My boot2docker init adding port forwarding for all the cool services I use

boot2docker_init.sh

#!/usr/bin/env sh
if ! which boot2docker; then
  brew install boot2docker
  mkdir $HOME/.boot2docker
  echo DOCKER_PORT=32000 > $HOME/.boot2docker/profile
fi

if [[ -z $DOCKER_HOST ]]; then
  export DOCKER_HOST="tcp://127.0.0.1:32000"
  add_to_shell=1
fi

if boot2docker status | grep "does not exist"; then
  boot2docker init
elif boot2docker status; then
  echo "boot2docker already started; please stop before running"
  exit 1
fi

function add_boot2docker_port() {
  VBoxManage controlvm "boot2docker-vm" --natpf1 "tcp-port$1,tcp,127.0.0.1,$1,,$1";
  VBoxManage controlvm "boot2docker-vm" --natpf1 "udp-port$1,udp,127.0.0.1,$1,,$1";
}

VBoxManage modifyvm "boot2docker-vm" --cpus $(sysctl -n hw.ncpu)
VBoxManage modifyvm "boot2docker-vm" --memory "$(echo $(sysctl -n hw.memsize)/1024/1024*0.66/1 | bc)"
