  ### Port Forwarding ###

  # Docker UI
  config.vm.network 'forwarded_port', guest: 9000, host: 9000

  # nsqlookupd
  config.vm.network 'forwarded_port', guest: 4160, host: 4160
  config.vm.network 'forwarded_port', guest: 4161, host: 4161

  # nsqd
  config.vm.network 'forwarded_port', guest: 4150, host: 4150
  config.vm.network 'forwarded_port', guest: 4151, host: 4151

  # nsqadmin
  config.vm.network 'forwarded_port', guest: 4171, host: 4171


  ### 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"
    d.run 'nsqd', image: 'nsqio/nsq', daemonize: true, cmd: "/nsqd -broadcast-address='#{DOCKER_IP}' -lookupd-tcp-address='#{DOCKER_IP}:4160' -data-path='/data'", args: "-p 4150:4150 -p 4151:4151 -v '#{APPS}/nsqd/data:/data'"
    d.run 'nsqadmin', image: 'nsqio/nsq', daemonize: true, cmd: "/nsqadmin -lookupd-http-address='#{DOCKER_IP}:4160' -http-address='0.0.0.0:4171'", args: "-p 4171:4171"
    d.run 'dockerui', image: 'crosbymichael/dockerui', daemonize: true, args: '-p 9000:9000 -v /var/run/docker.sock:/docker.sock crosbymichael/dockerui -e /docker.sock'
  end

end

This should give you four running docker containers, three of which for NSQ (nsqlookupd, nsqd, and nsqadmin). The other is the helpful dockerui image.

There are some docs available on the nsq.io site for docker if you feel like tweaking things more - http://nsq.io/deployment/docker.html

After a vagrant up, you should be able to go to http://localhost:9000 to verify all the containers are running and, if so, hit http://localhost:4171 to view the NSQ admin UI.

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.
