PersistentVolumes
PersistentVolume (PV) is a Kubernetes API resource that represents the mapping relationship between backend storage volumes and the cluster. It is a cluster-related resource that abstracts actual storage resources into the storage infrastructure of the cluster.
Manually create a static PV with HostPath or NFS shared StorageClasses.
Volume snapshot refers to the snapshot of a PV, which is a copy of the PV at a specific point in time. If the cluster uses PVs that support snapshot functionality, the volume snapshot component can be deployed to enable volume snapshot functionality.
