Fix Recommendation

On the Master node, change to the /etc/kubernetes/manifest directory. Run the command:

chmod 644 kubelet

To verify the change took place, run the command:

ls -l kubelet

The kubelet file should now have the permissions of "644".

Check Contents

On the Master and worker nodes, change to the /etc/kubernetes/manifest directory. Run the command:

ls -l kubelet

Each kubelet configuration file must have permissions of "644" or more restrictive.

If any kubelet configuration file is less restrictive than "644", this is a finding.
