Mac OS X, Vagrant, Docker, Nginx, Node – how do ports play together?

I have a simple nginx, node.js setup that I want to migrate into the Vagrant, Docker world. I’m not sure how to handle IPs and ports.

My goal is it to see my Hello World in the Browser, best case on port 80, simply by calling my host

  • Docker not mapping port using gunicorn

    I found the solution myself – I created a simple boilerplate here:
    Feel free to go on from here.


    var app = express();
    app.route('*').all(function(req, res) {
      res.send('Hello World!');


    upstream {
      # using the vagrant private network IP (I guess?)
      # using the node port
    server {
      # ports nginx server is listen to
      listen 80;
      listen 443;
      location / {
        # upstream proxy
        # ...


    Vagrant.configure("2") do |config|
  = "ubuntu/trusty64"
      config.vm.provision "docker"
      # settimg a hostname that matches nginx upstream (I guess?)
      config.vm.hostname = ""
      # setting a private network IP, node.js and nginx run on this IP (i guess?) "private_network", ip: ""


      Vagrant.configure("2") do |config|
        config.vm.define "nginx" do |app|
          # forward the nginx port (I guess?)
 "forwarded_port", guest: 80, host: 80
          app.vm.provider "docker" do |d|
            d.build_dir  = "./docker/nginx"
            d.vagrant_vagrantfile = "./Vagrantfile.proxy"
        config.vm.define "node" do |app|
          # forward the node port (I guess?)
 "forwarded_port", guest: 2000, host: 2000
          app.vm.provider "docker" do |d|
            d.build_dir  = "./docker/node"
            d.vagrant_vagrantfile = "./Vagrantfile.proxy"


    # ...
    EXPOSE ["80"]


    # ...
    EXPOSE ["2000"]

    Mac OS X /etc/hosts

    I was expecting to call in the browser to see my Hello World via nginx and to see the node instance. Therefore the host does not work either.

    What do I do wrong?

  • Docker-Compose Issue with container name
  • ECS or EB for a single-container application with Docker?
  • Use Xcode with Docker (cross-compiling)
  • How to bind a port when using docker-py to create a service? [duplicate]
  • How to run a Shiny docker container on Alpine Linux?
  • Docker : initial installation script fails (ubuntu 13.04 , kernel 3.8+)
  • One Solution collect form web for “Mac OS X, Vagrant, Docker, Nginx, Node – how do ports play together?”

    I created the fork and made pull request to your repo.

    The main idea: do not use provisioning for docker containers.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
