Without the --platform option, docker fails with "docker: no matching manifest for linux/amd64 in the manifest list entries". With the option, eveything works as intended.

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
