Description: A PersistentVolumeClaim (PVC) in Kubernetes is a storage request made by a user that allows containerized applications to access persistent storage resources. PVCs are a fundamental part of Kubernetes’ storage model, enabling developers to abstract the complexity of the underlying storage. When creating a PVC, the user specifies storage requirements such as the amount of space and access mode (e.g., read/write or read-only). Kubernetes then searches for a PersistentVolume (PV) that meets these specifications and binds it to the PVC. This allows applications to retain their data even if containers are restarted or deployed on different nodes. PVCs are particularly useful in production environments where data persistence is critical, such as in databases and shared file systems. Additionally, they facilitate storage management by allowing developers to focus on application logic rather than storage infrastructure.
