Securing Raspberry Pi with Reverse Proxy and or Cloudflare Proxy Tunnel

Option #1: Reverse Proxy with NGINX-PROXY
Ok so I’ve done a lot of research on reverse proxys and they are great at protecting your internal assets but there are some inherent security flaws that you have to live with if you want perfect security. Lets face it there is no such thing, but we can get pretty close.

Some of the flaws of a reverse proxy are that you still need to open ports up on your firewall to get them to work, in most cases. Sure you can run a VPN to secure the ports but even then in many cases the VPN needs to have their own ports exposed on your firewall. We will cover a method below that eliminates this risk.
So then how do you implement a reverse proxy on Docker? Luckily there are many Docker images that offer dynamic proxys that automatically bind to new containers and sit between you and their services so long as you configure each container properly. One such proxy is called NGINX-PROXY and its really awesome let me show you how it works.
