Registering SLE Micro Clients

This section contains information about registering clients running these  SLE Micro operating systems:

  • SLE Micro 5.1 x86-64

  • SLE Micro 5.1 ARM64

Support for SLE Micro clients is provided as a technology preview for testing purposes, and not all features are fully functional at this stage. This feature is expected to be fully supported in a later version of Uyuni. Do not use this feature on production systems.

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

For more information on transactional updates, see https://documentation.suse.com/sles/15-SP3/html/SLES-all/cha-transactional-updates.html

When you install from a DVD or ISO image, salt-transactional-update and the dependencies such as Salt and python3 are not installed. These packages are required to register a SLE Micro client to Uyuni. On the client, before registering it, run as root:

transactional-update pkg install salt-transactional-update

1. Add Software Channels

Before you register SLE Micro clients to your Uyuni Server, you need to add the required software channels, and synchronize them.

In the following section, descriptions often default to the x86_64 architecture. Replace it with other architectures if appropriate.

2. Check Synchronization Status

Procedure: Checking Synchronization Progress from the Web UI

  1. In the Uyuni Web UI, navigate to Software  Manage  Channels, then click the channel associated to the repository.

  2. 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 Uyuni 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.
