Whisper Systems Signal Desktop in a container

To run this image, share the X11 socket or use any of the other methods to run X11 Apps in Docker.

For example, you can run the image like this on Linux. With this snippet in your ~/.bahsrc:

alias x_in_docker="docker run -d -u 1000:1000 --rm -e HOME \
  -e DISPLAY=unix:0 -e XAUTHORITY=/tmp/xauth \
  -v $XAUTHORITY:/tmp/xauth -v $HOME:$HOME \
  -v /etc/passwd:/etc/passwd:ro -v /etc/group:/etc/group:ro \
  -v /tmp/.X11-unix:/tmp/.X11-unix -w $HOME"
alias signal='x_in_docker kayvan/signal'

Launch the app by simply typing signal on your command line.

MacOS: Using this image

On MacOS, if you wish to run this image, you need to install XQuartz and socat. With brew installed, do this:

brew cask install xquartz
brew install socat

Then you can place this bash snippet in your ~/.bash_profile:

__my_ip=$(ifconfig|grep 'inet '|grep -v '127.0.0.1'| \
            head -1|awk '{print $2}')
signal() {
  killall -0 quartz-wm > /dev/null 2>&1
  if [ $? -ne 0 ]; then
    echo "ERROR: Quartz is not running. Start Quartz and try again."
  else
    socat TCP-LISTEN:6001,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\" &
    SOCAT_PGM_PID=$!
    docker run --rm \
      -e HOME \
      -e XAUTHORITY=/tmp/xauth -v ~/.Xauthority:/tmp/xauth \
      -e DISPLAY=$__my_ip:1 --net host -v $HOME:$HOME \
      ${1+"$@"} kayvan/signal
    kill $SOCAT_PGM_PID
  fi
}

Now, signal should launch the application.
