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
Beta 3 release
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, while also making it possible to get the advantage of Kubernetes offerings like HA.
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.

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_64As 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.

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
