Docker nginx proxy to host

Configure nginx like the following (make sure you replace IP of Docker Host) and save it as default.conf:

server {
    listen       80;
    server_name  _;
    location / {
        proxy_pass http://<IP of Docker Host>;
        index  index.html index.htm;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

Now bring up the container:

docker run -d --name nginx -p 80:80 -v /path/to/nginx/config/default.conf:/etc/nginx/conf.d/default.conf nginx
