4.1.1 Ensure that the kubelet service file permissions are set to 600 or more restrictive

Information

Ensure that the kubelet service file has permissions of 600 or more restrictive.

Rationale:

The kubelet service file controls various parameters that set the behavior of the kubelet service in the worker node. You should restrict its file permissions to maintain the integrity of the file. The file should be writable by only the administrators on the system.

Impact:

None

Solution

Run the below command (based on the file location on your system) on each worker node. For example,

chmod 600 /etc/systemd/system/kubelet.service.d/kubeadm.conf

Default Value:

By default, the kubelet service file has permissions of 640.
