Description

Ensure that the controller manager pod specification file ownership is set to root:root. The benchmark marks this recommendation Manual.

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.

OpenShift 4 deploys two controller managers: the OpenShift Controller manager and the Kube Controller manager. The OpenShift Controller manager is managed as a deployment. The pod specification yaml for openshift-controller-manager is stored in etcd. The Kube Controller manager is managed as a static pod. The pod specification file for the openshift-kube-controller-manager is created on control plane nodes at /etc/kubernetes/manifests/kube-controller-manager-pod.yaml.

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.
