Wat het doet

rhc (Remote Host Configuration) is the simple registration client of RHEL. rhc connect registers the system with Red Hat Subscription Management (so dnf gets the BaseOS and AppStream repositories), turns on Red Hat Lightspeed (the service that was called Red Hat Insights) and connects the system to the Hybrid Cloud Console at console.redhat.com for remote tasks. Each part can be turned off with --disable-feature.

Use an activation key and the organization ID for scripts and many systems; a user name and password for a single test machine.

Let op

  • The organization ID and activation key can register systems to your account. Keep them out of public repositories.
  • rhc is only for systems that connect directly to Red Hat. With Red Hat Satellite, use subscription-manager.

Tips om te onthouden

  • Kickstart also has its own rhsm --organization=ID --activation-key=KEY command for registration during the installation.

Exitcodes
