Details

If kube-proxy is running, ensure that the file ownership of its kubeconfig file is set to root:root.

Rationale:

The kubeconfig file for kube-proxy controls various parameters for the kube-proxy service in the worker node. You should set its file ownership to maintain the integrity of the file. The file should be owned by root:root.

Impact:

None

Solution

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

chown root:root

Default Value:

By default, proxy file ownership is set to root:root.
