Here a simple example of my infrastructure at home, simple and just enought for my need :)
The benefits of reverse proxy is
- load balancing
- caching content and web acceleration for improved performance
- secure SSL encryption
- protection from DDoS attacks and related security issues. (in comming Naxsi or ModSecurity )
In my case i will use this component only for ssl encryption, and control the access by using opensoruce tools like basic authent, Fail2ban, MFA, and ip filtered Actually i expose only 1 server on 443/80
If i use a dns server like google (8.8.8.8) i must registred all my local servers. And with my untrust and trust zonal, i need DNS view.
In my case i need DNS view, but Pi-hole don't implemented this feature.
Trivy is a simple and comprehensive vulnerability scanner for containers. Very easy to use. All need for scanning specify target such as an image name of the container.

The tag latest is used by default in my examples. In my "production" i use a specific version. I use latest in my DEV environment.
Because is "Self-hosted"
In certain scenarios, you might not want to push your images outside of your network. In my case you can set up a local registry using the open source software project Distribution.

You can use this exporter

and build a similar dashboard with this :
I use cron to schedule some scripts. Here is an example of my nginx cron job :
