How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

In OpenShift 4, the kube-scheduler is deployed as a static pod and its pod specification file is created on control plane nodes at /etc/kubernetes/manifests/kube-scheduler-pod.yaml. It is mounted via hostpath to the kube-controller-manager pods via /etc/kubernetes/static-pod-resources/kube-scheduler-pod.yaml with ownership root:root. Run the following command.

How it is fixed

Fix method: Guidance or infrastructure patch

Execute the chown command to remediate ownership and set it file ownership to root:root.
