--------------------------------------
Hi [~wwei], as [~wilfreds] mentioned, it's not necessary to have a new
environment to build multi-arch images. However, I think it's important to
clarify some points:
* Currently the binaries are compiled before the images (not in the same
Dockerfile), so in the docker build process it only copies the binary inside
the image.
* With docker buildx, using a single dockerfile you get a multi-arch image,
supporting multiple platforms {*}with the same tag{*}.
* If the idea is to keep generating the binaries by cross-compiling with go
you would need to have different dockerfiles for each architecture and in order
to get multi-arch images you would need to unify them by using docker manifest.
This
[post|https://www.docker.com/blog/multi-arch-build-and-images-the-simple-way/]
explains the different approaches.
I have
[experience|https://github.com/grycap/oscar/blob/master/.github/workflows/main.yaml#L27]
working with docker buildx compiling the binaries within the image creation
process (it can be done on another stage), but it is true that the building is
slower since it uses qemu to emulate the different architectures. Moreover,
cross-compiling with go is faster, but creating a multi-arch image is more
tedious. So I think the first step is to decide which approach to use.

> It would be good to support arm64, this is probably not too painful and can
> be done by swapping docker build with docker buildx, but there's often edge
