Starting on March 12, 2025, OpenShift docs will only be available at docs.redhat.com. From that time on, docs.openshift.com links will automatically redirect to their locations on docs.redhat.com.
This documentation is a work in progress that aligns to preview releases of the next pending OpenShift Container Platform version 4 minor release. It might not be complete or fully tested, and some features and content might be removed before the next release. For the most recent released and supported version, see [4].
