About SUSE Manager Proxy 4.2

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.

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/4.2/.

SUSE Manager Proxy distribution

SUSE Manager Proxy 4.2 is provided through SUSE Customer Center and can be installed with the unified installer for SUSE Linux Enterprise 15 SP3.

Installation and setup

Installation of SUSE Manager Proxy 4.2 is done with the SUSE Manager Server 4.2 Web interface.

For more details on installing and configuring SUSE Manager Proxy 4.2, see the Installation Guide on https://documentation.suse.com/suma/4.2/.

Upgrade from previous version

To upgrade an existing SUSE Manager Proxy 4.1 or 4.0 system to SUSE Manager Proxy 4.2, 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/4.2/.

SUSE Manager Server versions

SUSE Manager Proxy 4.2 works only with SUSE Manager 4.2 Server.

SUSE Manager Server 4.2 works with SUSE Manager Proxy 4.0 and SUSE Manager Proxy 4.1 but only for migration purposes. The product is not intended to be used in a mixed-version scenario in production.

Major changes since SUSE Manager Proxy 4.2 GA

Features and changes

Version 4.2.4

New product enabled

  • SUSE Linux Enterprise Server 15 SP2 LTSS

CentOS 8 support

CentOS 8 will be End of Life on 31st December 2021, and with that the SUSE Manager support for this product will end as well.

Please refer to support section for more information.

Monitoring - Prometheus Blackbox exporter

SUSE Manager 4.2.4 comes with the Blackbox exporter, which allows blackbox probing of endpoints over HTTP, HTTPS, DNS, TCP, and ICMP. Please note that it needs to be installed next to the Prometheus server and not on the clients. Prometheus formula has been extended to configure blackbox exporter.

The package prometheus-blackbox_exporter has been added as recommended for the Proxy.

Version 4.2.3

Monitoring Formulas

One of the limitations of the current formulas is that they are listed against every client, even if the supported packages are not available for that OS version or service pack. While we are continuously focused on improving the formulas, for now, starting with the monitoring formulas it will be mentioned in docs if applying those formulas would actually work in the case of a particular client.

In 4.2.2, we made the Prometheus package available for SUSE Manager Proxy and Retail Branch Server but that is not the case with Grafana.

  • Prometheus is available for the client tools for SLE12/SLE15/openSUSE15/SUSE Manager proxy/Retail Branch Server

  • Grafana is available for the client tools for SLE12/SLE15/openSUSE15

Version 4.2.2

Prometheus available for SUSE Manager Proxy and Retail Branch Server

From this version, the Prometheus package will also be available for SUSE Manager Proxy and Retail Branch Server. In case you plan to use the branch server or proxy as a monitoring server with Prometheus, be aware that Prometheus demands additional hardware resources.

Ansible

The Ansible package will also be available for SUSE Manager Proxy and Retail Branch Server, which makes it possible to use SUSE Manager Proxy and Retail Branch Server as Ansible control Node.

When making SUSE Manager Proxy or Retail Branch Server an Ansible control Node, the extra load can affect the performance of this critical component. Bad performance of the Branch Server can further affect attached clients.

Version 4.2.1

Major Changes Since SUSE Manager Proxy 4.1

Salt 3002

Salt has been upgraded to upstream version 3002, plus a number of patches, backports and enhancements by SUSE, for the SUSE Manager Server, Proxy and Client Tools (where the client operating system supports Python 3.5+; otherwise Salt 3000 or 2016.11 are used).

We intend to regularly upgrade Salt to more recent versions.

For more details about changes in your manually-created Salt states, see the Salt 3002 upstream release notes.

SLES 15 SP3 JeOS as a Base System

The SUSE Manager 4.1 Proxy and Retail Branch Server can now be installed on top of SLES 15 SP3 JeOS edition.

Base System Upgrade

The base system was upgraded to SUSE Linux Enterprise 15 SP3.

Known issues

Proxy password

Do not use the '@' character in the SUSE Manager Proxy password, as it is not escaped correctly.

Single Sign On, API and CLI tools

Single Sign On can be used to authenticate in the Web UI but not with the API or CLI tools. This will be fixed in a future release of SUSE Manager.

Support

Support for CentOS 8

CentOS 8 will be End of Life on 31st December 2021, ending the SUSE Manager support for this product as well.

We recommend you to migrate your workload to CentOS 8 alternatives (AlmaLinux 8, Rocky Linux 8) as soon as possible so you can continue managing your infrastructure with SUSE Manager.

Please note "end of support" from the SUSE Manager side means these products and their client tools remain available in the SUSE Manager product tree and can still be added, mirrored and used. But in case they stop working at some point in time, support will only be provided as on a best-effort basis (which in general means if the issue can be reproduced with a supported operating system, it will be fixed; but if the issue is specific to the unsupported operating system, a fix should not be expected).

Future deprecation of the traditional stack

This version of SUSE Manager is compatible with Salt and traditional clients. SUSE will deprecate traditional clients and traditional proxies in the next SUSE Manager 4.3 release. 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.

If you encounter a bug in any SUSE product, please report it through your SUSE Customer Service or Sales representatives.
