etcd runs on different platforms, but the guarantees it provides depends on a platform’s support tier:
The following table lists currently supported platforms and their corresponding etcd support tier:
|Architecture||Operating system||Support tier||Maintainers|
Unlisted platforms are unsupported.
Want to contribute to etcd as the “official” maintainer of a new platform? In addition to committing to support the platform, you must setup etcd continuous integration (CI) satisfying the following requirements, depending on the support tier:
|etcd continuous integration||Tier 1||Tier 2||Tier 3|
|Unit tests pass||✓||✓|
|Integration and end-to-end tests pass||✓||✓|
|Functional and stress tests pass||✓|
For an example of setting up tier-2 CI for ARM64, see etcd PR #12928.
To avoid inadvertently running an etcd server on an unsupported platform, etcd
prints a warning message and exits immediately unless the environment variable
ETCD_UNSUPPORTED_ARCH is set to the target architecture.
