Development environment supported architectures

[rrhan0]

Is linux arm64 currently supported as a development environment?
CONTRIBUTING.md says only linux-amd64 is supported for development environments.

etcd/CONTRIBUTING.md

Line 85 in 7b2ad21

For both options, the only supported architecture is `linux-amd64`. Bug reports for other environments will generally be ignored. Supporting new environments requires the introduction of proper tests and maintainer support that is currently lacking in the etcd project.

but etcd.io docs say linux arm64 has tier 1 support.
https://etcd.io/docs/v3.7/op-guide/supported-platform/

Is there a difference between development environment and operations support? The last mention I found of this in a discussion was in 2023 #16404 (reply in thread)

Yes, those two pages are describing different kinds of support.

The supported-platform page is about building and running etcd. Linux/ARM64 is Tier 1 there, so release binaries and the project’s test coverage for that platform are officially supported.

CONTRIBUTING.md is narrower: it defines the environments the maintainers support for day-to-day contributor development, including the manual setup and the dev container. At the commit you linked, that policy still says Linux/AMD64 only and notes that environment-specific bug reports generally need to be reproduced there.

So native development on Linux/ARM64 may work — the repository has ARM64 build and test paths — but it is currently best-effort as a contributor environment. If you need the supported development setup on an ARM64 machine, the safe option is an AMD64 VM or container. The runtime support page does not, by itself, expand the development-environment policy in CONTRIBUTING.md.
