On: Crafting container images without Dockerfiles

> Also not sure how you build multi-arch containers.

not sure whether this is the preferred method or what, but i use `docker buildx` -- eg:

docker buildx build --tag myimage:mytag --platform linux/amd64,linux/arm64 .

this builds the image inside a qemu vm for the non-native architecture

Yes, that's what I use currently. I meant without docker/just with tar and friends.
