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!
