Description

As an openshift operator, sometimes I could want to bind my pvc to a pv without any storage class.

To be able to do this on a cluster with a default sotrage class I should set storageClassName: '' on the pvc spec:

https://docs.openshift.com/container-platform/4.7/storage/understanding-persistent-storage.html#pvc-storage-class_understanding-persistent-storage

When a default storage class is configured, the PVC must explicitly ask for StorageClass or storageClassName annotations set to "" to be bound to a PV without a storage class.

But the operator won't set a storageClassName when the respective var's value is '' :
