Explain how a PersistentVolumeClaim provides storage to a Pod.

Explanation:
PersistentVolumeClaim is the mechanism that requests persistent storage for a Pod, using a StorageClass to drive provisioning. When a Pod uses a PVC, the system provisions storage through the StorageClass (either dynamically or by binding to an existing PV that matches) and then binds the PVC to a suitable PersistentVolume. Once bound, the Pod can mount that PVC as a volume, making the storage available to the containers. This flow—PVC requesting storage via a StorageClass, OpenShift binding to a PV, and the Pod mounting the PVC as a volume—captures how persistent storage is provisioned and consumed in OpenShift.
