What is PersistentVolume (PV)?
A piece of storage in a Kubernetes cluster provisioned for use by pods.
A PersistentVolume (PV) is a storage resource in the Kubernetes cluster that has been provisioned statically by an admin or dynamically by a StorageClass. PVs have a lifecycle independent of any pod that uses them — data persists when pods are deleted. PVs are cluster-scoped resources. They are bound to PersistentVolumeClaims (PVCs) which are namespace-scoped requests for storage. The StorageClass determines the type and properties of the underlying storage.
