Linux Foundation Certified Kubernetes Administrator (CKA) Program Exam Sample Questions (Q30-Q35):

Create the nginx pod with version 1.17.4 and expose it on port 80


kubectl run nginx --image=nginx:1.17.4 --restart=Never -- port=80

Create a persistent volume with nameapp-data, of capacity2Giandaccess modeReadWriteMany. Thetype of volume ishostPathand itslocation is/srv/app-data.


See the solution below.
Persistent Volume
A persistent volume is a piece of storage in aKubernetes cluster. PersistentVolumes are a cluster-level resource like nodes, which don't belong to any namespace. It is provisioned by the administrator and has a particular file size. This way, a developer deploying their app on Kubernetes need not knowthe underlying infrastructure.
When the developer needs a certain amount of persistent storage for their application, the system administrator configures the cluster so that they consume the PersistentVolume provisioned in an easy way.
Creating PersistentVolume
kind: PersistentVolumeapiVersion: v1metadata:name:app-dataspec:capacity: # defines the capacity of PV we are creatingstorage:2Gi#the amount of storage we are tying to claimaccessModes: # defines the rights of the volumewe are creating-ReadWriteManyhostPath:path: "/srv/app-data" # path to which we are creating the volume Challenge
* Create a Persistent Volume named ReadWriteMany, storage classname
shared,2Giof storage capacity and the host path
2. Save the file and create the persistent volume.
Image for post
3. View the persistent volume.
* Our persistent volume status is available meaning it is available and it has not been mounted yet. This status willchange when we mount the persistentVolume to a persistentVolumeClaim.
In a real ecosystem, a system admin will create the PersistentVolume then a developer will create a PersistentVolumeClaim which will be referenced in a pod. A PersistentVolumeClaim is created by specifying the minimum size and the access mode they require from the persistentVolume.
* Create a Persistent Volume Claim that requests the Persistent Volume we had created above. The claim should request 2Gi. Ensurethat the Persistent Volume Claim has the same storageClassName as the persistentVolume you had previously created.
kind: PersistentVolumeapiVersion: v1metadata:name:
2. Save and create the pvc
njerry191@cloudshell:~(extreme-clone-2654111)$ kubect1 create -f app-data.yaml persistentvolumeclaim/app-data created
3. View the pvc

4. Let's see what has changed in the pv we had initially created.

Our status has now changed fromavailabletobound.
5. Create a new pod named myapp with image nginx that will be used to Mount the Persistent Volume Claim with the path /var/app/config.

Create a job named "hello-job" with the image busybox which echos "Hello I'm running job"

  • A. kubectl create job hello-job --image=busybox --dry-run -o yaml
    -- echo "Hello I'm running job" > hello-job.yaml
    kubectl create -f hello-job.yaml
    //Verify Job
    kubectl get job
    kubectl get po
    kubectl logs hello-job-*
  • B. kubectl create job hello-job --image=busybox --dry-run -o yaml
    -- echo "Hello I'm running job" > hello-job.yaml
    kubectl create -f hello-job.yaml
    //Verify Job
    kubectl get po
    kubectl logs hello-job-*

Answer: A

Check the history of deployment


kubectl rollout history deployment webapp
