Topic 1 · Question 15

SIMULATION - Task - 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.

Suggested solution

kubectl describe node wk8s-node-0
ssh wk8s-node-0
sudo systemctl status kubelet
sudo systemctl enable --now kubelet
sudo systemctl restart kubelet
exit
kubectl get node wk8s-node-0

Enabling and restarting kubelet fixes the common NotReady cause and ensures the service returns after reboot.
