Cool.

I recently needed to look into how to cross-build images, and it’s through buildx. Specifically, for my case, I needed to ensure that I was building a linux/amd64 version:

sh
docker buildx build --platform linux/amd64 -t $(IMAGE) . --load

If you change that to something like:

sh
docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v6 …

Then you should automatically get a multi-arch image. There’s more to it than just that, and I’ve only scratched the surface of it, but it is impressive.
