CKA Practice Task - StorageClass

Question

SSH into the control plane node:

ssh cluster1-controlplane

Create a StorageClass named:

banana-sc-cka08-str

Requirements:

Provisioner: kubernetes.io/no-provisioner
Volume Binding Mode: WaitForFirstConsumer
Volume Expansion enabled

Solution

1. SSH to the node

ssh cluster1-controlplane

2. Create the StorageClass YAML

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: banana-sc-cka08-str

provisioner: kubernetes.io/no-provisioner
allowVolumeExpansion: true
volumeBindingMode: WaitForFirstConsumer

3. Save the file

vim sc.yaml

4. Apply the StorageClass

kubectl apply -f sc.yaml

5. Verify

kubectl get sc banana-sc-cka08-str

kubectl describe sc banana-sc-cka08-str

CKA Exam Tip

StorageClass questions are usually easy points. Remember the three most common fields:

provisioner
volumeBindingMode
allowVolumeExpansion

On the exam, use:

kubectl explain storageclass

if you forget any field names.
