Registering openSUSE Leap Micro Clients

This section contains information about registering clients running openSUSE Leap Micro operating systems on x86-64 and aarch64 architectures.

The openSUSE Leap Micro is an ultra-reliable, lightweight operating system purpose built for edge computing. It leverages the enterprise hardened security and compliance components of SUSE Linux Enterprise and merges them with a modern, immutable, developer-friendly OS platform.

The openSUSE Leap Micro uses transactional updates. Transactional updates are atomic (all updates are applied only if all updates succeed) and support rollbacks. They do not affect the running system because no changes are activated until the system is rebooted. This information is displayed in the Systems  Details  Overview subtab.

For more information on transactional updates and rebooting, see

Procedure: Adding Software Channels
  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard  Products.

  2. Locate the appropriate products for your client operating system and architecture using the search bar, and check the appropriate product. This will automatically check all mandatory channels. Also all recommended channels are checked as long as the include recommended toggle is turned on. Click the arrow to see the complete list of related products, and ensure that any extra products you require are checked.

  3. Click Add Products and wait until the products have finished synchronizing.

Alternatively, you can add channels at the command prompt. The channels you need for this procedure are:

openSUSE Leap Micro


Procedure: Adding Software Channels at the Command Prompt
  1. At the command prompt on the SUSE Manager Server, as root, use the mgr-sync command to add the appropriate channels:

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

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

1. Check Synchronization Status

Procedure: Checking Synchronization Progress from the Web UI
  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard and select the Products tab. This dialog displays a completion bar for each product when they are being synchronized.

  2. Alternatively, you can navigate to Software  Manage  Channels, then click the channel associated to the repository. Navigate to the Repositories tab, then click Sync and check Sync Status.

Procedure: Checking Synchronization Progress from the Command Prompt
  1. At the command prompt on the SUSE Manager Server, as root, use the tail command to check the synchronization log file:

    tail -f /var/log/rhn/reposync/<channel-label>.log
  2. Each child channel generates its own log during the synchronization progress. You need to check all the base and child channel log files to be sure that the synchronization is complete.

openSUSE Leap Micro channels can be very large. Synchronization can sometimes take several hours.

2. Register Clients

openSUSE Leap Micro clients require reboot after registering.

Following the bootstrapping process, automatic booting is disabled on openSUSE Leap Micro. This change was implemented due to intermittent automatic reboots, which could occurr before Salt could relay the results of applying the bootstrap salt state.

Reboot is automatically scheduled after registration is completed, but it is respecting the default reboot manager maintenance window. This window may be several hours after the client is registered. To speed up openSUSE Leap Micro registration, manually reboot the client after the registration script finishes.

To register your clients, you need a bootstrap repository. By default, bootstrap repositories are automatically created, and regenerated daily for all synchronized products. You can manually create the bootstrap repository from the command prompt, using this command:
