Mac OS X, Vagrant, Docker, Nginx, Node - how do ports play together? - node.js

Question

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 http://example.com.
UPDATE
I found the solution myself - I created a simple boilerplate here:

Feel free to go on from here.
app.js
var app = express();
app.route('*').all(function(req, res) {
res.send('Hello World!');
});
app.listen(2000)
nginx.conf
upstream example.com {
# using the vagrant private network IP (I guess?)
# using the node port
server 192.168.33.10:2000
}
server {
# ports nginx server is listen to
listen 80;
listen 443;
location / {
# upstream proxy
proxy_pass http://example.com;
# ...
}
}
Vagrantfile.proxy
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/trusty64"
config.vm.provision "docker"
# settimg a hostname that matches nginx upstream (I guess?)
config.vm.hostname = "example.com"
# setting a private network IP, node.js and nginx run on this IP (i guess?)
config.vm.network "private_network", ip: "192.168.33.10"
end
Vagrantfile
Vagrant.configure("2") do |config|
config.vm.define "nginx" do |app|
# forward the nginx port (I guess?)
app.vm.network "forwarded_port", guest: 80, host: 80
app.vm.provider "docker" do |d|
d.build_dir = "./docker/nginx"
d.vagrant_vagrantfile = "./Vagrantfile.proxy"
end
end
config.vm.define "node" do |app|
# forward the node port (I guess?)
app.vm.network "forwarded_port", guest: 2000, host: 2000
app.vm.provider "docker" do |d|
d.build_dir = "./docker/node"
d.vagrant_vagrantfile = "./Vagrantfile.proxy"
end
end
end
/nginx/Dockerfile
# ...
EXPOSE ["80"]
/node/Dockerfile
# ...
EXPOSE ["2000"]
Mac OS X /etc/hosts
192.168.33.10 example.com
I was expecting to call http://192.168.33.10 in the browser to see my Hello World via nginx and http://192.168.33.10:2000 to see the node instance. Therefore the host example.com does not work either.
What do I do wrong?

I created the fork and made pull request to your repo.
The main idea: do not use provisioning for docker containers.
