# Getting X11 GUI applications to work on OS X with Docker

Install depedent packages via Brew (one-time setup)
```bash
$ brew install socat
$ brew cask install xquartz
```

Setup XQuartz

```bash
# optionally, stop xQuartz opening XTerm (I find this behavior annoying)
$ defaults write org.macosforge.xquartz.X11 nolisten_tcp 0
$ defaults write org.macosforge.xquartz.X11 app_to_run /usr/bin/true
```

Setup environment 
```bash
# setup using docker backed by virtualbox via DOCKER_HOST
$ eval $(docker-machine env) ; docker-machine ip

# start XQuartz session
$ open -a XQuartz

# Port forward x11 app (inside docker) request to XQuartz (on macos host)
$ socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"
```

Using X11 App
```bash
$ docker run --rm -e DISPLAY=$(docker-machine ip):0 [image] [command]

$ export DISPLAY=192.168.99.1:0   # <-- YMMV, default for docker-machine with virtualbox deployment

# chrome (testing secure CSA cluster, modified /etc/krb5.conf)
$ docker run \
  --rm \
  --name chrome \
  --net host \
  --volume "${HOME}/Downloads:/root/Downloads" \
  --volume "${HOME}/.config/google-chrome/:/data" \
  --security-opt seccomp:unconfined \
  --env "DISPLAY=192.168.99.1:0" \
