This doesn't work either:

$ docker run --rm -t --platform linux/arm64v8 arm64v8/ubuntu uname -m
Unable to find image 'arm64v8/ubuntu:latest' locally
latest: Pulling from arm64v8/ubuntu
docker: no matching manifest for linux/arm64v8 in the manifest list entries.
See 'docker run --help'.

After changing the --platform to just arm64 it "works" as intended:

$ docker run --rm -t --platform linux/arm64 arm64v8/ubuntu uname -m
Unable to find image 'arm64v8/ubuntu:latest' locally
latest: Pulling from arm64v8/ubuntu

It works on many architectures and OS container images.
