Decommission cluster on cloudscale

This page documents the steps which are necessary to decommission 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
Access to the cluster

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-decommission.workflow" \
  ${WORKFLOW_DIR}/cloudscale/*.yml
  ${WORKFLOW_DIR}/shared/*.yml

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

Check that all cloudscale resources got deleted via cloudscale control panel.
Clean up remaining VSHN resources related to the decommissioned cluster (wiki pages, open tickets, …).
