I will assume you mean xpra here.
What sort of graphics? This an X11 application, right?

I'm not 100% certain I understand what you're trying to do, but if you
cannot install xpra in the container whose applications you are trying
to expose, you can install xpra in another container and then start your
applications on the display started by the xpra server there. ie:
DISPLAY=xpraserverIP:DISPLAYNO yourapp
You will need to allow TCP connections to your X11 server, see xhost and
remove "-nolisten tcp" from xpra's default xvfb command.
If you don't want to expose the X11 display over plain TCP, you can use
ssh display forwarding between the two containers.
In any case, there are benefits to this approach: you can really isolate
your application by running it in a container with very limited network
access.

Cheers,
Antoine
