Exam CKA topic 1 question 3 discussion

--etcd-upgrade Perform the upgrade of etcd. (default true) The default etcd upgrade is true, so disable it with sudo kubeadm upgrade apply v1.** --etcd-upgrade=false

not exactly like in the exam. but it helps. do not relay on dumps only. i recommend to study with kodekloud and the corresponding udemy course.

kubectl config view kubectl config use-context mk8s kubectl get nodes kubectl cordon mk8s-master-0 kubectl drain mk8s-master-0 –ignore-daemonsets --force ssh mk8s-master0 sudo -i apt install kubeadm=1.22.2-00 kubelet=1.22.2.-00 kubectl=1.22.2-00 kubeadm upgrade plan kubeadm upgrade apply 1.22.2 --etcd-upgrade=false systemctl restart kubelet daemon-reload exit exit kubectl uncordon mk8s-master-0 kubectl get nodes

$ kubectl config use-config eks8 $ kubectl cordon ek8s-node-1 $ kubectl drain ek8s-node-1 --delete-local-data --ignore-daemonsets --force This is much more understandable solution for me

Would those steps be right? 1. k cordon nodename; 2. k drain --ignore-daemonsets nodename; 3. ssh into node; 4. swapoff -a; 5. then find swap line in /etc/fstab and comment it out; 6. run apt-mark unhold kubeadm kubelet kubectl && \ apt-get update && apt-get install -y kubeadm=1.2xx-00 kubelet=1.2x.x-00 kubectl=1.2x.x-00&& \ apt-mark hold kubeadm kubelet kubectl 7. sudo systemctl daemon-reload 8. sudo systemctl restart kubelet 9. exit ssh 10.k uncordon node

we need to set --etcd-upgrade=false, question says so not upgrade the etcd

I has this question on the exam, you can follow the steps below to complete it, just ensure that you are ssh-ing from the right node: https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/#upgrading-control-plane-nodes
