Dockerized Freemind - free mind mapping software, based on Alpine Linux, uses X11 socket

Requirements:

• Docker
• xhost (may be needed on some Linux distros)

How to:

• Build image
  docker build -t freemind .
  or
• Pull image from Docker Registry
  docker pull loadaverage/freemind
• Allow access to X server (for some Linux distros)
  xhost local:freemind
• Run own FreeMind image

docker run --rm \
     -v ~/Downloads/freemind:/home/freemind/Downloads \
     -v ~/.freemind:/home/freemind/.freemind/ \
     -v ~/.themes:/home/freemind/.themes:ro \
     -v ~/.fonts:/home/freemind/.fonts:ro \
     -v ~/.icons:/home/freemind/.icons:ro \
     -v /usr/share/themes:/usr/share/themes:ro \
     -v /usr/share/fonts:/usr/share/fonts:ro \
     -v /tmp/.X11-unix:/tmp/.X11-unix \
     -e DISPLAY=$DISPLAY freemind

• Run FreeMind image from Docker Registry

docker run --rm \
      -v ~/Downloads/freemind:/home/freemind/Downloads \
      -v ~/.freemind:/home/freemind/.freemind/ \
      -v ~/.themes:/home/freemind/.themes:ro \
      -v ~/.fonts:/home/freemind/.fonts:ro \
      -v ~/.icons:/home/freemind/.icons:ro \
      -v /usr/share/themes:/usr/share/themes:ro \
      -v /usr/share/fonts:/usr/share/fonts:ro \
      -v /tmp/.X11-unix:/tmp/.X11-unix \
      -e DISPLAY=$DISPLAY loadaverage/freemind

• Docker for Mac

Note: UNIX sockets in Docker for Mac are not yet supported, thus X11 network forwarding is the only way to go

• Allow access to the X11

export X11_IP=$(ifconfig en0 | grep '[i]net' | awk '$1 == "inet" {print $2}')
xhost +$X11_IP

or

• Use socat for UNIX socket -> TCP port forwarding

socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"

docker run --rm \
      -v ~/Downloads/freemind:/home/freemind/Downloads \
      -v ~/.freemind:/home/freemind/.freemind/ \
      -v ~/.fonts:/home/freemind/.fonts:ro \
      -e DISPLAY=$X11_IP:0 loadaverage/freemind

NOTES:

• Volumes: mounted config directories should have correct permissions, otherwise Freemind will not work properly
• Xhost: on Linux distros you may need explicitly allow access to X server through xhost command: xhost local:freemind
