# First steps with MiniConstellation
|
||||
|
||||
<!-- vale off -->
|
||||
With the `constellation mini` command, you can deploy and test Constellation locally without a cloud subscription. This mode is called MiniConstellation. Conceptually, MiniConstellation is similar to [MicroK8s](https://microk8s.io/), [K3s](https://k3s.io/), and [minikube](https://minikube.sigs.k8s.io/docs/).
|
||||
<!-- vale on -->
|
||||
|
||||
MiniConstellation uses virtualization to create a local cluster with one control-plane node and one worker node.
|
||||
|
||||
:::info
|
||||
|
||||
MiniConstellation **doesn't** require hardware with Confidential VM (CVM) support.
|
||||
For attestation, MiniConstellation currently uses the software-based vTPM provided by KVM/QEMU.
|
||||
|
||||
:::
|
||||
|
||||
:::note
|
||||
|
||||
Since MiniConstellation runs on your local system, cloud features such as load balancing,
|
||||
attaching persistent storage, or autoscaling aren't available.
|
||||
|
||||
:::
|
||||
|
||||
## Prerequisites
|
||||
|
||||
* A Linux OS with the following components installed
|
||||
* [Constellation CLI](./install.md#install-the-constellation-cli)
|
||||
* [KVM kernel module](https://www.linux-kvm.org/page/Main_Page)
|
||||
* [Docker](https://docs.docker.com/engine/install/)
|
||||
* [xsltproc](https://gitlab.gnome.org/GNOME/libxslt/-/wikis/home)
|
||||
* (Optional) [virsh](https://www.libvirt.org/manpages/virsh.html) to observe and access your nodes
|
||||
* Other system 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)
|
||||
|
||||
## Create your cluster
|
||||
|
||||
The following creates your MiniConstellation cluster (may take up to 10 minutes to complete):
|
||||
|
||||
```bash
|
||||
constellation mini up
|
||||
```
|
||||
|
||||
This will configure your current directory as the [workspace](../architecture/orchestration.md#workspaces) for this cluster.
|
||||
All `constellation` commands concerning this cluster need to be issued from this directory.
|
||||
|
||||
## Connect `kubectl`
|
||||
|
||||
Configure `kubectl` to connect to your local Constellation cluster:
|
||||
|
||||
```bash
|
||||
export KUBECONFIG="$PWD/constellation-admin.conf"
|
||||
```
|
||||
|
||||
Your cluster initially consists of a single control-plane node:
|
||||
|
||||
```shell-session
|
||||
$ kubectl get nodes
|
||||
NAME STATUS ROLES AGE VERSION
|
||||
control-plane-0 Ready control-plane 66s v1.24.6
|
||||
```
|
||||
|
||||
A worker node will request to join the cluster shortly. Before the new worker node is allowed to join the cluster, its state is verified using remote attestation by the [JoinService](../architecture/components.md#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:
|
||||
|
||||
```shell-session
|
||||
$ 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 the worker node has 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:
|
||||
|
||||
```shell-session
|
||||
$ 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](https://github.com/BuoyantIO/emojivoto)
|
||||
|
||||
```bash
|
||||
kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
|
||||
```
|
||||
|
||||
2. Expose the frontend service locally
|
||||
|
||||
```bash
|
||||
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:
|
||||
|
||||
```bash
|
||||
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
|
||||
|
||||
### VMs have no internet access
|
||||
|
||||
`iptables` rules may prevent your VMs from accessing the internet.
|
||||
Make sure your rules aren't dropping forwarded packages.
|
||||
|
||||
List your rules:
|
||||
|
||||
```bash
|
||||
sudo iptables -S
|
||||
```
|
||||
|
||||
The output may look similar to the following:
|
||||
|
||||
```shell-session
|
||||
-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:
|
||||
|
||||
```bash
|
||||
sudo iptables -P FORWARD ACCEPT
|
||||
```

## Create your cluster
|
||||
|
||||
Setting up your MiniConstellation cluster is as easy as running the following command:
|
||||
|
||||
```bash
|
||||
constellation mini up
|
||||
```
|
||||
|
||||
This will configure your current directory as the [workspace](../architecture/orchestration.md#workspaces) for this cluster.
|
||||
All `constellation` commands concerning this cluster need to be issued from this directory.
|
||||
|
||||
The command will create your cluster and initialize it. Depending on your system, this may take up to 10 minutes.
|
||||
The output should look like the following:
|
||||
|
||||
```shell-session
|
||||
$ constellation mini up
|
||||
Downloading image to ./constellation.qcow2
|
||||

|
||||
|
||||
You can now connect to your cluster by executing:
|
||||
export KUBECONFIG="$PWD/constellation-admin.conf"
|
||||
```
|
||||
|
||||
Configure `kubectl` to connect to your local Constellation cluster:
|
||||
|
||||
```bash
|
||||
export KUBECONFIG="$PWD/constellation-admin.conf"
|
||||
```
|
||||
|
||||
Your cluster initially consists of a single control-plane node:
|
||||
|
||||
```shell-session
|
||||
$ kubectl get nodes
|
||||
NAME STATUS ROLES AGE VERSION
|
||||
control-plane-0 Ready control-plane 66s v1.24.6

Once the worker node has joined your cluster, it may take a couple of minutes for all resources to be available.
|
||||
You can check on the state of your cluster by running the following:
|
||||
|
||||
```bash
|
||||
kubectl get nodes
|
||||
```
|
||||
|
||||
If your cluster is running as expected the output should look like the following:
|
||||
|
||||
```shell-session
|
||||
$ 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](https://github.com/BuoyantIO/emojivoto)
|
||||
|
||||
```bash
|
||||
kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
|
||||
```
|
||||
|
||||
2. Expose the frontend service locally
|
||||
|
||||
```bash
|
||||
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:
|
||||
|
||||
```bash
|
||||
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
|
||||
|
||||
### VMs have no internet access
|
||||
|
||||
`iptables` rules may prevent your VMs from accessing the internet.
|
||||
Make sure your rules aren't dropping forwarded packages.
|
||||
|
||||
List your rules:
|
||||
|
||||
```bash
|
||||
sudo iptables -S
|
||||
```
|
||||
|
||||
The output may look similar to the following:
|
||||
|
||||
```shell-session
|
||||
-P INPUT ACCEPT
|
||||
-P FORWARD DROP
|
||||
-P OUTPUT ACCEPT

|
||||
-N DOCKER-ISOLATION-STAGE-2
|
||||
-N DOCKER-USER
|
||||
```
|
||||
|

# First steps with MiniConstellation
|
||||
|
||||
<!-- vale off -->
|
||||
With the `constellation mini` command, you can deploy and test Constellation locally without a cloud subscription. This mode is called MiniConstellation. Conceptually, MiniConstellation is similar to [MicroK8s](https://microk8s.io/), [K3s](https://k3s.io/), and [minikube](https://minikube.sigs.k8s.io/docs/).
|
||||
<!-- vale on -->
|
||||
|
||||
MiniConstellation uses virtualization to create a local cluster with one control-plane node and one worker node.
|
||||
|
||||
:::info
|
||||
|
||||
MiniConstellation **doesn't** require hardware with Confidential VM (CVM) support.
|
||||
For attestation, MiniConstellation currently uses the software-based vTPM provided by KVM/QEMU.
|
||||
|
||||
:::
|
||||
|
||||
:::note
|
||||
|
||||
Since MiniConstellation runs on your local system, cloud features such as load balancing,
|
||||
attaching persistent storage, or autoscaling aren't available.
|
||||
|
||||
:::
|
||||
|
||||
## Prerequisites
|
||||
|
||||
* A Linux OS with the following components installed
|
||||
* [Constellation CLI](./install.md#install-the-constellation-cli)
|
||||
* [KVM kernel module](https://www.linux-kvm.org/page/Main_Page)
|
||||
* [Docker](https://docs.docker.com/engine/install/)
|
||||
* [xsltproc](https://gitlab.gnome.org/GNOME/libxslt/-/wikis/home)
|
||||
* (Optional) [virsh](https://www.libvirt.org/manpages/virsh.html) to observe and access your nodes
|
||||
* Other system 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)
|
||||
|
||||
## Create your cluster
|
||||
|
||||
The following creates your MiniConstellation cluster (may take up to 10 minutes to complete):
|
||||
|
||||
```bash
|
||||
constellation mini up
|
||||
```
|
||||
|
||||
This will configure your current directory as the [workspace](../architecture/orchestration.md#workspaces) for this cluster.
|
||||
All `constellation` commands concerning this cluster need to be issued from this directory.
|
||||
|
||||
## Connect `kubectl`
|
||||
|
||||
Configure `kubectl` to connect to your local Constellation cluster:
|
||||
|
||||
```bash
|
||||
export KUBECONFIG="$PWD/constellation-admin.conf"
|
||||
```
|
||||
|
||||
Your cluster initially consists of a single control-plane node:
|
||||
|
||||
```shell-session
|
||||
$ kubectl get nodes
|
||||
NAME STATUS ROLES AGE VERSION
|
||||
control-plane-0 Ready control-plane 66s v1.24.6
|
||||
```
|
||||
|
||||
A worker node will request to join the cluster shortly. Before the new worker node is allowed to join the cluster, its state is verified using remote attestation by the [JoinService](../architecture/components.md#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:
|
||||
|
||||
```shell-session
|
||||
$ 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 the worker node has 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:
|
||||
|
||||
```shell-session
|
||||
$ 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](https://github.com/BuoyantIO/emojivoto)
|
||||
|
||||
```bash
|
||||
kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
|
||||
```
|
||||
|
||||
2. Expose the frontend service locally
|
||||
|
||||
```bash
|
||||
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:
|
||||
|
||||
```bash
|
||||
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
|
||||
|
||||
### VMs have no internet access
|
||||
|
||||
`iptables` rules may prevent your VMs from accessing the internet.
|
||||
Make sure your rules aren't dropping forwarded packages.
|
||||
|
||||
List your rules:
|
||||
|
||||
```bash
|
||||
sudo iptables -S
|
||||
```
|
||||
|
||||
The output may look similar to the following:
|
||||
|
||||
```shell-session
|
||||
-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:
|
||||
|
||||
```bash
|
||||
sudo iptables -P FORWARD ACCEPT
|
||||
```

## Create your cluster
|
||||
|
||||
Setting up your MiniConstellation cluster is as easy as running the following command:
|
||||
|
||||
```bash
|
||||
constellation mini up
|
||||
```
|
||||
|
||||
This will configure your current directory as the [workspace](../architecture/orchestration.md#workspaces) for this cluster.
|
||||
All `constellation` commands concerning this cluster need to be issued from this directory.
|
||||
|
||||
The command will create your cluster and initialize it. Depending on your system, this may take up to 10 minutes.
|
||||
The output should look like the following:
|
||||
|
||||
```shell-session
|
||||

You can check on the state of your cluster by running the following:
|
||||
|
||||
```bash
|
||||
kubectl get nodes
|
||||
```
|
||||
|
||||

|
||||
|
||||
```shell-session
|

|
||||
|
||||
```bash
|
||||

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
|
||||
|
||||
### VMs have no internet access
|
||||
|
||||
`iptables` rules may prevent your VMs from accessing the internet.
|
||||
Make sure your rules aren't dropping forwarded packages.
|
||||
|
||||
List your rules:
|
||||
|
||||
```bash
|
||||
sudo iptables -S
|
||||
```
|
||||
|
||||
The output may look similar to the following:
|
||||
|
||||
```shell-session
|
||||
-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:
|
||||
|
||||
```bash
|
||||
sudo iptables -P FORWARD ACCEPT
|
||||
```
