Labs from Udemy

hi sir

This lab of Udemy CKA course has issues in Question 11

Upgrade the worker node to the exact version v1.18.0

The worker node is not getting upgraded to 18.
even after running
kubeadm upgrade node
apt install kubelet=1.18.0-00

i am not sure why the node is not getting upgraded.
I followed the same procedure.
Need to clarify it.

Hello, vpernankil
First, you need to check the cluster version. What is the version of the cluster before upgrade into the specific version.
When you will do kubeadm upgrade plan. You will see the status of cluster version. After analysis the cluster version. Perform the upgrade procedure as per k8s version skew policy.
Hope this will help you or will give you lead.
