A Persistent Volume Claim (PVC) in Kubernetes is a request for storage by a user. It is used to allocate storage resources from a Persistent Volume (PV). PVCs allow users to specify the desired storage size and access modes without needing to know the details of the underlying storage infrastructure.
When a PVC is created, Kubernetes looks for a matching PV that meets the requested criteria. If a suitable PV is found, it is bound to the PVC, allowing Pods to use the storage defined by the PVC. This abstraction helps manage storage independently from the lifecycle of Pods, ensuring data persistence even if Pods are deleted or recreated.
