Ensure that the etcd data directory ownership is set to root:root

HighLevel 1Manual reviewopenshift

Description

Ensure that the etcd data directory 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, etcd members are deployed on the master nodes as static pods. The etcd database is stored on the master nodes in /var/lib/etcd and mounted to the etcd-member container via the host path mount data-dir with the same filesystem path (/var/lib/etcd). The ownership for this directory on the etcd-member container and on the container host is root:root. Starting with OCP 4.4, etcd is managed by the cluster-etcd-operator. The etcd operator will help to automate restoration of master nodes. There is also a new etcdctl container in the etcd static pod for quick debugging.

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.
