A wrapper shell script to use a virtualbox image for running the docker daemon on MacOS, uses docker-machine

dkr

#!/bin/bash
if ! [ -x "$(command -v docker-machine)" ]; then
  echo 'docker-machine not installed'
  brew install docker-machine
fi
if ! [ -x "$(command -v docker)" ]; then
  echo 'docker client not installed'
  brew install docker
fi

if ! docker-machine ls -q | grep -q 'vb-box'; then
  echo 'creating machine'
  docker-machine create -d virtualbox vb-box
  echo 'machine created'
fi

if ! docker-machine status vb-box | grep -q 'Running'; then
   echo 'starting vb-box'
   docker-machine start vb-box
   echo 'vb-box started'
fi
eval $(docker-machine env vb-box)

if [ $1 = "halt" ]; then
  echo "halting"
  docker-machine stop vb-box
else
   docker $@
fi
