How Persistent Storage Works. A persistent volume (PV) is a piece of storage in the Kubernetes cluster, while a persistent volume claim (PVC) is a request for storage. To use an existing PV, your application will need to use a PVC that is bound to a PV, and the PV should include the minimum resources that the PVC requires.

Familiarity with volumes and persistent volumes is suggested. A StorageClass provides a way for administrators to describe the classes of storage they offer. Different classes might map to quality-of-service levels, or to backup policies, or to arbitrary policies determined by the cluster administrators. Kubernetes itself is ... The claim can allow cluster workers to read and write database records, user-generated website content, log files, and other data that should persist after a process has completed. When managing persistent volume claims: Deleting a deployment will not automatically delete any PVCs that have been created.
Enabling a container to persist its data between sessions is a two-stage process. Firstly the disk resource has to be defined (the Persistent Volume), then it needs to be assigned to the container (Persistent Volume Claim). This section will complete the first of these. Create the Persistent Volume Claim YAML file.
