Building arm6 container image not working

[silverlyra]

Hey @jpkrohling – I’ve opened #55 which restores ARM64 image builds, and updates CI and CONTRIBUTING.md. The goreleaser CI check succeeded. 😊

Same for arm7:

And arm64 :(

Hi @jpkrohling – sorry, I didn’t see your ping! Didn’t realize this was a problem until I excitedly went to install v0.42 and discovered it’s still amd64 only. 😞

The build works fine on my machine:

❯ goreleaser --snapshot --rm-dist

arm64

I tried to find a failed GitHub Action with the output you pasted, but didn’t find one – is it just broken for you locally?

You may need to set up Docker buildx multi-arch builds in general. This is what I did on my (Arch (btw)) system:

yay -S qemu-headless binfmt-qemu-static qemu-user-static
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
docker buildx create --use

It did fail on GitHub as well: https://github.com/open-telemetry/opentelemetry-collector-releases/runs/4534427058?check_suite_focus=true

The buildx part might be decisive. I don't think I have it here, as I use podman. The CI probably doesn't use it either. If you could get the instructions on how to set it up locally and if you could configure the GH Actions to use buildx, we could add ARM back in time for 0.43.
