Red Hat Offline Knowledge Portal: All the Docs, Air-Gapped, On Your Laptop

The entire Red Hat documentation site and the full Knowledgebase fit into a single OCI container that updates weekly, runs locally with a web UI and Solr search, and is included in every RHEL subscription that bundles Satellite. I have it on my laptop. I use it daily. Almost nobody I talk to knows it exists. This post is my small contribution to fixing that.
