Similarly, Cilium can be enabled to export traces.

-

You can collect these traces via tools such as Jaeger or Zipkin.

-

Integrations​

-

Platforms and SaaS solutions such as Datadog, logz.io, Dynatrace, or New Relic facilitate the observability challenge for Kubernetes and provide all-in-one SaaS solutions. -They install agents into the cluster that collect metrics, logs, and tracing information and upload them into the data lake of the platform. -Technically, the agent-based approach is compatible with Constellation, and attaching these platforms is straightforward. -However, you need to evaluate if the exported data might violate Constellation's compliance and privacy guarantees by uploading them to a third-party platform.

Orchestrating Constellation clusters

-

You can use the CLI to create a cluster on the supported cloud platforms. -The CLI provisions the resources in your cloud environment and initiates the initialization of your cluster. -It uses a set of parameters and an optional configuration file to manage your cluster installation. -The CLI is also used for updating your cluster.

-

Workspaces​

-

Each Constellation cluster has an associated workspace. -The workspace is where data such as the Constellation state and config files are stored. -Each workspace is associated with a single cluster and configuration. -The CLI stores state in the local filesystem making the current directory the active workspace. -Multiple clusters require multiple workspaces, hence, multiple directories. -Note that every operation on a cluster always has to be performed from the directory associated with its workspace.

-

You may copy files from the workspace to other locations, -but you shouldn't move or delete them while the cluster is still being used. -The Constellation CLI takes care of managing the workspace. -Only when a cluster was terminated, and you are sure the files aren't needed anymore, should you remove a workspace.

-

Cluster creation process​

-

To allow for fine-grained configuration of your cluster and cloud environment, Constellation supports an extensive configuration file with strong defaults. Generating the configuration file is typically the first thing you do in the workspace.

-

Altogether, the following files are generated during the creation of a Constellation cluster and stored in the current workspace:

-
    -
  • a configuration file
    • -
  • a state file
    • -
  • a Base64-encoded master secret
    • -
  • Terraform artifacts, stored in subdirectories
    • -
  • a Kubernetes kubeconfig file.
    • -
-

After the initialization of your cluster, the CLI will provide you with a Kubernetes kubeconfig file. -This file grants you access to your Kubernetes cluster and configures the kubectl tool. -In addition, the cluster's identifier is returned and stored in the state file.

-

  4. The Bootstrapper waits until it either receives an initialization request or discovers an initialized cluster
    5. -
  5. The CLI then connects to the Bootstrapper of a selected node, sends the configuration, and initiates the initialization of the cluster
    6. -
  6. The Bootstrapper of that node initializes the Kubernetes cluster and deploys the other Constellation microservices including the JoinService
    7. -
  7. Subsequently, the Bootstrappers of the other nodes discover the initialized cluster and send join requests to the JoinService
    8. -
  8. As part of the join request each node includes an attestation statement of its boot measurements as authentication
    9. -
  9. The JoinService verifies the attestation statements and joins the nodes to the Kubernetes cluster
    10. -
  10. This process is repeated for every node joining the cluster later (e.g., through autoscaling)
    11. -
-

Post-installation configuration​

-

Post-installation the CLI provides a configuration for accessing the cluster using the Kubernetes API. -The kubeconfig file provides the credentials and configuration for connecting and authenticating to the API server. -Once configured, orchestrate the Kubernetes cluster via kubectl.

-

After the initialization, the CLI will present you with a couple of tokens:

-
    -
  • The master secret (stored in the constellation-mastersecret.json file by default)
    • -
  • The clusterID of your cluster in Base64 encoding
    • -
-

You can read more about these values and their meaning in the guide on cluster identity.

-

The master secret must be kept secret and can be used to recover your cluster. -Instead of managing this secret manually, you can use your key management solution of choice with Constellation.

-

The clusterID uniquely identifies a cluster and can be used to verify your cluster.

-

Upgrades​

-

Constellation images and microservices may need to be upgraded to new versions during the lifetime of a cluster. -Constellation implements a rolling update mechanism ensuring no downtime of the control or data plane. -You can upgrade a Constellation cluster with a single operation by using the CLI. -For step-by-step instructions on how to do this, refer to Upgrade your cluster.

-

Attestation of upgrades​

-

With every new image, corresponding measurements are released. -During an update procedure, the CLI provides new measurements to the JoinService securely. -New measurements for an updated image are automatically pulled and verified by the CLI following the supply chain security concept of Constellation. -The attestation section describes in detail how these measurements are then used by the JoinService for the attestation of nodes.

Overview

-

Constellation is a cloud-based confidential orchestration platform. -The foundation of Constellation is Kubernetes and therefore shares the same technology stack and architecture principles. -To learn more about Constellation and Kubernetes, see product overview.

-

About orchestration and updates​

-

As a cluster administrator, you can use the Constellation CLI to install and deploy a cluster. -Updates are provided in accordance with the support policy.

-

About microservices and attestation​

-

Constellation manages the nodes and network in your cluster. All nodes are bootstrapped by the Bootstrapper. They're verified and authenticated by the JoinService before being added to the cluster and the network. Finally, the entire cluster can be verified via the VerificationService using remote attestation.

-

About node images and verified boot​

-

Constellation comes with operating system images for Kubernetes control-plane and worker nodes. -They're highly optimized for running containerized workloads and specifically prepared for running inside confidential VMs. -You can learn more about the images and how verified boot ensures their integrity during boot and beyond.

-

About key management and cryptographic primitives​

-

Encryption of data at-rest, in-transit, and in-use is the fundamental building block for confidential computing and Constellation. Learn more about the keys and cryptographic primitives used in Constellation, encrypted persistent storage, and network encryption.

-

About observability​

-

Observability in Kubernetes refers to the capability to troubleshoot issues using telemetry signals such as logs, metrics, and traces. -In the realm of Confidential Computing, it's crucial that observability aligns with confidentiality, necessitating careful implementation. -Learn more about the observability capabilities in Constellation.

Version: 2.24

Versions and support policy

-

All components of Constellation use a three-digit version number of the form v<MAJOR>.<MINOR>.<PATCH>. -The components are released in lock step, usually on the first Tuesday of every month. This release primarily introduces new features, but may also include security or performance improvements. The MINOR version will be incremented as part of this release.

-

Additional PATCH releases may be created on demand, to fix security issues or bugs before the next MINOR release window.

-

New releases are published on GitHub.

-

Kubernetes support policy​

-

Constellation is aligned to the version support policy of Kubernetes, and therefore usually supports the most recent three minor versions. -When a new minor version of Kubernetes is released, support is added to the next Constellation release, and that version then supports four Kubernetes versions. -Subsequent Constellation releases drop support for the oldest (and deprecated) Kubernetes version.

-

The following Kubernetes versions are currently supported:

-
    -
  • v1.30.14
    • -
  • v1.31.12
    • -
  • v1.32.8

The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red).

    Basics

    📄️ Security benefits

    Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

    Deploying Filestash

    -

    Filestash is a web frontend for different storage backends, including S3. -It's a useful application to showcase s3proxy in action.

    -
      -
    1. Deploy s3proxy as described in Deployment.
      2. -
    2. Create a deployment file for Filestash with one pod:

    The pod spec includes the hostAliases key, which adds an entry to the pod's /etc/hosts. -The entry forwards all requests for any of the currently defined AWS regions to the Kubernetes service s3proxy-service. -If you followed the s3proxy Deployment guide, this service points to a s3proxy pod.

    -

    The deployment specifies all regions explicitly to prevent accidental data leaks. -If one of your buckets were located in a region that's not part of the hostAliases key, traffic towards those buckets would not be redirected to s3proxy. -Similarly, if you want to exclude data for specific regions from going through s3proxy you can remove those regions from the deployment.

    -

    The spec also includes a volume mount for the TLS certificate and adds it to the pod's certificate trust store. -The volume is called ca-cert. -The key ca.crt of that volume is mounted to /etc/ssl/certs/kube-ca.crt, which is the default certificate trust store location for that container's OpenSSL library. -Not adding the CA certificate will result in TLS authentication errors.

    -
      -
    1. Apply the file: kubectl apply -f deployment-filestash.yaml
      2. -
    -

    Afterward, you can use a port forward to access the Filestash pod: -kubectl port-forward pod/$(kubectl get pod --selector='app=filestash' -o=jsonpath='{.items[*].metadata.name}') 8334:8334

    -
      -
    1. -

      After browsing to localhost:8443, Filestash will ask you to set an administrator password. -After setting it, you can directly leave the admin area by clicking the blue cloud symbol in the top left corner. -Subsequently, you can select S3 as storage backend and enter your credentials. -This will bring you to an overview of your buckets. -If you want to deploy Filestash in production, take a look at its documentation.

      -
      2. -
    2. -

      To see the logs of s3proxy intercepting requests made to S3, run: kubectl logs -f pod/$(kubectl get pod --selector='app=s3proxy' -o=jsonpath='{.items[*].metadata.name}') -Look out for log messages labeled intercepting. -There is one such log message for each message that's encrypted, decrypted, or blocked.

      -
      3. -
    3. -

      Once you have uploaded a file with Filestash, you should be able to view the file in Filestash. -However, if you go to the AWS S3 Web UI and download the file you just uploaded in Filestash, you won't be able to read it. -Another way to spot encrypted files without downloading them is to click on a file, scroll to the Metadata section, and look for the header named x-amz-meta-constellation-encryption. -This header holds the encrypted data encryption key of the object and is only present on objects that are encrypted by s3proxy.

    Horizontal Pod Autoscaling

    -

    This example demonstrates Constellation's autoscaling capabilities. It's based on the Kubernetes HorizontalPodAutoscaler Walkthrough. During the following steps, Constellation will spawn new VMs on demand, verify them, add them to the cluster, and delete them again when the load has settled down.

    -

    Requirements​

    -

    The cluster needs to be initialized with Kubernetes 1.23 or later. In addition, autoscaling must be enabled to enable Constellation to assign new nodes dynamically.

    -

    Just for this example specifically, the cluster should have as few worker nodes in the beginning as possible. Start with a small cluster with only one low-powered node for the control-plane node and one low-powered worker node.

    -
    info

    We tested the example using instances of types Standard_DC4as_v5 on Azure and n2d-standard-4 on GCP.

    -

    Setup​

    -
      -
    1. -

      Install the Kubernetes Metrics Server:

      -
      kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
      -
      2. -
    2. -

      Deploy the HPA example server that's supposed to be scaled under load.

      -

      This manifest is similar to the one from the Kubernetes HPA walkthrough, but with increased CPU limits and requests to facilitate the triggering of node scaling events.

      Create a HorizontalPodAutoscaler.

      -

      Set an average CPU usage across all Pods of 20% to see one additional worker node being created later. Note that the CPU usage isn't related to the host CPU usage, but rather to the requested CPU capacities (20% of 600 milli-cores CPU across all Pods). See the original tutorial for more information on the HPA configuration.

      -
      kubectl autoscale deployment php-apache --cpu-percent=20 --min=1 --max=10
      -
      4. -
    4. -

      Create a Pod that generates load on the server:

      -
      kubectl run -i --tty load-generator --rm --image=busybox:1.28 --restart=Never -- /bin/sh -c "while true; do wget -q -O- http://php-apache; done"
      -
      5. -
    5. -

      Wait a few minutes until new nodes are added to the cluster. You can monitor the state of the HorizontalPodAutoscaler, the list of nodes, and the behavior of the autoscaler.

      -
      6. -
    6. -

      To stop the load generator, press CTRL+C and run:

      -
      kubectl delete pod load-generator
      -
      7. -
    7. -

      The cluster-autoscaler checks every few minutes if nodes are underutilized. It will taint such candidates for removal and wait additional 10 minutes before the nodes are eventually removed and deallocated. The whole process can take about 20 minutes.

      -
      8. -
    -

    Monitoring​

    -
    tip

    For better observability, run the listed commands in different tabs in your terminal.

    -

    You can watch the status of the HorizontalPodAutoscaler with the current CPU usage, the target CPU limit, and the number of replicas created with:

    -
    kubectl get hpa php-apache --watch
    -

    From time to time compare the list of nodes to check the behavior of the autoscaler:

    -
    kubectl get nodes
    -

    For deeper insights, see the logs of the autoscaler Pod, which contains more details about the scaling decision process:

    -
    kubectl logs -f deployment/constellation-cluster-autoscaler -n kube-system

    First steps with a local cluster

    -

    A local cluster lets you deploy and test Constellation without a cloud subscription. -You have two options:

    -
      -
    • Use MiniConstellation to automatically deploy a two-node cluster.
      • -
    • For more fine-grained control, create the cluster using the QEMU provider.
      • -
    -

    Both options use virtualization to create a local cluster with control-plane nodes and worker nodes. They don't require hardware with Confidential VM (CVM) support. For attestation, they currently use a software-based vTPM provided by KVM/QEMU.

    -

    You need an x64 machine with a Linux OS. -You can use a VM, but it needs nested virtualization.

    -

    Prerequisites​

    -
      -
    • Machine requirements: -
        -
      • An x86-64 CPU with at least 4 cores (6 cores are recommended)
        • -
      • At least 4 GB RAM (6 GB are recommended)
        • -
      • 20 GB of free disk space
        • -
      • Hardware virtualization enabled in the BIOS/UEFI (often referred to as Intel VT-x or AMD-V/SVM) / nested-virtualization support when using a VM
        • -
      -
      • -
    • Software requirements: - -
      • -
    -

    Software installation on Ubuntu​

    -
    # install Docker
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
    echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

    sudo apt install docker-ce
    # install other dependencies
    sudo apt install xsltproc

    sudo install constellation-linux-amd64 /usr/local/bin/constellation
    # do not drop forwarded packages
    sudo iptables -P FORWARD ACCEPT
    -

    Create a cluster​

    -

    With the constellation mini command, you can deploy and test Constellation locally. This mode is called MiniConstellation. Conceptually, MiniConstellation is similar to MicroK8s, K3s, and minikube.

    caution

    MiniConstellation has specific soft- and hardware requirements such as a Linux OS running on an x86-64 CPU. Pay attention to all prerequisites when setting up.

    note

    Since MiniConstellation runs on your local system, cloud features such as load balancing, -attaching persistent storage, or autoscaling aren't available.

    The following creates your MiniConstellation cluster (may take up to 10 minutes to complete):

    constellation mini up

    This will configure your current directory as the workspace for this cluster. -All constellation commands concerning this cluster need to be issued from this directory.

    -

    Connect to the cluster​

    -

    Your cluster initially consists of a single control-plane node:

    -
    $ kubectl get nodes
    NAME              STATUS   ROLES           AGE   VERSION
    control-plane-0   Ready    control-plane   66s   v1.24.6
    -

    Additional nodes will request to join the cluster shortly. Before each additional node is allowed to join the cluster, its state is verified using remote attestation by the JoinService. -If verification passes successfully, the new node receives keys and certificates to join the cluster.

    -

    You can follow this process by viewing the logs of the JoinService:

    -
    $ kubectl logs -n kube-system daemonsets/join-service -f
    {"level":"INFO","ts":"2022-10-14T09:32:20Z","caller":"cmd/main.go:48","msg":"Constellation Node Join Service","version":"2.1.0","cloudProvider":"qemu"}
    {"level":"INFO","ts":"2022-10-14T09:32:20Z","logger":"validator","caller":"watcher/validator.go:96","msg":"Updating expected measurements"}
    ...
    -

    Once all nodes have joined your cluster, it may take a couple of minutes for all resources to become available. -You can check on the state of your cluster by running the following:

    -
    $ kubectl get nodes
    NAME              STATUS   ROLES           AGE     VERSION
    control-plane-0   Ready    control-plane   2m59s   v1.24.6
    worker-0          Ready    <none>          32s     v1.24.6
    -

    Deploy a sample application​

    -
      -
    1. Deploy the emojivoto app
      2. -
    -
    kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
    -
      -
    1. Expose the frontend service locally
      2. -
    -
    kubectl wait --for=condition=available --timeout=60s -n emojivoto --all deployments
    kubectl -n emojivoto port-forward svc/web-svc 8080:80 &
    curl http://localhost:8080
    kill %1
    -

    Terminate your cluster​

    -

    Once you are done, you can clean up the created resources using the following command:

    constellation mini down

    This will destroy your cluster and clean up your workspace. -The VM image and cluster configuration file (constellation-conf.yaml) will be kept and may be reused to create new clusters.

    -

    Troubleshooting​

    -

    Make sure to use the latest release and check out the known issues.

    -

    VMs have no internet access / CLI remains in "Initializing cluster" state​

    -

    iptables rules may prevent your VMs from accessing the internet. -Make sure your rules aren't dropping forwarded packages.

    -

    List your rules:

    -
    sudo iptables -S
    -

    The output may look similar to the following:

    -
    -P INPUT ACCEPT
    -P FORWARD DROP
    -P OUTPUT ACCEPT
    -N DOCKER
    -N DOCKER-ISOLATION-STAGE-1
    -N DOCKER-ISOLATION-STAGE-2
    -N DOCKER-USER
    -

    If your FORWARD chain is set to DROP, you need to update your rules:

    First steps with Constellation

    -

    The following steps guide you through the process of creating a cluster and deploying a sample app. This example assumes that you have successfully installed and set up Constellation, -and have access to a cloud subscription.

    -
    tip

    If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

    -
    note

    If you encounter any problem with the following steps, make sure to use the latest release and check out the known issues.

    -

    Create a cluster​

    -
      -
    1. -

      Create the configuration file and state file for your cloud provider. If you are following the steps of this guide, there is no need to edit the file.

      -
      constellation config generate aws
      -
      2. -
    2. -

      Create your IAM configuration.

      -
      constellation iam create aws --zone=us-east-2a --prefix=constellTest --update-config

      This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created. It also updates the configuration file constellation-conf.yaml in your current directory with the IAM values filled in.

      Depending on the attestation variant selected on config generation, different regions are available. -AMD SEV-SNP machines (requires the default attestation variant awsSEVSNP) are currently available in the following regions:

        -
      • eu-west-1
        • -
      • us-east-2
        • -

      You can find a list of regions that support AMD SEV-SNP in AWS's documentation.

      NitroTPM machines (requires the attestation variant awsNitroTPM) are available in all regions. -Constellation OS images are currently replicated to the following regions:

        -
      • eu-central-1
        • -
      • eu-west-1
        • -
      • eu-west-3
        • -
      • us-east-2
        • -
      • ap-south-1
        • -

      If you require the OS image to be available in another region, let us know.

      You can find a list of all regions in AWS's documentation.

      -
      tip

      To learn about all options you have for managing IAM resources and Constellation configuration, see the Configuration workflow.

      -
      3. -
    -
      -
    1. -

      Create the cluster. constellation apply uses options set in constellation-conf.yaml. -If you want to manually manage your cloud resources, for example by using Terraform, follow the corresponding instructions in the Create workflow.

      -
      tip

      On Azure, you may need to wait 15+ minutes at this point for role assignments to propagate.

      -
      constellation apply -y
      -

      This should look similar to the following:

      -
      $ constellation apply -y
      Checking for infrastructure changes
      The following Constellation cluster will be created:
        3 control-plane nodes of type n2d-standard-4 will be created.
        1 worker node of type n2d-standard-4 will be created.

      You can now connect to your cluster by executing:
              export KUBECONFIG="$PWD/constellation-admin.conf"
      -

      The cluster's identifier will be different in your output. -Keep constellation-mastersecret.json somewhere safe. -This will allow you to recover your cluster in case of a disaster.

      -
      info

      Depending on your CSP and region, constellation apply may take 10+ minutes to complete.

      -
      2. -
    2. -

      Configure kubectl.

      -
      export KUBECONFIG="$PWD/constellation-admin.conf"
      -
      3. -
    -

    Deploy a sample application​

    -
      -
    1. -

      Deploy the emojivoto app

      -
      kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
      -
      2. -
    2. -

      Expose the frontend service locally

      -
      kubectl wait --for=condition=available --timeout=60s -n emojivoto --all deployments
      kubectl -n emojivoto port-forward svc/web-svc 8080:80 &
      curl http://localhost:8080
      kill %1
      -
      3. -
    -

    Terminate your cluster​

    -

    Use the CLI to terminate your cluster. If you manually used Terraform to manage your cloud resources, follow the corresponding instructions in the Terminate workflow.

    -
    constellation terminate
    -

    This should give the following output:

    -
    $ constellation terminate
    You are about to terminate a Constellation cluster.
    All of its associated resources will be DESTROYED.
    This action is irreversible and ALL DATA WILL BE LOST.
    Do you want to continue? [y/n]:
    -

    Confirm with y to terminate the cluster:

    -
    Terminating ...
    Your Constellation cluster was terminated successfully.
    -

    Optionally, you can also delete your IAM resources.

    Installation and setup

    -

    Constellation runs entirely in your cloud environment and can be controlled via a dedicated command-line interface (CLI) or a Terraform provider.

    -

    Prerequisites​

    -

    Make sure the following requirements are met:

    -
      -
    • Your machine is running Linux, macOS, or Windows
      • -
    • You have admin rights on your machine
      • -
    • kubectl is installed
      • -
    • Your CSP is Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), or STACKIT
      • -
    -

    Install the Constellation CLI​

    -
    tip

    If you prefer to use Terraform, you can alternatively use the Terraform provider to manage the cluster's lifecycle.

    -

    The CLI executable is available at GitHub. -Install it with the following commands:

    -
      -
    1. Download the CLI:
      2. -
    curl -LO https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64
      -
    1. -

      Verify the signature (optional)

      -
      2. -
    2. -

      Install the CLI to your PATH:

      -
      3. -
    sudo install constellation-linux-amd64 /usr/local/bin/constellation
    -
    tip

    The CLI supports autocompletion for various shells. To set it up, run constellation completion and follow the given steps.

    -

    Set up cloud credentials​

    -

    Constellation makes authenticated calls to the CSP API. Therefore, you need to set up Constellation with the credentials for your CSP.

    -
    tip

    If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

    -

    Required permissions​

    -

    To set up a Constellation cluster, you need to perform two tasks that require permissions: create the infrastructure and create roles for cluster nodes. Both of these actions can be performed by different users, e.g., an administrator to create roles and a DevOps engineer to create the infrastructure.

    To create the IAM configuration for Constellation, you need the following permissions:

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "ec2:DescribeAccountAttributes",
                    "iam:AddRoleToInstanceProfile",
                    "iam:AttachRolePolicy",
                    "iam:CreateInstanceProfile",
                    "iam:CreatePolicy",
                    "iam:CreateRole",
                    "iam:DeleteInstanceProfile",
                    "iam:DeletePolicy",
                    "iam:DeletePolicyVersion",
                    "iam:DeleteRole",
                    "iam:DetachRolePolicy",
                    "iam:GetInstanceProfile",
                    "iam:GetPolicy",
                    "iam:GetPolicyVersion",
                    "iam:GetRole",
                    "iam:ListAttachedRolePolicies",
                    "iam:ListInstanceProfilesForRole",
                    "iam:ListPolicyVersions",
                    "iam:ListRolePolicies",
                    "iam:PassRole",
                    "iam:RemoveRoleFromInstanceProfile",
                    "sts:GetCallerIdentity"
                ],
                "Resource": "*"
            }
        ]
    }

    The built-in AdministratorAccess policy is a superset of these permissions.

    To create a Constellation cluster, see the permissions of main.tf.

    The built-in PowerUserAccess policy is a superset of these permissions.

    Follow Amazon's guide on understanding and managing policies.

    -

    Authentication​

    -

    You need to authenticate with your CSP. The following lists the required steps for testing and production environments.

    -
    note

    The steps for a testing environment are simpler. However, they may expose secrets to the CSP. If in doubt, follow the production steps.

    -

    Testing

    You can use the AWS CloudShell. Make sure you are authorized to use it.

    Production

    Use the latest version of the AWS CLI on a trusted machine:

    aws configure

    Options and first steps are described in the AWS CLI documentation.

    -

    Next steps​

    -

    You are now ready to deploy your first confidential Kubernetes cluster and application.

    Using Constellation via Cloud Marketplaces

    -

    Constellation is available through the Marketplaces of AWS, Azure, GCP, and STACKIT. This allows you to create self-managed Constellation clusters that are billed on a pay-per-use basis (hourly, per vCPU) with your CSP account. You can still get direct support by Edgeless Systems. For more information, please contact us.

    -

    This document explains how to run Constellation with the dynamically billed cloud marketplace images.

    -

    To use Constellation's marketplace images, ensure that you are subscribed to the marketplace offering through the web portal.

    Then, enable the use of marketplace images in your Constellation constellation-conf.yaml config file:

    yq eval -i ".provider.aws.useMarketplaceImage = true" constellation-conf.yaml
    -

    Ensure that the cluster uses an official release image version (i.e., .image=vX.Y.Z in the constellation-conf.yaml file).

    -

    From there, you can proceed with the cluster creation as usual.

    Introduction

    -
    Maintenance Notice

    Constellation is no longer actively maintained by Edgeless Systems.

    This project is no longer receiving updates or support from Edgeless Systems. The repository and documentation remain available for archival purposes and community use.

    -

    Welcome to the documentation of Constellation! Constellation is a Kubernetes engine that aims to provide the best possible data security.

    -

    Constellation concept

    -

    Constellation shields your entire Kubernetes cluster from the underlying cloud infrastructure. Everything inside is always encrypted, including at runtime in memory. For this, Constellation leverages a technology called confidential computing and more specifically Confidential VMs.

    -
    tip

    See the 📄whitepaper for more information on confidential computing.

    -

    Goals​

    -

    From a security perspective, Constellation is designed to keep all data always encrypted and to prevent any access from the underlying (cloud) infrastructure. This includes access from datacenter employees, privileged cloud admins, and attackers coming through the infrastructure. Such attackers could be malicious co-tenants escalating their privileges or hackers who managed to compromise a cloud server.

    -

    From a DevOps perspective, Constellation is designed to work just like what you would expect from a modern Kubernetes engine.

    -

    Use cases​

    -

    Constellation provides unique security features and benefits. The core use cases are:

    -
      -
    • Increasing the overall security of your clusters
      • -
    • Increasing the trustworthiness of your SaaS offerings
      • -
    • Moving sensitive workloads from on-prem to the cloud
      • -
    • Meeting regulatory requirements
      • -
    -

    Next steps​

    -

    You can learn more about the concept of Confidential Kubernetes, features, security benefits, and performance of Constellation in the Basics section. To jump right into the action head to Getting started.

    Attestation

    -

    This page explains Constellation's attestation process and highlights the cornerstones of its trust model.

    -

    Terms​

    -

    The following lists terms and concepts that help to understand the attestation concept of Constellation.

    -

    Trusted Platform Module (TPM)​

    -

    A TPM chip is a dedicated tamper-resistant crypto-processor. -It can securely store artifacts such as passwords, certificates, encryption keys, or runtime measurements (more on this below). -When a TPM is implemented in software, it's typically called a virtual TPM (vTPM).

    -

    Runtime measurement​

    -

    A runtime measurement is a cryptographic hash of the memory pages of a so called runtime component. Runtime components of interest typically include a system's bootloader or OS kernel.

    -

    Platform Configuration Register (PCR)​

    -

    A Platform Configuration Register (PCR) is a memory location in the TPM that has some unique properties. -To store a new value in a PCR, the existing value is extended with a new value as follows:

    -
    PCR[N] = HASHalg( PCR[N] || ArgumentOfExtend )
    -

    The PCRs are typically used to store runtime measurements. -The new value of a PCR is always an extension of the existing value. -Thus, storing the measurements of multiple components into the same PCR irreversibly links them together.

    -

    Measured boot​

    -

    Measured boot builds on the concept of chained runtime measurements. -Each component in the boot chain loads and measures the next component into the PCR before executing it. -By comparing the resulting PCR values against trusted reference values, the integrity of the entire boot chain and thereby the running system can be ensured.

    -

    Remote attestation (RA)​

    -

    Remote attestation is the process of verifying certain properties of an application or platform, such as integrity and confidentiality, from a remote location. -In the case of a measured boot, the goal is to obtain a signed attestation statement on the PCR values of the boot measurements. -The statement can then be verified and compared to a set of trusted reference values. -This way, the integrity of the platform can be ensured before sharing secrets with it.

    -

    Confidential virtual machine (CVM)​

    -

    Confidential computing (CC) is the protection of data in-use with hardware-based trusted execution environments (TEEs). -With CVMs, TEEs encapsulate entire virtual machines and isolate them against the hypervisor, other VMs, and direct memory access. -After loading the initial VM image into encrypted memory, the hypervisor calls for a secure processor to measure these initial memory pages. -The secure processor locks these pages and generates an attestation report on the initial page measurements. -CVM memory pages are encrypted with a key that resides inside the secure processor, which makes sure only the guest VM can access them. -The attestation report is signed by the secure processor and can be verified using remote attestation via the certificate authority of the hardware vendor. -Such an attestation statement guarantees the confidentiality and integrity of a CVM.

    -

    Attested TLS (aTLS)​

    -

    In a CC environment, attested TLS (aTLS) can be used to establish secure connections between two parties using the remote attestation features of the CC components.

    -

    aTLS modifies the TLS handshake by embedding an attestation statement into the TLS certificate. -Instead of relying on a certificate authority, aTLS uses this attestation statement to establish trust in the certificate.

    -

    The protocol can be used by clients to verify a server certificate, by a server to verify a client certificate, or for mutual verification (mutual aTLS).

    -

    Overview​

    -

    The challenge for Constellation is to lift a CVM's attestation statement to the Kubernetes software layer and make it end-to-end verifiable. -From there, Constellation needs to expand the attestation from a single CVM to the entire cluster.

    -

    The JoinService and VerificationService are where all runs together. -Internally, the JoinService uses remote attestation to securely join CVM nodes to the cluster. -Externally, the VerificationService provides an attestation statement for the cluster's CVMs and configuration.

    -

    The following explains the details of both steps.

    -

    Node attestation​

    -

    The idea is that Constellation nodes should have verifiable integrity from the CVM hardware measurement up to the Kubernetes software layer. -The solution is a verifiable boot chain and an integrity-protected runtime environment.

    -

    Constellation uses measured boot within CVMs, measuring each component in the boot process before executing it. -Outside of CC, this is usually implemented via TPMs. -CVM technologies differ in how they implement runtime measurements, but the general concepts are similar to those of a TPM. -For simplicity, TPM terminology like PCR is used in the following.

    -

    When a Constellation node image boots inside a CVM, measured boot is used for all stages and components of the boot chain. -This process goes up to the root filesystem. -The root filesystem is mounted read-only with integrity protection. -For the details on the image and boot stages see the image architecture documentation. -Any changes to the image will inevitably also change the corresponding PCR values. -To create a node attestation statement, the Constellation image obtains a CVM attestation statement from the hardware. -This includes the runtime measurements and thereby binds the measured boot results to the CVM hardware measurement.

    -

    In addition to the image measurements, Constellation extends a PCR during the initialization phase that irrevocably marks the node as initialized. -The measurement is created using the clusterID, tying all future attestation statements to this ID. -Thereby, an attestation statement is unique for every cluster and a node can be identified unambiguously as being initialized.

    -

    To verify an attestation, the hardware's signature and a statement are verified first to establish trust in the contained runtime measurements. -If successful, the measurements are verified against the trusted values of the particular Constellation release version. -Finally, the measurement of the clusterID can be compared by calculating it with the master secret.

    -

    Runtime measurements​

    -

    Constellation uses runtime measurements to implement the measured boot approach. -As stated above, the underlying hardware technology and guest firmware differ in their implementations of runtime measurements. -The following gives a detailed description of the available measurements in the different cloud environments.

    -

    The runtime measurements consist of two types of values:

    -
      -
    • -

      Measurements produced by the cloud infrastructure and firmware of the CVM: -These are measurements of closed-source firmware and other values controlled by the cloud provider. -While not being reproducible for the user, some of them can be compared against previously observed values. -Others may change frequently and aren't suitable for verification. -The signed image measurements include measurements that are known, previously observed values.

      -
      • -
    • -

      Measurements produced by the Constellation bootloader and boot chain: -The Constellation Bootloader takes over from the CVM firmware and measures the rest of the boot chain. -The Constellation Bootstrapper is the first user mode component that runs in a Constellation image. -It extends PCR registers with the IDs of the cluster marking a node as initialized.

      -
      • -
    -

    Constellation allows to specify in the config which measurements should be enforced during the attestation process. -Enforcing non-reproducible measurements controlled by the cloud provider means that changes in these values require manual updates to the cluster's config. -By default, Constellation only enforces measurements that are stable values produced by the infrastructure or by Constellation directly.

    -

    Constellation uses the vTPM (NitroTPM) feature of the AWS Nitro System on AWS for runtime measurements.

    The vTPM adheres to the TPM 2.0 specification. -The VMs are attested by obtaining signed PCR values over the VM's boot configuration from the TPM and comparing them to a known, good state (measured boot).

    The following table lists all PCR values of the vTPM and the measured components. -It also lists what components of the boot chain did the measurements and if the value is reproducible and verifiable. -The latter means that the value can be generated offline and compared to the one in the vTPM.

    CVM verification​

    -

    To verify the integrity of the received attestation statement, a chain of trust from the CVM technology to the interface providing the statement has to be established. -For verification of the CVM technology, Constellation may expose additional options in its config file.

    -

    On AWS, AMD SEV-SNP is used to provide runtime encryption to the VMs. -An SEV-SNP attestation report is used to establish trust in the VM. -You may customize certain parameters for verification of the attestation statement using the Constellation config file.

      -
    • -

      TCB versions

      -

      You can set the minimum version numbers of components in the SEV-SNP TCB. -Use the latest versions to enforce that only machines with the most recent firmware updates are allowed to join the cluster. -Alternatively, you can set a lower minimum version to allow slightly out-of-date machines to still be able to join the cluster.

      -
      • -
    • -

      AMD Root Key Certificate

      -

      This certificate is the root of trust for verifying the SEV-SNP certificate chain.

      -
      • -
    • -

      AMD Signing Key Certificate

      -

      This is the intermediate certificate for verifying the SEV-SNP report's signature. -If it's not specified, the CLI fetches it from the AMD key distribution server.

      -
      • -
    -

    Cluster attestation​

    -

    Cluster-facing, Constellation's JoinService verifies each node joining the cluster given the configured ground truth runtime measurements. -User-facing, the VerificationService provides an interface to verify a node using remote attestation. -By verifying the first node during the initialization and configuring the ground truth measurements that are subsequently enforced by the JoinService, the whole cluster is verified in a transitive way.

    -

    Cluster-facing attestation​

    -

    The JoinService is provided with the runtime measurements of the whitelisted Constellation image version as the ground truth. -During the initialization and the cluster bootstrapping, each node connects to the JoinService using aTLS. -During the handshake, the node transmits an attestation statement including its runtime measurements. -The JoinService verifies that statement and compares the measurements against the ground truth. -For details of the initialization process check the microservice descriptions.

    -

    After the initialization, every node updates its runtime measurements with the clusterID value, marking it irreversibly as initialized. -When an initialized node tries to join another cluster, its measurements inevitably mismatch the measurements of an uninitialized node and it will be declined.

    -

    User-facing attestation​

    -

    The VerificationService provides an endpoint for obtaining its hardware-based remote attestation statement, which includes the runtime measurements. -A user can verify this statement and compare the measurements against the configured ground truth and, thus, verify the identity and integrity of all Constellation components and the cluster configuration. Subsequently, the user knows that the entire cluster is in the expected state and is trustworthy.

    -

    Putting it all together​

    -

    This section puts the aforementioned concepts together and illustrate how trust into a Constellation cluster is established and maintained.

    -

    CLI and node images​

    -

    It all starts with the CLI executable. The CLI is signed by Edgeless Systems. To ensure non-repudiability for CLI releases, Edgeless Systems publishes corresponding signatures to the public ledger of the sigstore project. There's a step-by-step guide on how to verify CLI signatures based on sigstore.

    -

    The CLI contains the latest runtime measurements of the Constellation node image for all supported cloud platforms. In case a different version of the node image is to be used, the corresponding runtime measurements can be fetched using the CLI's fetch-measurements command. This command downloads the runtime measurements and the corresponding signature from cdn.confidential.cloud. See for example the following files corresponding to node image v2.16.3:

    - -

    The CLI contains the long-term public key of Edgeless Systems to verify the signature of downloaded runtime measurements.

    -

    Cluster creation​

    -

    When a cluster is created, the CLI automatically verifies the runtime measurements of the first node using remote attestation. Based on this, the CLI and the first node set up a temporary TLS connection. This aTLS connection is used for two things:

    -
      -
    1. The CLI sends the master secret of the to-be-created cluster to the CLI. The master secret is generated by the first node.
      2. -
    2. The first node sends a kubeconfig file with Kubernetes credentials to the CLI.
      3. -
    -

    After this, the aTLS connection is closed and the first node bootstraps the Kubernetes cluster. All subsequent interactions between the CLI and the cluster go via the Kubernetes API server running inside the cluster. The CLI (and other tools like kubectl) use the credentials referenced by the kubeconfig file to authenticate themselves towards the Kubernetes API server and to establish a mTLS connection.

    -

    The CLI connects to the Kubernetes API to write the runtime measurements for the applicable node image to etcd. The JoinService uses these runtime measurements to verify all nodes that join the cluster subsequently.

    -

    Chain of trust​

    -

    In summary, there's a chain of trust based on cryptographic signatures that goes from the user to the cluster via the CLI. This is illustrated in the following diagram.

    - -

    Upgrades​

    -

    Whenever a cluster is upgraded to a new version of the node image, the CLI sends the corresponding runtime measurements via the Kubernetes API server. The new runtime measurements are stored in etcd within the cluster and replace any previous runtime measurements. The new runtime measurements are then used automatically by the JoinService for the verification of new nodes.

    Encrypted persistent storage

    -

    Confidential VMs provide runtime memory encryption to protect data in use. -In the context of Kubernetes, this is sufficient for the confidentiality and integrity of stateless services. -Consider a front-end web server, for example, that keeps all connection information cached in main memory. -No sensitive data is ever written to an insecure medium. -However, many real-world applications need some form of state or data-lake service that's connected to a persistent storage device and requires encryption at rest. -As described in Use persistent storage, cloud service providers (CSPs) use the container storage interface (CSI) to make their storage solutions available to Kubernetes workloads. -These CSI storage solutions often support some sort of encryption. -For example, Google Cloud encrypts data at rest by default, without any action required by the customer.

    -

    Cloud provider-managed encryption​

    -

    CSP-managed storage solutions encrypt the data in the cloud backend before writing it physically to disk. -In the context of confidential computing and Constellation, the CSP and its managed services aren't trusted. -Hence, cloud provider-managed encryption protects your data from offline hardware access to physical storage devices. -It doesn't protect it from anyone with infrastructure-level access to the storage backend or a malicious insider in the cloud platform. -Even with "bring your own key" or similar concepts, the CSP performs the encryption process with access to the keys and plaintext data.

    -

    In the security model of Constellation, securing persistent storage and thereby data at rest requires that all cryptographic operations are performed inside a trusted execution environment. -Consequently, using CSP-managed encryption of persistent storage usually isn't an option.

    -

    Constellation-managed encryption​

    -

    Constellation provides CSI drivers for storage solutions in all major clouds with built-in encryption support. -Block storage provisioned by the CSP is mapped using the dm-crypt, and optionally the dm-integrity, kernel modules, before it's formatted and accessed by the Kubernetes workloads. -All cryptographic operations happen inside the trusted environment of the confidential Constellation node.

    -

    Note that for integrity-protected disks, volume expansion isn't supported.

    -

    By default the driver uses data encryption keys (DEKs) issued by the Constellation KeyService. -The DEKs are in turn derived from the Constellation's key encryption key (KEK), which is directly derived from the master secret. -This is the recommended mode of operation, and also requires the least amount of setup by the cluster administrator.

    -

    Alternatively, the driver can be configured to use a key management system to store and access KEKs and DEKs.

    -

    Refer to keys and cryptography for more details on key management in Constellation.

    -

    Once deployed and configured, the CSI driver ensures transparent encryption and integrity of all persistent volumes provisioned via its storage class. -Data at rest is secured without any additional actions required by the developer.

    -

    Cryptographic algorithms​

    -

    This section gives an overview of the libraries, cryptographic algorithms, and their configurations, used in Constellation's CSI drivers.

    -

    dm-crypt​

    -

    To interact with the dm-crypt kernel module, Constellation uses libcryptsetup. -New devices are formatted as LUKS2 partitions with a sector size of 4096 bytes. -The used key derivation function is Argon2id with the recommended parameters for memory-constrained environments of 3 iterations and 64 MiB of memory, utilizing 4 parallel threads. -For encryption Constellation uses AES in XTS-Plain64. The key size is 512 bit.

    -

    dm-integrity​

    -

    To interact with the dm-integrity kernel module, Constellation uses libcryptsetup. -When enabled, the used data integrity algorithm is HMAC with SHA256 as the hash function. -The tag size is 32 Bytes.

    -

    Encrypted S3 object storage​

    -

    Constellation comes with a service that you can use to transparently retrofit client-side encryption to existing applications that use S3 (AWS or compatible) for storage. -To learn more, check out the s3proxy documentation.

    Constellation images

    -

    Constellation uses a minimal version of Fedora as the operating system running inside confidential VMs. This Linux distribution is optimized for containers and designed to be stateless. -The Constellation images provide measured boot and an immutable filesystem.

    -

    Measured boot​

    - -

    Measured boot uses a Trusted Platform Module (TPM) to measure every part of the boot process. This allows for verification of the integrity of a running system at any point in time. To ensure correct measurements of every stage, each stage is responsible to measure the next stage before transitioning.

    -

    Firmware​

    -

    With confidential VMs, the firmware is the root of trust and is measured automatically at boot. After initialization, the firmware will load and measure the bootloader before executing it.

    -

    Bootloader​

    -

    The bootloader is the first modifiable part of the boot chain. The bootloader is tasked with loading the kernel, initramfs and setting the kernel command line. The Constellation bootloader measures these components before starting the kernel.

    -

    initramfs​

    -

    The initramfs is a small filesystem loaded to prepare the actual root filesystem. The Constellation initramfs maps the block device containing the root filesystem with dm-verity. The initramfs then mounts the root filesystem from the mapped block device.

    -

    dm-verity provides integrity checking using a cryptographic hash tree. When a block is read, its integrity is checked by verifying the tree against a trusted root hash. The initramfs reads this root hash from the previously measured kernel command line. Thus, if any block of the root filesystem's device is modified on disk, trying to read the modified block will result in a kernel panic at runtime.

    -

    After mounting the root filesystem, the initramfs will switch over and start the init process of the integrity-protected root filesystem.

    -

    State disk​

    -

    In addition to the read-only root filesystem, each Constellation node has a disk for storing state data. -This disk is mounted readable and writable by the initramfs and contains data that should persist across reboots. -Such data can contain sensitive information and, therefore, must be stored securely. -To that end, the state disk is protected by authenticated encryption. -See the section on keys and encryption for more information on the cryptographic primitives in use.

    Key management and cryptographic primitives

    -

    Constellation protects and isolates your cluster and workloads. -To that end, cryptography is the foundation that ensures the confidentiality and integrity of all components. -Evaluating the security and compliance of Constellation requires a precise understanding of the cryptographic primitives and keys used. -The following gives an overview of the architecture and explains the technical details.

    -

    Confidential VMs​

    -

    Confidential VM (CVM) technology comes with hardware and software components for memory encryption, isolation, and remote attestation. -For details on the implementations and cryptographic soundness, refer to the hardware vendors' documentation and advisories.

    -

    Master secret​

    -

    The master secret is the cryptographic material used for deriving the clusterID and the key encryption key (KEK) for storage encryption. -It's generated during the bootstrapping of a Constellation cluster. -It can either be managed by Constellation or an external key management system. -In case of recovery, the master secret allows to decrypt the state and recover a Constellation cluster.

    -

    Cluster identity​

    -

    The identity of a Constellation cluster is represented by cryptographic measurements:

    -

    The base measurements represent the identity of a valid, uninitialized Constellation node. -They depend on the node image, but are otherwise the same for every Constellation cluster. -On node boot, they're determined using the CVM's attestation mechanism and measured boot up to the read-only root filesystem.

    -

    The clusterID represents the identity of a single initialized Constellation cluster. -It's derived from the master secret and a cryptographically random salt and unique for every Constellation cluster. -The Bootstrapper measures the clusterID into its own PCR before executing any code not measured as part of the base measurements. -See Node attestation for details.

    -

    The remote attestation statement of a Constellation cluster combines the base measurements and the clusterID for a verifiable, unspoofable, unique identity.

    -

    Network encryption​

    -

    Constellation encrypts all cluster network communication using the container network interface (CNI). -See network encryption for more details.

    -

    The Cilium agent running on each node establishes a secure WireGuard tunnel between it and all other known nodes in the cluster. -Each node creates its own Curve25519 encryption key pair and distributes its public key via Kubernetes. -A node uses another node's public key to decrypt and encrypt traffic from and to Cilium-managed endpoints running on that node. -Connections are always encrypted peer-to-peer using ChaCha20 with Poly1305. -WireGuard implements forward secrecy with key rotation every 2 minutes.

    -

    Storage encryption​

    -

    Constellation supports transparent encryption of persistent storage. -The Linux kernel's device mapper-based encryption features are used to encrypt the data on the block storage level. -Currently, the following primitives are used for block storage encryption:

    - -

    Adding primitives for integrity protection in the CVM attacker model are under active development and will be available in a future version of Constellation. -See encrypted storage for more details.

    -

    As a cluster administrator, when creating a cluster, you can use the Constellation installation program to select one of the following methods for key management:

    -
      -
    • Constellation-managed key management
      • -
    • User-managed key management
      • -
    -

    Constellation-managed key management​

    -

    Key material and key derivation​

    -

    During the creation of a Constellation cluster, the cluster's master secret is used to derive a KEK. -This means creating two clusters with the same master secret will yield the same KEK. -Any data encryption key (DEK) is derived from the KEK via HKDF. -Note that the master secret is recommended to be unique for every cluster and shouldn't be reused (except in case of recovering a cluster).

    -

    State and storage​

    -

    The KEK is derived from the master secret during the initialization. -Subsequently, all other key material is derived from the KEK. -Given the same KEK, any DEK can be derived deterministically from a given identifier. -Hence, there is no need to store DEKs. They can be derived on demand. -After the KEK was derived, it's stored in memory only and never leaves the CVM context.

    -

    Availability​

    -

    Constellation-managed key management has the same availability as the underlying Kubernetes cluster. -Therefore, the KEK is stored in the distributed Kubernetes etcd storage to allow for unexpected but non-fatal (control-plane) node failure. -The etcd storage is backed by the encrypted and integrity protected state disk of the nodes.

    -

    Recovery​

    -

    Constellation clusters can be recovered in the event of a disaster, even when all node machines have been stopped and need to be rebooted. -For details on the process see the recovery workflow.

    -

    User-managed key management​

    -

    User-managed key management is under active development and will be available soon. -In scenarios where constellation-managed key management isn't an option, this mode allows you to keep full control of your keys. -For example, compliance requirements may force you to keep your KEKs in an on-prem key management system (KMS).

    -

    During the creation of a Constellation cluster, you specify a KEK present in a remote KMS. -This follows the common scheme of "bring your own key" (BYOK). -Constellation will support several KMSs for managing the storage and access of your KEK. -Initially, it will support the following KMSs:

    - -

    Storing the keys in Cloud KMS of AWS, Azure, or GCP binds the key usage to the particular cloud identity access management (IAM). -In the future, Constellation will support remote attestation-based access policies for Cloud KMS once available. -Note that using a Cloud KMS limits the isolation and protection to the guarantees of the particular offering.

    -

    KMIP support allows you to use your KMIP-compatible on-prem KMS and keep full control over your keys. -This follows the common scheme of "hold your own key" (HYOK).

    -

    The KEK is used to encrypt per-data "data encryption keys" (DEKs). -DEKs are generated to encrypt your data before storing it on persistent storage. -After being encrypted by the KEK, the DEKs are stored on dedicated cloud storage for persistence. -Currently, Constellation supports the following cloud storage options:

    - -

    The DEKs are only present in plaintext form in the encrypted main memory of the CVMs. -Similarly, the cryptographic operations for encrypting data before writing it to persistent storage are performed in the context of the CVMs.

    -

    Recovery and migration​

    -

    In the case of a disaster, the KEK can be used to decrypt the DEKs locally and subsequently use them to decrypt and retrieve the data. -In case of migration, configuring the same KEK will provide seamless migration of data. -Thus, only the DEK storage needs to be transferred to the new cluster alongside the encrypted data for seamless migration.

    Microservices

    -

    Constellation takes care of bootstrapping and initializing a Confidential Kubernetes cluster. -During the lifetime of the cluster, it handles day 2 operations such as key management, remote attestation, and updates. -These features are provided by several microservices:

    - -

    The relations between microservices are shown in the following diagram:

    - -

    Bootstrapper​

    -

    The Bootstrapper is the first microservice launched after booting a Constellation node image. -It sets up that machine as a Kubernetes node and integrates that node into the Kubernetes cluster. -To this end, the Bootstrapper first downloads and verifies the Kubernetes components at the configured versions. -The Bootstrapper tries to find an existing cluster and if successful, communicates with the JoinService to join the node. -Otherwise, it waits for an initialization request to create a new Kubernetes cluster.

    -

    JoinService​

    -

    The JoinService runs as DaemonSet on each control-plane node. -New nodes (at cluster start, or later through autoscaling) send a request to the service over attested TLS (aTLS). -The JoinService verifies the new node's certificate and attestation statement. -If attestation is successful, the new node is supplied with an encryption key from the KeyService for its state disk, and a Kubernetes bootstrap token.

    - -

    VerificationService​

    -

    The VerificationService runs as DaemonSet on each node. -It provides user-facing functionality for remote attestation during the cluster's lifetime via an endpoint for verifying the cluster. -Read more about the hardware-based attestation feature of Constellation and how to verify a cluster on the client side.

    -

    KeyService​

    -

    The KeyService runs as DaemonSet on each control-plane node. -It implements the key management for the storage encryption keys in Constellation. These keys are used for the state disk of each node and the transparently encrypted storage for Kubernetes. -Depending on wether the constellation-managed or user-managed mode is used, the KeyService holds the key encryption key (KEK) directly or calls an external key management service (KMS) for key derivation respectively.

    Network encryption

    -

    Constellation encrypts all pod communication using the container network interface (CNI). -To that end, Constellation deploys, configures, and operates the Cilium CNI plugin. -Cilium provides transparent encryption for all cluster traffic using either IPSec or WireGuard. -Currently, Constellation only supports WireGuard as the encryption engine. -You can read more about the cryptographic soundness of WireGuard in their white paper.

    -

    Cilium is actively working on implementing a feature called host-to-host encryption mode for WireGuard. -With host-to-host, all traffic between nodes will be tunneled via WireGuard (host-to-host, host-to-pod, pod-to-host, pod-to-pod). -Until the host-to-host feature is released, Constellation enables pod-to-pod encryption. -This mode encrypts all traffic between Kubernetes pods using WireGuard tunnels.

    -

    When using Cilium in the default setup but with encryption enabled, there is a known issue -that can cause pod-to-pod traffic to be unencrypted. -To mitigate this issue, Constellation adds a strict mode to Cilium's pod-to-pod encryption. -This mode changes the default behavior of traffic that's destined for an unknown endpoint to not be send out in plaintext, but instead being dropped. -The strict mode distinguishes between traffic that's send to a pod from traffic that's destined for a cluster-external endpoint by considering the pod's CIDR range.

    -

    Traffic originating from hosts isn't encrypted yet. -This mainly includes health checks from Kubernetes API server. -Also, traffic proxied over the API server via e.g. kubectl port-forward isn't encrypted.

    Observability

    -

    In Kubernetes, observability is the ability to gain insight into the behavior and performance of applications. -It helps identify and resolve issues more effectively, ensuring stability and performance of Kubernetes workloads, reducing downtime and outages, and improving efficiency. -The "three pillars of observability" are logs, metrics, and traces.

    -

    In the context of Confidential Computing, observability is a delicate subject and needs to be applied such that it doesn't leak any sensitive information. -The following gives an overview of where and how you can apply standard observability tools in Constellation.

    -

    Cloud resource monitoring​

    -

    While inaccessible, Constellation's nodes are still visible as black box VMs to the hypervisor. -Resource consumption, such as memory and CPU utilization, can be monitored from the outside and observed via the cloud platforms directly. -Similarly, other resources, such as storage and network and their respective metrics, are visible via the cloud platform.

    -

    Metrics​

    -

    Metrics are numeric representations of data measured over intervals of time. They're essential for understanding system health and gaining insights using telemetry signals.

    -

    By default, Constellation exposes the metrics for Kubernetes system components inside the cluster. -Similarly, the etcd metrics endpoints are exposed inside the cluster. -These metrics endpoints can be disabled.

    -

    You can collect these cluster-internal metrics via tools such as Prometheus or the Elastic Stack.

    -

    Constellation's CNI Cilium also supports metrics via Prometheus endpoints. -However, in Constellation, they're disabled by default and must be enabled first.

    -

    Logs​

    -

    Logs represent discrete events that usually describe what's happening with your service. -The payload is an actual message emitted from your system along with a metadata section containing a timestamp, labels, and tracking identifiers.

    -

    System logs​

    -

    Detailed system-level logs are accessible via /var/log and journald on the nodes directly. -They can be collected from there, for example, via Filebeat and Logstash, which are tools of the Elastic Stack.

    -

    In case of an error during the initialization, the CLI automatically collects the Bootstrapper logs and returns these as a file for troubleshooting. Here is an example of such an event:

    -
    Cluster initialization failed. This error is not recoverable.
    Terminate your cluster and try again.
    Fetched bootstrapper logs are stored in "constellation-cluster.log"
    -

    Kubernetes logs​

    -

    Constellation supports the Kubernetes logging architecture. -By default, logs are written to the nodes' encrypted state disks. -These include the Pod and container logs and the system component logs.

    -

    Constellation services run as Pods inside the kube-system namespace and use the standard container logging mechanism. -The same applies for the Cilium Pods.

    -

    You can collect logs from within the cluster via tools such as Fluentd, Loki, or the Elastic Stack.

    -

    Traces​

    -

    Modern systems are implemented as interconnected complex and distributed microservices. Understanding request flows and system communications is challenging, mainly because all systems in a chain need to be modified to propagate tracing information. Distributed tracing is a new approach to increasing observability and understanding performance bottlenecks. A trace represents consecutive events that reflect an end-to-end request path in a distributed system.

    -

    Constellation supports traces for Kubernetes system components. -By default, they're disabled and need to be enabled first.

    -

    Similarly, Cilium can be enabled to export traces.

    -

    You can collect these traces via tools such as Jaeger or Zipkin.

    -

    Integrations​

    -

    Platforms and SaaS solutions such as Datadog, logz.io, Dynatrace, or New Relic facilitate the observability challenge for Kubernetes and provide all-in-one SaaS solutions. -They install agents into the cluster that collect metrics, logs, and tracing information and upload them into the data lake of the platform. -Technically, the agent-based approach is compatible with Constellation, and attaching these platforms is straightforward. -However, you need to evaluate if the exported data might violate Constellation's compliance and privacy guarantees by uploading them to a third-party platform.

    Orchestrating Constellation clusters

    -

    You can use the CLI to create a cluster on the supported cloud platforms. -The CLI provisions the resources in your cloud environment and initiates the initialization of your cluster. -It uses a set of parameters and an optional configuration file to manage your cluster installation. -The CLI is also used for updating your cluster.

    -

    Workspaces​

    -

    Each Constellation cluster has an associated workspace. -The workspace is where data such as the Constellation state and config files are stored. -Each workspace is associated with a single cluster and configuration. -The CLI stores state in the local filesystem making the current directory the active workspace. -Multiple clusters require multiple workspaces, hence, multiple directories. -Note that every operation on a cluster always has to be performed from the directory associated with its workspace.

    -

    You may copy files from the workspace to other locations, -but you shouldn't move or delete them while the cluster is still being used. -The Constellation CLI takes care of managing the workspace. -Only when a cluster was terminated, and you are sure the files aren't needed anymore, should you remove a workspace.

    -

    Cluster creation process​

    -

    To allow for fine-grained configuration of your cluster and cloud environment, Constellation supports an extensive configuration file with strong defaults. Generating the configuration file is typically the first thing you do in the workspace.

    -

    Altogether, the following files are generated during the creation of a Constellation cluster and stored in the current workspace:

    -
      -
    • a configuration file
      • -
    • a state file
      • -
    • a Base64-encoded master secret
      • -
    • Terraform artifacts, stored in subdirectories
      • -
    • a Kubernetes kubeconfig file.
      • -
    -

    After the initialization of your cluster, the CLI will provide you with a Kubernetes kubeconfig file. -This file grants you access to your Kubernetes cluster and configures the kubectl tool. -In addition, the cluster's identifier is returned and stored in the state file.

    -

    Creation process details​

    -
      -
    1. The CLI apply command first creates the confidential VM (CVM) resources in your cloud environment and configures the network
      2. -
    2. Each CVM boots the Constellation node image and measures every component in the boot chain
      3. -
    3. The first microservice launched in each node is the Bootstrapper
      4. -
    4. The Bootstrapper waits until it either receives an initialization request or discovers an initialized cluster
      5. -
    5. The CLI then connects to the Bootstrapper of a selected node, sends the configuration, and initiates the initialization of the cluster
      6. -
    6. The Bootstrapper of that node initializes the Kubernetes cluster and deploys the other Constellation microservices including the JoinService
      7. -
    7. Subsequently, the Bootstrappers of the other nodes discover the initialized cluster and send join requests to the JoinService
      8. -
    8. As part of the join request each node includes an attestation statement of its boot measurements as authentication
      9. -
    9. The JoinService verifies the attestation statements and joins the nodes to the Kubernetes cluster
      10. -
    10. This process is repeated for every node joining the cluster later (e.g., through autoscaling)
      11. -
    -

    Post-installation configuration​

    -

    Post-installation the CLI provides a configuration for accessing the cluster using the Kubernetes API. -The kubeconfig file provides the credentials and configuration for connecting and authenticating to the API server. -Once configured, orchestrate the Kubernetes cluster via kubectl.

    -

    After the initialization, the CLI will present you with a couple of tokens:

    -
      -
    • The master secret (stored in the constellation-mastersecret.json file by default)
      • -
    • The clusterID of your cluster in Base64 encoding
      • -
    -

    You can read more about these values and their meaning in the guide on cluster identity.

    -

    The master secret must be kept secret and can be used to recover your cluster. -Instead of managing this secret manually, you can use your key management solution of choice with Constellation.

    -

    The clusterID uniquely identifies a cluster and can be used to verify your cluster.

    -

    Upgrades​

    -

    Constellation images and microservices may need to be upgraded to new versions during the lifetime of a cluster. -Constellation implements a rolling update mechanism ensuring no downtime of the control or data plane. -You can upgrade a Constellation cluster with a single operation by using the CLI. -For step-by-step instructions on how to do this, refer to Upgrade your cluster.

    -

    Attestation of upgrades​

    -

    With every new image, corresponding measurements are released. -During an update procedure, the CLI provides new measurements to the JoinService securely. -New measurements for an updated image are automatically pulled and verified by the CLI following the supply chain security concept of Constellation. -The attestation section describes in detail how these measurements are then used by the JoinService for the attestation of nodes.

    📄️ Security benefits

    Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

    Deploying Filestash

    -

    Filestash is a web frontend for different storage backends, including S3. -It's a useful application to showcase s3proxy in action.

    -
      -
    1. Deploy s3proxy as described in Deployment.
      2. -
    2. Create a deployment file for Filestash with one pod:
      3. -
    -

    The pod spec includes the hostAliases key, which adds an entry to the pod's /etc/hosts. -The entry forwards all requests for any of the currently defined AWS regions to the Kubernetes service s3proxy-service. -If you followed the s3proxy Deployment guide, this service points to a s3proxy pod.

    -

    The deployment specifies all regions explicitly to prevent accidental data leaks. -If one of your buckets were located in a region that's not part of the hostAliases key, traffic towards those buckets would not be redirected to s3proxy. -Similarly, if you want to exclude data for specific regions from going through s3proxy you can remove those regions from the deployment.

    -

    The spec also includes a volume mount for the TLS certificate and adds it to the pod's certificate trust store. -The volume is called ca-cert. -The key ca.crt of that volume is mounted to /etc/ssl/certs/kube-ca.crt, which is the default certificate trust store location for that container's OpenSSL library. -Not adding the CA certificate will result in TLS authentication errors.

    -
      -
    1. Apply the file: kubectl apply -f deployment-filestash.yaml
      2. -
    -

    Afterward, you can use a port forward to access the Filestash pod: -kubectl port-forward pod/$(kubectl get pod --selector='app=filestash' -o=jsonpath='{.items[*].metadata.name}') 8334:8334

    -
      -
    1. -

      After browsing to localhost:8443, Filestash will ask you to set an administrator password. -After setting it, you can directly leave the admin area by clicking the blue cloud symbol in the top left corner. -Subsequently, you can select S3 as storage backend and enter your credentials. -This will bring you to an overview of your buckets. -If you want to deploy Filestash in production, take a look at its documentation.

      -
      2. -
    2. -

      To see the logs of s3proxy intercepting requests made to S3, run: kubectl logs -f pod/$(kubectl get pod --selector='app=s3proxy' -o=jsonpath='{.items[*].metadata.name}') -Look out for log messages labeled intercepting. -There is one such log message for each message that's encrypted, decrypted, or blocked.

      -
      3. -
    3. -

      Once you have uploaded a file with Filestash, you should be able to view the file in Filestash. -However, if you go to the AWS S3 Web UI and download the file you just uploaded in Filestash, you won't be able to read it. -Another way to spot encrypted files without downloading them is to click on a file, scroll to the Metadata section, and look for the header named x-amz-meta-constellation-encryption. -This header holds the encrypted data encryption key of the object and is only present on objects that are encrypted by s3proxy.

    Horizontal Pod Autoscaling

    -

    This example demonstrates Constellation's autoscaling capabilities. It's based on the Kubernetes HorizontalPodAutoscaler Walkthrough. During the following steps, Constellation will spawn new VMs on demand, verify them, add them to the cluster, and delete them again when the load has settled down.

    -

    Requirements​

    -

    The cluster needs to be initialized with Kubernetes 1.23 or later. In addition, autoscaling must be enabled to enable Constellation to assign new nodes dynamically.

    -

    Just for this example specifically, the cluster should have as few worker nodes in the beginning as possible. Start with a small cluster with only one low-powered node for the control-plane node and one low-powered worker node.

    -
    info

    We tested the example using instances of types Standard_DC4as_v5 on Azure and n2d-standard-4 on GCP.

    -

    Setup​

    -
      -
    1. -

      Install the Kubernetes Metrics Server:

      -
      kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
      -
      2. -
    2. -

      Deploy the HPA example server that's supposed to be scaled under load.

      -

      This manifest is similar to the one from the Kubernetes HPA walkthrough, but with increased CPU limits and requests to facilitate the triggering of node scaling events.

      Create a HorizontalPodAutoscaler.

      -

      Set an average CPU usage across all Pods of 20% to see one additional worker node being created later. Note that the CPU usage isn't related to the host CPU usage, but rather to the requested CPU capacities (20% of 600 milli-cores CPU across all Pods). See the original tutorial for more information on the HPA configuration.

      -
      kubectl autoscale deployment php-apache --cpu-percent=20 --min=1 --max=10
      -
      4. -
    4. -

      Create a Pod that generates load on the server:

      -
      kubectl run -i --tty load-generator --rm --image=busybox:1.28 --restart=Never -- /bin/sh -c "while true; do wget -q -O- http://php-apache; done"
      -
      5. -
    5. -

      Wait a few minutes until new nodes are added to the cluster. You can monitor the state of the HorizontalPodAutoscaler, the list of nodes, and the behavior of the autoscaler.

      -
      6. -
    6. -

      To stop the load generator, press CTRL+C and run:

      -
      kubectl delete pod load-generator
      -
      7. -
    7. -

      The cluster-autoscaler checks every few minutes if nodes are underutilized. It will taint such candidates for removal and wait additional 10 minutes before the nodes are eventually removed and deallocated. The whole process can take about 20 minutes.

      -
      8. -
    -

    Monitoring​

    -
    tip

    For better observability, run the listed commands in different tabs in your terminal.

    -

    You can watch the status of the HorizontalPodAutoscaler with the current CPU usage, the target CPU limit, and the number of replicas created with:

    -
    kubectl get hpa php-apache --watch
    -

    From time to time compare the list of nodes to check the behavior of the autoscaler:

    -
    kubectl get nodes
    -

    For deeper insights, see the logs of the autoscaler Pod, which contains more details about the scaling decision process:

    -
    kubectl logs -f deployment/constellation-cluster-autoscaler -n kube-system

    First steps with a local cluster

    -

    A local cluster lets you deploy and test Constellation without a cloud subscription. -You have two options:

    -
      -
    • Use MiniConstellation to automatically deploy a two-node cluster.
      • -
    • For more fine-grained control, create the cluster using the QEMU provider.
      • -
    -

    Both options use virtualization to create a local cluster with control-plane nodes and worker nodes. They don't require hardware with Confidential VM (CVM) support. For attestation, they currently use a software-based vTPM provided by KVM/QEMU.

    -

    You need an x64 machine with a Linux OS. -You can use a VM, but it needs nested virtualization.

    -

    Prerequisites​

    -
      -
    • Machine requirements: -
        -
      • An x86-64 CPU with at least 4 cores (6 cores are recommended)
        • -
      • At least 4 GB RAM (6 GB are recommended)
        • -
      • 20 GB of free disk space
        • -
      • Hardware virtualization enabled in the BIOS/UEFI (often referred to as Intel VT-x or AMD-V/SVM) / nested-virtualization support when using a VM
        • -
      -
      • -
    • Software requirements: - -
      • -
    -

    Software installation on Ubuntu​

    -
    # install Docker
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
    echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
    sudo apt update
    sudo apt install docker-ce
    # install other dependencies
    sudo apt install xsltproc
    sudo snap install kubectl --classic
    # install Constellation CLI
    curl -LO https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64
    sudo install constellation-linux-amd64 /usr/local/bin/constellation
    # do not drop forwarded packages
    sudo iptables -P FORWARD ACCEPT
    -

    Create a cluster​

    -

    With the constellation mini command, you can deploy and test Constellation locally. This mode is called MiniConstellation. Conceptually, MiniConstellation is similar to MicroK8s, K3s, and minikube.

    caution

    MiniConstellation has specific soft- and hardware requirements such as a Linux OS running on an x86-64 CPU. Pay attention to all prerequisites when setting up.

    note

    Since MiniConstellation runs on your local system, cloud features such as load balancing, -attaching persistent storage, or autoscaling aren't available.

    The following creates your MiniConstellation cluster (may take up to 10 minutes to complete):

    constellation mini up

    This will configure your current directory as the workspace for this cluster. -All constellation commands concerning this cluster need to be issued from this directory.

    -

    Connect to the cluster​

    -

    Your cluster initially consists of a single control-plane node:

    -
    $ kubectl get nodes
    NAME              STATUS   ROLES           AGE   VERSION
    control-plane-0   Ready    control-plane   66s   v1.24.6
    -

    Additional nodes will request to join the cluster shortly. Before each additional node is allowed to join the cluster, its state is verified using remote attestation by the JoinService. -If verification passes successfully, the new node receives keys and certificates to join the cluster.

    -

    You can follow this process by viewing the logs of the JoinService:

    -
    $ kubectl logs -n kube-system daemonsets/join-service -f
    {"level":"INFO","ts":"2022-10-14T09:32:20Z","caller":"cmd/main.go:48","msg":"Constellation Node Join Service","version":"2.1.0","cloudProvider":"qemu"}
    {"level":"INFO","ts":"2022-10-14T09:32:20Z","logger":"validator","caller":"watcher/validator.go:96","msg":"Updating expected measurements"}
    ...
    -

    Once all nodes have joined your cluster, it may take a couple of minutes for all resources to become available. -You can check on the state of your cluster by running the following:

    -
    $ kubectl get nodes
    NAME              STATUS   ROLES           AGE     VERSION
    control-plane-0   Ready    control-plane   2m59s   v1.24.6
    worker-0          Ready    <none>          32s     v1.24.6
    -

    Deploy a sample application​

    -
      -
    1. Deploy the emojivoto app
      2. -
    -
    kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
    -
      -
    1. Expose the frontend service locally
      2. -
    -
    kubectl wait --for=condition=available --timeout=60s -n emojivoto --all deployments
    kubectl -n emojivoto port-forward svc/web-svc 8080:80 &
    curl http://localhost:8080
    kill %1
    -

    Terminate your cluster​

    -

    Once you are done, you can clean up the created resources using the following command:

    constellation mini down

    This will destroy your cluster and clean up your workspace. -The VM image and cluster configuration file (constellation-conf.yaml) will be kept and may be reused to create new clusters.

    -

    Troubleshooting​

    -

    Make sure to use the latest release and check out the known issues.

    -

    VMs have no internet access / CLI remains in "Initializing cluster" state​

    -

    iptables rules may prevent your VMs from accessing the internet. -Make sure your rules aren't dropping forwarded packages.

    -

    List your rules:

    -
    sudo iptables -S
    -

    The output may look similar to the following:

    -
    -P INPUT ACCEPT
    -P FORWARD DROP

    First steps with Constellation

    -

    The following steps guide you through the process of creating a cluster and deploying a sample app. This example assumes that you have successfully installed and set up Constellation, -and have access to a cloud subscription.

    -
    tip

    If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

    -
    note

    If you encounter any problem with the following steps, make sure to use the latest release and check out the known issues.

    -

    Create a cluster​

    -
      -
    1. -

      Create the configuration file and state file for your cloud provider. If you are following the steps of this guide, there is no need to edit the file.

      -
      constellation config generate aws
      -
      2. -
    2. -

      Create your IAM configuration.

      -
      constellation iam create aws --zone=us-east-2a --prefix=constellTest --update-config

      This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created. It also updates the configuration file constellation-conf.yaml in your current directory with the IAM values filled in.

      Depending on the attestation variant selected on config generation, different regions are available. -AMD SEV-SNP machines (requires the default attestation variant awsSEVSNP) are currently available in the following regions:

        -
      • eu-west-1
        • -
      • us-east-2
        • -

      You can find a list of regions that support AMD SEV-SNP in AWS's documentation.

      NitroTPM machines (requires the attestation variant awsNitroTPM) are available in all regions. -Constellation OS images are currently replicated to the following regions:

        -
      • eu-central-1
        • -
      • eu-west-1
        • -
      • eu-west-3
        • -
      • us-east-2
        • -
      • ap-south-1

    -

    Use the CLI to terminate your cluster. If you manually used Terraform to manage your cloud resources, follow the corresponding instructions in the Terminate workflow.

    -
    constellation terminate
    -

    This should give the following output:

    -
    $ constellation terminate
    You are about to terminate a Constellation cluster.
    All of its associated resources will be DESTROYED.
    This action is irreversible and ALL DATA WILL BE LOST.
    Do you want to continue? [y/n]:

    Installation and setup

    -

    Constellation runs entirely in your cloud environment and can be controlled via a dedicated command-line interface (CLI) or a Terraform provider.

    -

    Prerequisites​

    -

    Make sure the following requirements are met:

    -
      -
    • Your machine is running Linux, macOS, or Windows
      • -
    • You have admin rights on your machine
      • -
    • kubectl is installed
      • -
    • Your CSP is Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), or STACKIT
      • -
    -

    Install the Constellation CLI​

    -
    tip

    If you prefer to use Terraform, you can alternatively use the Terraform provider to manage the cluster's lifecycle.

    -

    The CLI executable is available at GitHub. -Install it with the following commands:

    -
      -
    1. Download the CLI:
      2. -
    curl -LO https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64
      -
    1. -

      Verify the signature (optional)

      -
      2. -
    2. -

      Install the CLI to your PATH:

      -
      3. -
    sudo install constellation-linux-amd64 /usr/local/bin/constellation
    -
    tip

    The CLI supports autocompletion for various shells. To set it up, run constellation completion and follow the given steps.

    -

    Set up cloud credentials​

    -

    Constellation makes authenticated calls to the CSP API. Therefore, you need to set up Constellation with the credentials for your CSP.

    -
    tip

    If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

    -

    Required permissions​

    -

    To set up a Constellation cluster, you need to perform two tasks that require permissions: create the infrastructure and create roles for cluster nodes. Both of these actions can be performed by different users, e.g., an administrator to create roles and a DevOps engineer to create the infrastructure.

    To create the IAM configuration for Constellation, you need the following permissions:

    {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "ec2:DescribeAccountAttributes",
                    "iam:AddRoleToInstanceProfile",
                    "iam:AttachRolePolicy",
                    "iam:CreateInstanceProfile",

                    "iam:DetachRolePolicy",
                    "iam:GetInstanceProfile",
                    "iam:GetPolicy",
                    "iam:GetPolicyVersion",
                    "iam:GetRole",
                    "iam:ListAttachedRolePolicies",
                    "iam:ListInstanceProfilesForRole",
                    "iam:ListPolicyVersions",
                    "iam:ListRolePolicies",
                    "iam:PassRole",
                    "iam:RemoveRoleFromInstanceProfile",
                    "sts:GetCallerIdentity"
                ],
                "Resource": "*"
            }
        ]
    }

    The built-in AdministratorAccess policy is a superset of these permissions.

    To create a Constellation cluster, see the permissions of main.tf.

    The built-in PowerUserAccess policy is a superset of these permissions.

    Follow Amazon's guide on understanding and managing policies.

    -

    Authentication​

    -

    You need to authenticate with your CSP. The following lists the required steps for testing and production environments.

    -
    note

    The steps for a testing environment are simpler. However, they may expose secrets to the CSP. If in doubt, follow the production steps.

    -

    Testing

    You can use the AWS CloudShell. Make sure you are authorized to use it.

    Production

    Use the latest version of the AWS CLI on a trusted machine:

    aws configure

    Options and first steps are described in the AWS CLI documentation.

    -

    Next steps​

    -

    Using Constellation via Cloud Marketplaces

    -

    Constellation is available through the Marketplaces of AWS, Azure, GCP, and STACKIT. This allows you to create self-managed Constellation clusters that are billed on a pay-per-use basis (hourly, per vCPU) with your CSP account. You can still get direct support by Edgeless Systems. For more information, please contact us.

    -

    This document explains how to run Constellation with the dynamically billed cloud marketplace images.

    -

    To use Constellation's marketplace images, ensure that you are subscribed to the marketplace offering through the web portal.

    Then, enable the use of marketplace images in your Constellation constellation-conf.yaml config file:

    yq eval -i ".provider.aws.useMarketplaceImage = true" constellation-conf.yaml
    -

    Ensure that the cluster uses an official release image version (i.e., .image=vX.Y.Z in the constellation-conf.yaml file).

    -

    From there, you can proceed with the cluster creation as usual.

    -
    Maintenance Notice

    Constellation is no longer actively maintained by Edgeless Systems.

    This project is no longer receiving updates or support from Edgeless Systems. The repository and documentation remain available for archival purposes and community use.

    -

    Welcome to the documentation of Constellation! Constellation is a Kubernetes engine that aims to provide the best possible data security.

    -

    Constellation concept

    -

    Constellation shields your entire Kubernetes cluster from the underlying cloud infrastructure. Everything inside is always encrypted, including at runtime in memory. For this, Constellation leverages a technology called confidential computing and more specifically Confidential VMs.

    -
    tip

    See the 📄whitepaper for more information on confidential computing.

    -

    Goals​

    -

    From a security perspective, Constellation is designed to keep all data always encrypted and to prevent any access from the underlying (cloud) infrastructure. This includes access from datacenter employees, privileged cloud admins, and attackers coming through the infrastructure. Such attackers could be malicious co-tenants escalating their privileges or hackers who managed to compromise a cloud server.

    -

    From a DevOps perspective, Constellation is designed to work just like what you would expect from a modern Kubernetes engine.

    -

    Use cases​

    -

    Constellation provides unique security features and benefits. The core use cases are:

    -
      -
    • Increasing the overall security of your clusters
      • -
    • Increasing the trustworthiness of your SaaS offerings
      • -
    • Moving sensitive workloads from on-prem to the cloud
      • -
    • Meeting regulatory requirements
      • -
    -

    Next steps​

    Feature status of clouds

    -

    What works on which cloud? Currently, Confidential VMs (CVMs) are available in varying quality on the different clouds and software stacks.

    -

    For Constellation, the ideal environment provides the following:

    -
      -
    1. Ability to run arbitrary software and images inside CVMs
      2. -
    2. CVMs based on AMD SEV-SNP (available in EPYC CPUs since the Milan generation) or Intel TDX (available in Xeon CPUs since the Sapphire Rapids generation)
      3. -
    3. Ability for CVM guests to obtain raw hardware attestation statements
      4. -
    4. Reviewable, open-source firmware inside CVMs
      5. -
    5. Capability of the firmware to attest the integrity of the code it passes control to, e.g., with an embedded virtual TPM (vTPM)
      6. -
    -

    (1) is a functional must-have. (2)--(5) are required for remote attestation that fully keeps the infrastructure/cloud out. Constellation can work without them or with approximations, but won't protect against certain privileged attackers anymore.

    Amazon Web Services (AWS)​

    -

    Amazon EC2 supports AMD SEV-SNP. -Regarding (3), AWS provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the NitroTPM for measured boot, which is a vTPM managed by the Nitro hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the firmware is open source and can be reproducibly built.

    -

    Microsoft Azure​

    -

    With its CVM offering, Azure provides the best foundations for Constellation. -Regarding (3), Azure provides direct access to attestation statements. -The firmware runs in an isolated domain inside the CVM and exposes a vTPM (5), but it's closed source (4). -On SEV-SNP, Azure uses VM Privilege Level (VMPL) isolation for the separation of firmware and the rest of the VM; on TDX, they use TD partitioning. -This firmware is signed by Azure. -The signature is reflected in the attestation statements of CVMs. -Thus, the Azure closed-source firmware becomes part of Constellation's trusted computing base (TCB).

    -

    * Recently, Azure announced the open source paravisor OpenHCL. It's the foundation for fully open source and verifiable CVM firmware. Once Azure provides their CVM firmware with reproducible builds based on OpenHCL, (4) switches from No to Yes. Constellation will support OpenHCL based firmware on Azure in the future.

    -

    Google Cloud Platform (GCP)​

    -

    The CVMs Generally Available in GCP are based on AMD SEV-ES or SEV-SNP. -Regarding (3), with their SEV-SNP offering Google provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the Shielded VM vTPM for measured boot, which is a vTPM managed by Google's hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the CVMs still include closed-source firmware.

    -

    TDX on Google is in public preview. -With it, Constellation would have a similar TCB and attestation flow as with the current SEV-SNP offering.

    -

    STACKIT​

    -

    STACKIT Compute Engine supports AMD SEV-ES. A vTPM is used for measured boot, which is a vTPM managed by STACKIT's hypervisor. Hence, the hypervisor is currently part of Constellation's TCB.

    -

    OpenStack​

    -

    OpenStack is an open-source cloud and infrastructure management software. It's used by many smaller CSPs and datacenters. In the latest Yoga version, OpenStack has basic support for CVMs. However, much depends on the employed kernel and hypervisor. Features (2)--(4) are likely to be a Yes with Linux kernel version 6.2. Thus, going forward, OpenStack on corresponding AMD or Intel hardware will be a viable underpinning for Constellation.

    -

    Conclusion​

    -

    The different clouds and software like the Linux kernel and OpenStack are in the process of building out their support for state-of-the-art CVMs. Azure has already most features in place. For Constellation, the status quo means that the TCB has different shapes on different infrastructures. With broad SEV-SNP support coming to the Linux kernel, we soon expect a normalization of features across infrastructures.

    Confidential Kubernetes

    -

    We use the term Confidential Kubernetes to refer to the concept of using confidential-computing technology to shield entire Kubernetes clusters from the infrastructure. The three defining properties of this concept are:

    -
      -
    1. Workload shielding: the confidentiality and integrity of all workload-related data and code are enforced.
      2. -
    2. Control plane shielding: the confidentiality and integrity of the cluster's control plane, state, and workload configuration are enforced.
      3. -
    3. Attestation and verifiability: the two properties above can be verified remotely based on hardware-rooted cryptographic certificates.
      4. -
    -

    Each of the above properties is equally important. Only with all three in conjunction, an entire cluster can be shielded without gaps.

    -

    Constellation security features​

    -

    Constellation implements the Confidential Kubernetes concept with the following security features.

    -
      -
    • Runtime encryption: Constellation runs all Kubernetes nodes inside Confidential VMs (CVMs). This gives runtime encryption for the entire cluster.
      • -
    • Network and storage encryption: Constellation augments this with transparent encryption of the network, persistent storage, and other managed storage like AWS S3. Thus, workloads and control plane are truly end-to-end encrypted: at rest, in transit, and at runtime.
      • -
    • Transparent key management: Constellation manages the corresponding cryptographic keys inside CVMs.
      • -
    • Node attestation and verification: Constellation verifies the integrity of each new CVM-based node using remote attestation. Only "good" nodes receive the cryptographic keys required to access the network and storage of a cluster.
      • -
    • Confidential computing-optimized images: A node is "good" if it's running a signed Constellation node image inside a CVM and is in the expected state. (Node images are hardware-measured during boot. The measurements are reflected in the attestation statements that are produced by nodes and verified by Constellation.)
      • -
    • "Whole cluster" attestation: Towards the DevOps engineer, Constellation provides a single hardware-rooted certificate from which all of the above can be verified.
      • -
    -

    With the above, Constellation wraps an entire cluster into one coherent and verifiable confidential context. The concept is depicted in the following.

    -

    Confidential Kubernetes

    -

    Comparison: Managed Kubernetes with CVMs​

    -

    In comparison, managed Kubernetes with CVMs, as it's for example offered in AKS and GKE, only provides runtime encryption for certain worker nodes. Here, each worker node is a separate (and typically unverified) confidential context. This only provides limited security benefits as it only prevents direct access to a worker node's memory. The large majority of potential attacks through the infrastructure remain unaffected. This includes attacks through the control plane, access to external key management, and the corruption of worker node images. This leaves many problems unsolved. For instance, Node A has no means to verify if Node B is "good" and if it's OK to share data with it. Consequently, this approach leaves a large attack surface, as is depicted in the following.

    HashiCorp Vault​

    -

    HashiCorp Vault is a distributed secrets management software that can be deployed to Kubernetes. -HashiCorp maintains a benchmarking tool for vault, vault-benchmark. -Vault-benchmark generates load on a Vault deployment and measures response times.

    -

    This article describes the results from running vault-benchmark on Constellation, AKS, and GKE. -You can find the setup for producing the data discussed in this article in the vault-benchmarks repository.

    -

    The Vault API used during benchmarking is the transits secret engine. -This allows services to send data to Vault for encryption, decryption, signing, and verification.

    -

    Results​

    -

    On each run, vault-benchmark sends requests and measures the latencies. -The measured latencies are aggregated through various statistical features. -After running the benchmark n times, the arithmetic mean over a subset of the reported statistics is calculated. -The selected features are arithmetic mean, 99th percentile, minimum, and maximum.

    -

    Arithmetic mean gives a general sense of the latency on each target. -The 99th percentile shows performance in (most likely) erroneous states. -Minimum and maximum mark the range within which latency varies each run.

    -

    The benchmark was configured with 1300 workers and 10 seconds per run. -Those numbers were chosen empirically. -The latency was stabilizing at 10 seconds runtime, not changing with further increase. -Increasing the number of workers beyond 1300 leads to request failures, marking the limit Vault was able to handle in this setup. -All results are based on 100 runs.

    -

    The following data was generated while running five replicas, one primary, and four standby nodes. -All numbers are in seconds if not indicated otherwise.

    Min:    +25.710886 % (GKE is faster)
    -

    Interpretation: Latencies are all within ~5% of each other. -AKS performs slightly better than GKE and Constellation (C11n) in all cases except minimum latency. -Minimum latency is the lowest for GKE. -Compared to GKE, Constellation had slightly lower peak latencies (99th percentile and maximum), indicating that Constellation could have handled slightly more concurrent accesses than GKE. -Overall, performance is at comparable levels across all three distributions. -Based on these numbers, you can use a similarly sized Constellation cluster to run your existing Vault deployment.

    Impact of runtime encryption on compute performance

    -

    All nodes in a Constellation cluster are executed inside Confidential VMs (CVMs). Consequently, the performance of Constellation is inherently linked to the performance of these CVMs.

    -

    AMD and Azure benchmarking​

    -

    AMD and Azure have collectively released a performance benchmark for CVMs that utilize 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. This benchmark, which included a variety of mostly compute-intensive tests such as SPEC CPU 2017 and CoreMark, demonstrated that CVMs experience only minor performance degradation (ranging from 2% to 8%) when compared to standard VMs. Such results are indicative of the performance that can be expected from compute-intensive workloads running with Constellation on Azure.

    -

    AMD and Google benchmarking​

    -

    Similarly, AMD and Google have jointly released a performance benchmark for CVMs employing 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. With high-performance computing workloads such as WRF, NAMD, Ansys CFS, and Ansys LS_DYNA, they observed analogous findings, with only minor performance degradation (between 2% and 4%) compared to standard VMs. These outcomes are reflective of the performance that can be expected for compute-intensive workloads running with Constellation on GCP.

    Runtime encryption affects compute performance. Benchmarks by Azure and Google show that the performance degradation of Confidential VMs (CVMs) is small, ranging from 2% to 8% for compute-intensive workloads.

    -

    I/O performance benchmarks​

    -

    We evaluated the I/O performance of Constellation, utilizing a collection of synthetic benchmarks targeting networking and storage. -We further compared this performance to native managed Kubernetes offerings from various cloud providers, to better understand how Constellation stands in relation to standard practices.

    -

    Application benchmarking​

    -

    To gauge Constellation's applicability to well-known applications, we performed a benchmark of HashiCorp Vault running on Constellation. -The results were then compared to deployments on the managed Kubernetes offerings from different cloud providers, providing a tangible perspective on Constellation's performance in actual deployment scenarios.

    Results​

    -

    Network​

    -

    This section gives a thorough analysis of the network performance of Constellation, specifically focusing on measuring TCP and UDP bandwidth. -The benchmark measured the bandwidth of pod-to-pod and pod-to-service connections between two different nodes using iperf.

    -

    GKE and Constellation on GCP had a maximum network bandwidth of 10 Gbps. -AKS with Standard_D4as_v5 machines a maximum network bandwidth of 12.5 Gbps. -The Confidential VM equivalent Standard_DC4as_v5 currently has a network bandwidth of 1.25 Gbps. -Therefore, to make the test comparable, both AKS and Constellation on Azure were running with Standard_DC4as_v5 machines and 1.25 Gbps bandwidth.

    -

    Constellation on Azure and AKS used an MTU of 1500. -Constellation on GCP used an MTU of 8896. GKE used an MTU of 1450.

    -

    The difference in network bandwidth can largely be attributed to two factors.

    - -

    Pod-to-Pod​

    -

    In this scenario, the client Pod connects directly to the server pod via its IP address.

    - -

    The results for "Pod-to-Pod" on Azure are as follows:

    -

    Network Pod2Pod Azure benchmark graph

    -

    The results for "Pod-to-Pod" on GCP are as follows:

    -

    Network Pod2Pod GCP benchmark graph

    -

    Pod-to-Service​

    -

    In this scenario, the client Pod connects to the server Pod via a ClusterIP service. This is more relevant to real-world use cases.

    - -

    The results for "Pod-to-Pod" on Azure are as follows:

    -

    Network Pod2SVC Azure benchmark graph

    -

    The results for "Pod-to-Pod" on GCP are as follows:

    -

    Network Pod2SVC GCP benchmark graph

    -

    In our recent comparison of Constellation on GCP with GKE, Constellation has 58% less TCP bandwidth. However, UDP bandwidth was slightly better with Constellation, thanks to its higher MTU.

    -

    Similarly, when comparing Constellation on Azure with AKS using CVMs, Constellation achieved approximately 10% less TCP and 40% less UDP bandwidth.

    -

    Storage I/O​

    -

    Azure and GCP offer persistent storage for their Kubernetes services AKS and GKE via the Container Storage Interface (CSI). CSI storage in Kubernetes is available via PersistentVolumes (PV) and consumed via PersistentVolumeClaims (PVC). -Upon requesting persistent storage through a PVC, GKE and AKS will provision a PV as defined by a default storage class. -Constellation provides persistent storage on Azure and GCP that's encrypted on the CSI layer. -Similarly, upon a PVC request, Constellation will provision a PV via a default storage class.

    -

    For Constellation on Azure and AKS, the benchmark ran with Azure Disk storage Standard SSD of 400 GiB size. -The DC4as machine type with four cores provides the following maximum performance:

    -
      -
    • 6400 (20000 burst) IOPS
      • -
    • 144 MB/s (600 MB/s burst) throughput
      • -
    -

    However, the performance is bound by the capabilities of the 512 GiB Standard SSD size (the size class of 400 GiB volumes):

    -
      -
    • 500 (600 burst) IOPS
      • -
    • 60 MB/s (150 MB/s burst) throughput
      • -
    -

    For Constellation on GCP and GKE, the benchmark ran with Compute Engine Persistent Disk Storage pd-balanced of 400 GiB size. -The N2D machine type with four cores and pd-balanced provides the following maximum performance:

    -
      -
    • 3,000 read IOPS
      • -
    • 15,000 write IOPS
      • -
    • 240 MB/s read throughput
      • -
    • 240 MB/s write throughput
      • -
    -

    However, the performance is bound by the capabilities of a Zonal balanced PD with 400 GiB size:

    -
      -
    • 2400 read IOPS
      • -
    • 2400 write IOPS
      • -
    • 112 MB/s read throughput
      • -
    • 112 MB/s write throughput
      • -
    -

    The fio benchmark consists of several tests. -The benchmark used Kubestr to run fio in Kubernetes. -The default test performs randomized access patterns that accurately depict worst-case I/O scenarios for most applications.

    -

    The following fio settings were used:

    -
      -
    • No Cloud caching
      • -
    • No OS caching
      • -
    • Single CPU
      • -
    • 60 seconds runtime
      • -
    • 10 seconds ramp-up time
      • -
    • 10 GiB file
      • -
    • IOPS: 4 KB blocks and 128 iodepth
      • -
    • Bandwidth: 1024 KB blocks and 128 iodepth
      • -
    -

    For more details, see the fio test configuration.

    -

    The results for IOPS on Azure are as follows:

    -

    I/O IOPS Azure benchmark graph

    -

    The results for IOPS on GCP are as follows:

    -

    I/O IOPS GCP benchmark graph

    -

    The results for bandwidth on Azure are as follows:

    -

    I/O bandwidth Azure benchmark graph

    -

    The results for bandwidth on GCP are as follows:

    -

    I/O bandwidth GCP benchmark graph

    -

    On GCP, the results exceed the maximum performance guarantees of the chosen disk type. There are two possible explanations for this. The first is that there may be cloud caching in place that isn't configurable. Alternatively, the underlying provisioned disk size may be larger than what was requested, resulting in higher performance boundaries.

    -

    When comparing Constellation on GCP with GKE, Constellation has similar bandwidth but about 10% less IOPS performance. On Azure, Constellation has similar IOPS performance compared to AKS, where both likely hit the maximum storage performance. However, Constellation has approximately 15% less read and write bandwidth.

    -

    Conclusion​

    -

    Despite the added security benefits that Constellation provides, it only incurs a slight performance overhead when compared to managed Kubernetes offerings such as AKS and GKE. In most compute benchmarks, Constellation is on par with it's alternatives. -While it may be slightly slower in certain I/O scenarios due to network and storage encryption, there is ongoing work to reduce this overhead to single digits.

    -

    For instance, storage encryption only adds between 10% to 15% overhead in terms of bandwidth and IOPS. -Meanwhile, the biggest performance impact that Constellation currently faces is network encryption, which can incur up to 58% overhead on a 10 Gbps network. -However, the Cilium team has conducted benchmarks with Cilium using WireGuard encryption on a 100 Gbps network that yielded over 15 Gbps. -We're confident that Constellation will provide a similar level of performance with an upcoming release.

    -

    Overall, Constellation strikes a great balance between security and performance, and we're continuously working to improve its performance capabilities while maintaining its high level of security.

    Product features

    -

    Constellation is a Kubernetes engine that aims to provide the best possible data security in combination with enterprise-grade scalability and reliability features---and a smooth user experience.

    -

    From a security perspective, Constellation implements the Confidential Kubernetes concept and corresponding security features, which shield your entire cluster from the underlying infrastructure.

    -

    From an operational perspective, Constellation provides the following key features:

    -
      -
    • Native support for different clouds: Constellation works on Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and STACKIT. Support for OpenStack-based environments is coming with a future release. Constellation securely interfaces with the cloud infrastructure to provide cluster autoscaling, dynamic persistent volumes, and service load balancing.
      • -
    • High availability: Constellation uses a multi-master architecture with a stacked etcd topology to ensure high availability.
      • -
    • Integrated Day-2 operations: Constellation lets you securely upgrade your cluster to a new release. It also lets you securely recover a failed cluster. Both with a single command.
      • -

    Security benefits and threat model

    -

    Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

    -

    TCB comparison

    -

    Given this background, the following describes the concrete threat classes that Constellation addresses.

    -

    Insider access​

    -

    Employees and third-party contractors of cloud service providers (CSPs) have access to different layers of the cloud infrastructure. -This opens up a large attack surface where workloads and data can be read, copied, or manipulated. With Constellation, Kubernetes deployments are shielded from the infrastructure and thus such accesses are prevented.

    -

    Infrastructure-based attacks​

    -

    Malicious cloud users ("hackers") may break out of their tenancy and access other tenants' data. Advanced attackers may even be able to establish a permanent foothold within the infrastructure and access data over a longer period. Analogously to the insider access scenario, Constellation also prevents access to a deployment's data in this scenario.

    -

    Supply chain attacks​

    -

    Supply chain security is receiving lots of attention recently due to an increasing number of recorded attacks. For instance, a malicious actor could attempt to tamper Constellation node images (including Kubernetes and other software) before they're loaded in the confidential VMs of a cluster. Constellation uses remote attestation in conjunction with public transparency logs to prevent this.

    -

    In the future, Constellation will extend this feature to customer workloads. This will enable cluster owners to create auditable policies that precisely define which containers can run in a given deployment.

    Azure​

    -
      -
    • To allow seamless upgrades on Azure when Kubernetes services of type LoadBalancer are deployed, the target -load balancer in which the cloud-controller-manager creates load balancing rules was changed. Instead of using the load balancer -created and maintained by the CLI's Terraform code, the cloud-controller-manager now creates its own load balancer in Azure. -If your Constellation has services of type LoadBalancer, please remove them before the upgrade and re-apply them -afterward.

    Supply chain levels for software artifacts (SLSA) adoption

    -

    Supply chain Levels for Software Artifacts, or SLSA (salsa) is a framework for improving and grading a project's build system and engineering processes. SLSA focuses on security improvements for source code storage as well as build system definition, execution, and observation. SLSA is structured in four levels. This page describes the adoption of SLSA for Constellation.

    -
    info

    SLSA is still in alpha status. The presented levels and their requirements might change in the future. We will adopt any changes into our engineering processes, as they get defined.

    -

    Level 1 - Adopted​

    -

    Build - Scripted

    -

    All build steps are automated via Bazel and GitHub Actions.

    -

    Provenance - Available

    -

    Provenance for the CLI is generated using the slsa-github-generator.

    -

    Level 2 - Adopted​

    -

    Source - Version Controlled

    -

    Constellation is hosted on GitHub using git.

    -

    Build - Build Service

    -

    All builds are carried out by GitHub Actions.

    -

    Provenance - Authenticated

    -

    Provenance for the CLI is signed using the slsa-github-generator. Learn how to verify the CLI using the signed provenance, before using it for the first time.

    -

    Provenance - Service Generated

    -

    Provenance for the CLI is generated using the slsa-github-generator in GitHub Actions.

    -

    Level 3 - Adopted​

    -

    Source - Verified History

    -

    The Edgeless Systems GitHub organization requires two-factor authentication for all members.

    -

    Source - Retained Indefinitely

    -

    Since we use GitHub to host the repository, an external person can't modify or delete the history. Before a pull request can be merged, an explicit approval from an Edgeless Systems team member is required.

    -

    The same holds true for changes proposed by team members. Each change to main needs to be proposed via a pull request and requires at least one approval.

    -

    The Edgeless Systems GitHub organization admins control these settings and are able to make changes to the repository's history should legal requirements necessitate it. These changes require two-party approval following the obliterate policy.

    -

    Build - Build as Code

    -

    All build files for Constellation are stored in the same repository.

    -

    Build - Ephemeral Environment

    -

    All GitHub Action workflows are executed on GitHub-hosted runners. These runners are only available during workflow.

    -

    We currently don't use self-hosted runners.

    -

    Build - Isolated

    -

    As outlined in the previous section, we use GitHub-hosted runners, which provide a new, isolated and ephemeral environment for each build.

    -

    Additionally, the SLSA GitHub generator itself is run in an isolated workflow with the artifact hash as defined inputs.

    -

    Provenance - Non-falsifiable

    -

    As outlined by SLSA GitHub generator it already fulfills the non-falsifiable requirements for SLSA Level 3. The generated provenance is signed using sigstore with an OIDC based proof of identity.

    -

    Level 4 - In Progress​

    -

    We strive to adopt certain aspect of SLSA Level 4 that support our engineering process. At the same time, SLSA is still in alpha status and the biggest changes to SLSA are expected to be around Level 4.

    Terraform usage

    -

    Terraform is an Infrastructure as Code (IaC) framework to manage cloud resources. This page explains how Constellation uses it internally and how advanced users may manually use it to have more control over the resource creation.

    -
    info

    Information on this page is intended for users who are familiar with Terraform. -It's not required for common usage of Constellation. -See the Terraform documentation if you want to learn more about it.

    -

    Terraform state files​

    -

    Constellation keeps Terraform state files in subdirectories of the workspace together with the corresponding Terraform configuration files and metadata. -The subdirectories are created on the first Constellation CLI action that uses Terraform internally.

    -

    Currently, these subdirectories are:

    -
      -
    • constellation-terraform - Terraform state files for the resources of the Constellation cluster
      • -
    • constellation-iam-terraform - Terraform state files for IAM configuration
      • -
    -

    As with all commands, commands that work with these files (e.g., apply, terminate, iam) have to be executed from the root of the cluster's workspace directory. You usually don't need and shouldn't manipulate or delete the subdirectories manually.

    -

    Interacting with Terraform manually​

    -

    Manual interaction with Terraform state created by Constellation (i.e., via the Terraform CLI) should only be performed by experienced users. It may lead to unrecoverable loss of cloud resources. For the majority of users and use cases, the interaction done by the Constellation CLI is sufficient.

    -

    Terraform debugging​

    -

    To debug Terraform issues, the Constellation CLI offers the tf-log flag. You can set it to any of Terraform's log levels:

    -
      -
    • JSON (JSON-formatted logs at TRACE level)
      • -
    • TRACE
      • -
    • DEBUG
      • -
    • INFO
      • -
    • WARN
      • -
    • ERROR
      • -
    -

    The log output is written to the terraform.log file in the workspace directory. The output is appended to the file on each run.

    caution

    If you want to use cert-manager with Constellation, pay attention to the following to avoid potential pitfalls.

    -

    Constellation ships with cert-manager preinstalled. -The default installation is part of the kube-system namespace, as all other Constellation-managed microservices. -You are free to install more instances of cert-manager into other namespaces. -However, be aware that any new installation needs to use the same version as the one installed with Constellation or rely on the same CRD versions. -Also remember to set the installCRDs value to false when installing new cert-manager instances. -It will create problems if you have two installations of cert-manager depending on different versions of the installed CRDs. -CRDs are cluster-wide resources and cert-manager depends on specific versions of those CRDs for each release.

    -

    Before you can create your cluster, you need to configure the identity and access management (IAM) for your cloud service provider (CSP) and choose machine types for the nodes.

    -

    Creating the configuration file​

    -

    You can generate a configuration file for your CSP by using the following CLI command:

    -
    constellation config generate aws
    -

    This creates the file constellation-conf.yaml in the current directory.

    -

    Choosing a VM type​

    -

    Constellation supports the following VM types:

    -

    By default, Constellation uses m6a.xlarge VMs (4 vCPUs, 16 GB RAM) to create your cluster. -Optionally, you can switch to a different VM type by modifying instanceType in the configuration file. -If you are using the default attestation variant awsSEVSNP, you can use the instance types described in AWS's AMD SEV-SNP docs. -Please mind the region restrictions mentioned in the Getting started section.

    If you are using the attestation variant awsNitroTPM, you can choose any of the nitroTPM-enabled instance types.

    The Constellation CLI can also print the supported instance types with: constellation config instance-types.

    -

    Fill the desired VM type into the instanceType fields in the constellation-conf.yml file.

    -

    Creating additional node groups​

    -

    By default, Constellation creates the node groups control_plane_default and worker_default for control-plane nodes and workers, respectively. -If you require additional control-plane or worker groups with different instance types, zone placements, or disk sizes, you can add additional node groups to the constellation-conf.yml file. -Each node group can be scaled individually.

    -

    Consider the following example for AWS:

    -
    nodeGroups:
      control_plane_default:
        role: control-plane
        instanceType: c6a.xlarge
        stateDiskSizeGB: 30
        stateDiskType: gp3
        zone: eu-west-1c
        initialCount: 3
      worker_default:
        role: worker
        instanceType: c6a.xlarge
        stateDiskSizeGB: 30
        stateDiskType: gp3
        zone: eu-west-1c
        initialCount: 2
      high_cpu:
        role: worker
        instanceType: c6a.24xlarge
        stateDiskSizeGB: 128
        stateDiskType: gp3
        zone: eu-west-1c
        initialCount: 1
    -

    This configuration creates an additional node group high_cpu with a larger instance type and disk.

    -

    You can use the field zone to specify what availability zone nodes of the group are placed in. -On Azure, this field is empty by default and nodes are automatically spread across availability zones. -STACKIT currently offers SEV-enabled CPUs in the eu01-1, eu01-2, and eu01-3 zones. -Consult the documentation of your cloud provider for more information:

    - -

    Choosing a Kubernetes version​

    -

    To learn which Kubernetes versions can be installed with your current CLI, you can run constellation config kubernetes-versions. -See also Constellation's Kubernetes support policy.

    -

    Creating an IAM configuration​

    -

    You can create an IAM configuration for your cluster automatically using the constellation iam create command. -If you already have a Constellation configuration file, you can add the --update-config flag to the command. This writes the needed IAM fields into your configuration. Furthermore, the flag updates the zone/region of the configuration if it hasn't been set yet.

    -

    You must be authenticated with the AWS CLI in the shell session with a user that has the required permissions for IAM creation.

    constellation iam create aws --zone=us-east-2a --prefix=constellTest

    This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created.

    Constellation OS images are currently replicated to the following regions:

      -
    • eu-central-1
      • -
    • eu-west-1
      • -
    • eu-west-3
      • -

    Now that you've configured your CSP, you can create your cluster.

    -

    Deleting an IAM configuration​

    -

    You can keep a created IAM configuration and reuse it for new clusters. Alternatively, you can also delete it if you don't want to use it anymore.

    -

    Delete the IAM configuration by executing the following command in the same directory where you executed constellation iam create (the directory that contains constellation-iam-terraform as a subdirectory):

    -
    constellation iam destroy
    -
    caution

    For Azure, deleting the IAM configuration by executing constellation iam destroy will delete the whole resource group created by constellation iam create. -This also includes any additional resources in the resource group that weren't created by Constellation.

    -

    Creating your cluster happens through multiple phases. -The most significant ones are:

    -
      -
    1. Creating the necessary resources in your cloud environment
      2. -
    2. Bootstrapping the Constellation cluster and setting up a connection
      3. -
    3. Installing the necessary Kubernetes components
      4. -
    -

    constellation apply handles all this in a single command. -You can use the --skip-phases flag to skip specific phases of the process. -For example, if you created the infrastructure manually, you can skip the cloud resource creation phase.

    -

    See the architecture section for details on the inner workings of this process.

    -
    tip

    If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

    -

    Before you create the cluster, make sure to have a valid configuration file.

    -
    constellation apply

    apply stores the state of your cluster's cloud resources in a constellation-terraform directory in your workspace.

    -

    Finally, configure kubectl for your cluster:

    -
    export KUBECONFIG="$PWD/constellation-admin.conf"
    -

    🏁 That's it. You've successfully created a Constellation cluster.

    -

    Troubleshooting​

    -

    In case apply fails, the CLI collects logs from the bootstrapping instance and stores them inside constellation-cluster.log.

    Expose a service

    -

    Constellation integrates the native load balancers of each CSP. Therefore, to expose a service simply create a service of type LoadBalancer.

    -

    Internet-facing LB service on AWS​

    -

    To expose your application service externally you might want to use a Kubernetes Service of type LoadBalancer. On AWS, load-balancing is achieved through the AWS Load Balancer Controller as in the managed EKS.

    -

    Since recent versions, the controller deploy an internal LB by default requiring to set an annotation service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing to have an internet-facing LB. For more details, see the official docs.

    -

    For general information on LB with AWS see Network load balancing on Amazon EKS.

    -
    caution

    Before terminating the cluster, all LB backed services should be deleted, so that the controller can cleanup the related resources.

    Ingress on AWS​

    -

    The AWS Load Balancer Controller also provisions Ingress resources of class alb. -AWS Application Load Balancers (ALBs) can be configured with a target-type. -The target type ip requires using the EKS container network solution, which makes it incompatible with Constellation. -If a service can be exposed on a NodePort, the target type instance can be used.

    Recover your cluster

    -

    Recovery of a Constellation cluster means getting it back into a healthy state after too many concurrent node failures in the control plane. -Reasons for an unhealthy cluster can vary from a power outage, or planned reboot, to migration of nodes and regions. -Recovery events are rare, because Constellation is built for high availability and automatically and securely replaces failed nodes. When a node is replaced, Constellation's control plane first verifies the new node before it sends the node the cryptographic keys required to decrypt its state disk.

    -

    Constellation provides a recovery mechanism for cases where the control plane has failed and is unable to replace nodes. -The constellation recover command securely connects to all nodes in need of recovery using attested TLS and provides them with the keys to decrypt their state disks and continue booting.

    -

    Identify unhealthy clusters​

    -

    The first step to recovery is identifying when a cluster becomes unhealthy. -Usually, this can be first observed when the Kubernetes API server becomes unresponsive.

    -

    You can check the health status of the nodes via the cloud service provider (CSP). -Constellation provides logging information on the boot process and status via serial console output. -In the following, you'll find detailed descriptions for identifying clusters stuck in recovery for each CSP.

    -

    First, open the AWS console to view all Auto Scaling Groups (ASGs) in the region of your cluster. Select the ASG of the control plane <cluster-name>-<UID>-control-plane and check that enough members are in a Running state.

    Second, check the boot logs of these Instances. In the ASG's Instance management view, select each desired instance. In the upper right corner, select Action > Monitor and troubleshoot > Get system log.

    In the serial console output, search for Waiting for decryption key. -Similar output to the following means your node was restarted and needs to decrypt the state disk:

    {"level":"INFO","ts":"2022-09-08T10:21:53Z","caller":"cmd/main.go:55","msg":"Starting disk-mapper","version":"2.0.0","cloudProvider":"gcp"}

    {"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"recoveryServer","caller":"recoveryserver/server.go:59","msg":"Starting RecoveryServer"}

    The node will then try to connect to the JoinService and obtain the decryption key. -If this fails due to an unhealthy control plane, you will see log messages similar to the following:

    {"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"rejoinClient","caller":"rejoinclient/client.go:77","msg":"Received list with JoinService endpoints","endpoints":["192.168.178.4:30090","192.168.178.2:30090"]}

    Recover a cluster​

    -

    Recovering a cluster requires the following parameters:

    -
      -

    -

    Build environment prerequisites​

    -

    The build systems used by Constellation - Bazel and Nix - are designed for deterministic, reproducible builds. -These two dependencies should be the only prerequisites for a successful build. -However, it can't be ruled out completely that peculiarities of the host affect the build result. -Thus, we recommend the following host setup for best results:

    -
      -
    1. A Linux operating system not older than v5.4.
      2. -
    2. The GNU C library not older than v2.31 (avoid musl).
      3. -
    3. GNU coreutils not older than v8.30 (avoid busybox).
      4. -
    4. An ext4 filesystem for building.
      5. -
    5. AppArmor turned off.
      6. -
    -

    This is given, for example, on an Ubuntu 22.04 system, which is also used for reproducibility tests.

    The following instructions outline qualitatively how to reproduce a build. -Constellation implements these instructions in the Reproducible Builds workflow, which continuously tests for reproducibility. -The workflow is a good place to look up specific version numbers and build steps.

    -
      -
    1. -

      Check out the Constellation repository at the tag corresponding to the release.

      -

    Install s3proxy

    -

    Constellation includes a transparent client-side encryption proxy for AWS S3 and compatible stores. -s3proxy encrypts objects before sending them to S3 and automatically decrypts them on retrieval, without requiring changes to your application. -With s3proxy, you can use S3 for storage in a confidential way without having to trust the storage provider.

    -

    Limitations​

    -

    Currently, s3proxy has the following limitations:

    -
      -
    • Only PutObject and GetObject requests are encrypted/decrypted by s3proxy. -By default, s3proxy will block requests that may expose unencrypted data to S3 (e.g. UploadPart). -The allow-multipart flag disables request blocking for evaluation purposes.
      • -
    • Using the Range header on GetObject is currently not supported and will result in an error.
      • -
    -

    These limitations will be removed with future iterations of s3proxy. -If you want to use s3proxy but these limitations stop you from doing so, consider opening an issue.

    -

    Deployment​

    -

    You can add the s3proxy to your Constellation cluster as follows:

    -
      -
    1. Add the Edgeless Systems chart repository: -
      helm repo add edgeless https://helm.edgeless.systems/stable
      helm repo update
      -
      2. -
    2. Set ACCESS_KEY and ACCESS_SECRET to valid credentials you want s3proxy to use to interact with S3.
      3. -
    3. Deploy s3proxy: -
      helm install s3proxy edgeless/s3proxy --set awsAccessKeyID="$ACCESS_KEY" --set awsSecretAccessKey="$ACCESS_SECRET"
      -
      4. -
    -

    If you want to run a demo application, check out the Filestash with s3proxy example.

    -

    Technical details​

    -

    Encryption​

    -

    s3proxy relies on Google's Tink Cryptographic Library to implement cryptographic operations securely. -The used cryptographic primitives are NIST SP 800 38f for key wrapping and AES-GCM with 256 bit keys for data encryption.

    -

    s3proxy uses envelope encryption to encrypt objects. -This means s3proxy uses a key encryption key (KEK) issued by the KeyService to encrypt data encryption keys (DEKs). -Each S3 object is encrypted with its own DEK. -The encrypted DEK is then saved as metadata of the encrypted object. -This enables key rotation of the KEK without re-encrypting the data in S3. -The approach also allows access to objects from different locations, as long as each location has access to the KEK.

    -

    Traffic interception​

    -

    To use s3proxy, you have to redirect your outbound S3 traffic to s3proxy. -This can either be done by modifying your client application or by changing the deployment of your application.

    -

    The necessary deployment modifications are to add DNS redirection and a trusted TLS certificate to the client's trust store. -DNS redirection can be defined for each pod, allowing you to use s3proxy for one application without changing other applications in the same cluster. -Adding a trusted TLS certificate is necessary as clients communicate with s3proxy via HTTPS. -To have your client application trust s3proxy's TLS certificate, the certificate has to be added to the client's certificate trust store. -The Filestash with s3proxy example shows how to do this.

    The public key is also available for download at https://edgeless.systems/es.pub and in the Twitter profile @EdgelessSystems.

    Make sure the key is available in a file named cosign.pub to execute the following examples.

    -

    Verify and download SBOMs​

    -

    The following sections detail how to work with each type of artifact to verify and extract the SBOM.

    -

    Constellation CLI​

    -

    The SBOM for Constellation CLI is made available on the GitHub release page. The SBOM (constellation.spdx.sbom) and corresponding signature (constellation.spdx.sbom.sig) are valid for each Constellation CLI for a given version, regardless of architecture and operating system.

    cosign verify-blob --key cosign.pub --signature constellation.spdx.sbom.sig constellation.spdx.sbom
    -

    Container Images​

    -

    SBOMs for container images are attached to the image using Cosign and uploaded to the same registry.

    -

    As a consumer, use cosign to download and verify the SBOM:

    -
    # Verify and download the attestation statement
    cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.att.json
    # Extract SBOM from attestation statement
    jq -r .payload verification-service.att.json | base64 -d > verification-service.cyclonedx.sbom
    -

    A successful verification should result in similar output:

    -
    $ cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.sbom

    Verification for ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --
    The following checks were performed on each of these signatures:
      - The cosign claims were validated
      - The signatures were verified against the specified public key
    $ jq -r .payload verification-service.sbom | base64 -d > verification-service.cyclonedx.sbom
    -
    note

    This example considers only the verification-service. The same approach works for all containers in the Constellation container registry.

    -

    Vulnerability scanning​

    -

    You can use a plethora of tools to consume SBOMs. This section provides suggestions for tools that are popular and known to produce reliable results, but any tool that consumes SPDX or CycloneDX files should work.

    -

    Syft is able to convert between the two formats in case you require a specific type.

    -

    Grype​

    -

    Grype is a CLI tool that lends itself well for integration into CI/CD systems or local developer machines. It's also able to consume the signed attestation statement directly and does the verification in one go.

    -
    grype att:verification-service.sbom --key cosign.pub --add-cpes-if-none -q
    -

    Dependency Track​

    -

    Dependency Track is one of the oldest and most mature solutions when it comes to managing software inventory and vulnerabilities. Once imported, it continuously scans SBOMs for new vulnerabilities. It supports the CycloneDX format and provides direct guidance on how to comply with U.S. Executive Order 14028.

    Version: Next

    Scale your cluster

    -

    Constellation provides all features of a Kubernetes cluster including scaling and autoscaling.

    -

    Worker node scaling​

    -

    Autoscaling​

    -

    Constellation comes with autoscaling disabled by default. To enable autoscaling, find the scaling group of -worker nodes:

    -
    kubectl get scalinggroups -o json | yq '.items | .[] | select(.spec.role == "Worker") | [{"name": .metadata.name, "nodeGoupName": .spec.nodeGroupName}]'
    -

    This will output a list of scaling groups with the corresponding cloud provider name (name) and the cloud provider agnostic name of the node group (nodeGroupName).

    -

    Then, patch the autoscaling field of the scaling group resource with the desired name to true:

    -
    # Replace <name> with the name of the scaling group you want to enable autoscaling for
    worker_group=<name>
    kubectl patch scalinggroups $worker_group --patch '{"spec":{"autoscaling": true}}' --type='merge'
    kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
    -

    The cluster autoscaler now automatically provisions additional worker nodes so that all pods have a place to run. -You can configure the minimum and maximum number of worker nodes in the scaling group by patching the min or -max fields of the scaling group resource:

    -
    kubectl patch scalinggroups $worker_group --patch '{"spec":{"max": 5}}' --type='merge'
    kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
    -

    The cluster autoscaler will now never provision more than 5 worker nodes.

    -

    If you want to see the autoscaling in action, try to add a deployment with a lot of replicas, like the -following Nginx deployment. The number of replicas needed to trigger the autoscaling depends on the size of -and count of your worker nodes. Wait for the rollout of the deployment to finish and compare the number of -worker nodes before and after the deployment:

    -
    kubectl create deployment nginx --image=nginx --replicas 150
    kubectl -n kube-system get nodes
    kubectl rollout status deployment nginx
    kubectl -n kube-system get nodes
    -

    Manual scaling​

    -

    Alternatively, you can manually scale your cluster up or down:

    -
      -
    1. Go to Auto Scaling Groups and select the worker ASG to scale up.
      2. -
    2. Click Edit
      3. -
    3. Set the new (increased) Desired capacity and Update.
      4. -
    -

    Control-plane node scaling​

    -

    Control-plane nodes can only be scaled manually and only scaled up!

    -

    To increase the number of control-plane nodes, follow these steps:

    -
      -
    1. Go to Auto Scaling Groups and select the control-plane ASG to scale up.
      2. -
    2. Click Edit
      3. -
    3. Set the new (increased) Desired capacity and Update.
      4. -
    -

    If you scale down the number of control-planes nodes, the removed nodes won't be able to exit the etcd cluster correctly. This will endanger the quorum that's required to run a stable Kubernetes control plane.

    Version: Next

    Use persistent storage

    -

    Persistent storage in Kubernetes requires cloud-specific configuration. -For abstraction of container storage, Kubernetes offers volumes, -allowing users to mount storage solutions directly into containers. -The Container Storage Interface (CSI) is the standard interface for exposing arbitrary block and file storage systems into containers in Kubernetes. -Cloud service providers (CSPs) offer their own CSI-based solutions for cloud storage.

    -

    Confidential storage​

    -

    Most cloud storage solutions support encryption, such as GCE Persistent Disks (PD). -Constellation supports the available CSI-based storage options for Kubernetes engines in AWS, Azure, GCP, and STACKIT. -However, their encryption takes place in the storage backend and is managed by the CSP. -Thus, using the default CSI drivers for these storage types means trusting the CSP with your persistent data.

    -

    To address this, Constellation provides CSI drivers for AWS EBS, Azure Disk, GCE PD, and OpenStack Cinder, offering encryption on the node level. They enable transparent encryption for persistent volumes without needing to trust the cloud backend. Plaintext data never leaves the confidential VM context, offering you confidential storage.

    -

    For more details see encrypted persistent storage.

    -

    CSI drivers​

    -

    Constellation supports the following drivers, which offer node-level encryption and optional integrity protection.

    -

    Constellation CSI driver for AWS Elastic Block Store -Mount Elastic Block Store storage volumes into your Constellation cluster. -Follow the instructions on how to install the Constellation CSI driver or check out the repository for more information.

    -

    Note that in case the options above aren't a suitable solution for you, Constellation is compatible with all other CSI-based storage options. For example, you can use AWS EFS, Azure Files, or GCP Filestore with Constellation out of the box. Constellation is just not providing transparent encryption on the node level for these storage types yet.

    -

    Installation​

    -

    The Constellation CLI automatically installs Constellation's CSI driver for the selected CSP in your cluster. -If you don't need a CSI driver or wish to deploy your own, you can disable the automatic installation by setting deployCSIDriver to false in your Constellation config file.

    -

    AWS comes with two storage classes by default.

    For more information on encryption algorithms and key sizes, refer to cryptographic algorithms.

    info

    The default storage class is set to encrypted-rwo for performance reasons. -If you want integrity-protected storage, set the storageClassName parameter of your persistent volume claim to integrity-encrypted-rwo.

    Alternatively, you can create your own storage class with integrity protection enabled by adding csi.storage.k8s.io/fstype: ext4-integrity to the class parameters. -Or use another filesystem by specifying another file system type with the suffix -integrity, e.g., csi.storage.k8s.io/fstype: xfs-integrity.

    Note that volume expansion isn't supported for integrity-protected disks.

    -
      -
    1. -

      Create a persistent volume

      -

      A persistent volume claim is a request for storage with certain properties. -It can refer to a storage class. -The following creates a persistent volume claim, requesting 20 GB of storage via the encrypted-rwo storage class:

      -
      cat <<EOF | kubectl apply -f -
      kind: PersistentVolumeClaim
      apiVersion: v1
      metadata:
        name: pvc-example

      Create a Pod with persistent storage

      -

      You can assign a persistent volume claim to an application in need of persistent storage. -The mounted volume will persist restarts. -The following creates a pod that uses the previously created persistent volume claim:

      -

      EOF
      -
      3. -
    -

    Change the default storage class​

    -

    The default storage class is responsible for all persistent volume claims that don't explicitly request storageClassName. -Constellation creates a storage class with encryption enabled and sets this as the default class. -In case you wish to change it, follow the steps below:

    -
      -
    1. -

      List the storage classes in your cluster:

      -
      kubectl get storageclass
      -

      The output is similar to this:

      -
      NAME                      PROVISIONER                         RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE

      -

      The default storage class is marked by (default).

      -
      2. -
    2. -

      Mark old default storage class as non default

      -

      If you previously used another storage class as the default, you will have to remove that annotation:

      -
      kubectl patch storageclass encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
      -
      3. -
    3. -

      Mark new class as the default

      -
      kubectl patch storageclass integrity-encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
      -
      4. -
    4. -

      Verify that your chosen storage class is default:

    You can terminate your cluster using the CLI. For this, you need the Terraform state directory named constellation-terraform in the current directory.

    -
    danger

    All ephemeral storage and state of your cluster will be lost. Make sure any data is safely stored in persistent storage. Constellation can recreate your cluster and the associated encryption keys, but won't backup your application data automatically.

    -

    Terminate the cluster by running:

    constellation terminate

    Or without confirmation (e.g., for automation purposes):

    constellation terminate --yes

    This deletes all resources created by Constellation in your cloud environment. -All local files created by the apply command are deleted as well, except for constellation-mastersecret.json and the configuration file.

    caution

    Termination can fail if additional resources have been created that depend on the ones managed by Constellation. In this case, you need to delete these additional -resources manually. Just run the terminate command again afterward to continue the termination process of the cluster.

    Use the Terraform provider

    -

    The Constellation Terraform provider allows to manage the full lifecycle of a Constellation cluster (namely creation, upgrades, and deletion) via Terraform. -The provider is available through the Terraform registry and is released in lock-step with Constellation releases.

    -

    Prerequisites​

    -
      -
    • a Linux / Mac operating system (ARM64/AMD64)
      • -
    • a Terraform installation of version v1.4.4 or above
      • -
    -

    Quick setup​

    -

    This example shows how to set up a Constellation cluster with the reference IAM and infrastructure setup. This setup is also used when creating a Constellation cluster through the Constellation CLI. You can either consume the IAM / infrastructure modules through a remote source (recommended) or local files. The latter requires downloading the infrastructure and IAM modules for the corresponding CSP from terraform-modules.zip on the Constellation release page and placing them in the Terraform workspace directory.

    -
      -
    1. Create a directory (workspace) for your Constellation cluster.
      2. -
    -
    mkdir constellation-workspace
    cd constellation-workspace
    -
      -
    1. Use one of the example configurations for using the Constellation Terraform provider or create a main.tf file and fill it with the resources you want to create. The Constellation Terraform provider documentation offers thorough documentation on the resources and their attributes.
      2. -
    2. Initialize and apply the Terraform configuration.
      3. -
    -

    Initialize the providers and apply the configuration.

    terraform init
    terraform apply

    Optionally, you can prefix the terraform apply command with TF_LOG=INFO to collect Terraform logs while applying the configuration. This may provide helpful output in debugging scenarios.

    -
      -
    1. Connect to the cluster.
      2. -
    -
    terraform output -raw kubeconfig > constellation-admin.conf
    export KUBECONFIG=$(realpath constellation-admin.conf)
    -

    Bringing your own infrastructure​

    -

    Instead of using the example infrastructure used in the quick setup, you can also provide your own infrastructure. -If you need a starting point for a custom infrastructure setup, you can download the infrastructure / IAM Terraform modules for the respective CSP from the Constellation GitHub releases. You can modify and extend the modules per your requirements, while keeping the basic functionality intact. -The module contains:

    -
      -
    • {csp}: cloud resources the cluster runs on
      • -
    • iam/{csp}: IAM resources used within the cluster
      • -
    -

    When upgrading your cluster, make sure to check the Constellation release notes for potential breaking changes in the reference infrastructure / IAM modules that need to be considered.

    -

    Cluster upgrades​

    -
    tip

    Also see the general documentation on cluster upgrades.

    -

    The steps for applying the upgrade are as follows:

    -
      -
    1. Update the version constraint of the Constellation Terraform provider in the required_providers block in your Terraform configuration.
      2. -
    2. If you explicitly set any of the version attributes of the provider's resources and data sources (e.g. image_version or constellation_microservice_version), make sure to update them too. Refer to Constellation's version support policy for more information on how each Constellation version and its dependencies are supported.
      3. -
    3. Update the IAM / infrastructure configuration. - -
      4. -
    4. Upgrade the Terraform module and provider dependencies and apply the targeted configuration.
      5. -
    -

    Troubleshooting

    -

    This section aids you in finding problems when working with Constellation.

    -

    Common issues​

    -

    Issues with creating new clusters​

    -

    When you create a new cluster, you should always use the latest release. -If something doesn't work, check out the known issues.

    -

    Azure: Resource Providers can't be registered​

    -

    On Azure, you may receive the following error when running apply or terminate with limited IAM permissions:

    -
    Error: Error ensuring Resource Providers are registered.

    Terraform automatically attempts to register the Resource Providers it supports to
    ensure it's able to provision resources.

    If you don't have permission to register Resource Providers you may wish to use the
    "skip_provider_registration" flag in the Provider block to disable this functionality.

    [...]
    -

    To continue, please ensure that the required resource providers have been registered in your subscription by your administrator.

    -

    Afterward, set ARM_SKIP_PROVIDER_REGISTRATION=true as an environment variable and either run apply or terminate again. -For example:

    -
    ARM_SKIP_PROVIDER_REGISTRATION=true constellation apply
    -

    Or alternatively, for terminate:

    -
    ARM_SKIP_PROVIDER_REGISTRATION=true constellation terminate
    -

    Azure: Can't update attestation policy​

    -

    On Azure, you may receive the following error when running apply from within an Azure environment, e.g., an Azure VM:

    -
    An error occurred: patching policies: updating attestation policy: unexpected status code: 403 Forbidden
    -

    The problem occurs because the Azure SDK we use internally attempts to authenticate towards the Azure API with the managed identity of your current environment instead of the Azure CLI token.

    -

    We decided not to deviate from this behavior and comply with the ordering of credentials.

    -

    A solution is to add the required permissions to the managed identity of your environment. For example, the managed identity of your Azure VM, instead of the account that you've authenticated with in the Azure CLI.

    -

    If your setup requires a change in the ordering of credentials, please open an issue and explain your desired behavior.

    -

    Nodes fail to join with error untrusted measurement value​

    -

    This error indicates that a node's attestation statement contains measurements that don't match the trusted values expected by the JoinService. -This may for example happen if the cloud provider updates the VM's firmware such that it influences the runtime measurements in an unforeseen way. -A failed upgrade due to an erroneous attestation config can also cause this error. -You can change the expected measurements to resolve the failure.

    -
    caution

    Attestation and trusted measurements are crucial for the security of your cluster. -Be extra careful when manually changing these settings. -When in doubt, check if the encountered issue is known or contact support.

    -
    tip

    During an upgrade with modified attestation config, a backup of the current configuration is stored in the join-config config map in the kube-system namespace under the attestationConfig_backup key. To restore the old attestation config after a failed upgrade, replace the value of attestationConfig with the value from attestationConfig_backup:

    kubectl patch configmaps -n kube-system join-config -p "{\"data\":{\"attestationConfig\":\"$(kubectl get configmaps -n kube-system join-config -o "jsonpath={.data.attestationConfig_backup}")\"}}"
    -

    You can use the apply command to change measurements of a running cluster:

    -
      -
    1. Modify the measurements key in your local constellation-conf.yaml to the expected values.
      2. -
    2. Run constellation apply.
      3. -
    -

    Keep in mind that running apply also applies any version changes from your config to the cluster.

    -

    You can run these commands to learn about the versions currently configured in the cluster:

    -
      -

    Upgrading Kubernetes resources fails​

    -

    Constellation manages its Kubernetes resources using Helm. -When applying an upgrade, the charts that are about to be installed, and a values override file overrides.yaml, -are saved to disk in your current workspace under constellation-upgrade/upgrade-<timestamp>/helm-charts/. -If upgrading the charts using the Constellation CLI fails, you can review these charts and try to manually apply the upgrade.

    -
    caution

    Changing and manually applying the charts may destroy cluster resources and can lead to broken Constellation deployments. -Proceed with caution and when in doubt, -check if the encountered issue is known or contact support.

    -

    Diagnosing issues​

    -

    Logs​

    -

    To get started on diagnosing issues with Constellation, it's often helpful to collect logs from nodes, pods, or other resources in the cluster. Most logs are available through Kubernetes' standard -logging interfaces.

    -

    To debug issues occurring at boot time of the nodes, you can use the serial console interface of the CSP while the machine boots to get a read-only view of the boot logs.

    -

    Apart from that, Constellation also offers further observability integrations.

    -

    Node shell access​

    -

    Debugging via a shell on a node is directly supported by Kubernetes.

    -
      -
    1. -

      Figure out which node to connect to:

      -
      kubectl get nodes
      # or to see more information, such as IPs:
      kubectl get nodes -o wide
      -
      2. -
    2. -

      Connect to the node:

      -
      kubectl debug node/constell-worker-xksa0-000000 -it --image=busybox
      -

      You will be presented with a prompt.

      -

      The nodes file system is mounted at /host.

      -
      3. -
    3. -

      Once finished, clean up the debug pod:

      -
      kubectl delete pod node-debugger-constell-worker-xksa0-000000-bjthj
      -
      4. -
    -

    Emergency SSH access​

    -

    Emergency SSH access to nodes can be useful to diagnose issues or download important data even if the Kubernetes API isn't reachable anymore.

    -
      -
    1. -

      Enter the constellation-terraform directory in your Constellation workspace and enable emergency SSH access to the cluster:

      -
       cd constellation-terraform
       echo "emergency_ssh = true" >> ./terraform.tfvars
       terraform apply
      -
      2. -
    2. -

      Sign an existing SSH key with your master secret:

      -
      cd ../ # go back to your Constellation workspace
      constellation ssh --key your_public_key.pub
      -

      A certificate is written to constellation_cert.pub.

      -

      The certificate is valid for 24 hours and enables you to access your Constellation nodes using -certificate based authentication.

      -
      3. -
    3. -

      Now you can connect to any Constellation node using your certificate and your private key.

      -
      ssh -o CertificateFile=constellation_cert.pub -o UserKnownHostsFile=./known_hosts -i <your private key> root@<ip of constellation node>
      -

      Normally, you don't have access to the Constellation nodes since they reside in a private network. -To access those nodes anyways, you can use your Constellation load balancer as a proxy jump host. -For this, use something along the following SSH client configuration:

      -
      Host <LB public IP>
        ProxyJump none

      Host *
        IdentityFile <your private key>
        PreferredAuthentications publickey
        CertificateFile=constellation_cert.pub
        UserKnownHostsFile=./known_hosts
        User root
        ProxyJump <LB public IP>
      -

      With this configuration you can connect to a Constellation node using ssh -F <this config> <private node IP>. -You can obtain the private node IP and the public IP of the load balancer using your CSP's web UI. Note that if -you use the load balancers domain name, ssh host certificate verification doesn't work, so using the public IP is recommended.

    Version: Next

    Use Azure trusted launch VMs

    -

    Constellation also supports trusted launch VMs on Microsoft Azure. Trusted launch VMs don't offer the same level of security as Confidential VMs, but are available in more regions and in larger quantities. The main difference between trusted launch VMs and normal VMs is that the former offer vTPM-based remote attestation. When used with trusted launch VMs, Constellation relies on vTPM-based remote attestation to verify nodes.

    -
    caution

    Trusted launch VMs don't provide runtime encryption and don't keep the cloud service provider (CSP) out of your trusted computing base.

    -

    Constellation supports trusted launch VMs with instance types Standard_D*_v4 and Standard_E*_v4. Run constellation config instance-types for a list of all supported instance types.

    -

    VM images​

    -

    Azure currently doesn't support community galleries for trusted launch VMs. Thus, you need to manually import the Constellation node image into your cloud subscription.

    -

    The latest image is available at https://cdn.confidential.cloud/constellation/images/azure/trusted-launch/v2.2.0/constellation.img. Simply adjust the version number to download a newer version.

    -

    After you've downloaded the image, create a resource group constellation-images in your Azure subscription and import the image. -You can use a script to do this:

    -
    wget https://raw.githubusercontent.com/edgelesssys/constellation/main/hack/importAzure.sh
    chmod +x importAzure.sh
    AZURE_IMAGE_VERSION=2.2.0 AZURE_RESOURCE_GROUP_NAME=constellation-images AZURE_IMAGE_FILE=./constellation.img ./importAzure.sh
    -

    The script creates the following resources:

    -
      -
    1. A new image gallery with the default name constellation-import
      2. -
    2. A new image definition with the default name constellation
      3. -
    3. The actual image with the provided version. In this case 2.2.0
      4. -
    -

    Once the import is completed, use the ID of the image version in your constellation-conf.yaml for the image field. Set confidentialVM to false.

    -

    Fetch the image measurements:

    -
    IMAGE_VERSION=2.2.0
    URL=https://public-edgeless-constellation.s3.us-east-2.amazonaws.com//communitygalleries/constellationcvm-b3782fa0-0df7-4f2f-963e-fc7fc42663df/images/constellation/versions/$IMAGE_VERSION/measurements.yaml
    constellation config fetch-measurements -u$URL -s$URL.sig
    -
    info

    The constellation apply command will issue a warning because manually imported images aren't recognized as production grade images:

    Configured image doesn't look like a released production image. Double check image before deploying to production.

    Please ignore this warning.

    Version: Next

    Upgrade your cluster

    -

    Constellation provides an easy way to upgrade all components of your cluster, without disrupting its availability. -Specifically, you can upgrade the Kubernetes version, the nodes' image, and the Constellation microservices. -You configure the desired versions in your local Constellation configuration and trigger upgrades with the apply command. -To learn about available versions you use the upgrade check command. -Which versions are available depends on the CLI version you are using.

    -

    Update the CLI​

    -

    Each CLI comes with a set of supported microservice and Kubernetes versions. -Most importantly, a given CLI version can only upgrade a cluster of the previous minor version, but not older ones. -This means that you have to upgrade your CLI and cluster one minor version at a time.

    -

    For example, if you are currently on CLI version v2.6 and the latest version is v2.8, you should

    -
      -
    • upgrade the CLI to v2.7,
      • -
    • upgrade the cluster to v2.7,
      • -
    • and only then continue upgrading the CLI (and the cluster) to v2.8 after.
      • -
    -

    Also note that if your current Kubernetes version isn't supported by the next CLI version, use your current CLI to upgrade to a newer Kubernetes version first.

    -

    To learn which Kubernetes versions are supported by a particular CLI, run constellation config kubernetes-versions.

    -

    Migrate the configuration​

    -

    The Constellation configuration file is located in the file constellation-conf.yaml in your workspace. -Refer to the migration reference to check if you need to update fields in your configuration file. -Use constellation config migrate to automatically update an old config file to a new format.

    -

    Check for upgrades​

    -

    To learn which versions the current CLI can upgrade to and what's installed in your cluster, run:

    -
    # Show possible upgrades
    constellation upgrade check

    # Show possible upgrades and write them to config file
    constellation upgrade check --update-config
    -

    You can either enter the reported target versions into your config manually or run the above command with the --update-config flag. -When using this flag, the kubernetesVersion, image, microserviceVersion, and attestation fields are overwritten with the smallest available upgrade.

    -

    Apply the upgrade​

    -

    Once you updated your config with the desired versions, you can trigger the upgrade with this command:

    -
    constellation apply
    -

    Microservice upgrades will be finished within a few minutes, depending on the cluster size. -If you are interested, you can monitor pods restarting in the kube-system namespace with your tool of choice.

    -

    Image and Kubernetes upgrades take longer. -For each node in your cluster, a new node has to be created and joined. -The process usually takes up to ten minutes per node.

    -

    When applying an upgrade, the Helm charts for the upgrade as well as backup files of Constellation-managed Custom Resource Definitions, Custom Resources, and Terraform state are created. -You can use the Terraform state backup to restore previous resources in case an upgrade misconfigured or erroneously deleted a resource. -You can use the Custom Resource (Definition) backup files to restore Custom Resources and Definitions manually (e.g., via kubectl apply) if the automatic migration of those resources fails. -You can use the Helm charts to manually apply upgrades to the Kubernetes resources, should an upgrade fail.

    -
    note

    For advanced users: the upgrade consists of several phases that can be individually skipped through the --skip-phases flag. -The phases are infrastracture for the cloud resource management through Terraform, helm for the chart management of the microservices, image for OS image upgrades, and k8s for Kubernetes version upgrades.

    -

    Check the status​

    -

    Upgrades are asynchronous operations. -After you run apply, it will take a while until the upgrade has completed. -To understand if an upgrade is finished, you can run:

    -
    constellation status
    -

    This command displays the following information:

    -
      -
    • The installed services and their versions
      • -
    • The image and Kubernetes version the cluster is expecting on each node
      • -
    • How many nodes are up to date
      • -
    -

    Here's an example output:

    -
    Target versions:
        Image: v2.6.0
        Kubernetes: v1.25.8
    Service versions:
        Cilium: v1.12.1
        cert-manager: v1.10.0
        constellation-operators: v2.6.0
        constellation-services: v2.6.0
    Cluster status: Some node versions are out of date
        Image: 23/25
        Kubernetes: 25/25
    -

    This output indicates that the cluster is running Kubernetes version 1.25.8, and all nodes have the appropriate binaries installed. -23 out of 25 nodes have already upgraded to the targeted image version of 2.6.0, while two are still in progress.

    -

    Apply further upgrades​

    -

    After the upgrade is finished, you can run constellation upgrade check again to see if there are more upgrades available. If so, repeat the process.

    Edgeless Systems uses sigstore and SLSA to ensure supply-chain security for the Constellation CLI and node images ("artifacts"). sigstore consists of three components: Cosign, Rekor, and Fulcio. Edgeless Systems uses Cosign to sign artifacts. All signatures are uploaded to the public Rekor transparency log, which resides at https://rekor.sigstore.dev.

    -
    note

    The public key for Edgeless Systems' long-term code-signing key is:

    -----BEGIN PUBLIC KEY-----
    MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEf8F1hpmwE+YCFXzjGtaQcrL6XZVT
    JmEe5iSLvG1SyQSAew7WdMKF6o9t8e2TFuCkzlOhhlws2OHWbiFZnFWCFw==
    -----END PUBLIC KEY-----

    The public key is also available for download at https://edgeless.systems/es.pub and in the Twitter profile @EdgelessSystems.

    -

    The Rekor transparency log is a public append-only ledger that verifies and records signatures and associated metadata. The Rekor transparency log enables everyone to observe the sequence of (software) signatures issued by Edgeless Systems and many other parties. The transparency log allows for the public identification of dubious or malicious signatures.

    -

    You should always ensure that (1) your CLI executable was signed with the private key corresponding to the above public key and that (2) there is a corresponding entry in the Rekor transparency log. Both can be done as described in the following.

    -
    info

    You don't need to verify the Constellation node images. This is done automatically by your CLI and the rest of Constellation.

    -

    Verify the signature​

    -
    info

    This guide assumes Linux on an amd64 processor. The exact steps for other platforms differ slightly.

    -

    First, install the Cosign CLI. Next, download and verify the signature that accompanies your CLI executable, for example:

    -
    $ cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

    Verified OK
    -

    The above performs an offline verification of the provided public key, signature, and executable. To also verify that a corresponding entry exists in the public Rekor transparency log, add the variable COSIGN_EXPERIMENTAL=1:

    -
    $ COSIGN_EXPERIMENTAL=1 cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

    tlog entry verified with uuid: afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13 index: 3477047
    Verified OK
    -

    🏁 You now know that your CLI executable was officially released and signed by Edgeless Systems.

    -

    Optional: Manually inspect the transparency log​

    -

    To further inspect the public Rekor transparency log, install the Rekor CLI. A search for the CLI executable should give a single UUID. (Note that this UUID contains the UUID from the previous cosign command.)

    -
    $ rekor-cli search --artifact constellation-linux-amd64

    Found matching entries (listed by UUID):
    362f8ecba72f4326afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13

    -
    rekor-cli search --public-key https://edgeless.systems/es.pub --pki-format x509
    -

    Edgeless Systems monitors this list to detect potential unauthorized use of its private key.

    Verify the provenance​

    -

    Provenance attests that a software artifact was produced by a specific repository and build system invocation. For more information on provenance visit slsa.dev and learn about the adoption of SLSA for Constellation.

    -

    Just as checking its signature proves that the CLI hasn't been manipulated, checking the provenance proves that the artifact was produced by the expected build process and hasn't been tampered with.

    -

    To verify the provenance, first install the slsa-verifier. Then make sure you have the provenance file (constellation.intoto.jsonl) and Constellation CLI downloaded. Both are available on the GitHub release page.

    -
    info

    The same provenance file is valid for all Constellation CLI executables of a given version independent of the target platform.

    -

    Use the verifier to perform the check:

    -
    $ slsa-verifier verify-artifact constellation-linux-amd64 \
      --provenance-path constellation.intoto.jsonl \
      --source-uri github.com/edgelesssys/constellation

    Constellation's attestation feature allows you, or a third party, to verify the integrity and confidentiality of your Constellation cluster.

    -

    Fetch measurements​

    -

    To verify the integrity of Constellation you need trusted measurements to verify against. For each node image released by Edgeless Systems, there are signed measurements, which you can download using the CLI:

    -
    constellation config fetch-measurements
    -

    This command performs the following steps:

    -
      -
    1. Download the signed measurements for the configured image. By default, this will use Edgeless Systems' public measurement registry.
      2. -
    2. Verify the signature of the measurements. This will use Edgeless Systems' public key.
      3. -
    3. Write measurements into configuration file.
      4. -
    -

    The configuration file then contains a list of measurements similar to the following:

    -

    Each entry specifies the expected value of the Constellation node, and whether the measurement should be enforced (warnOnly: false), or only a warning should be logged (warnOnly: true). -By default, the subset of the available measurements that can be locally reproduced and verified is enforced.

    -

    During attestation, the validating side (CLI or join service) compares each measurement reported by the issuing side (first node or joining node) individually. -For mismatching measurements that have set warnOnly to true only a warning is emitted. -For mismatching measurements that have set warnOnly to false an error is emitted and attestation fails. -If attestation fails for a new node, it isn't permitted to join the cluster.

    The verify command​

    -
    note

    The steps below are purely optional. They're automatically executed by constellation apply when you initialize your cluster. The constellation verify command mostly has an illustrative purpose.

    -

    The verify command obtains and verifies an attestation statement from a running Constellation cluster.

    -
    constellation verify [--cluster-id ...]
    -

    From the attestation statement, the command verifies the following properties:

    -
      -
    • The cluster is using the correct Confidential VM (CVM) type.
      • -
    • Inside the CVMs, the correct node images are running. The node images are identified through the measurements obtained in the previous step.
      • -
    • The unique ID of the cluster matches the one from your constellation-state.yaml file or passed in via --cluster-id.
      • -
    -

    Once the above properties are verified, you know that you are talking to the right Constellation cluster and it's in a good and trustworthy shape.

    -

    Custom arguments​

    -

    The verify command also allows you to verify any Constellation deployment that you have network access to. For this you need the following:

    -
      -
    • The IP address of a running Constellation cluster's VerificationService. The VerificationService is exposed via a NodePort service using the external IP address of your cluster. Run kubectl get nodes -o wide and look for EXTERNAL-IP.
      • -
    • The cluster's clusterID. See cluster identity for more details.
      • -
    • A constellation-conf.yaml file with the expected measurements of the cluster in your working directory.
      • -
    -

    For example:

    -
    constellation verify -e 192.0.2.1 --cluster-id Q29uc3RlbGxhdGlvbkRvY3VtZW50YXRpb25TZWNyZXQ=

    Feature status of clouds

    -

    What works on which cloud? Currently, Confidential VMs (CVMs) are available in varying quality on the different clouds and software stacks.

    -

    For Constellation, the ideal environment provides the following:

    -
      -
    1. Ability to run arbitrary software and images inside CVMs
      2. -
    2. CVMs based on AMD SEV-SNP (available in EPYC CPUs since the Milan generation) or Intel TDX (available in Xeon CPUs since the Sapphire Rapids generation)
      3. -
    3. Ability for CVM guests to obtain raw hardware attestation statements
      4. -
    4. Reviewable, open-source firmware inside CVMs
      5. -
    5. Capability of the firmware to attest the integrity of the code it passes control to, e.g., with an embedded virtual TPM (vTPM)
      6. -
    -

    (1) is a functional must-have. (2)--(5) are required for remote attestation that fully keeps the infrastructure/cloud out. Constellation can work without them or with approximations, but won't protect against certain privileged attackers anymore.

    Amazon Web Services (AWS)​

    -

    Amazon EC2 supports AMD SEV-SNP. -Regarding (3), AWS provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the NitroTPM for measured boot, which is a vTPM managed by the Nitro hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the firmware is open source and can be reproducibly built.

    -

    Microsoft Azure​

    -

    With its CVM offering, Azure provides the best foundations for Constellation. -Regarding (3), Azure provides direct access to attestation statements. -The firmware runs in an isolated domain inside the CVM and exposes a vTPM (5), but it's closed source (4). -On SEV-SNP, Azure uses VM Privilege Level (VMPL) isolation for the separation of firmware and the rest of the VM; on TDX, they use TD partitioning. -This firmware is signed by Azure. -The signature is reflected in the attestation statements of CVMs. -Thus, the Azure closed-source firmware becomes part of Constellation's trusted computing base (TCB).

    -

    * Recently, Azure announced the open source paravisor OpenHCL. It's the foundation for fully open source and verifiable CVM firmware. Once Azure provides their CVM firmware with reproducible builds based on OpenHCL, (4) switches from No to Yes. Constellation will support OpenHCL based firmware on Azure in the future.

    -

    Google Cloud Platform (GCP)​

    -

    The CVMs Generally Available in GCP are based on AMD SEV-ES or SEV-SNP. -Regarding (3), with their SEV-SNP offering Google provides direct access to attestation statements. -However, regarding (5), attestation is partially based on the Shielded VM vTPM for measured boot, which is a vTPM managed by Google's hypervisor. -Hence, the hypervisor is currently part of Constellation's TCB. -Regarding (4), the CVMs still include closed-source firmware.

    -

    TDX on Google is in public preview. -With it, Constellation would have a similar TCB and attestation flow as with the current SEV-SNP offering.

    -

    STACKIT​

    -

    STACKIT Compute Engine supports AMD SEV-ES. A vTPM is used for measured boot, which is a vTPM managed by STACKIT's hypervisor. Hence, the hypervisor is currently part of Constellation's TCB.

    -

    OpenStack​

    -

    OpenStack is an open-source cloud and infrastructure management software. It's used by many smaller CSPs and datacenters. In the latest Yoga version, OpenStack has basic support for CVMs. However, much depends on the employed kernel and hypervisor. Features (2)--(4) are likely to be a Yes with Linux kernel version 6.2. Thus, going forward, OpenStack on corresponding AMD or Intel hardware will be a viable underpinning for Constellation.

    -

    Conclusion​

    -

    The different clouds and software like the Linux kernel and OpenStack are in the process of building out their support for state-of-the-art CVMs. Azure has already most features in place. For Constellation, the status quo means that the TCB has different shapes on different infrastructures. With broad SEV-SNP support coming to the Linux kernel, we soon expect a normalization of features across infrastructures.

    Confidential Kubernetes

    -

    We use the term Confidential Kubernetes to refer to the concept of using confidential-computing technology to shield entire Kubernetes clusters from the infrastructure. The three defining properties of this concept are:

    -
      -
    1. Workload shielding: the confidentiality and integrity of all workload-related data and code are enforced.
      2. -
    2. Control plane shielding: the confidentiality and integrity of the cluster's control plane, state, and workload configuration are enforced.
      3. -
    3. Attestation and verifiability: the two properties above can be verified remotely based on hardware-rooted cryptographic certificates.
      4. -
    -

    Each of the above properties is equally important. Only with all three in conjunction, an entire cluster can be shielded without gaps.

    -

    Constellation security features​

    -

    Constellation implements the Confidential Kubernetes concept with the following security features.

    -
      -
    • Runtime encryption: Constellation runs all Kubernetes nodes inside Confidential VMs (CVMs). This gives runtime encryption for the entire cluster.
      • -
    • Network and storage encryption: Constellation augments this with transparent encryption of the network, persistent storage, and other managed storage like AWS S3. Thus, workloads and control plane are truly end-to-end encrypted: at rest, in transit, and at runtime.
      • -
    • Transparent key management: Constellation manages the corresponding cryptographic keys inside CVMs.
      • -
    • Node attestation and verification: Constellation verifies the integrity of each new CVM-based node using remote attestation. Only "good" nodes receive the cryptographic keys required to access the network and storage of a cluster.
      • -
    • Confidential computing-optimized images: A node is "good" if it's running a signed Constellation node image inside a CVM and is in the expected state. (Node images are hardware-measured during boot. The measurements are reflected in the attestation statements that are produced by nodes and verified by Constellation.)
      • -
    • "Whole cluster" attestation: Towards the DevOps engineer, Constellation provides a single hardware-rooted certificate from which all of the above can be verified.
      • -
    -

    With the above, Constellation wraps an entire cluster into one coherent and verifiable confidential context. The concept is depicted in the following.

    -

    Confidential Kubernetes

    -

    Comparison: Managed Kubernetes with CVMs​

    -

    In comparison, managed Kubernetes with CVMs, as it's for example offered in AKS and GKE, only provides runtime encryption for certain worker nodes. Here, each worker node is a separate (and typically unverified) confidential context. This only provides limited security benefits as it only prevents direct access to a worker node's memory. The large majority of potential attacks through the infrastructure remain unaffected. This includes attacks through the control plane, access to external key management, and the corruption of worker node images. This leaves many problems unsolved. For instance, Node A has no means to verify if Node B is "good" and if it's OK to share data with it. Consequently, this approach leaves a large attack surface, as is depicted in the following.

    HashiCorp Vault is a distributed secrets management software that can be deployed to Kubernetes. -HashiCorp maintains a benchmarking tool for vault, vault-benchmark. -Vault-benchmark generates load on a Vault deployment and measures response times.

    -

    This article describes the results from running vault-benchmark on Constellation, AKS, and GKE. -You can find the setup for producing the data discussed in this article in the vault-benchmarks repository.

    -

    The Vault API used during benchmarking is the transits secret engine. -This allows services to send data to Vault for encryption, decryption, signing, and verification.

    -

    Results​

    -

    On each run, vault-benchmark sends requests and measures the latencies. -The measured latencies are aggregated through various statistical features. -After running the benchmark n times, the arithmetic mean over a subset of the reported statistics is calculated. -The selected features are arithmetic mean, 99th percentile, minimum, and maximum.

    -

    Arithmetic mean gives a general sense of the latency on each target. -The 99th percentile shows performance in (most likely) erroneous states. -Minimum and maximum mark the range within which latency varies each run.

    -

    The benchmark was configured with 1300 workers and 10 seconds per run. -Those numbers were chosen empirically. -The latency was stabilizing at 10 seconds runtime, not changing with further increase. -Increasing the number of workers beyond 1300 leads to request failures, marking the limit Vault was able to handle in this setup. -All results are based on 100 runs.

    -

    The following data was generated while running five replicas, one primary, and four standby nodes. -All numbers are in seconds if not indicated otherwise.

    AMD and Azure benchmarking​

    -

    AMD and Azure have collectively released a performance benchmark for CVMs that utilize 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. This benchmark, which included a variety of mostly compute-intensive tests such as SPEC CPU 2017 and CoreMark, demonstrated that CVMs experience only minor performance degradation (ranging from 2% to 8%) when compared to standard VMs. Such results are indicative of the performance that can be expected from compute-intensive workloads running with Constellation on Azure.

    Similarly, AMD and Google have jointly released a performance benchmark for CVMs employing 3rd Gen AMD EPYC processors (Milan) with SEV-SNP. With high-performance computing workloads such as WRF, NAMD, Ansys CFS, and Ansys LS_DYNA, they observed analogous findings, with only minor performance degradation (between 2% and 4%) compared to standard VMs. These outcomes are reflective of the performance that can be expected for compute-intensive workloads running with Constellation on GCP.

    Network​

    -

    This section gives a thorough analysis of the network performance of Constellation, specifically focusing on measuring TCP and UDP bandwidth. -The benchmark measured the bandwidth of pod-to-pod and pod-to-service connections between two different nodes using iperf.

    -

    GKE and Constellation on GCP had a maximum network bandwidth of 10 Gbps. -AKS with Standard_D4as_v5 machines a maximum network bandwidth of 12.5 Gbps. -The Confidential VM equivalent Standard_DC4as_v5 currently has a network bandwidth of 1.25 Gbps. -Therefore, to make the test comparable, both AKS and Constellation on Azure were running with Standard_DC4as_v5 machines and 1.25 Gbps bandwidth.

    -

    Constellation on Azure and AKS used an MTU of 1500. -Constellation on GCP used an MTU of 8896. GKE used an MTU of 1450.

    -

    The difference in network bandwidth can largely be attributed to two factors.

    In our recent comparison of Constellation on GCP with GKE, Constellation has 58% less TCP bandwidth. However, UDP bandwidth was slightly better with Constellation, thanks to its higher MTU.

    -

    Similarly, when comparing Constellation on Azure with AKS using CVMs, Constellation achieved approximately 10% less TCP and 40% less UDP bandwidth.

    -

    Storage I/O​

    -

    Azure and GCP offer persistent storage for their Kubernetes services AKS and GKE via the Container Storage Interface (CSI). CSI storage in Kubernetes is available via PersistentVolumes (PV) and consumed via PersistentVolumeClaims (PVC). -Upon requesting persistent storage through a PVC, GKE and AKS will provision a PV as defined by a default storage class. -Constellation provides persistent storage on Azure and GCP that's encrypted on the CSI layer. -Similarly, upon a PVC request, Constellation will provision a PV via a default storage class.

    -

    For Constellation on Azure and AKS, the benchmark ran with Azure Disk storage Standard SSD of 400 GiB size. -The DC4as machine type with four cores provides the following maximum performance:

    -
      -
    • 6400 (20000 burst) IOPS
      • -
    • 144 MB/s (600 MB/s burst) throughput
      • -
    -

    However, the performance is bound by the capabilities of the 512 GiB Standard SSD size (the size class of 400 GiB volumes):

    -
      -
    • 500 (600 burst) IOPS
      • -
    • 60 MB/s (150 MB/s burst) throughput
      • -
    -

    For Constellation on GCP and GKE, the benchmark ran with Compute Engine Persistent Disk Storage pd-balanced of 400 GiB size. -The N2D machine type with four cores and pd-balanced provides the following maximum performance:

    -
      -
    • 3,000 read IOPS
      • -
    • 15,000 write IOPS
      • -
    • 240 MB/s read throughput
      • -
    • 240 MB/s write throughput
      • -
    -

    However, the performance is bound by the capabilities of a Zonal balanced PD with 400 GiB size:

    -
      -
    • 2400 read IOPS
      • -
    • 2400 write IOPS
      • -
    • 112 MB/s read throughput
      • -
    • 112 MB/s write throughput
      • -
    -

    The fio benchmark consists of several tests. -The benchmark used Kubestr to run fio in Kubernetes. -The default test performs randomized access patterns that accurately depict worst-case I/O scenarios for most applications.

    -

    The following fio settings were used:

    -
      -
    • No Cloud caching
      • -
    • No OS caching
      • -
    • Single CPU
      • -
    • 60 seconds runtime
      • -
    • 10 seconds ramp-up time
      • -
    • 10 GiB file
      • -
    • IOPS: 4 KB blocks and 128 iodepth
      • -
    • Bandwidth: 1024 KB blocks and 128 iodepth
      • -
    -

    For more details, see the fio test configuration.

    -

    The results for IOPS on Azure are as follows:

    -

    I/O IOPS Azure benchmark graph

    -

    The results for IOPS on GCP are as follows:

    -

    I/O IOPS GCP benchmark graph

    -

    The results for bandwidth on Azure are as follows:

    -

    I/O bandwidth Azure benchmark graph

    -

    The results for bandwidth on GCP are as follows:

    -

    I/O bandwidth GCP benchmark graph

    -

    On GCP, the results exceed the maximum performance guarantees of the chosen disk type. There are two possible explanations for this. The first is that there may be cloud caching in place that isn't configurable. Alternatively, the underlying provisioned disk size may be larger than what was requested, resulting in higher performance boundaries.

    -

    When comparing Constellation on GCP with GKE, Constellation has similar bandwidth but about 10% less IOPS performance. On Azure, Constellation has similar IOPS performance compared to AKS, where both likely hit the maximum storage performance. However, Constellation has approximately 15% less read and write bandwidth.

    -

    Conclusion​

    -

    Despite the added security benefits that Constellation provides, it only incurs a slight performance overhead when compared to managed Kubernetes offerings such as AKS and GKE. In most compute benchmarks, Constellation is on par with it's alternatives. -While it may be slightly slower in certain I/O scenarios due to network and storage encryption, there is ongoing work to reduce this overhead to single digits.

    -

    For instance, storage encryption only adds between 10% to 15% overhead in terms of bandwidth and IOPS. -Meanwhile, the biggest performance impact that Constellation currently faces is network encryption, which can incur up to 58% overhead on a 10 Gbps network. -However, the Cilium team has conducted benchmarks with Cilium using WireGuard encryption on a 100 Gbps network that yielded over 15 Gbps. -We're confident that Constellation will provide a similar level of performance with an upcoming release.

    -

    Overall, Constellation strikes a great balance between security and performance, and we're continuously working to improve its performance capabilities while maintaining its high level of security.

    Product features

    -

    Constellation is a Kubernetes engine that aims to provide the best possible data security in combination with enterprise-grade scalability and reliability features---and a smooth user experience.

    -

    From a security perspective, Constellation implements the Confidential Kubernetes concept and corresponding security features, which shield your entire cluster from the underlying infrastructure.

    -

    From an operational perspective, Constellation provides the following key features:

    -
      -
    • Native support for different clouds: Constellation works on Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and STACKIT. Support for OpenStack-based environments is coming with a future release. Constellation securely interfaces with the cloud infrastructure to provide cluster autoscaling, dynamic persistent volumes, and service load balancing.
      • -
    • High availability: Constellation uses a multi-master architecture with a stacked etcd topology to ensure high availability.
      • -
    • Integrated Day-2 operations: Constellation lets you securely upgrade your cluster to a new release. It also lets you securely recover a failed cluster. Both with a single command.
      • -
    • Support for Terraform: Constellation includes a Terraform provider that lets you manage the full lifecycle of your cluster via Terraform.

    Security benefits and threat model

    -

    Constellation implements the Confidential Kubernetes concept and shields entire Kubernetes deployments from the infrastructure. More concretely, Constellation decreases the size of the trusted computing base (TCB) of a Kubernetes deployment. The TCB is the totality of elements in a computing environment that must be trusted not to be compromised. A smaller TCB results in a smaller attack surface. The following diagram shows how Constellation removes the cloud & datacenter infrastructure and the physical hosts, including the hypervisor, the host OS, and other components, from the TCB (red). Inside the confidential context (green), Kubernetes remains part of the TCB, but its integrity is attested and can be verified.

    -

    TCB comparison

    -

    Given this background, the following describes the concrete threat classes that Constellation addresses.

    -

    Insider access​

    -

    Employees and third-party contractors of cloud service providers (CSPs) have access to different layers of the cloud infrastructure. -This opens up a large attack surface where workloads and data can be read, copied, or manipulated. With Constellation, Kubernetes deployments are shielded from the infrastructure and thus such accesses are prevented.

    -

    Infrastructure-based attacks​

    -

    Malicious cloud users ("hackers") may break out of their tenancy and access other tenants' data. Advanced attackers may even be able to establish a permanent foothold within the infrastructure and access data over a longer period. Analogously to the insider access scenario, Constellation also prevents access to a deployment's data in this scenario.

    -

    Supply chain attacks​

    -

    Supply chain security is receiving lots of attention recently due to an increasing number of recorded attacks. For instance, a malicious actor could attempt to tamper Constellation node images (including Kubernetes and other software) before they're loaded in the confidential VMs of a cluster. Constellation uses remote attestation in conjunction with public transparency logs to prevent this.

    -

    In the future, Constellation will extend this feature to customer workloads. This will enable cluster owners to create auditable policies that precisely define which containers can run in a given deployment.

    Migrations

    -

    This document describes breaking changes and migrations between Constellation releases. -Use constellation config migrate to automatically update an old config file to a new format.

    -

    Migrations to v2.23.0​

    -

    GCP​

    -

    GCP will require the additional permission compute.forwardingRules.list. Please update your IAM roles using constellation iam upgrade apply.

    -

    Migrations to v2.19.1​

    -

    Azure​

    -
      -
    • During the upgrade, security rules are migrated and the old ones need to be cleaned up manually by the user. The below script shows how to delete them through the Azure CLI:
      • -
    -
    #!/usr/bin/env bash
    name="<insert>"  # the name provided in the config
    uid="<insert>"    # the cluster id can be retrieved via `yq '.infrastructure.uid' constellation-state.yaml`
    resource_group="<insert>" # the RG can be retrieved via `yq '.provider.azure.resourceGroup' constellation-conf.yaml`

    rules=(

    Migrating from CLI versions before 2.21.1​

    -

    AWS​

    -
      -
    • AWS clusters that use LoadBalancer resources require more IAM permissions. Please upgrade your IAM roles using constellation iam upgrade apply. This will show necessary changes and apply them, if desired.
      • -
    -

    Migrating from CLI versions before 2.19.0​

    -

    Azure​

    -
      -
    • To allow seamless upgrades on Azure when Kubernetes services of type LoadBalancer are deployed, the target -load balancer in which the cloud-controller-manager creates load balancing rules was changed. Instead of using the load balancer -created and maintained by the CLI's Terraform code, the cloud-controller-manager now creates its own load balancer in Azure. -If your Constellation has services of type LoadBalancer, please remove them before the upgrade and re-apply them -afterward.
      • -
    -

    Migrating from CLI versions before 2.18.0​

    -
      -
    • The provider.azure.appClientID and provider.azure.appClientSecret fields are no longer supported and should be removed.
      • -
    • To keep using an existing UAMI, add the Owner permission with the scope of your resourceGroup.
      • -
    • Otherwise, simply create new Constellation IAM credentials and use the created UAMI.
      • -
    • To migrate the authentication for an existing cluster on Azure to an UAMI with the necessary permissions: -
        -
      1. Remove the aadClientId and aadClientSecret from the azureconfig secret.
        2. -
      2. Set useManagedIdentityExtension to true and use the userAssignedIdentity from the Constellation config for the value of userAssignedIdentityID.
        3. -
      3. Restart the CSI driver, cloud controller manager, cluster autoscaler, and Constellation operator pods.
        4. -
      -
      • -
    -

    Migrating from CLI versions before 2.10​

    -
      -
    • AWS cluster upgrades require additional IAM permissions for the newly introduced aws-load-balancer-controller. Please upgrade your IAM roles using iam upgrade apply. This will show necessary changes and apply them, if desired.
      • -
    • The global nodeGroups field was added.
      • -
    • The fields instanceType, stateDiskSizeGB, and stateDiskType for each cloud provider are now part of the configuration of individual node groups.
      • -
    • The constellation create command no longer uses the flags --control-plane-count and --worker-count. Instead, the initial node count is configured per node group in the nodeGroups field.
      • -
    -

    Migrating from CLI versions before 2.9​

    -
      -
    • The provider.azure.appClientID and provider.azure.clientSecretValue fields were removed to enforce migration to managed identity authentication
      • -
    -

    Migrating from CLI versions before 2.8​

    -
      -
    • The measurements field for each cloud service provider was replaced with a global attestation field.
      • -
    • The confidentialVM, idKeyDigest, and enforceIdKeyDigest fields for the Azure cloud service provider were removed in favor of using the global attestation field.
      • -
    • The optional global field attestationVariant was replaced by the now required attestation field.
      • -
    -

    Migrating from CLI versions before 2.3​

    -
      -
    • -

      The sshUsers field was deprecated in v2.2 and has been removed from the configuration in v2.3. -As an alternative for SSH, check the workflow section Connect to nodes.

      -
      • -

    Supply chain levels for software artifacts (SLSA) adoption

    -

    Supply chain Levels for Software Artifacts, or SLSA (salsa) is a framework for improving and grading a project's build system and engineering processes. SLSA focuses on security improvements for source code storage as well as build system definition, execution, and observation. SLSA is structured in four levels. This page describes the adoption of SLSA for Constellation.

    -
    info

    SLSA is still in alpha status. The presented levels and their requirements might change in the future. We will adopt any changes into our engineering processes, as they get defined.

    -

    Level 1 - Adopted​

    -

    Build - Scripted

    -

    All build steps are automated via Bazel and GitHub Actions.

    -

    Provenance - Available

    -

    Provenance for the CLI is generated using the slsa-github-generator.

    -

    Level 2 - Adopted​

    -

    Source - Version Controlled

    -

    Constellation is hosted on GitHub using git.

    -

    Build - Build Service

    -

    All builds are carried out by GitHub Actions.

    -

    Provenance - Authenticated

    -

    Provenance for the CLI is signed using the slsa-github-generator. Learn how to verify the CLI using the signed provenance, before using it for the first time.

    -

    Provenance - Service Generated

    -

    Provenance for the CLI is generated using the slsa-github-generator in GitHub Actions.

    -

    Level 3 - Adopted​

    -

    Source - Verified History

    -

    The Edgeless Systems GitHub organization requires two-factor authentication for all members.

    -

    Source - Retained Indefinitely

    -

    Since we use GitHub to host the repository, an external person can't modify or delete the history. Before a pull request can be merged, an explicit approval from an Edgeless Systems team member is required.

    -

    The same holds true for changes proposed by team members. Each change to main needs to be proposed via a pull request and requires at least one approval.

    -

    The Edgeless Systems GitHub organization admins control these settings and are able to make changes to the repository's history should legal requirements necessitate it. These changes require two-party approval following the obliterate policy.

    -

    Build - Build as Code

    -

    All build files for Constellation are stored in the same repository.

    -

    Build - Ephemeral Environment

    -

    All GitHub Action workflows are executed on GitHub-hosted runners. These runners are only available during workflow.

    -

    We currently don't use self-hosted runners.

    -

    Build - Isolated

    -

    As outlined in the previous section, we use GitHub-hosted runners, which provide a new, isolated and ephemeral environment for each build.

    -

    Additionally, the SLSA GitHub generator itself is run in an isolated workflow with the artifact hash as defined inputs.

    -

    Provenance - Non-falsifiable

    -

    As outlined by SLSA GitHub generator it already fulfills the non-falsifiable requirements for SLSA Level 3. The generated provenance is signed using sigstore with an OIDC based proof of identity.

    -

    Level 4 - In Progress​

    -

    We strive to adopt certain aspect of SLSA Level 4 that support our engineering process. At the same time, SLSA is still in alpha status and the biggest changes to SLSA are expected to be around Level 4.

    Version: 2.24

    Terraform usage

    -

    Terraform is an Infrastructure as Code (IaC) framework to manage cloud resources. This page explains how Constellation uses it internally and how advanced users may manually use it to have more control over the resource creation.

    -
    info

    Information on this page is intended for users who are familiar with Terraform. -It's not required for common usage of Constellation. -See the Terraform documentation if you want to learn more about it.

    -

    Terraform state files​

    -

    Constellation keeps Terraform state files in subdirectories of the workspace together with the corresponding Terraform configuration files and metadata. -The subdirectories are created on the first Constellation CLI action that uses Terraform internally.

    -

    Currently, these subdirectories are:

    -
      -
    • constellation-terraform - Terraform state files for the resources of the Constellation cluster
      • -
    • constellation-iam-terraform - Terraform state files for IAM configuration
      • -
    -

    As with all commands, commands that work with these files (e.g., apply, terminate, iam) have to be executed from the root of the cluster's workspace directory. You usually don't need and shouldn't manipulate or delete the subdirectories manually.

    -

    Interacting with Terraform manually​

    -

    Manual interaction with Terraform state created by Constellation (i.e., via the Terraform CLI) should only be performed by experienced users. It may lead to unrecoverable loss of cloud resources. For the majority of users and use cases, the interaction done by the Constellation CLI is sufficient.

    -

    Terraform debugging​

    -

    To debug Terraform issues, the Constellation CLI offers the tf-log flag. You can set it to any of Terraform's log levels:

    -
      -
    • JSON (JSON-formatted logs at TRACE level)
      • -
    • TRACE
      • -
    • DEBUG
      • -
    • INFO
      • -
    • WARN
      • -
    • ERROR
      • -
    -

    The log output is written to the terraform.log file in the workspace directory. The output is appended to the file on each run.

    Install cert-manager

    -
    caution

    If you want to use cert-manager with Constellation, pay attention to the following to avoid potential pitfalls.

    -

    Constellation ships with cert-manager preinstalled. -The default installation is part of the kube-system namespace, as all other Constellation-managed microservices. -You are free to install more instances of cert-manager into other namespaces. -However, be aware that any new installation needs to use the same version as the one installed with Constellation or rely on the same CRD versions. -Also remember to set the installCRDs value to false when installing new cert-manager instances. -It will create problems if you have two installations of cert-manager depending on different versions of the installed CRDs. -CRDs are cluster-wide resources and cert-manager depends on specific versions of those CRDs for each release.

    -

    Before you can create your cluster, you need to configure the identity and access management (IAM) for your cloud service provider (CSP) and choose machine types for the nodes.

    -

    Creating the configuration file​

    -

    You can generate a configuration file for your CSP by using the following CLI command:

    -
    constellation config generate aws
    -

    This creates the file constellation-conf.yaml in the current directory.

    -

    Choosing a VM type​

    -

    Constellation supports the following VM types:

    -

    By default, Constellation uses m6a.xlarge VMs (4 vCPUs, 16 GB RAM) to create your cluster. -Optionally, you can switch to a different VM type by modifying instanceType in the configuration file. -If you are using the default attestation variant awsSEVSNP, you can use the instance types described in AWS's AMD SEV-SNP docs. -Please mind the region restrictions mentioned in the Getting started section.

    If you are using the attestation variant awsNitroTPM, you can choose any of the nitroTPM-enabled instance types.

    The Constellation CLI can also print the supported instance types with: constellation config instance-types.

    -

    Fill the desired VM type into the instanceType fields in the constellation-conf.yml file.

    -

    Creating additional node groups​

    -

    By default, Constellation creates the node groups control_plane_default and worker_default for control-plane nodes and workers, respectively. -If you require additional control-plane or worker groups with different instance types, zone placements, or disk sizes, you can add additional node groups to the constellation-conf.yml file. -Each node group can be scaled individually.

    -

    Consider the following example for AWS:

    -
    nodeGroups:
      control_plane_default:
        role: control-plane
        instanceType: c6a.xlarge
        stateDiskSizeGB: 30
        stateDiskType: gp3
        zone: eu-west-1c
        initialCount: 3
      worker_default:
        role: worker
        instanceType: c6a.xlarge
        stateDiskSizeGB: 30
        stateDiskType: gp3
        zone: eu-west-1c
        initialCount: 2
      high_cpu:
        role: worker
        instanceType: c6a.24xlarge
        stateDiskSizeGB: 128
        stateDiskType: gp3
        zone: eu-west-1c
        initialCount: 1
    -

    This configuration creates an additional node group high_cpu with a larger instance type and disk.

    -

    You can use the field zone to specify what availability zone nodes of the group are placed in. -On Azure, this field is empty by default and nodes are automatically spread across availability zones. -STACKIT currently offers SEV-enabled CPUs in the eu01-1, eu01-2, and eu01-3 zones. -Consult the documentation of your cloud provider for more information:

    - -

    Choosing a Kubernetes version​

    To learn which Kubernetes versions can be installed with your current CLI, you can run constellation config kubernetes-versions. -See also Constellation's Kubernetes support policy.

    Creating an IAM configuration​

    -

    You can create an IAM configuration for your cluster automatically using the constellation iam create command. -If you already have a Constellation configuration file, you can add the --update-config flag to the command. This writes the needed IAM fields into your configuration. Furthermore, the flag updates the zone/region of the configuration if it hasn't been set yet.

    -

    You must be authenticated with the AWS CLI in the shell session with a user that has the required permissions for IAM creation.

    constellation iam create aws --zone=us-east-2a --prefix=constellTest

    This command creates IAM configuration for the AWS zone us-east-2a using the prefix constellTest for all named resources being created.

    Constellation OS images are currently replicated to the following regions:

      -
    • eu-central-1
      • -
    • eu-west-1
      • -
    • eu-west-3
      • -
    • us-east-2
      • -
    • ap-south-1
      • -

    If you require the OS image to be available in another region, let us know.

    You can find a list of all regions in AWS's documentation.

    Paste the output into the corresponding fields of the constellation-conf.yaml file.

    -
    Alternatively, you can manually create the IAM configuration on your CSP.

    The following describes the configuration fields and how you obtain the required information or create the required resources.

      iamProfileWorkerNodes: The name of an IAM instance profile attached to all worker nodes.

      -

      You can create the resource with Terraform. For that, use the provided Terraform script to generate the necessary profile. The profile name will be provided as Terraform output value: worker_nodes_instance_profile_name.

      -

    Now that you've configured your CSP, you can create your cluster.

    -

    Deleting an IAM configuration​

    -

    You can keep a created IAM configuration and reuse it for new clusters. Alternatively, you can also delete it if you don't want to use it anymore.

    -

    Delete the IAM configuration by executing the following command in the same directory where you executed constellation iam create (the directory that contains constellation-iam-terraform as a subdirectory):

    -
    constellation iam destroy
    -
    caution

    For Azure, deleting the IAM configuration by executing constellation iam destroy will delete the whole resource group created by constellation iam create. -This also includes any additional resources in the resource group that weren't created by Constellation.

    -

    Creating your cluster happens through multiple phases. -The most significant ones are:

    -
      -
    1. Creating the necessary resources in your cloud environment
      2. -
    2. Bootstrapping the Constellation cluster and setting up a connection
      3. -
    3. Installing the necessary Kubernetes components
      4. -
    -

    constellation apply handles all this in a single command. -You can use the --skip-phases flag to skip specific phases of the process. -For example, if you created the infrastructure manually, you can skip the cloud resource creation phase.

    -

    See the architecture section for details on the inner workings of this process.

    -
    tip

    If you don't have a cloud subscription, you can also set up a local Constellation cluster using virtualization for testing.

    -

    Before you create the cluster, make sure to have a valid configuration file.

    -
    constellation apply

    apply stores the state of your cluster's cloud resources in a constellation-terraform directory in your workspace.

    -

    Finally, configure kubectl for your cluster:

    -
    export KUBECONFIG="$PWD/constellation-admin.conf"
    -

    🏁 That's it. You've successfully created a Constellation cluster.

    -

    Troubleshooting​

    -

    In case apply fails, the CLI collects logs from the bootstrapping instance and stores them inside constellation-cluster.log.

    Expose a service

    -

    Constellation integrates the native load balancers of each CSP. Therefore, to expose a service simply create a service of type LoadBalancer.

    -

    Internet-facing LB service on AWS​

    -

    To expose your application service externally you might want to use a Kubernetes Service of type LoadBalancer. On AWS, load-balancing is achieved through the AWS Load Balancer Controller as in the managed EKS.

    -

    Since recent versions, the controller deploy an internal LB by default requiring to set an annotation service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing to have an internet-facing LB. For more details, see the official docs.

    -

    For general information on LB with AWS see Network load balancing on Amazon EKS.

    -
    caution

    Before terminating the cluster, all LB backed services should be deleted, so that the controller can cleanup the related resources.

    -

    Ingress on AWS​

    -

    The AWS Load Balancer Controller also provisions Ingress resources of class alb. -AWS Application Load Balancers (ALBs) can be configured with a target-type. -The target type ip requires using the EKS container network solution, which makes it incompatible with Constellation. -If a service can be exposed on a NodePort, the target type instance can be used.

    Version: 2.24

    Recover your cluster

    -

    Recovery of a Constellation cluster means getting it back into a healthy state after too many concurrent node failures in the control plane. -Reasons for an unhealthy cluster can vary from a power outage, or planned reboot, to migration of nodes and regions. -Recovery events are rare, because Constellation is built for high availability and automatically and securely replaces failed nodes. When a node is replaced, Constellation's control plane first verifies the new node before it sends the node the cryptographic keys required to decrypt its state disk.

    -

    Constellation provides a recovery mechanism for cases where the control plane has failed and is unable to replace nodes. -The constellation recover command securely connects to all nodes in need of recovery using attested TLS and provides them with the keys to decrypt their state disks and continue booting.

    -

    Identify unhealthy clusters​

    -

    The first step to recovery is identifying when a cluster becomes unhealthy. -Usually, this can be first observed when the Kubernetes API server becomes unresponsive.

    -

    You can check the health status of the nodes via the cloud service provider (CSP). -Constellation provides logging information on the boot process and status via serial console output. -In the following, you'll find detailed descriptions for identifying clusters stuck in recovery for each CSP.

    -

    First, open the AWS console to view all Auto Scaling Groups (ASGs) in the region of your cluster. Select the ASG of the control plane <cluster-name>-<UID>-control-plane and check that enough members are in a Running state.

    Second, check the boot logs of these Instances. In the ASG's Instance management view, select each desired instance. In the upper right corner, select Action > Monitor and troubleshoot > Get system log.

    In the serial console output, search for Waiting for decryption key. -Similar output to the following means your node was restarted and needs to decrypt the state disk:

    {"level":"INFO","ts":"2022-09-08T10:21:53Z","caller":"cmd/main.go:55","msg":"Starting disk-mapper","version":"2.0.0","cloudProvider":"gcp"}

    {"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"recoveryServer","caller":"recoveryserver/server.go:59","msg":"Starting RecoveryServer"}

    The node will then try to connect to the JoinService and obtain the decryption key. -If this fails due to an unhealthy control plane, you will see log messages similar to the following:

    {"level":"INFO","ts":"2022-09-08T10:21:53Z","logger":"rejoinClient","caller":"rejoinclient/client.go:77","msg":"Received list with JoinService endpoints","endpoints":["192.168.178.4:30090","192.168.178.2:30090"]}

    -

    Constellation has first-class support for reproducible builds. -Reproducing the released artifacts is an alternative to signature verification that doesn't require trusting Edgeless Systems' release process. -The following sections describe how to rebuild an artifact and how Constellation ensures that the rebuild reproduces the artifacts bit-by-bit.

    -

    Build environment prerequisites​

    -

    The build systems used by Constellation - Bazel and Nix - are designed for deterministic, reproducible builds. -These two dependencies should be the only prerequisites for a successful build. -However, it can't be ruled out completely that peculiarities of the host affect the build result. -Thus, we recommend the following host setup for best results:

    -
      -
    1. A Linux operating system not older than v5.4.
      2. -
    2. The GNU C library not older than v2.31 (avoid musl).
      3. -
    3. GNU coreutils not older than v8.30 (avoid busybox).
      4. -
    4. An ext4 filesystem for building.
      5. -
    5. AppArmor turned off.
      6. -
    -

    This is given, for example, on an Ubuntu 22.04 system, which is also used for reproducibility tests.

    -
    note

    To avoid any backwards-compatibility issues, the host software versions should also not be much newer than the Constellation release.

    -

    Run the build​

    -

    The following instructions outline qualitatively how to reproduce a build. -Constellation implements these instructions in the Reproducible Builds workflow, which continuously tests for reproducibility. -The workflow is a good place to look up specific version numbers and build steps.

    -
      -
    1. -

      Check out the Constellation repository at the tag corresponding to the release.

      -
      git clone https://github.com/edgelesssys/constellation.git

    -

    Constellation includes a transparent client-side encryption proxy for AWS S3 and compatible stores. -s3proxy encrypts objects before sending them to S3 and automatically decrypts them on retrieval, without requiring changes to your application. -With s3proxy, you can use S3 for storage in a confidential way without having to trust the storage provider.

    -

    Limitations​

    -

    Currently, s3proxy has the following limitations:

    -
      -
    • Only PutObject and GetObject requests are encrypted/decrypted by s3proxy. -By default, s3proxy will block requests that may expose unencrypted data to S3 (e.g. UploadPart). -The allow-multipart flag disables request blocking for evaluation purposes.
      • -
    • Using the Range header on GetObject is currently not supported and will result in an error.
      • -
    -

    These limitations will be removed with future iterations of s3proxy. -If you want to use s3proxy but these limitations stop you from doing so, consider opening an issue.

    -

    Deployment​

    -

    You can add the s3proxy to your Constellation cluster as follows:

    -
      -
    1. Add the Edgeless Systems chart repository: -
      helm repo add edgeless https://helm.edgeless.systems/stable
      helm repo update
      -
      2. -
    2. Set ACCESS_KEY and ACCESS_SECRET to valid credentials you want s3proxy to use to interact with S3.
      3. -
    3. Deploy s3proxy: -
      helm install s3proxy edgeless/s3proxy --set awsAccessKeyID="$ACCESS_KEY" --set awsSecretAccessKey="$ACCESS_SECRET"
      -
      4. -
    -

    If you want to run a demo application, check out the Filestash with s3proxy example.

    -

    Technical details​

    -

    Encryption​

    -

    s3proxy relies on Google's Tink Cryptographic Library to implement cryptographic operations securely. -The used cryptographic primitives are NIST SP 800 38f for key wrapping and AES-GCM with 256 bit keys for data encryption.

    -

    s3proxy uses envelope encryption to encrypt objects. -This means s3proxy uses a key encryption key (KEK) issued by the KeyService to encrypt data encryption keys (DEKs). -Each S3 object is encrypted with its own DEK. -The encrypted DEK is then saved as metadata of the encrypted object. -This enables key rotation of the KEK without re-encrypting the data in S3. -The approach also allows access to objects from different locations, as long as each location has access to the KEK.

    -

    Traffic interception​

    -

    To use s3proxy, you have to redirect your outbound S3 traffic to s3proxy. -This can either be done by modifying your client application or by changing the deployment of your application.

    -

    The necessary deployment modifications are to add DNS redirection and a trusted TLS certificate to the client's trust store. -DNS redirection can be defined for each pod, allowing you to use s3proxy for one application without changing other applications in the same cluster. -Adding a trusted TLS certificate is necessary as clients communicate with s3proxy via HTTPS. -To have your client application trust s3proxy's TLS certificate, the certificate has to be added to the client's certificate trust store. -The Filestash with s3proxy example shows how to do this.

    Verify and download SBOMs​

    -

    The following sections detail how to work with each type of artifact to verify and extract the SBOM.

    -

    Constellation CLI​

    -

    The SBOM for Constellation CLI is made available on the GitHub release page. The SBOM (constellation.spdx.sbom) and corresponding signature (constellation.spdx.sbom.sig) are valid for each Constellation CLI for a given version, regardless of architecture and operating system.

    -

    Container Images​

    -

    SBOMs for container images are attached to the image using Cosign and uploaded to the same registry.

    -

    As a consumer, use cosign to download and verify the SBOM:

    -
    # Verify and download the attestation statement
    cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.att.json
    # Extract SBOM from attestation statement
    jq -r .payload verification-service.att.json | base64 -d > verification-service.cyclonedx.sbom
    -

    A successful verification should result in similar output:

    -
    $ cosign verify-attestation ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --type 'https://cyclonedx.org/bom' --key cosign.pub --output-file verification-service.sbom

    Verification for ghcr.io/edgelesssys/constellation/verification-service@v2.2.0 --
    The following checks were performed on each of these signatures:
      - The cosign claims were validated
      - The signatures were verified against the specified public key
    $ jq -r .payload verification-service.sbom | base64 -d > verification-service.cyclonedx.sbom
    -
    note

    This example considers only the verification-service. The same approach works for all containers in the Constellation container registry.

    Vulnerability scanning​

    -

    You can use a plethora of tools to consume SBOMs. This section provides suggestions for tools that are popular and known to produce reliable results, but any tool that consumes SPDX or CycloneDX files should work.

    -

    Syft is able to convert between the two formats in case you require a specific type.

    -

    Grype​

    -

    Grype is a CLI tool that lends itself well for integration into CI/CD systems or local developer machines. It's also able to consume the signed attestation statement directly and does the verification in one go.

    -
    grype att:verification-service.sbom --key cosign.pub --add-cpes-if-none -q
    -

    Dependency Track​

    -

    Dependency Track is one of the oldest and most mature solutions when it comes to managing software inventory and vulnerabilities. Once imported, it continuously scans SBOMs for new vulnerabilities. It supports the CycloneDX format and provides direct guidance on how to comply with U.S. Executive Order 14028.

    Version: 2.24

    Scale your cluster

    -

    Constellation provides all features of a Kubernetes cluster including scaling and autoscaling.

    -

    Worker node scaling​

    -

    Autoscaling​

    -

    Constellation comes with autoscaling disabled by default. To enable autoscaling, find the scaling group of -worker nodes:

    -
    kubectl get scalinggroups -o json | yq '.items | .[] | select(.spec.role == "Worker") | [{"name": .metadata.name, "nodeGoupName": .spec.nodeGroupName}]'
    -

    This will output a list of scaling groups with the corresponding cloud provider name (name) and the cloud provider agnostic name of the node group (nodeGroupName).

    -

    Then, patch the autoscaling field of the scaling group resource with the desired name to true:

    -
    # Replace <name> with the name of the scaling group you want to enable autoscaling for
    worker_group=<name>
    kubectl patch scalinggroups $worker_group --patch '{"spec":{"autoscaling": true}}' --type='merge'
    kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
    -

    The cluster autoscaler now automatically provisions additional worker nodes so that all pods have a place to run. -You can configure the minimum and maximum number of worker nodes in the scaling group by patching the min or -max fields of the scaling group resource:

    -
    kubectl patch scalinggroups $worker_group --patch '{"spec":{"max": 5}}' --type='merge'
    kubectl get scalinggroup $worker_group -o jsonpath='{.spec}' | yq -P
    -

    The cluster autoscaler will now never provision more than 5 worker nodes.

    -

    If you want to see the autoscaling in action, try to add a deployment with a lot of replicas, like the -following Nginx deployment. The number of replicas needed to trigger the autoscaling depends on the size of -and count of your worker nodes. Wait for the rollout of the deployment to finish and compare the number of -worker nodes before and after the deployment:

    -
    kubectl create deployment nginx --image=nginx --replicas 150
    kubectl -n kube-system get nodes
    kubectl rollout status deployment nginx
    kubectl -n kube-system get nodes
    -

    Manual scaling​

    -

    Alternatively, you can manually scale your cluster up or down:

    -
      -
    1. Go to Auto Scaling Groups and select the worker ASG to scale up.
      2. -
    2. Click Edit
      3. -
    3. Set the new (increased) Desired capacity and Update.
      4. -
    -

    Control-plane node scaling​

    -

    Control-plane nodes can only be scaled manually and only scaled up!

    -

    To increase the number of control-plane nodes, follow these steps:

    -
      -
    1. Go to Auto Scaling Groups and select the control-plane ASG to scale up.
      2. -
    2. Click Edit
      3. -
    3. Set the new (increased) Desired capacity and Update.
      4. -
    -

    If you scale down the number of control-planes nodes, the removed nodes won't be able to exit the etcd cluster correctly. This will endanger the quorum that's required to run a stable Kubernetes control plane.

    Version: 2.24

    Use persistent storage

    -

    Persistent storage in Kubernetes requires cloud-specific configuration. -For abstraction of container storage, Kubernetes offers volumes, -allowing users to mount storage solutions directly into containers. -The Container Storage Interface (CSI) is the standard interface for exposing arbitrary block and file storage systems into containers in Kubernetes. -Cloud service providers (CSPs) offer their own CSI-based solutions for cloud storage.

    -

    Confidential storage​

    -

    Most cloud storage solutions support encryption, such as GCE Persistent Disks (PD). -Constellation supports the available CSI-based storage options for Kubernetes engines in AWS, Azure, GCP, and STACKIT. -However, their encryption takes place in the storage backend and is managed by the CSP. -Thus, using the default CSI drivers for these storage types means trusting the CSP with your persistent data.

    -

    To address this, Constellation provides CSI drivers for AWS EBS, Azure Disk, GCE PD, and OpenStack Cinder, offering encryption on the node level. They enable transparent encryption for persistent volumes without needing to trust the cloud backend. Plaintext data never leaves the confidential VM context, offering you confidential storage.

    -

    For more details see encrypted persistent storage.

    -

    CSI drivers​

    -

    Constellation supports the following drivers, which offer node-level encryption and optional integrity protection.

    -

    Constellation CSI driver for AWS Elastic Block Store -Mount Elastic Block Store storage volumes into your Constellation cluster. -Follow the instructions on how to install the Constellation CSI driver or check out the repository for more information.

    -

    Note that in case the options above aren't a suitable solution for you, Constellation is compatible with all other CSI-based storage options. For example, you can use AWS EFS, Azure Files, or GCP Filestore with Constellation out of the box. Constellation is just not providing transparent encryption on the node level for these storage types yet.

    -

    Installation​

    -

    The Constellation CLI automatically installs Constellation's CSI driver for the selected CSP in your cluster. -If you don't need a CSI driver or wish to deploy your own, you can disable the automatic installation by setting deployCSIDriver to false in your Constellation config file.

    For more information on encryption algorithms and key sizes, refer to cryptographic algorithms.

    info

    The default storage class is set to encrypted-rwo for performance reasons. -If you want integrity-protected storage, set the storageClassName parameter of your persistent volume claim to integrity-encrypted-rwo.

    Alternatively, you can create your own storage class with integrity protection enabled by adding csi.storage.k8s.io/fstype: ext4-integrity to the class parameters. -Or use another filesystem by specifying another file system type with the suffix -integrity, e.g., csi.storage.k8s.io/fstype: xfs-integrity.

    Note that volume expansion isn't supported for integrity-protected disks.

    -
      -
    1. -

      Create a persistent volume

      -

      A persistent volume claim is a request for storage with certain properties. -It can refer to a storage class. -The following creates a persistent volume claim, requesting 20 GB of storage via the encrypted-rwo storage class:

      -
      cat <<EOF | kubectl apply -f -
      kind: PersistentVolumeClaim
      apiVersion: v1

      EOF
      -
      3. -
    -

    Change the default storage class​

    -

    The default storage class is responsible for all persistent volume claims that don't explicitly request storageClassName. -Constellation creates a storage class with encryption enabled and sets this as the default class. -In case you wish to change it, follow the steps below:

    -
      -
    1. -

      List the storage classes in your cluster:

      -
      kubectl get storageclass
      -

      The output is similar to this:

      -

      -

      The default storage class is marked by (default).

      -
      2. -
    2. -

      Mark old default storage class as non default

      -

      If you previously used another storage class as the default, you will have to remove that annotation:

      -
      kubectl patch storageclass encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"false"}}}'
      -
      3. -
    3. -

      Mark new class as the default

      -
      kubectl patch storageclass integrity-encrypted-rwo -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
      -
      4. -
    4. -

      Verify that your chosen storage class is default:

    You can terminate your cluster using the CLI. For this, you need the Terraform state directory named constellation-terraform in the current directory.

    -
    danger

    All ephemeral storage and state of your cluster will be lost. Make sure any data is safely stored in persistent storage. Constellation can recreate your cluster and the associated encryption keys, but won't backup your application data automatically.

    -

    Terminate the cluster by running:

    constellation terminate

    Or without confirmation (e.g., for automation purposes):

    constellation terminate --yes

    This deletes all resources created by Constellation in your cloud environment. -All local files created by the apply command are deleted as well, except for constellation-mastersecret.json and the configuration file.

    caution

    Termination can fail if additional resources have been created that depend on the ones managed by Constellation. In this case, you need to delete these additional -resources manually. Just run the terminate command again afterward to continue the termination process of the cluster.

    Use the Terraform provider

    -

    The Constellation Terraform provider allows to manage the full lifecycle of a Constellation cluster (namely creation, upgrades, and deletion) via Terraform. -The provider is available through the Terraform registry and is released in lock-step with Constellation releases.

    -

    Prerequisites​

    -
      -
    • a Linux / Mac operating system (ARM64/AMD64)
      • -
    • a Terraform installation of version v1.4.4 or above
      • -
    -

    Quick setup​

    -

    This example shows how to set up a Constellation cluster with the reference IAM and infrastructure setup. This setup is also used when creating a Constellation cluster through the Constellation CLI. You can either consume the IAM / infrastructure modules through a remote source (recommended) or local files. The latter requires downloading the infrastructure and IAM modules for the corresponding CSP from terraform-modules.zip on the Constellation release page and placing them in the Terraform workspace directory.

    -
      -
    1. Create a directory (workspace) for your Constellation cluster.
      2. -
    -
    mkdir constellation-workspace
    cd constellation-workspace
    -
      -
    1. Use one of the example configurations for using the Constellation Terraform provider or create a main.tf file and fill it with the resources you want to create. The Constellation Terraform provider documentation offers thorough documentation on the resources and their attributes.
      2. -
    2. Initialize and apply the Terraform configuration.
      3. -
    -

    Initialize the providers and apply the configuration.

    terraform init
    terraform apply

    Optionally, you can prefix the terraform apply command with TF_LOG=INFO to collect Terraform logs while applying the configuration. This may provide helpful output in debugging scenarios.

    -
      -
    1. Connect to the cluster.
      2. -
    -
    terraform output -raw kubeconfig > constellation-admin.conf
    export KUBECONFIG=$(realpath constellation-admin.conf)
    -

    Bringing your own infrastructure​

    -

    Instead of using the example infrastructure used in the quick setup, you can also provide your own infrastructure. -If you need a starting point for a custom infrastructure setup, you can download the infrastructure / IAM Terraform modules for the respective CSP from the Constellation GitHub releases. You can modify and extend the modules per your requirements, while keeping the basic functionality intact. -The module contains:

    -
      -
    • {csp}: cloud resources the cluster runs on
      • -
    • iam/{csp}: IAM resources used within the cluster
      • -
    -

    When upgrading your cluster, make sure to check the Constellation release notes for potential breaking changes in the reference infrastructure / IAM modules that need to be considered.

    -

    Cluster upgrades​

    -
    tip

    Also see the general documentation on cluster upgrades.

    -

    The steps for applying the upgrade are as follows:

    -
      -
    1. Update the version constraint of the Constellation Terraform provider in the required_providers block in your Terraform configuration.
      2. -
    2. If you explicitly set any of the version attributes of the provider's resources and data sources (e.g. image_version or constellation_microservice_version), make sure to update them too. Refer to Constellation's version support policy for more information on how each Constellation version and its dependencies are supported.
      3. -
    3. Update the IAM / infrastructure configuration. - -
      4. -
    4. Upgrade the Terraform module and provider dependencies and apply the targeted configuration.

    Troubleshooting

    -

    This section aids you in finding problems when working with Constellation.

    -

    Common issues​

    -

    Issues with creating new clusters​

    -

    When you create a new cluster, you should always use the latest release. -If something doesn't work, check out the known issues.

    -

    Azure: Resource Providers can't be registered​

    -

    On Azure, you may receive the following error when running apply or terminate with limited IAM permissions:

    -
    Error: Error ensuring Resource Providers are registered.

    Terraform automatically attempts to register the Resource Providers it supports to
    ensure it's able to provision resources.

    If you don't have permission to register Resource Providers you may wish to use the
    "skip_provider_registration" flag in the Provider block to disable this functionality.

    [...]
    -

    To continue, please ensure that the required resource providers have been registered in your subscription by your administrator.

    -

    Afterward, set ARM_SKIP_PROVIDER_REGISTRATION=true as an environment variable and either run apply or terminate again. -For example:

    -
    ARM_SKIP_PROVIDER_REGISTRATION=true constellation apply
    -

    Or alternatively, for terminate:

    -
    ARM_SKIP_PROVIDER_REGISTRATION=true constellation terminate
    -

    Azure: Can't update attestation policy​

    -

    On Azure, you may receive the following error when running apply from within an Azure environment, e.g., an Azure VM:

    -
    An error occurred: patching policies: updating attestation policy: unexpected status code: 403 Forbidden
    -

    The problem occurs because the Azure SDK we use internally attempts to authenticate towards the Azure API with the managed identity of your current environment instead of the Azure CLI token.

    -

    We decided not to deviate from this behavior and comply with the ordering of credentials.

    -

    A solution is to add the required permissions to the managed identity of your environment. For example, the managed identity of your Azure VM, instead of the account that you've authenticated with in the Azure CLI.

    -

    If your setup requires a change in the ordering of credentials, please open an issue and explain your desired behavior.

    -

    Nodes fail to join with error untrusted measurement value​

    -

    This error indicates that a node's attestation statement contains measurements that don't match the trusted values expected by the JoinService. -This may for example happen if the cloud provider updates the VM's firmware such that it influences the runtime measurements in an unforeseen way. -A failed upgrade due to an erroneous attestation config can also cause this error. -You can change the expected measurements to resolve the failure.

    -
    caution

    Attestation and trusted measurements are crucial for the security of your cluster. -Be extra careful when manually changing these settings. -When in doubt, check if the encountered issue is known or contact support.

    -
    tip

    During an upgrade with modified attestation config, a backup of the current configuration is stored in the join-config config map in the kube-system namespace under the attestationConfig_backup key. To restore the old attestation config after a failed upgrade, replace the value of attestationConfig with the value from attestationConfig_backup:

    kubectl patch configmaps -n kube-system join-config -p "{\"data\":{\"attestationConfig\":\"$(kubectl get configmaps -n kube-system join-config -o "jsonpath={.data.attestationConfig_backup}")\"}}"
    -

    You can use the apply command to change measurements of a running cluster:

    -
      -
    1. Modify the measurements key in your local constellation-conf.yaml to the expected values.
      2. -
    2. Run constellation apply.
      3. -
    -

    Keep in mind that running apply also applies any version changes from your config to the cluster.

    -

    You can run these commands to learn about the versions currently configured in the cluster:

    -
      -
    • Kubernetes API server version: kubectl get nodeversion constellation-version -o json -n kube-system | jq .spec.kubernetesClusterVersion
      • -
    • image version: kubectl get nodeversion constellation-version -o json -n kube-system | jq .spec.imageVersion
      • -
    • microservices versions: helm list --filter 'constellation-services' -n kube-system
      • -
    -

    Upgrading Kubernetes resources fails​

    -

    Constellation manages its Kubernetes resources using Helm. -When applying an upgrade, the charts that are about to be installed, and a values override file overrides.yaml, -are saved to disk in your current workspace under constellation-upgrade/upgrade-<timestamp>/helm-charts/. -If upgrading the charts using the Constellation CLI fails, you can review these charts and try to manually apply the upgrade.

    -
    caution

    Changing and manually applying the charts may destroy cluster resources and can lead to broken Constellation deployments. -Proceed with caution and when in doubt, -check if the encountered issue is known or contact support.

    -

    Diagnosing issues​

    -

    Logs​

    -

    To get started on diagnosing issues with Constellation, it's often helpful to collect logs from nodes, pods, or other resources in the cluster. Most logs are available through Kubernetes' standard -logging interfaces.

    -

    To debug issues occurring at boot time of the nodes, you can use the serial console interface of the CSP while the machine boots to get a read-only view of the boot logs.

    -

    Apart from that, Constellation also offers further observability integrations.

    -

    Node shell access​

    -

    Debugging via a shell on a node is directly supported by Kubernetes.

    -
      -
    1. -

      Figure out which node to connect to:

      -
      kubectl get nodes
      # or to see more information, such as IPs:
      kubectl get nodes -o wide
      -
      2. -
    2. -

      Connect to the node:

      -
      kubectl debug node/constell-worker-xksa0-000000 -it --image=busybox
      -

      You will be presented with a prompt.

      -

      The nodes file system is mounted at /host.

      -
      3. -
    3. -

      Once finished, clean up the debug pod:

      -
      kubectl delete pod node-debugger-constell-worker-xksa0-000000-bjthj
      -
      4. -
    -

    Emergency SSH access​

    -

    Emergency SSH access to nodes can be useful to diagnose issues or download important data even if the Kubernetes API isn't reachable anymore.

    -

      Enter the constellation-terraform directory in your Constellation workspace and enable emergency SSH access to the cluster:

      -
       cd constellation-terraform
       echo "emergency_ssh = true" >> ./terraform.tfvars
       terraform apply
      -

      Sign an existing SSH key with your master secret:

      -
      cd ../ # go back to your Constellation workspace
      constellation ssh --key your_public_key.pub
      -

      A certificate is written to constellation_cert.pub.

      -

      The certificate is valid for 24 hours and enables you to access your Constellation nodes using -certificate based authentication.

      -
      3. -
    3. -

      Now you can connect to any Constellation node using your certificate and your private key.

      -
      ssh -o CertificateFile=constellation_cert.pub -o UserKnownHostsFile=./known_hosts -i <your private key> root@<ip of constellation node>
      -

      Normally, you don't have access to the Constellation nodes since they reside in a private network. -To access those nodes anyways, you can use your Constellation load balancer as a proxy jump host. -For this, use something along the following SSH client configuration:

      -
      Host <LB public IP>
        ProxyJump none

      Host *
        IdentityFile <your private key>
        PreferredAuthentications publickey
        CertificateFile=constellation_cert.pub
        UserKnownHostsFile=./known_hosts
        User root
        ProxyJump <LB public IP>
      -

      With this configuration you can connect to a Constellation node using ssh -F <this config> <private node IP>. -You can obtain the private node IP and the public IP of the load balancer using your CSP's web UI. Note that if -you use the load balancers domain name, ssh host certificate verification doesn't work, so using the public IP is recommended.

    Version: 2.24

    Use Azure trusted launch VMs

    -

    Constellation also supports trusted launch VMs on Microsoft Azure. Trusted launch VMs don't offer the same level of security as Confidential VMs, but are available in more regions and in larger quantities. The main difference between trusted launch VMs and normal VMs is that the former offer vTPM-based remote attestation. When used with trusted launch VMs, Constellation relies on vTPM-based remote attestation to verify nodes.

    -
    caution

    Trusted launch VMs don't provide runtime encryption and don't keep the cloud service provider (CSP) out of your trusted computing base.

    -

    Constellation supports trusted launch VMs with instance types Standard_D*_v4 and Standard_E*_v4. Run constellation config instance-types for a list of all supported instance types.

    -

    VM images​

    -

    Azure currently doesn't support community galleries for trusted launch VMs. Thus, you need to manually import the Constellation node image into your cloud subscription.

    -

    The latest image is available at https://cdn.confidential.cloud/constellation/images/azure/trusted-launch/v2.2.0/constellation.img. Simply adjust the version number to download a newer version.

    -

    After you've downloaded the image, create a resource group constellation-images in your Azure subscription and import the image. -You can use a script to do this:

    -
    wget https://raw.githubusercontent.com/edgelesssys/constellation/main/hack/importAzure.sh
    chmod +x importAzure.sh
    AZURE_IMAGE_VERSION=2.2.0 AZURE_RESOURCE_GROUP_NAME=constellation-images AZURE_IMAGE_FILE=./constellation.img ./importAzure.sh
    -

    The script creates the following resources:

    -
      -
    1. A new image gallery with the default name constellation-import
      2. -
    2. A new image definition with the default name constellation
      3. -
    3. The actual image with the provided version. In this case 2.2.0
      4. -
    -

    Once the import is completed, use the ID of the image version in your constellation-conf.yaml for the image field. Set confidentialVM to false.

    -

    Fetch the image measurements:

    -
    IMAGE_VERSION=2.2.0
    URL=https://public-edgeless-constellation.s3.us-east-2.amazonaws.com//communitygalleries/constellationcvm-b3782fa0-0df7-4f2f-963e-fc7fc42663df/images/constellation/versions/$IMAGE_VERSION/measurements.yaml
    constellation config fetch-measurements -u$URL -s$URL.sig
    -
    info

    The constellation apply command will issue a warning because manually imported images aren't recognized as production grade images:

    Configured image doesn't look like a released production image. Double check image before deploying to production.

    Please ignore this warning.

    Version: 2.24

    Upgrade your cluster

    -

    Constellation provides an easy way to upgrade all components of your cluster, without disrupting its availability. -Specifically, you can upgrade the Kubernetes version, the nodes' image, and the Constellation microservices. -You configure the desired versions in your local Constellation configuration and trigger upgrades with the apply command. -To learn about available versions you use the upgrade check command. -Which versions are available depends on the CLI version you are using.

    -

    Update the CLI​

    -

    Each CLI comes with a set of supported microservice and Kubernetes versions. -Most importantly, a given CLI version can only upgrade a cluster of the previous minor version, but not older ones. -This means that you have to upgrade your CLI and cluster one minor version at a time.

    -

    For example, if you are currently on CLI version v2.6 and the latest version is v2.8, you should

    -
      -
    • upgrade the CLI to v2.7,
      • -
    • upgrade the cluster to v2.7,
      • -
    • and only then continue upgrading the CLI (and the cluster) to v2.8 after.
      • -
    -

    Also note that if your current Kubernetes version isn't supported by the next CLI version, use your current CLI to upgrade to a newer Kubernetes version first.

    -

    To learn which Kubernetes versions are supported by a particular CLI, run constellation config kubernetes-versions.

    -

    Migrate the configuration​

    -

    The Constellation configuration file is located in the file constellation-conf.yaml in your workspace. -Refer to the migration reference to check if you need to update fields in your configuration file. -Use constellation config migrate to automatically update an old config file to a new format.

    -

    Check for upgrades​

    -

    To learn which versions the current CLI can upgrade to and what's installed in your cluster, run:

    -
    # Show possible upgrades
    constellation upgrade check

    # Show possible upgrades and write them to config file
    constellation upgrade check --update-config
    -

    You can either enter the reported target versions into your config manually or run the above command with the --update-config flag. -When using this flag, the kubernetesVersion, image, microserviceVersion, and attestation fields are overwritten with the smallest available upgrade.

    -

    Apply the upgrade​

    -

    Once you updated your config with the desired versions, you can trigger the upgrade with this command:

    -
    constellation apply
    -

    Microservice upgrades will be finished within a few minutes, depending on the cluster size. -If you are interested, you can monitor pods restarting in the kube-system namespace with your tool of choice.

    -

    Image and Kubernetes upgrades take longer. -For each node in your cluster, a new node has to be created and joined. -The process usually takes up to ten minutes per node.

    -

    When applying an upgrade, the Helm charts for the upgrade as well as backup files of Constellation-managed Custom Resource Definitions, Custom Resources, and Terraform state are created. -You can use the Terraform state backup to restore previous resources in case an upgrade misconfigured or erroneously deleted a resource. -You can use the Custom Resource (Definition) backup files to restore Custom Resources and Definitions manually (e.g., via kubectl apply) if the automatic migration of those resources fails. -You can use the Helm charts to manually apply upgrades to the Kubernetes resources, should an upgrade fail.

    -
    note

    For advanced users: the upgrade consists of several phases that can be individually skipped through the --skip-phases flag. -The phases are infrastracture for the cloud resource management through Terraform, helm for the chart management of the microservices, image for OS image upgrades, and k8s for Kubernetes version upgrades.

    -

    Check the status​

    -

    Upgrades are asynchronous operations. -After you run apply, it will take a while until the upgrade has completed. -To understand if an upgrade is finished, you can run:

    -
    constellation status
    -

    This command displays the following information:

    -
      -
    • The installed services and their versions
      • -
    • The image and Kubernetes version the cluster is expecting on each node
      • -
    • How many nodes are up to date
      • -
    -

    Here's an example output:

    -
    Target versions:
        Image: v2.6.0
        Kubernetes: v1.25.8
    Service versions:
        Cilium: v1.12.1
        cert-manager: v1.10.0
        constellation-operators: v2.6.0
        constellation-services: v2.6.0
    Cluster status: Some node versions are out of date
        Image: 23/25
        Kubernetes: 25/25
    -

    This output indicates that the cluster is running Kubernetes version 1.25.8, and all nodes have the appropriate binaries installed. -23 out of 25 nodes have already upgraded to the targeted image version of 2.6.0, while two are still in progress.

    -

    Apply further upgrades​

    -

    After the upgrade is finished, you can run constellation upgrade check again to see if there are more upgrades available. If so, repeat the process.

    Edgeless Systems uses sigstore and SLSA to ensure supply-chain security for the Constellation CLI and node images ("artifacts"). sigstore consists of three components: Cosign, Rekor, and Fulcio. Edgeless Systems uses Cosign to sign artifacts. All signatures are uploaded to the public Rekor transparency log, which resides at https://rekor.sigstore.dev.

    -
    note

    The public key for Edgeless Systems' long-term code-signing key is:

    -----BEGIN PUBLIC KEY-----
    MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEf8F1hpmwE+YCFXzjGtaQcrL6XZVT
    JmEe5iSLvG1SyQSAew7WdMKF6o9t8e2TFuCkzlOhhlws2OHWbiFZnFWCFw==
    -----END PUBLIC KEY-----

    The public key is also available for download at https://edgeless.systems/es.pub and in the Twitter profile @EdgelessSystems.

    -

    The Rekor transparency log is a public append-only ledger that verifies and records signatures and associated metadata. The Rekor transparency log enables everyone to observe the sequence of (software) signatures issued by Edgeless Systems and many other parties. The transparency log allows for the public identification of dubious or malicious signatures.

    -

    You should always ensure that (1) your CLI executable was signed with the private key corresponding to the above public key and that (2) there is a corresponding entry in the Rekor transparency log. Both can be done as described in the following.

    -
    info

    You don't need to verify the Constellation node images. This is done automatically by your CLI and the rest of Constellation.

    -

    Verify the signature​

    -
    info

    This guide assumes Linux on an amd64 processor. The exact steps for other platforms differ slightly.

    -

    First, install the Cosign CLI. Next, download and verify the signature that accompanies your CLI executable, for example:

    -
    $ cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

    Verified OK
    -

    The above performs an offline verification of the provided public key, signature, and executable. To also verify that a corresponding entry exists in the public Rekor transparency log, add the variable COSIGN_EXPERIMENTAL=1:

    -
    $ COSIGN_EXPERIMENTAL=1 cosign verify-blob --key https://edgeless.systems/es.pub --signature constellation-linux-amd64.sig constellation-linux-amd64

    tlog entry verified with uuid: afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13 index: 3477047
    Verified OK
    -

    🏁 You now know that your CLI executable was officially released and signed by Edgeless Systems.

    -

    Optional: Manually inspect the transparency log​

    -

    To further inspect the public Rekor transparency log, install the Rekor CLI. A search for the CLI executable should give a single UUID. (Note that this UUID contains the UUID from the previous cosign command.)

    -
    $ rekor-cli search --artifact constellation-linux-amd64

    Found matching entries (listed by UUID):
    362f8ecba72f4326afaba7f6635b3e058888692841848e5514357315be9528474b23f5dcccb82b13
    -

    With this UUID you can get the full entry from the transparency log:

    -
    rekor-cli search --public-key https://edgeless.systems/es.pub --pki-format x509
    -

    Edgeless Systems monitors this list to detect potential unauthorized use of its private key.

    -

    Verify the provenance​

    -

    Provenance attests that a software artifact was produced by a specific repository and build system invocation. For more information on provenance visit slsa.dev and learn about the adoption of SLSA for Constellation.

    -

    Just as checking its signature proves that the CLI hasn't been manipulated, checking the provenance proves that the artifact was produced by the expected build process and hasn't been tampered with.

    -

    To verify the provenance, first install the slsa-verifier. Then make sure you have the provenance file (constellation.intoto.jsonl) and Constellation CLI downloaded. Both are available on the GitHub release page.

    -
    info

    The same provenance file is valid for all Constellation CLI executables of a given version independent of the target platform.

    -

    Use the verifier to perform the check:

    -
    $ slsa-verifier verify-artifact constellation-linux-amd64 \
      --provenance-path constellation.intoto.jsonl \
      --source-uri github.com/edgelesssys/constellation

    -

    Constellation's attestation feature allows you, or a third party, to verify the integrity and confidentiality of your Constellation cluster.

    -

    Fetch measurements​

    -

    To verify the integrity of Constellation you need trusted measurements to verify against. For each node image released by Edgeless Systems, there are signed measurements, which you can download using the CLI:

    -
    constellation config fetch-measurements
    -

    This command performs the following steps:

    -
      -
    1. Download the signed measurements for the configured image. By default, this will use Edgeless Systems' public measurement registry.
      2. -
    2. Verify the signature of the measurements. This will use Edgeless Systems' public key.
      3. -
    3. Write measurements into configuration file.
      4. -
    -

    The configuration file then contains a list of measurements similar to the following:

    -

    -

    Each entry specifies the expected value of the Constellation node, and whether the measurement should be enforced (warnOnly: false), or only a warning should be logged (warnOnly: true). -By default, the subset of the available measurements that can be locally reproduced and verified is enforced.

    -

    During attestation, the validating side (CLI or join service) compares each measurement reported by the issuing side (first node or joining node) individually. -For mismatching measurements that have set warnOnly to true only a warning is emitted. -For mismatching measurements that have set warnOnly to false an error is emitted and attestation fails. -If attestation fails for a new node, it isn't permitted to join the cluster.

    -

    The verify command​

    -
    note

    The steps below are purely optional. They're automatically executed by constellation apply when you initialize your cluster. The constellation verify command mostly has an illustrative purpose.

    -

    The verify command obtains and verifies an attestation statement from a running Constellation cluster.

    -
    constellation verify [--cluster-id ...]
    -

    From the attestation statement, the command verifies the following properties:

    -
      -
    • The cluster is using the correct Confidential VM (CVM) type.
      • -
    • Inside the CVMs, the correct node images are running. The node images are identified through the measurements obtained in the previous step.
      • -
    • The unique ID of the cluster matches the one from your constellation-state.yaml file or passed in via --cluster-id.
      • -
    -

    Once the above properties are verified, you know that you are talking to the right Constellation cluster and it's in a good and trustworthy shape.

    -

    Custom arguments​

    -

    The verify command also allows you to verify any Constellation deployment that you have network access to. For this you need the following:

    -
      -
    • The IP address of a running Constellation cluster's VerificationService. The VerificationService is exposed via a NodePort service using the external IP address of your cluster. Run kubectl get nodes -o wide and look for EXTERNAL-IP.
      • -
    • The cluster's clusterID. See cluster identity for more details.
      • -
    • A constellation-conf.yaml file with the expected measurements of the cluster in your working directory.
      • -
    -
