CKAD Questions and Answers

Task:

Update the Deployment app-1 in the frontend namespace to use the existing ServiceAccount app.

Context

As a Kubernetes application developer you will often find yourself needing to update a running application.

Task

Please complete the following:

• Update the app deployment in the kdpd00202 namespace with a maxSurge of 5% and a maxUnavailable of 2%

• Perform a rolling update of the web1 deployment, changing the Ifccncf/ngmx image version to 1.13

• Roll back the app deployment to the previous version

Context

It is always useful to look at the resources your applications are consuming in a cluster.

Task

• From the pods running in namespace cpu-stress , write the name only of the pod that is consuming the most CPU to file /opt/KDOBG030l/pod.txt, which has already been created.

Context

A project that you are working on has a requirement for persistent data to be available.

Task

To facilitate this, perform the following tasks:

• Create a file on node sk8s-node-0 at /opt/KDSP00101/data/index.html with the content Acct=Finance

• Create a PersistentVolume named task-pv-volume using hostPath and allocate 1Gi to it, specifying that the volume is at /opt/KDSP00101/data on the cluster's node. The configuration should specify the access mode of ReadWriteOnce . It should define the StorageClass name exam for the PersistentVolume , which will be used to bind PersistentVolumeClaim requests to this PersistenetVolume.

• Create a PefsissentVolumeClaim named task-pv-claim that requests a volume of at least 100Mi and specifies an access mode of ReadWriteOnce

• Create a pod that uses the PersistentVolmeClaim as a volume with a label app: my-storage-app mounting the resulting volume to a mountPath /usr/share/nginx/html inside the pod
