Does anybody have other examples for Node.js, Python and Ruby?“

You can always refer to the official Docker Compose documentation for examples: https://docs.docker.com/compose/compose-file/

However DCHQ provides a lot of cool enhancements on Docker Compose like event-driven service discovery plug-ins and additional parameters like host, mem_min, registry_id, etc.

You can check out DCHQ's Docker Compose examples here: http://dchq.co/docker-compose.html#docker-compose-examples

Sure!
