Reconfigure the existing deployment front-end and add a port specification named http exposing port 80/tcp of the existing container nginx.
Create a new service named front-end-svc exposing the container port http.
Configure the new service to also expose the individual Pods via a NodePort on the nodes on which they are scheduled.

Q29. Create a deployment as follows:
* Name: nginx-random
* Exposed via a service nginx-random
* Ensure that the service & pod are accessible via their respective DNS records
* The container(s) within any pod(s) running as a part of this deployment should use the nginx Image Next, use the utility nslookup to look up the DNS records of the service & pod and write the output to
/opt/KUNW00601/service.dns and /opt/KUNW00601/pod.dns respectively.

Q30. Score: 5%

Q31. Check the history of deployment

Q32. Verify certificate expiry date for ca certificate in /etc/kubernetes/pki

Q33. Create 2 nginx image pods in which one of them is labelled with env=prod and another one labelled with env=dev and verify the same.

Q34. On the NGFW, how can you generate and block a private key from export and thus harden your security posture and prevent rogue administrators or other bad actors from misusing keys?

Q35. Configure the kubelet systemd- managed service, on the node labelled with name=wk8s-node-1, to launch a pod containing a single container of Image httpd named webtool automatically. Any spec files required should be placed in the /etc/kubernetes/manifests directory on the node.
You can ssh to the appropriate node using:
[student@node-1] $ ssh wk8s-node-1
You can assume elevated privileges on the node with the following command:
[student@wk8s-node-1] $ | sudo -i

Q36. Create a busybox pod and add “sleep 3600” command

Q37. Create 2 nginx image pods in which one of them is labelled with env=prod and another one labelled with env=dev and verify the same.

Q38. Create an nginx pod and load environment values from the above configmap “keyvalcfgmap” and exec into the pod and verify the environment variables and delete the pod

Q39. List all persistent volumes sorted by capacity, saving the full kubectl output to /opt/KUCC00102/volume_list. Use kubectl ‘s own functionality for sorting the output, and do not manipulate it any further.

Q40. Add a taint to node “worker-2” with effect as “NoSchedule” and
list the node with taint effect as “NoSchedule”

Q41. Score: 4%
