The following table lists etcd support status for common architectures and operating systems,
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.
For etcd to officially support a new platform as stable, a few requirements are necessary to ensure acceptable quality:
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
