Phase 1: Ephemeral Storage (Pod Lifetime)

Temporary storage that dies with the Pod.

1. empty-dir

   → Basic emptyDir volume (shared between containers in a Pod).

2. empty-dir-multiple

   → Multiple emptyDir volumes or shared between multiple containers.

Phase 2: Pod Volumes (External Sources)

Mount external storage into Pods.

1. pod-with-volume.yml

   → Basic volume mount (likely hostPath or config).

2. pod-with-volume-external.yml

   → Volume from external source (e.g., NFS, cloud disk).

Phase 3: Persistent Volumes (PV/PVC)

Decouple storage from Pods for true persistence.

1. persistent-volume-nfs.yaml

   → PersistentVolume (PV) backed by NFS.

2. pvc-nfs.yaml

   → PersistentVolumeClaim (PVC) requesting NFS storage.

3. storage-class-nfs

   → StorageClass for dynamic NFS provisioning (advanced).

Phase 4: Stateful Workloads

Use PVCs in real applications.
