Unable to complete Q5 of lab-api-versions-deprecations
I will appreciate if you can guide me how to solve this question.
Enable the v1alpha1 version for rbac.authorization.k8s.io API group on the controlplane node.
Thank you for
Hello @srungaram,
As a good practice, take a backup of that apiserver manifest file before going to make any changes.
In case, if anything happens due to misconfiguration you can replace it with the backup file.
root@controlplane:~# cp -v /etc/kubernetes/manifests/kube-apiserver.yaml /root/kube-apiserver.yaml.backup
Now, open up the kube-apiserver manifest file in the editor of your choice. It could be vim or nano .
root@controlplane:~# vi /etc/kubernetes/manifests/kube-apiserver.yaml
Add the --runtime-config flag in the command field as follows :-
- command:
- kube-apiserver
- --advertise-address=10.18.17.8
- --allow-privileged=true
- --authorization-mode=Node,RBAC
- --client-ca-file=/etc/kubernetes/pki/ca.crt
- --enable-admission-plugins=NodeRestriction
- --enable-bootstrap-token-auth=true
- --runtime-config=rbac.authorization.k8s.io/v1alpha1 --> This one
After that kubelet will detect the new changes and will recreate the apiserver pod.
It may take some time.
root@controlplane:~# kubectl get po -n kube-system
Check the status of the apiserver pod. It should be in running condition.
Thanks,

Thank you @Ayman really appreciate your solution.
I took CKAD exam recently and I am able to get only 63% when the pass score is 66%. Anyway I came across one question which is based on API deprecations.
I don’t remember the entire question something like this…
‘old deployment with extensions/v1beta1’ under 1.15, this needs to be migrated to non deprecated version.
My question is, are we allowed to use kubectl-convert in the exam?
