Supported platforms

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

• etcd-maintainers are listed in https://github.com/coreos/etcd/blob/master/MAINTAINERS.

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 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 only the amd64 architecture is officially supported by etcd.
