Information
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.
Solution
Run the below command (based on the file location on your system) on the each worker node. For example,
chown root:root <proxy kubeconfig file>
Impact:
None
Default Value:
By default, proxy file ownership is set to root:root.
