docker nginx load balancing not working with Azure

Question

Ok been trying this setup for a full day now. I cannot get Nginx to connect the domain name that azure gave me to my node docker containers.

I'm using Azure to create a VM . The DNS name is scout-1j013s34.cloudapp.net The virtual IP address is 191.237.66.86

I can ssh into the VM with ssh monty@scout-1j013s34.cloudapp.net -p 61777 . I'm not sure why I need to specify a port?

The VM is running Ubuntu 14.04 . I installed docker myself.

I found and followed the following tutorial A sample Docker workflow with Nginx, Node.js and Redis

I built, and ran the containers as shown below.

Here is my nginx.conf file

worker_processes 4;

events { worker_connections 1024; }

http {

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;


    upstream node-app {
          least_conn;
          server node1:1337 weight=10 max_fails=3 fail_timeout=30s;
          server node2:1337 weight=10 max_fails=3 fail_timeout=30s;
          server node3:1337 weight=10 max_fails=3 fail_timeout=30s;
    }

    server {
          listen 80;

              server_name 191.237.66.86 scout-1j013s34.cloudapp.net www.scout-1j013s34.cloudapp.net;

          location / {
            proxy_pass http://node-app;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
          }
    }
}

when I enter http://scout-1j013s34.cloudapp.net/ into the browser address bar, it times out.

Update: I have EXPOSE 1337 in my Dockerfile to expose the 1337 ports for each node container.

For each node container I ran docker run -it --name node1 --link mongo:MONGODB -v /home/monty/scout/backend-api/:/scout-sails mlennie/scout-sails bash changing the name to node2 and node3 for the next 2 then I went into each container and started the sails.js app with sails lift .

Then I started the nginx container and linked it to the 3 node containers with the command docker run -d --name nginx -p 80:80 --link node1:node1 --link node2:node2 --link node3:node3 mlennie/nginx

好的，我可以正常工作了，我需要通过Azure管理门户手动添加一个端口为80的终结点。
