There is a question which is a bit confusing.
Set the node named node-1 as unavailable and reschedule all the pods running on it.
What will be the correct solution for it?
- Cordon first and then drain OR
- Drain it which will do both the things as per lecture video.
Second question is about significance of using keyword “–disableexcludes=kubernetes” in the command “apt-get install kubeadm=1.20.0-00 kubelet=1.20.0-00 iidisableexcludes=kubernetes” during cluster upgrade.
