Procedure: Adding Software Channels at the Command Prompt
  1. At the command prompt on the SUSE Manager container host, as root, add the appropriate channels:

    mgrctl exec -ti -- mgr-sync add channel <channel_label_1>
    mgrctl exec -ti -- mgr-sync add channel <channel_label_2>
    mgrctl exec -ti -- mgr-sync add channel <channel_label_n>
  2. Synchronization starts automatically. If you want to synchronize the channels manually, use:

    mgrctl exec -ti -- mgr-sync sync --with-children <channel_name>
  3. Ensure the synchronization is complete before continuing.
