The problem it creates is docker manifest create, which we use: it can't work with manifests (maybe we can make it work in v29 though?)

INFO:__main__:Creating manifest for tag: quay.io/jupyter/docker-stacks-foundation:conda-25.9.1
quay.io/jupyter/docker-stacks-foundation:aarch64-conda-25.9.1 is a manifest list

The command which was run is: docker manifest create quay.io/jupyter/docker-stacks-foundation:conda-25.9.1 quay.io/jupyter/docker-stacks-foundation:aarch64-conda-25.9.1 quay.io/jupyter/docker-stacks-foundation:x86_64-conda-25.9.1

When inspecting old single-platform images using docker inspect it was giving lots of layers, now it gives a list of 2 manifests.

Are you a maintainer?

I think if we start using https://docs.docker.com/reference/cli/docker/buildx/imagetools/create/#annotation, we should be fine
