Kubernetes CKA sample exam question 19 with answer

Question
Worker node node01 not responding. Have a look and fix the issue.

Answer
Get the environment details:

kubectl get nodes
kubectl describe node node01

we can see that node01 is in a NotReady state. From describe command we can't get too many details.
SSH to node01:

ssh node01

Check kubelet status:

systemctl status kubelet

We can see that the service is in inactive state. Seems that it is simply died.
Start again the kubelet and check the status:

systemctl start kubelet
systemctl status kubelet

Now, it is running, exit the node01 and check the cluster status:

kubectl get nodes

Now, the node01 is in the Ready state
