Reclaim a Retained PV with a New PVC and Restore a Lost MariaDB Database
by Omkar Shelke
A MariaDB deployment and its PVC were accidentally deleted. The PersistentVolume survived due to its Retain policy. Restore the database by rebinding the existing PV without losing any data.
Challenge on Kubernetes
Kubernetes - PV Reclaim Policies and Recovery
Observe the Delete and Retain reclaim policies in action, recover a Released PV by patching claimRef, and recover data by creating a new PV pointing to the same storage directory.
Challenge on Kubernetes
Kubernetes - Dynamic Provisioning with StorageClass
Explore how the DefaultStorageClass admission controller injects storage classes, explicitly name a StorageClass, switch the cluster default, and inspect where local-path stores volumes on the node.
Linux Storage 101: Drives, Partitions, and Mounts
Practice the most common Linux storage operations in a series of hands-on challenges: discover and mount drives, create partition tables, format partitions with different filesystems, map directories with bind mounts, and make mount points survive a reboot.
Kubernetes Storage: From Ephemeral to Persistent
Four hands-on challenges covering the full storage stack. Start with emptyDir, move to dynamic provisioning with StorageClass, explore static PV binding patterns including label selectors, bidirectional claimRef, and topology-aware local volumes, then finish with PV reclaim policies and data recovery.
