  • default
  • pvc

What you will practise

  • Set the default StorageClass annotation
  • Create a PVC that relies on the default class
  • Observe binding behaviour of a WaitForFirstConsumer class

Start this lab

With the CLI installed and signed in, this command provisions a single node cluster on your Mac, applies the scenario setup and prints the task below.

goldenkube start cka-sto-003

Task

The task text exactly as the CLI shows it. Solve it on the cluster, then run goldenkube submit.

The cluster has a StorageClass "local-path" that is currently NOT the default class. Make "local-path" the cluster default StorageClass. Then, in namespace "data" (create it if missing), create a PersistentVolumeClaim named "auto-pvc" requesting 1Gi, accessMode ReadWriteOnce, WITHOUT specifying any storageClassName, so that the default class is applied. Finally create a Pod named "auto-pod" (image nginx:1.27) in namespace "data" that mounts "auto-pvc" at /mnt/auto. The PVC must be Bound and the pod Running.

Grading runs locally: 7 state checks read your cluster when you submit; the scenario passes when every check passes. Hints, the reference solution and the check definitions are available only inside the CLI, not on this page.
