[erlang-questions] Making a minimal distributable program in Erlang.

[Stu Bailey]

"As an afterthought - it would be *very nice* to have a program which
makes a minimal distributable program for Windows/Mac/Linux."

Joe,

It would be nice if Erlang had an official Docker image (e.g.
https://docs.docker.com/docker-for-windows/ ).  Such an image would fulfill
exactly your requirement. Here are the official Docker images for other
languagesl:

https://hub.docker.com/_/python/
https://hub.docker.com/_/golang/
https://hub.docker.com/_/rust/
https://hub.docker.com/_/clojure/
https://hub.docker.com/_/java/

I guess this is the start:

https://github.com/erlang/docker-erlang

Note this work:
