This is Andi's Docker Image for Ruby Development The Environment and User-Settings on this system is immutable and is maintained outside the container.
The path /home/developer/projects is supposed to be mounted via Docker to a hosted path outside the image
RVM is used to support your rubies and gemsets. ATTENTION!!! Changes to the RVM setup are immutable too. You will loose them on every logout! Instead of changing the RVM-Environment while you're logged in at the running image make your changes in the Dockerfile. The same is true for any setup in dot-files within the user's home-path.
Now run: "rake -T "
