For docker this gives:

 ERROR: docker: 'docker buildx build' requires 1 argument                                                                                                                      
 Usage:  docker buildx build [OPTIONS] PATH | URL | -

I think it expects a . or - since the dockerfile is passed with -f
below. Going back to

  docker=$script_dir/../tests/docker/docker.py

makes it work.
