Chef Platform Support Policy

The purpose of this RFC is to clarify:

  • What specific operating system platforms and platform versions are supported by the software produced by Chef Software, Inc.
  • What is the meaning of "supported platform"

This RFC does not address "What is the product lifecycle of Chef Software, Inc.'s software". That is covered in a separate RFC.

Chef Client

A Chef Client supported platform means:

  • Omnitruck won't fail when confronted with the platform and version
  • The most important core resources (package, service, template) work out of the box
  • Ohai attributes for platform, platform_family, platform_version and kernel.machine are correct

Chef Client support policies also apply to Ohai, since that is a dependency.

Tier 1 Support

Tier 1 supported platforms are those for which Chef builds native binary "Omnitruck" (full-stack installer) packages. For each platform, Chef performs some post-build verification on them or their equivalents. For example, we may elect to do post-build verification for Oracle Enterprise Linux using the same test results as Red Hat Enterprise Linux, since they are so similar).

Platform Versions Architectures Package Format Built on
AIX 6.1, 7.1 ppc64 bff AIX 6.1
CentOS 5, 6, 7 i386, x86_64 rpm RHEL 5
FreeBSD 9, 10 i386, amd64 pkg_add pkg FreeBSD 9
Mac OS X 10.8, 10.9, 10.10 x86_64 dmg Mac OS 10.8
Oracle Enterprise Linux 5, 6, 7 i386, x86_64 rpm RHEL 5
Red Hat Enterprise Linux 5, 6, 7 i386, x86_64 rpm RHEL 5
Solaris 9, 10, 11 sparc, x86 shar Solaris 9
Windows 7, 8, 8.1, 2003R2, 2008, 2008R2, 2012, 2012R2 x86, x86_64 msi Windows 2008R2
Ubuntu Linux 10.04, 12.04, 14.04 x86, x86_64 deb Ubuntu 10.04

Tier 2 Support

Tier 2 supported platforms are those on which Omnitruck will serve packages, but those packages may not have been built on that OS variant. Additionally, we may or may not do post-build verification on these platforms.

  • SUSE Linux Enterprise Server 10, 11
  • Scientific Linux 5.x, 6.x and 7.x (i386 and x86-64)
  • Debian Linux 6.x and 7.x
  • Gentoo Linux (rolling release)
  • Arch Linux (rolling release)
  • Fedora (current non-EOL revisions)
  • OpenSUSE 12.3 (until EOL on 15 September 2014), 13.1
  • OmniOS stable and LTS releases

Not Supported

"Not supported" means there may be code in-tree, but we don't build for and test on those platforms. At our discretion, we may take patches that don't break any tier 1 or tier 2 platforms, but we have no way of testing these.

  • Solaris 8
  • AIX 5.1L
  • FreeBSD 8
  • OpenBSD
  • NetBSD
  • Windows 2003, Windows 2000
  • RHEL/CentOS/Oracle/Scientific 4.x or older
  • RHEL or SLES on POWER (ppc64) or System/z
  • HP-UX
  • Mac OS X < 10.8, anything ppc

Chef Server

Includes any of the add-ons (webui2/manage, push, etc.)

Supported

  • Ubuntu 10.04LTS, 12.04LTS, 14.04LTS
  • RHEL 5.x, 6.x, 7.x
  • CentOS 5.x, 6.x, 7.x
  • Oracle Enterprise Linux 5.x, 6.x, 7.x

Unsupported

  • Any other Linux or UNIX distributions
  • Windows

ChefDK

Supported

  • Windows 7, 8, 8.1
  • Fedora (current non-EOL releases)
  • RHEL 6.x
  • Mac OS X 10.8, 10.9, 10.10
  • Ubuntu 12.04, 14.04

ChefDK bundles Chef Client. Therefore, Chef Client is supported, by extension, on the foregoing client platforms, if not already mentioned explicitly in the Chef Client support matrix.

Unsupported

  • Windows Vista, XP, 2000
  • Mac OS X < 10.8, anything ppc

Appendix: Guiding Principles for Operating System Version Support

Once Chef Software, Inc. decides to support an operating system, we will also develop rules to determine under what upstream vendor lifecycle we will continue to support products, and they will be documented in this section. Vendors have various terminology to describe support lifecycles ('standard support', 'extended support', etc.) and it is useful to clarify what those mean in the context of Chef's products.
