Docker image containing Intellij Idea with Scala plugin and SBT

1. First time

   Build the image:

    docker build -t intellij-scala .
   

   If you are using OSX:

   ensure latest XQuartz is installed (for X11 forwarding of Intellij), then

     export IP=$(ifconfig en0 inet | grep inet | awk '{print $2'})
     export DISPLAY=${IP}:0.0
     open -a XQuartz
     xhost + $IP
   

   Run the container and mount useful volumes (1) your source code that you'll edit with intellij (2) the container's home directory so build artifacts are cached on host

    export CODE=/path/to/source/code/on/host # location of source code
    export WORKDIR=/code  # working-directory inside of container 
    export CACHE_DIR=${CODE}/intellij_cache
   
    docker run -it \
           -e DISPLAY=${DISPLAY} \
           -w ${WORKDIR} \
           -v ${CODE}:${WORKDIR} \                    (1)
           -v ${CACHE_DIR}:/home/developer \          (2)
           -v /tmp/.X11-unix:/tmp/.X11-unix \
           --name intellij \
           intellij-scala \
           /bin/bash
   

   Inside the container, install and run intellij or pycharm

    /opt/local/bin/install-intellij.sh
    /opt/local/bin/install-pycharm.sh
   
    now run pycharm or intellij via command line
   

2. The next time

   docker start intellij
