This Dockerfile gives you an image with the latest RIDE pulled down from https://github.com/robotframework/RIDE ready to go.
In order to use it:
docker run -ti --rm \
-e DISPLAY=$DISPLAY \
-v /tmp/.X11-unix:/tmp/.X11-unix \
ride
and you should be up and running. You'll need an X server on the host, so it should work fine on Linux & OSX.
