  # TODO: As a future improvement, if we add topology support to the mock driver, 
  # then we don't need podAffinity in this pod. The pv provisioned will have a 
  # nodeaffinity on it, and the pod will always get scheduled to the correct node.
  #
  # Deploy this pod only on where csi-mock-driver exists.
  # This is because csi-mock-driver keeps all states in memory and the process that
  # provisioned the PV needs to be the same process that's mounting it.
