Supported Operating Systems

Before implementing Salt to manage any data center infrastructure it is important to understand a few things about Salt platform support including: What platforms will the Salt Master run on? What systems and infrastructure can be managed by a Salt Minion? Salt runs on and manages many versions of Linux, Windows, Mac OS X and UNIX. The Salt Supported Operating System document defines the specific operating systems that are fully supported  and outlines the package creation policy for each operating system listed. The document also outlines the best-effort support policy for additional operating systems.

The Salt Support Operating System guidelines, in addition to the Salt product lifecycle phases and definitions listed below, are intended to clearly define how long a particular operating system and Salt version will receive official packages, testing, and technical support.

Support Life Cycle Phase Definitions

Phase 1: Regular point release support
During phase 1, Salt Project will issue regular point releases with critical bug fixes. Improved software functionality may be provided at the discretion of the project. Point releases will include the content of previously released updates. The focus of phase 1 releases will be high and critical bugs.

Phase 2: On-demand support
During phase 2, Salt Project may release point releases with bug fixes as requested by SaltStack customers. Point releases will include the content of previously released updates. The focus of phase 2 releases will be high or critical bugs.

Phase 3: CVE support
During phase 3, Salt Project will release point releases with fixes for selected, critical CVEs. Fixes in newer branches will not be back ported.

Extended life support
During extended life support, Salt Project will not release any point releases. Users will still have access to any documentation. Salt Project will provide ongoing best-effort technical support for customers on existing installations. No bug fixes, security fixes, improved functionality, or root-cause analysis will be provided.
