Ensure that the etcd pod specification file ownership is set to root:root

HighLevel 1Manual reviewopenshift

Description

Ensure that the /etc/kubernetes/manifests/etcd.yaml 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.

In OpenShift 4, starting with OpenShift 4.4, the etcd pod specification file is generated by the cluster etcd operator. The pod specification file is created on control plane nodes at /etc/kubernetes/manifests/etcd-member.yaml with ownership root:root. The default etcd pod specification file is available here: openshift/cluster-etcd-operator Run the following command : #Verify openshift-etcd ownership for i in $(oc get pods -n openshift-etcd -l app=etcd -o name | grep etcd ) do echo "check pod $i" oc rsh -n openshift-etcd $i \ stat -c %U:%G /etc/kubernetes/manifests/etcd-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.
