Constellation is the first Confidential Kubernetes. Constellation shields entire Kubernetes clusters from the (cloud) infrastructure using confidential computing.

KubernetesVersion sent by the init command now controls all downloaded binaries, if they depend on the k8s version. * Move all download links into /internal/versions. * Unify files in /internal/versions package * Move image download links into VersionConfigs and thus make them dependant on the k8s version, where the image version is specific to the k8s version. * Don't specify patch version in k8sVersion |

Constellation
This is the main repository of Constellation.
Core components:
- access_manager: Contains the access-manager pod used to persist SSH users based on a K8s ConfigMap
- cli: The CLI is used to manage a Constellation cluster
- bootstrapper: The bootstrapper is a node agent whose most important task is to bootstrap a node
- image: Build files for the Constellation disk image
- kms: Constellation's key management client and server
- mount: Package used by CSI plugins to create and mount encrypted block devices
- state: Contains the disk-mapper that maps the encrypted node data disk during boot
Development components:
- conformance: Kubernetes conformance tests
- debugd: Debug daemon and client
- hack: Development tools
- proto: Proto files generator
- terraform: Infrastructure management using terraform (instead of
constellation create/destroy)- libvirt: Deploy local cluster using terraform, libvirt and QEMU
- test: Integration test
Additional repositories:
- constellation-docs: End-user documentation
- constellation-coreos-assembler: Build environment for CoreOS images with changes for Constellation
- constellation-fedora-coreos-config: CoreOS build configuration with changes for Constellation
- edg-azuredisk-csi-driver: Azure CSI driver with encryption on node
- edg-gcp-compute-persistent-disk-csi-driver: GCP CSI driver with encryption on node
Build
Prerequisites:
-
Packages on Ubuntu:
sudo apt install build-essential cmake libssl-dev pkg-config libcryptsetup12 libcryptsetup-dev -
Packages on Fedora:
sudo dnf install @development-tools pkg-config cmake openssl-devel cryptsetup-libs cryptsetup-devel
mkdir build
cd build
cmake ..
make -j`nproc`
Testing
You can run all integration and unitttests like this:
ctest -j `nproc`
Cloud credentials
Using the CLI requires the user to make authorized API calls to the CSP API. See the docs for configuration.
Deploying a locally compiled bootstrapper binary
By default, constellation create ... will spawn cloud provider instances with a pre-baked bootstrapper binary.
For testing, you can use the constellation debug daemon (debugd) to upload your local bootstrapper binary to running instances and to obtain SSH access.
