You want to use Nginx to proxy to a protected app / service, and you have some kind of external authentication system.
Usual solutions involve:
- Locking down via IP address
- Adding Basic Auth
However, if you already have an existing authentication system, this repo gives an example of how you can use nginx to hook into it.
docker-compose up
If you hit http://localhost:8000, you will see by default you will receive a 403 Forbidden
I've made a basic auth backend which looks for the presence of an X-Juddling header, and then it will allow you to proxy through to the protected content.
http http://localhost:8000 X-Juddling:1
You'll get a 200 back and have acess to the shared content 🎉
