Running on Openshift currently fails with:
failed to apply patch: unable to patch resource "listener-nginx-long-name-approaching-k8s-limits-0": ApiError: services "listener-nginx-long-name-approaching-k8s-limits-0" is forbidden: cannot set blockOwnerDeletion if an ownerReference refers to a resource you can't set finalizers on: , <nil>: Forbidden

Fixed Clusterrole (this will be covered in a separate PR, so that this one can be merged):

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
...
rules:
...
  resources:
  - persistentvolumes
  verbs:
  - get
  - list
  - watch
  - patch
  - create
  - delete
- apiGroups:

  resources:
  - nodes
  - persistentvolumes
  - persistentvolumes/finalizers
  - persistentvolumeclaims
