Create PVC if possible even if SC is missing
When PVC is created with storageClassName and the SC is not found, k8s looks for PV with the storageClassName for satisfying this claim. In this case k8s supports also a blank (“”, not the nil default one) storageClassName. To support this behavior we added: -DV controller support for this flow (for both “” and non-existing SC) -Condition update and event when StorageSpec PVC rendering errors and PVC is not created (e.g. missing both AccessModes and SC/PV) -PVC is created even if a satisfying SC/PV doesn't exist if pvc/storage AccessModes is set (otherwise k8s PVC validation fails). PVC/DV phase will be Pending until a satisfying SC/PV is found -PV watch to reconcile DVs waiting for the PV storageClassName -PV storageClassName indexer, so we can list the relevant PVs Signed-off-by: Arnon Gilboa <agilboa@redhat.com>
