build scala-native docker images on a mac

[FloWi]

Hi!

Just a follow up from the discussion at scalalove. I'm really impressed by the simplicity of scala-cli. Great work! I played around with it and created a docker-image. Turns out, this is the largest "hello world" so far ;-)

REPOSITORY                      TAG                            IMAGE ID       CREATED          SIZE
hello-docker                    latest                         f9ef14d6572d   59 seconds ago   435MB

I tried this command to maybe get a smaller image.

scala-cli package --docker HelloDocker.scala --docker-image-repository hello-docker --native

But I got this error message.

Package scala native application to docker image is not supported on MacOs and Windows

It would be cool to be able to create docker images with a scala-native binaries - even on a mac. Alex mentioned that it might work using the scala-cli docker image to build the native binary and use that to wrap it into another docker-container.
