Using Linux Display on OSX in docker

README.md

Installation

1. Install docker
2. Install socat (see install.sh)
3. Install XQuartz from https://www.xquartz.org

Running

1. Obtain your VirtualBox host IP Address. This is NOT the VirtualBox VM IP Address.

   $ VBOXNET=$(ifconfig vboxnet0 | grep inet | awk '{ print $2}')

2. Run XQuartz. (You may close the terminal)

3. Forward your display (socat MAY NOT fork() properly)

   $ socat TCP-LISTEN:6000,bind=${VBOXNET},reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"

4. Run your Linux GUI docker container (in a new window if socat does not fork())

   $ docker run -it --rm -e DISPLAY=${VBOXNET}:0 chrisdaish/firefox
