Version Revision History

About SUSE Manager Proxy 4.1

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/4.1/.

SUSE Manager Proxy Distribution

SUSE Manager Proxy 4.1 is provided through SUSE Customer Center and can be installed with the unified installer for SUSE Linux Enterprise 15 SP2. No separate SUSE Linux Enterprise subscription is required.

Installation and Setup

Installation of SUSE Manager Proxy 4.1 is done with the SUSE Manager Server 4.1 Web interface.

For more details on installing and configuring SUSE Manager Proxy 4.1, see the Installation Guide on https://documentation.suse.com/suma/4.1/.

Upgrade from Version 4.0

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

Upgrade from Version 3.2

To upgrade an existing SUSE Manager Proxy 3.2 system to SUSE Manager Proxy 4.1, 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/4.1/.

SUSE Manager Server Versions

SUSE Manager Proxy 4.1 works only with SUSE Manager 4.1 Server.

SUSE Manager Server 4.1 works with SUSE Manager Proxy 4.0 and later.

The combination of SUSE Manager 4.1 Server with SUSE Manager 3.2 Proxy or SUSE Manager 3.2 Retail Branch Server is not supported.

Major Changes Since SUSE Manager Proxy 4.0

New products enabled

  • SUSE Linux Enterprise Real Time 12 SP5

  • SUSE Linux Enterprise 15 SP2 family

  • openSUSE Leap 15.2

  • MicroFocus Open Enterprise Server 2018 SP2

  • CentOS 6, 7, and 8

  • Oracle Linux 6, 7 and 8

  • Ubuntu 20.04 LTS

CentOS

Starting with SUSE Manager 4.1, CentOS is supported as a client and shows in the product tree in the WebUI.

If you were using CentOS via spacewalk-common-channels, you will need to delete your existing channels, synchronize the channel information from SCC, and reassign the channels to the clients.

Oracle Linux

Starting with SUSE Manager 4.1, Oracle Linux is supported as a client and shows in the product tree in the WebUI.

Third-party GPG keys now included

Enabling verification of non-SUSE product metadata used to require manual acceptance, and sometimes even manual installation, of the third-party keys for products available from the product tree. Alternatively, an option to not verify the GPG key signature was there.

In addition to SUSE’s, SUSE Manager 4.1 now includes the GPG keys used to sign packages and/or metadata by other vendors whose products are available in the product tree in the WebUI:

  • openSUSE

  • CentOS

  • Oracle Linux

  • Ubuntu

  • MicroFocus Open Enterprise Server

Manual acceptance of those keys is no longer required for GPG signature verification for those products to work.

Manual acceptance of GPG keys for any other product or repository is still required for security reasons.

Proxy visibility in Systems Overview

SUSE Manager Proxy nodes are now included in the Systems Overview page, with system type "Proxy".

Salt 3000

Salt has been upgraded to the 3000 release for the SUSE Manager Server, Proxy, and Client Tools. As part of this upgrade, the cryptography is now managed by the Python-M2Crypto library (which is itself based on the well-known OpenSSL).

We intend to regularly upgrade Salt to more recent versions.

For more detail about changes in your manually-created Salt states, see the Salt upstream release notes 3000

Content Lifecycle Management filters for AppStreams

RHEL, SLES ES, CentOS and Oracle Linux 8 appstreams can now be mixed and converted to flat repositories using a new type of CLM filter.

New documentation guides

Two new books have been added to the SUSE Manager 4.1 documentation:

  • Large Deployments Guide. Everything related to architecture and configuration for large (thousands of clients) deployments is contained in this guide. It contains all the documentation for the SUSE Manager Hub component. Some parts of the Salt guide that dealt with parameter tuning for large deployments have now been moved here too.

  • Public Cloud QuickStart Guide. This new guide shows you the fastest way to get SUSE Manager up and running in a public cloud. It includes instructions for Amazon Web Services, Microsoft Azure, and Google Cloud Engine.

Also:

SLES 15 SP2 JeOS as a Base System

The SUSE Manager 4.1 Proxy and Retail Branch Server can now be installed on top of SLES 15 SP2 JeOS edition.

SUSE Manager for Retail

SLEPOS 15 SP2 clients

Pre-defined templates for SLEPOS 15 SP2 are now provided. SLEPOS 15 SP2 is supported for 7.5 years since the release date.

Small stores

Where a dedicated SUSE Manager Server or SUSE Manager Retail Branch Server is not feasible, it is now possible to use a Retail Branch Server running in a remote datacenter or public cloud.

Thanks to HTTP booting instead of PXE, branch servers no longer need to be on same physical network as the terminals.

EFI HTTP booting

The DHCP, branch network, and PXE formulas have been updated to support booting EFI terminals (systems) using HTTP in addition to TFTP.

Base System Upgrade

The base system was upgraded to SUSE Linux Enterprise 15 SP2.

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.
