The task
A MariaDB Deployment in namespace mariadb was deleted by mistake. A retained PV named mariadb-pv (300Mi, storageClass: standard) already exists.
Task 1: Create a PVC in namespace mariadb:
- Name:
mariadb - Storage:
250Mi - AccessMode:
ReadWriteOnce - Must bind to the existing PV
mariadb-pv
Task 2: Update ~/mariadb-deployment.yaml to mount the PVC at /var/lib/mysql and apply it.
What this tests
Configure persistent volumes, claims, storage classes, and volume access modes. On the CKA exam, Storage tasks are graded purely on what you build in the cluster — not multiple choice — so the only way to get faster is to do them on a real cluster against a clock.
Practice it for real
prepium.sh drops you into your own isolated Kubernetes cluster in the browser — no install, no credit card. You solve the task in a real terminal, hit validate, and a programmatic checker scores exactly what you got right and wrong (with partial credit). The canonical solution unlocks after you attempt it, so you learn the fast, exam-ready way to do it.
