Does anyone have examples of using Gitlab (or some other CI) to build multi-platform containers, in a way that doesn't seem to just QEMU the non-native part? https://docs.gitlab.com/ci/docker/using_buildkit/#build-multi-platform-images-in-rootless-mode to me reads like it will just do everything on whatever runner gets the job. But I have fast enough arm64 and fast enough amd64 and so my manual multi-platform builds do the work on the appropriate host. Of course, manual builds aren't a modern best practice.
