10 Post-deployment steps #
The chapter describes registration of SLE Micro and covers extensions available for SLE Micro.
10.1 Registration #
Registering the system is possible from the command line using the
transactional-update register
command. For information that goes beyond the scope
of this section, refer to the inline documentation with SUSEConnect
--help
To register SUSE Linux Enterprise Micro with SUSE Customer Center, run
transactional-update register
as follows:#
transactional-update register -r REGISTRATION_CODE -e EMAIL_ADDRESSTo register with a local registration server, additionally provide the URL to the server:
#
transactional-update register -r REGISTRATION_CODE -e EMAIL_ADDRESS \ --url "https://suse_register.example.com/"Replace REGISTRATION_CODE with the registration code you received with your copy of SUSE Linux Enterprise Micro. Replace EMAIL_ADDRESS with the e-mail address associated with the SUSE account you or your organization uses to manage subscriptions.
Reboot your system to switch to the latest snapshot.
SUSE Linux Enterprise Micro is now registered.
10.2 Managing extensions #
SLE Micro supports the following extensions:
SUSE Linux Enterprise Live Patching
The extension is available only for the x86 (except for the real-time kernel) and IBM Z architectures. Bear in mind that the extension might require an additional subscription.
Package Hub
A free module that provides access to community-maintained packages. Packages in the Package Hub are approved by SUSE for use on SUSE Linux Enterprise Server, thus the packages might not be installable on SLE Micro.
As the extension activation or deactivation is performed as a
transactional-update
command and thus creates a new snapshot, you need to restart
your system to boot to the new snapshot and apply the changes.
10.2.1 Activating extensions #
To activate an extension, proceed as follows:
List available extensions by running:
#
transactional-update --quiet register -list-extensionsThe output provides you with a command to activate the extensions, for example, for the
SUSE Linux Enterprise Live Patching
:#
transactional-update register -p sle-module-live-patching/15.4/x86_64 \ -r registration code
If you activated the SUSE Linux Enterprise Live Patching
extension, you need to perform additional steps as described below:
SUSE Linux Enterprise Live Patching
#Configure
libzypp
in the/etc/zypp/zypp.conf
file as follows:multiversion = provides:multiversion(kernel)
to keep the current kernel running while patching the system, otherwise you may get dependency conflicts while kernel updates are being applied.
multiversion.kernels = latest
after applying the live patch, a cleanup of kernels is performed in the new snapshot. If not set, the snapshot keeps the previous kernel and performs kernel updates also on the previous kernel.
Additionally, set
LIVEPATCH_KERNEL='always'
in the/etc/sysconfig/livepatching
file.Note: Matching version of thekernel-default-livepatch
and kernelto keep the current kernel running while patching the system, otherwise you may get dependency conflicts while kernel updates are being applied.
multiversion.kernels = latest
after applying the live patch, a cleanup of kernels is performed in the new snapshot. If not set, the snapshot keeps the previous kernel and performs kernel updates also on the previous kernel.
Additionally, set
LIVEPATCH_KERNEL='always'
in the/etc/sysconfig/livepatching
file.Note: Matching version of thekernel-default-livepatch
and kernelTo ensure that the live patches will be installed even after the kernel upgrade, install the matching version of the
kernel-default-livepatch
package.Now, install the extension by running:
#
transactional-update pkg install kernel-default-livepatchReboot your system to switch to the new snapshot.
10.2.2 Deactivating extensions #
To deactivate the extension, run the following command:
#
transactional-update register -d \
-p EXTENSION_NAME
For example, for the SUSE Linux Enterprise Live Patching
extension, the command is as follows:
#
transactional-update register -d \
-p sle-module-live-patching/15.4/x86_64
