How do PersistentVolumes (PV) and PersistentVolumeClaims (PVC) manage storage in Kubernetes?

Explanation & Concept

• PersistentVolume (PV): A piece of storage in the cluster provisioned by an administrator or dynamically provisioned using StorageClasses. • PersistentVolumeClaim (PVC): A user's request for storage, specifying size and access modes (`ReadWriteOnce`, `ReadWriteMany`).

Code Example

yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: db-data-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 20Gi

How It Works & Key Takeaways

Pods mount the PVC without needing to know whether the physical storage is an AWS EBS volume, Google Persistent Disk, or NFS share.
