# Quick setup for a mini cluster running the cloud
|
|
|
|
### Prerequisites
|
|
|
|
* [Install Terraform](https://developer.hashicorp.com/terraform/downloads)
|
|
* [Install the Azure CLI](https://learn.microsoft.com/de-de/cli/azure/install-azure-cli)
|
|
to authenticate with Azure:
|
|
|
|
```sh
|
|
az login
|
|
```
|
|
|
|
### Instructions
|
|
|
|
Through the Terraform template for Azure it's easy to set up a MiniConstellation cluster on a remote VM.
|
|
|
|
1. Clone the Constellation repository:
|
|
|
|
```sh
|
|
git clone https://github.com/edgelesssys/constellation.git
|
|
```
|
|
|
|
2. Set up the remote Azure VM through Terraform:
|
|
|
|
By default, the [`Standard_D8s_v5`](https://learn.microsoft.com/de-de/azure/virtual-machines/dv5-dsv5-series) machine type is selected which supports nested virtualization, but you can also set another supported machine type in Terraform (`machine_type`) by referring to the [Azure docs](https://azure.microsoft.com/en-us/blog/nested-virtualization-in-azure/).
|
|
Then run:
|
|
|
|
```sh
|
|
cd constellation/dev-docs/miniconstellation/azure-terraform
|
|
./create-vm.sh
|
|
```
|
|
|
|
After execution, you should be connected with the remote machine through SSH.
|
|
If you accidentally lose connection, you can reconnect via
|
|
|
|
```sh
|
|
ssh -i id_rsa adminuser@$INSERT_VM_IP_ADDRESS
|
|
```
|
|
|
|
3. Prepare the VM for `constellation mini up`
|
|
|
|
Once logged into the machine, install the Constellation CLI:
|
|
|
|
```sh
|
|
echo "Installing Constellation CLI"
|
|
curl -LO <https://github.com/edgelesssys/constellation/releases/latest/download/constellation-linux-amd64>
|
|
sudo install constellation-linux-amd64 /usr/local/bin/constellation
|
|
```
|
|
|
|
and start the Docker service and make sure that it's running:
|
|
|
|
```sh
|
|
sudo systemctl start docker.service && sudo systemctl enable docker.service
|
|
# verify that it is active
|
|
systemctl is-active docker
|
|
```
|
|
|
|
At last, create the Constellation cluster in a workspace directory:
|
|
|
|
```sh
|
|
mkdir constellation_workspace && cd constellation_workspace
|
|
constellation mini up
|
|
```
|
|
|
|
The cluster creation takes about 15 minutes.
|
|
|
|
For convenience, there is a script that does these steps automatically:
|
|
|
|
```sh
|
|
./setup-miniconstellation.sh
|
|
```
|
|
|
|
4. Verify the Kubernetes cluster
|
|
|
|
Running:
|
|
|
|
```sh
|
|
export KUBECONFIG="$PWD/constellation-admin.conf"
|
|
kubectl get nodes
|
|
```
|
|
|
|
should show both one control-plane and one worker node.
|
|
|
|
5. Clean up cloud resources
|
|
|
|
Exit the SSH connection (Ctrl+D) and run:
|
|
|
|
```sh
|
|
terraform destroy
|
|
```
|
