FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Lifecycle Stages of a Persistent Volume and Claim. PVs and PVCs follow a lifecycle that starts with provisioning, moves on to binding, which is followed by using, and then can shift to reclaiming, retaining, and finally deletion.

Detailed explanation-2: -A persistent volume (PV) is a piece of storage in the Kubernetes cluster, while a persistent volume claim (PVC) is a request for storage. There are two ways to use persistent storage in Kubernetes: Use an existing persistent volume. Dynamically provision new persistent volumes.

Detailed explanation-3: -PVs are cluster resources provisioned by an administrator, whereas PVCs are a user’s request for storage and resources. PVCs consume PVs resources, but not vice versa. A PV is similar to a node in terms of cluster resources, while a PVC is like a Pod in the context of cluster resource consumption.

Detailed explanation-4: -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. A PersistentVolumeClaim (PVC) is a request for storage by a user.

Detailed explanation-5: -A PV is a resource object in a Kubernetes cluster which continues to exist even after the pods using it have been destroyed. PVs must be requested through persistent volume claims (PVCs), which are requests for storage. A PVC is essentially a request to mount a PV meeting certain requirements on a pod.
