Nginx + docker set up a reverseproxy with dockers nameserver

If you loadbalance 2 or more nginx containers you will need to use dockers magic dns under 127.0.0.11

Here is a sample site conf of nginx which proxies every request to  a container "nginx" via proxy_pass


on your loadbalancing container edit /etc/nginx/sites-available/<your site>

server
{
  listen 80;
  resolver 127.0.0.11;
  set $upstream http://nginx;
  location /
  {
    proxy_pass $upstream;
  }
}

the variable $upstream causes, that the proxy "pings" the nameserver to respond the first answering webfrontend and routes the request to that server

Here is the complete docker-compose.yml
