Since the apps require a linux environment, docker does not run natively in Mac and PC. Rather, it sets up a linux virtual machine and runs docker engine inside that. Before version 1.12, docker on Mac required installation of virtualbox and docker-machine to manage this linux virtual machine inside which the containers are run. However, latest version of docker for mac uses hypervisor to run operating system as a service and thus has more native feel. Lets install it using Homebrew:

brew cask install docker

Run the app from the launcher and it will go through the initial setup process. We can now interact with the docker daemon through the shell.

Next, we will pull a debian image and install gimp and inkscape in it. Open a terminal and create a Dockerfile inside a folder called apps.

FROM debian:jessie
RUN apt-get update
RUN DEBIAN_FRONTEND=noninteractive \
  apt-get install -y -q gimp inkscape \
  ttf-dejavu --no-install-recommends
RUN rm -rf /var/lib/apt/lists/*
CMD "gimp"

Next, build the docker image called apps:

docker build -t apps .

docker commands

To run graphics inside docker containers, we will need X11 running on Mac. At the time of this writing the stable version of XQuartz (2.7.9) has a bug which prevents graphics forwarding. However, 2.7.10_beta2 works.

brew cask install xquartz-beta

The stable version of xquartz may work if it is higher than 2.7.10. Check the version in home-brew by: brew cask info quartz.

Start XQuartz and allow connections from network clients in preferences > security. Now the following commands should get gimp running:

ip=$(ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{print $2}')
xhost + $ip
docker run --rm -it -e DISPLAY=$ip:0 -v $HOME/Downloads:/root/Downloads apps

This will also share the ~/Downloads folder with the container. To run inkscape:

docker run --rm -it -e DISPLAY=$ip:0 -v $HOME/Downloads:/root/Downloads apps inkscape

Any changes made to gimp itself will be lost when the app is closed. Any additional plugins or customizations should be included in the Dockerfile to make them permanent.
