3.1.4 Ensure that the kubelet configuration file ownership is set to root:root (Automated)


This rule has been changed to automated, see Automated Policies for CIS Amazon EKS 1.1.0 for details.

Profile Applicability

• Level 1


Ensure that if the kubelet refers to a configuration file with the --config argument, that file is owned by root:root.


The kubelet reads various parameters, including security settings, from a config file specified by the --config argument. If this file is specified 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.




First, SSH to the relevant worker node:

To check to see if the Kubelet Service is running:

sudo systemctl status kubelet

The output should return Active: active (running) since..

Run the following command on each node to find the appropriate Kubelet config file:

ps -ef | grep kubelet

The output of the above command should return something similar to --config /etc/kubernetes/kubelet/kubelet-config.json which is the location of the Kubelet config file.

Run the following command:

stat -c %U:%G /etc/kubernetes/kubelet/kubelet-config.json

The output of the above command is the Kubelet config file's ownership. Verify that the ownership is set to root:root


Run the following command (using the config file location identified in the Audit step):

chown root:root /etc/kubernetes/kubelet/kubelet-config.json
