cluster-api-cleaner-openstack

An helper operator for CAPO to delete resources by workload clusters

How does it work?

• It observes OpenStackCluster objects.
• It doesn't do anything in reconcileNormal other than adding finalizer.
• It respects cluster.x-k8s.io/cluster-name label in OpenStackCluster objects to get the actual cluster names.
• clusterTag is built as giant_swarm_cluster_<management-cluster-name>_<workload_cluster-name>.
• When an OpenStackCluster is deleted, it
  • cleans volumes ( whose metadata contains cinder.csi.openstack.org/cluster: <clusterTag> ) created by Cinder CSI
  • cleans loadbalancers ( whose tags contain kube_service_<clusterTag>.* ) created by openstack-cloud-controller-manager
