bash function to automatically ensure the boot2docker environment is up and running on OSX

docker-init

#!/bin/bash

# start boot2docker and shellinit automatically
DOCKER_RUN=`which docker`
docker(){
        if ! /Applications/VirtualBox.app/Contents/MacOS/VBoxManage list runningvms | grep boot2docker-vm >/dev/null ; then
                boot2docker start
        fi
        if [ "$DOCKER_HOST" == "" ]; then
                $(boot2docker shellinit)
        fi
        $DOCKER_RUN $@
}

Basically just wraps the docker command. Just use docker as normal and this will ensure the environment is set up.

Thanks Adam!
