Supported systems

Current support

The following table lists etcd support status for common architectures and operating systems:

Architecture Operating System Status Maintainers
amd64 Darwin Experimental etcd maintainers
amd64 Linux Stable etcd maintainers
amd64 Windows Experimental
arm64 Linux Experimental @glevand
arm Linux Unstable
386 Linux Unstable
ppc64le Linux Stable etcd maintainers, @mkumatag

Experimental platforms appear to work in practice and have some platform specific code in etcd, but do not fully conform to the stable support policy. Unstable platforms have been lightly tested, but less than experimental. Unlisted architecture and operating system pairs are currently unsupported; caveat emptor.

Supporting a new system platform

For etcd to officially support a new platform as stable, a few requirements are necessary to ensure acceptable quality:

  1. An "official" maintainer for the platform with clear motivation; someone must be responsible for taking care of the platform.
  2. Set up CI for build; etcd must compile.
  3. Set up CI for running unit tests; etcd must pass simple tests.
  4. Set up CI (TravisCI, SemaphoreCI or Jenkins) for running integration tests; etcd must pass intensive tests.
  5. (Optional) Set up a functional testing cluster; an etcd cluster should survive stress testing.

32-bit and other unsupported systems

etcd has known issues on 32-bit systems due to a bug in the Go runtime. See the Go issue and atomic package for more information.

To avoid inadvertently running a possibly unstable etcd server, etcd on unstable or unsupported architectures will print a warning message and immediately exit if the environment variable ETCD_UNSUPPORTED_ARCH is not set to the target architecture.

Currently amd64 and ppc64le architectures are officially supported by etcd.
