Certified Kubernetes Administrator (CKA): Practice Exam: Part 6

30 minutes

2 Learning Objectives

About this Hands-on Lab

This lab provides practice scenarios to help prepare you for the Certified Kubernetes Administrator (CKA) Exam. You will be presented with tasks to complete, as well as server(s) and/or an existing Kubernetes cluster to complete them in. You will need to use your knowledge of Kubernetes to successfully complete the provided tasks, much like you would on the real CKA exam. Good luck!

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Drain Worker Node 1

Drain the acgk8s-worker1 node.
Note: Note that you may run into issues with this process. If you do, use the appropriate command-line flags to force the drain process to proceed anyway.

Create a Pod That Will Only Be Scheduled on Nodes with a Specific Label

Add the disk=fast label to the acgk8s-worker2 Node.
Create a pod called fast-nginx in the dev namespace that will only run on nodes with this label. Use the nginx image for this pod.

Additional Resources

This question uses the acgk8s cluster. After logging in to the exam server, switch to the correct context with the command kubectl config use-context acgk8s.

Each of the objectives represents a task which you will need to complete using the available cluster and server(s). Read each objective carefully and complete the task specified.

For some objectives, you may need to ssh into other nodes or servers from the exam server. You can do so using the hostname/node name, i.e. ssh acgk8s-worker1.

Note: You cannot ssh into another node, or use kubectl to connect to the cluster, from any node other than the root node. Once you have completed the necessary tasks on a server, be sure to exit and return to the root node before proceeding.

If you need to assume root privileges on a server, you can do so with sudo -i.

You can run the verification script located at /home/cloud_user/verify.sh at any time to check your work!
