Developers can use persistent volume claims (PVCs) to request PV resources without having specific knowledge of the underlying storage infrastructure.

How do you attach PVC to pods?

Configure a Pod to Use a PersistentVolume for Storage

1. You, as cluster administrator, create a PersistentVolume backed by physical storage. ...
2. You, now taking the role of a developer / cluster user, create a PersistentVolumeClaim that is automatically bound to a suitable PersistentVolume.
3. You create a Pod that uses the above PersistentVolumeClaim for storage.
