Install cluster on cloudscale

This page documents the steps which are necessary to install a VSHN Managed Talos cluster on cloudscale.

Prerequisites

A local gandalf installation
Access to the Project Syn tenant repo
Access to cloudscale
Access to VSHN infrastructure

Steps

We recommend running everything in an empty directory.

Clone the workflow repository

You can use an existing checkout of the workflows repo. If you, make sure that you fetch the latest changes.
```
git clone git@github.com:vshn/managed-talos-workflows
```

Run the Gandalf "cloudscale-install" workflow

WORKFLOW_DIR=./managed-talos-workflows (1)
gandalf run "${WORKFLOW_DIR}/cloudscale-install.workflow" \
  ${WORKFLOW_DIR}/cloudscale/*.yml
  ${WORKFLOW_DIR}/shared/*.yml

1	Adjust this variable to point to the workflow repository checkout.

Download the OIDC kubeconfig and verify that you can access the cluster using your VSHN account

base_domain=$(jq -r '.outputs.base_domain.value' .gandalf-state.json)
cluster_id=$(jq -r '.outputs.commodore_cluster_id.value' .gandalf-state.json)
curl -H"Accept: application/yaml" \
  "https://kubeconfig.apps.${cluster_id}.${base_domain}" \
  -o "${cluster_id}.kubeconfig"
export KUBECONFIG="$(pwd)/${cluster_id}.kubeconfig"
kubectl whoami
kubectl get nodes
