Linux Foundation CKA Exam Dumps

Task Summary

You need to:

SSH into cka000046

Create a StorageClass named local-path using the provisioner rancher.io/local-path

Set the volume binding mode to WaitForFirstConsumer

Make this StorageClass the default

Step-by-Step Solution

1 SSH into the correct host

ssh cka000046

Required. Skipping this = zero score

2 Create a StorageClass YAML file

Create a file named local-path-sc.yaml:

cat <<EOF > local-path-sc.yaml

apiVersion: storage.k8s.io/v1

kind: StorageClass

metadata:

name: local-path

annotations:

storageclass.kubernetes.io/is-default-class: 'true'

provisioner: rancher.io/local-path

volumeBindingMode: WaitForFirstConsumer

EOF

This:

Sets WaitForFirstConsumer (as required)

Marks the class as default using the correct annotation

3 Apply the StorageClass

kubectl apply -f local-path-sc.yaml

4 Verify it's the default StorageClass

kubectl get storageclass

You should see local-path with a (default) marker:

NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE

local-path rancher.io/local-path Delete WaitForFirstConsumer false 10s
