Overrides the docker command and ensures that the default docker-machine is running before running the actual docker command

.bash_profile_docker

function docker() {
  if [ `docker-machine status default` != "Running" ]; then
    echo "WARNING! Starting Default Docker Machine."
    
    docker-machine start default | logger
    eval "$(docker-machine env default)"
  fi 
  
  command docker $@
}
