Dockerfile

# Ubuntu 15.04 with Java 8, IntelliJ Idea installed
# Build image with:
#   docker build -t elasticjava/idea:v1 .
#
# Idea need a few configuration step initially
#   so first start docker via
#    docker run -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v $PWD:/usr/local/src --net=host elasticjava/idea:v1
#   and configure IntelliJ your favourite way, install plugins etc. and quit the running Idea. Then conserve the running container as image with
#    docker commit $(docker ps -a -f ancestor=elasticjava/idea:v1 -n=1 -q) idea
#
# now you can run IntelliJ Idea inside your favourite source folder with:
#   docker run -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v $PWD:/usr/local/src --net=host idea

# !!! Replace "export uid=1000 gid=1000" with your user / group id
# do so by running
#   sed -i "s/export uid=1000 gid=1000/export uid=X$UID gid=X${GROUPS[0]}/" Dockerfile
# before interacting with this  Dockerfile
