Information
Ensure that the 'kubelet.conf' file has permissions of '644' or more restrictive.
Rationale:
The 'kubelet.conf' file is the kubeconfig file for the node, and controls various parameters that set the behavior and identity of 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.
Solution
Run the below command (based on the file location on your system) on the each worker node. For example,
chmod 644 /etc/kubernetes/kubelet.conf
