This is a very simple demonstration of the nginx sub_filter module and how to use it to replace content served up by nginx.
To run this demo you will need
- docker
- docker-compose
- a clear mind
To run this demo simply run docker-compose up from the project base.
There are then two URLs:
http://<dockerhost>:5000- direct node.js applicationhttp://<dockerhost>:80- nginx proxy
You can use curl or httpie to test this all out.
$ http http://$(docker-machine ip):5000
HTTP/1.1 200 OK
Connection: keep-alive
Content-Type: text/html
