Support running external GUI apps via shared DISPLAY

[macosupdate]

Hi, thank you for the great base image.

I’d like to request a feature that allows other containers to connect to the X server via DISPLAY, similar to how theasp/novnc works (e.g., setting DISPLAY=gui:0 from another container).

This would enable running GUI apps in separate containers while sharing the same VNC/noVNC display backend. example https://github.com/theasp/docker-novnc

Thanks!

I don't think this feature should be implemented in the baseimage. The baseimage is designed to be tightly integrated with an application. I don't see that one would create a container for the application X, while wanting to accept X connection from another container.

I think what could make sense is to create a generic container (based on this baseimage) that would offer the wanted functionality.
