To use the CSO to download and install this ClusterClass you can apply the following resource:

apiVersion: clusterstack.x-k8s.io/v1alpha1
kind: ClusterStack
metadata:
  name: openstack-scs-1-27-v2
spec:
  provider: openstack
  name: scs
  kubernetesVersion: "1.27"
  channel: stable
  autoSubscribe: false
  noProvider: true
  versions:
    - v2

To create a cluster you need a secret to authenticate against your OpenStack provider:

apiVersion: v1
kind: Secret
metadata:
  name: openstack-scs-1-27-v2-cloud-config
data:
  cacert: <base64 of a CA that signs the openstack API endpoint>
  clouds.yaml: <base64 of the openstack clouds.yaml> # make sure that the name of the cloud is the same as the one referenced in openstackcluster.spec.cloudName

After that you can create your cluster with the normal Cluster-API cluster resource. Some cluster-class specific variables are mentioned in this example too, you can alter them to fit your needs. For the full list of possible variables you can check out the cluster-class resource unter .spec.variables
