  ### Port Forwarding ###

  config.vm.network 'forwarded_port', guest: 9000, host: 9000

  # nsqlookupd
  config.vm.network 'forwarded_port', guest: 4160, host: 4160

  # nsqadmin

  ### Shell Provisioning ###

  # install docker and configure vagrant user
  if Dir.glob("#{File.dirname(__FILE__)}/.vagrant/machines/default/*/id").empty?
    # Install Docker
    pkg_cmd = 'wget -q -O - https://get.docker.io/gpg | apt-key add -;' \
      'echo deb http://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list;' \
      'apt-get update -qq; apt-get install -q -y --force-yes lxc-docker; '
    # Add vagrant user to the docker group
    pkg_cmd << 'usermod -a -G docker vagrant; '
    config.vm.provision :shell, :inline => pkg_cmd
  end

  # setup shared directories for docker containers
  config.vm.provision 'shell' do |s|
    s.inline = "mkdir -p #{APPS}"
    s.inline = "mkdir -p #{APPS}/nsqd/data"
  end


  ### Docker Container Provisioning ###
  config.vm.provision 'docker' do |d|
    d.run 'nsqlookupd', image: 'nsqio/nsq', daemonize: true, cmd: "/nsqlookupd -broadcast-address='#{DOCKER_IP}'", args: "-p 4160:4160 -p 4161:4161"

  end

end

Note: I have only attempted to run this using the vagrant VMware plugin. It should work fine with VBox or on EC2, but you may need to adjust the file a bit.
