Notes

The following command allows Docker to Spawn GUI apps on a local X Server:
This is EXTREMELY unsafe

xhost + local:

Group Issues

Runtime variables to declare

--group-add $(getent group audio | cut -d: -f3)
  • Fix sound issues when GID mappings do not line up with host (1000 [Ubuntu] compared to 985 [arch] for USER GID)*
  • Video/Audio groups might need to be added to fix this when specified in run/dockerfile (Audio is 995 [arch], Video is 986 [arch])*

Audio Issues

If host is using ALSA, then containers can use containerized pulseaudio (Jess's Files)

If host is using PulseAudio (Ubuntu) then add these lines to docker run to make containers share HOST pulseaudio:

-v ${XDG_RUNTIME_DIR}/pulse/native:${XDG_RUNTIME_DIR}/pulse/native:Z
-e PULSE_SERVER=unix:${XDG_RUNTIME_DIR}/pulse/native
--group-add $(getent group audio | cut -d: -f3)

Dockerfile builds

dDebug

Container full of Debug tools

Xephyr

Xephyr is a nested X server that runs as an X application
https://wiki.archlinux.org/index.php/Xephyr

This is my favorite way of using a container like a full blown virtual machine. Refer to the README, using Kali as an example.
