Multi-Arch docker images

[torfbolt]

It would be great if the automatic docker build process could be expanded for multi-arch images, something like this:
https://www.docker.com/blog/multi-arch-images/

This way people with ARM machines could use the latest client versions and help testing the bleeding edge.

We're providing precompiled binaries with every release starting with tag v0.3.2.

Building ARM images should work with the following command

bazel run --config=release --config=linux_arm64_docker //beacon-chain:image_bundle

[prestonvanloon]

Actually, I just tried the above command and the result was

ERROR: /home/preston/git/prysm/tools/BUILD.bazel:41:1: PackageTar tools/passwd_tar.tar failed (Exit 127) build_tar failed: error executing command bazel-out/host/bin/external/bazel_tools/tools/build_defs/pkg/build_tar --flagfile bazel-out/aarch64-fastbuild/bin/tools/passwd_tar.args

Use --sandbox_debug to see verbose messages from the sandbox
/usr/bin/env: 'python': No such file or directory
Target //beacon-chain:image_bundle failed to build

In any case, you could copy the release files into an ARM64 based image and that would satisfy the use case I think.

I'll leave this open now to consider adding this automatically in our continuous integration pipeline.

@torfbolt we provide multiarch binaries now as a recommended installation for ARM.

I'll close this for now, thanks for the report!

Edit: see https://docs.prylabs.network/docs/install/arm/

Revisiting this issue to properly provide multiarch docker images.
