How to use multple services together

If you want to proxy your Tomcat server with Nginx, modify or create your own nginx.conf that redirect all requests to upstream server tomcat,

# ...
server {
    server_name localhost;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://tomcat:8080$request_uri;
    }
}

and start Nginx and Tomcat together,

$ docker-compose up tomcat nginx -d

and you're done!

Enjoy yourself!!
