Summary
ref Managing storage is a distinct problem from managing compute instances. The PersistentVolume subsystem provides an API for users and administrators that abstracts details of how storage is provided from how it is consumed . To do this, we introduce two new API resources: PersistentVolume and PersistentVolumeClaim.
A PersistentVolume (PV)
is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes.
-
It is a resource in the cluster just like a node is a cluster resource .
-
PVs are volume plugins like Volumes, but have a lifecycle independent of any individual Pod that uses the PV.
-
This API object captures the details of the implementation of the storage, be that NFS, iSCSI, or a cloud-provider-specific storage system.
