Persistent Volumes & Storage
Part of the DevOps Roadmap
In short
Kubernetes' abstraction for durable storage that survives Pod restarts — PersistentVolumes represent actual storage, PersistentVolumeClaims are how a Pod requests it.
How to learn this
- 1Create a PersistentVolumeClaim and mount it in a Pod, then verify data survives a Pod restart.
- 2Learn the difference between a PersistentVolume and a PersistentVolumeClaim.
- 3Understand why stateful applications (like databases) need this, while stateless apps often don't.
