[Feature Request] Multiarch docker builds

[m1k1o]

Right now, only amd64 images are being built. It would be great, to have multiarch builds.

Taken from #93.

AFAIK GitHub does not provide ARM based runner, it needs to be self hosted.

I'm a bit late with this one

It does not but with docker you don't need one. You can use docker buildx to build for many architectures.
Example: microsoft/azure-pipelines-tasks#12035

This is how I do it with one of my projects:

Note --platforms, it reads from .env a list of them.

There is already attempt for some arm64 images, but not all apps support that:
