24. Kubernetes PVs & PVCs Demo in Minikube

Learn how to use Kubernetes Persistent Volumes (PVs) and Persistent Volume Claims (PVCs) in this Minikube hands-on demo. Pods in Kubernetes are temporary, but with persistent storage you can keep your data safe even after restarts or deletions. In this tutorial, you’ll see how to create PVs and PVCs, mount them in Pods, test data persistence, and troubleshoot common issues like PVC stuck in Pending or Terminating, and PV stuck in Failed state. Perfect for developers, DevOps engineers, and system administrators who want to understand Kubernetes storage step by step.

✔️ Start Minikube & clean setup
✔️ Create Persistent Volume & PVC
✔️ Mount PVC in Pod & write data
✔️ Test persistence after Pod deletion
✔️ Reclaim policies: Retain vs Delete
✔️ Fix stuck PVCs & PVs like a pro
