A bridge operator asked us to cross-compile our docker image for arm64. This sounds like an easy-ish fix that would make the lifes of our bridge operators easier. Let's figure out what it takes to support ARM and potentially other architectures.

On Linux, cross-architecture builds for docker are currently still an experimental feature that's provided by the "buildx" module. I'll briefly summarise how I got this module to run.

On my Debian buster, I installed the docker-ce-cli package and linked the module /usr/libexec/docker/cli-plugins/docker-buildx to ~/.docker/cli-plugins/docker-buildx. I then enabled experimental features by writing the following to the file /etc/docker/daemon.json:

    "experimental": true                                                         

Next, I restarted the docker service by running sudo service docker restart. Finally, I had to export the environment variable DOCKER_CLI_EXPERIMENTAL=enabled. Once all of that was done, I was able to use experimental features:

$ docker version -f '{{.Server.Experimental}}'

...and in particular, the buildx plugin. I stumbled upon a useful blog post that provides an overview of this process.
