Pods consume node resources and PVCs consume PV resources. ![]() This API object captures the details of the implementation of the storage, be that NFS, iSCSI, or a cloud-provider-specific storage system.Ī PersistentVolumeClaim (PVC) is a request for storage by a user. PVs are volume plugins like Volumes, but have a lifecycle independent of any individual Pod that uses the PV. It is a resource in the cluster just like a node is a cluster resource. To do this, we introduce two new API resources: PersistentVolume and PersistentVolumeClaim.Ī PersistentVolume (PV) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes. The PersistentVolume subsystem provides an API for users and administrators that abstracts details of how storage is provided from how it is consumed. ![]() Managing storage is a distinct problem from managing compute instances. Volume Snapshot and Restore Volume from Snapshot Support.This document describes the current state of PersistentVolumes in Kubernetes.
