Kubernetes Persistent Volumes – Tutorial and Examples

Kubernetes Persistent Volumes (PVs) provide storage for applications' Pods, ensuring data persistence even after Pod restarts or failures. PVs are crucial when deploying stateful applications like databases and file servers using Kubernetes. They abstract away the differences between cluster storage implementations and work in conjunction with Persistent Volume Claims (PVCs). This article explains how PVs function, their types, access modes, lifecycle stages, and provides an example of creating and using a Persistent Volume. Additionally, it outlines best practices for managing PVs effectively.
