GL650 updated to cover Red Hat Satellite 6.19 with RHEL 10 managed hosts

Guru Labs is pleased to announce the release of our updated GL650 Red Hat Satellite v6 Administration (Foreman/Katello) course. It now covers Red Hat Satellite 6.19 with RHEL 10 managed hosts. The course has grown to five days of material, with 31 hands-on labs. Major new topics include image mode (bootc) hosts and Leapp upgrades from RHEL 9 to RHEL 10. Remote execution now runs in pull mode as well as over SSH, and webhooks send Satellite events to other systems. Content management covers rolling content views and multiple content view environments per host. Configuration management is taught with Ansible roles.

GL650 is the most current Red Hat Satellite training available. RH403 Red Hat Satellite 6 Administration, the course from Red Hat, is still based on Satellite 6.15, according to the RH403 course page as of this writing. RH403 runs on RHEL 8. Satellite 6.15 was released on April 23, 2024. Red Hat ended maintenance support for it on November 30, 2025.

Satellite 6.16 through 6.19 added or changed the features below. GL650 teaches each of them:

The chapters follow the order a team builds out a Satellite:

The later labs build on the earlier ones. In the IdM chapter, students install a Red Hat Identity Management server. The provisioning labs then boot a blank machine over PXE, and Discovery picks it up. Once provisioned, it enrolls in IdM and runs its Ansible roles on first boot. In the last chapter, students deploy a Capsule for a remote site and provision a host through it. They also export content to a disconnected organization with Inter-Satellite Sync.

The labs use Foreman 3.18 and Katello 4.20. Those are the upstream releases behind Satellite 6.19. Where Satellite and upstream differ (installer and maintain command names, package names, manifests, Red Hat repositories, Lightspeed), the course covers both.

Guru Labs takes an active role in improving the open source software it teaches. While updating GL650, we found the bugs below, fixed them, and submitted the fixes upstream. The classroom environment runs the fixed versions, so the labs work smoothly and without errors.

As a fix ships in a Foreman, Katello or Leapp data release, the classroom moves to the released package. Students learn the procedure the way it is meant to work, and the same fixes reach teams that run Foreman, Katello or Satellite.

Two guides came out of the same research. Red Hat Satellite Best Practices: Avoiding Common Pitfalls covers the design and operating mistakes that cause most Satellite trouble. The Red Hat Satellite Upgrade Checklist lists the checks to clear before the first hop, the commands for every hop, and what changes in 6.17, 6.18 and 6.19.

GL650 Red Hat Satellite v6 Administration (Foreman/Katello) is a five-day course. The topics above are chapters or labs in it.
