These are a collection of my dockerfiles. Most are X based for now, as that is the area which is giving me the most interest.

X11 and Docker

To forward X11 through docker efficiently, all you need to do is set the DISPLAY environment to unix:(your host DISPLAY) and share the host filesystem socket (ex. /tmp/.X11-unix/X0). This can be done in most cases with:

Host:

sudo docker run -rm -v /tmp/.X11-unix/:/tmp/.X11-unix/ -i -t fedora /bin/bash

Container:

export DISPLAY=unix:0

-v is for volume mapping and can be invoked multiple times for the same container. Sound can also be forwarded this way through sharing Pulseaudio sockets (and setting PULSE_SERVER on the container to point at the socket.)
