Mohamed Ayman:
You can check /var/answers Path to validate your answer.

#3

Mohamed Ayman:
You need just to edit /var/answers/answer-5.yaml to use controlplane.

spec:
  nodeSelector:
    <http://kubernetes.io/hostname|kubernetes.io/hostname>: controlplane
#4

Mohamed Ayman:
Then create the deployment:
kubectl create -f /var/answers/answer-5.yaml

Mayur Sharma:
Thanks @Mohamed Ayman for the response, For scheduling the pod, I am using tolerations and nodeaffinity and looks the pod is scheduled on master node as well.

am I doing something wrong or answer would be accepted only if I use nodeSelector.
