Question 26

A Kubernetes worker node, named wk8s-node-0 is in state NotReady. Investigate why this is the case, and perform any appropriate steps to bring the node to a Ready state, ensuring that any changes are made permanent.
You can ssh to the failed node using:
[student@node-1] $ | ssh Wk8s-node-0
You can assume elevated privileges on the node with the following command:
[student@w8ks-node-0] $ | sudo -i

    Save a copy of this spec file to /opt/KUAL00201/spec_deployment.yaml
    (or /opt/KUAL00201/spec_deployment.json).
    When you are done, clean up (delete) any new Kubernetes API object that you produced during this task.
