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

MediumLevel 1Automatedopenshift

Description

Ensure that the kubelet.conf file ownership is set to root:root. Runs on each OpenShift node (for example from an oc debug node shell with chroot /host); SKIPs where the file is absent.

How it is checked

Audit method: Shell command

shell

set -f
f=""; for x in /etc/kubernetes/kubelet.conf; do if [ -e "$x" ]; then f=$x; break; fi; done
[ -n "$f" ] || exit 1
o=$(stat -Lc %U:%G "$f") || exit 1
if [ "$o" = "root:root" ]; then echo compliant; else echo "noncompliant: $f $o"; fi

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Use chown to set file ownership of kubelet.conf to root:root
