Edit the Kubernetes API Server manifest file in the /etc/kubernetes/manifests directory on the Kubernetes Master Node. Set the value of "--kubelet-client-certificate" and "--kubelet-client-key" to an Approved Organizational Certificate and key pair.

Check Contents

Change to the /etc/kubernetes/manifests/ directory on the Kubernetes Master Node. Run the command:

grep -i kubelet-client-certificate *
