Overview

Description

Ensure that the kubelet.conf file ownership is set to root:root.

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 set its file ownership to maintain the integrity of the file. The file should be owned by root:root.

Audit

Run the following command (based on the file location on your system) on the each worker node. For example, stat -c %U:%G /etc/kubernetes/kubelet.conf. Verify that the ownership is set to root:root.

Remediation

Run this command (based on the file location on your system) on the each worker node. For example, chown root:root /etc/kubernetes/kubelet.conf

Impact

None

Default Value

By default, kubelet.conf file ownership is set to root:root.
