Fix Recommendation

On the Kubernetes Control Plane and Worker nodes, run the command:
ps -ef | grep kubelet

Check the config file (path identified by: --config):

Change to the directory identified by --config (example /etc/sysconfig/) and 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 Kubernetes Control Plane and Worker nodes, run the command:
ps -ef | grep kubelet

Check the config file (path identified by: --config):

Change to the directory identified by --config (example /etc/sysconfig/) and run the command:
ls -l kubelet

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

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