About SUSE Manager Proxy 4.3

SUSE Manager Proxy provides mirroring proxy support for large and distributed
environments.

Operation of the proxy is completely transparent. The SUSE Manager Proxy looks
like a managed client to SUSE Manager Server, and like a server to the managed
clients. Managed clients talk to the proxy only, and the proxy in turn
communicates to the SUSE Manager Server.

All software packages that pass the SUSE Manager Proxy are cached and
subsequent client requests for these packages are resolved from the cache.

Containerization

One goal that we want to achieve in a long run to enable SUSE Manager to be
deployed in container-only environments, independently from the base OS. Allow
SUSE Manager components (specifically Proxies/Retail Branch servers) to run in
more resource-constrained environments. Edge market is our main audience here
with this effort. It will allow users to install SUSE Manager components on top
of kubernetes, increasing flexibility and future viability

Enabling SUSE Manager Proxy 4.3 and Retail Branch Servers 4.3 to also run in
containers, is in scope of this release.

System requirements

SUSE Manager Proxy is available for x86_64 architecture only. We recommend you
have at least 8 GB main memory, and approximately 50 GB of disk space per
distribution or channel.

Consider additional disk space required for storing images for retail
terminals.

For more details on system requirements, see the Installation Guide on https://
documentation.suse.com/suma/4.3/.

SUSE Manager Proxy distribution

SUSE Manager Proxy 4.3 is provided through SUSE Customer Center and can be
installed with the unified installer for SUSE Linux Enterprise 15 SP4. No
separate SUSE Linux Enterprise subscription is required.

Installation and setup

Installation of SUSE Manager Proxy 4.3 is done with the SUSE Manager Server 4.3
Web interface.

For more details on installing and configuring SUSE Manager Proxy 4.3, see the
Installation Guide on https://documentation.suse.com/suma/4.3/.

Upgrade from previous version

To upgrade an existing SUSE Manager Proxy 4.1 or 4.2 system to SUSE Manager
Proxy 4.3, you can do an in-place upgrade, or you can set up a new system to
replace the old one.

For more information about upgrading, see the Upgrade Guide on https://
documentation.suse.com/suma/4.3/.

SUSE Manager Server versions

SUSE Manager Proxy 4.3 works only with SUSE Manager 4.3 Server.

SUSE Manager Server 4.3 works with SUSE Manager Proxy 4.1 and SUSE Manager
Proxy 4.2 but only for migration purposes. The product is not intended to be
used in a mixed-version scenario in production.

Features and changes

Major Changes Since SUSE Manager Proxy 4.2

Base System Upgrade

The base system was upgraded to SUSE Linux Enterprise 15 SP4.

Salt 3004

Salt has been upgraded to upstream version 3004, plus a number of patches,
backports and enhancements by SUSE, for the SUSE Manager Server, Proxy, Retail
Branch Server and Client Tools.

We intend to regularly upgrade Salt to more recent versions.

For more details about changes in your manually-created Salt states, see the
Salt 3004 upstream release notes.

Technology Preview: Containerized SUSE Manager Proxy and Retail Branch Server

Starting with SUSE Manager 4.3, it will be possible to run the SUSE Manager
proxy and Retail branch server also in containers. This could be very helpful
in scenarios where adding new virtual machines is not feasible for some reason.
Additionally, the ability to run SUSE Manager Proxy and Retail branch servers
in containers make it more flexible to run them anywhere without worrying about
the underlying OS. Moreover in the future, it will allow users to install SUSE
Manager components on top of Kubernetes, increasing flexibility and future
viability.

Migration from 4.1 and 4.2 to 4.3

It is now possible to migrate from 4.1 and 4.2 to 4.3. The user should upgrade
SUSE Manager Server and its related products i-e SUSE Manager Proxy and Retail
Branch Server as product is not meant to be run in a mixed-version scenario.
When upgrading, upgrade SUSE Manager Server first before upgrading SUSE Manager
Proxy or Retail Branch Server.

There is a known issue when migrating to 4.3, please consult the Known Issues
section for more detail.

Dropped features

None

Deprecated features

Traditional Stack has been deprecated

With SUSE Manager 4.3 release, traditional stack has been deprecated.

The release that follows SUSE Manager 4.3 will not support traditional clients
and traditional proxies, and is planned for 2023. We encourage all new
deployments to use Salt clients and Salt proxies exclusively, and to migrate
existing traditional clients and proxies to Salt.

Known issues

Migration from 4.1 and 4.2 to 4.3

SUSE Manager 4.3 is the base product for SLE15 SP4, this applies to Server,
Proxy, and Retail Branch Server. In SLE 15 SP4, sle-module-python2 is no longer
available (in favor of sle-module-python3). This means that migration(using
yast2 migration or zypper migration) from 4.1/4.2 to 4.3 will not work without
deactivating this module first. yast2 and zypper raise the following error if
the module is still activated during migration

Can't get available migrations from server: SUSE::Connect::ApiError: There are activated extensions/modules on this system that cannot be migrated.
Deactivate them first, and then try migrating again.
The product(s) are 'Python 2 Module 15 SP3 x86_64'.
You can deactivate them with:
SUSEConnect -d -p sle-module-python2/15.3/x86_64

As suggested in the error message one can deactivate the module using
SUSEConnect -d -p sle-module-python2/15.3/x86_64.

After this, migration should work.

Providing feedback

If you encounter a bug in any SUSE product, please report it through your SUSE
Customer Service or Sales representatives You can also provide feedback using
SUSE Manager discussion forum or the upstream Uyuni community
