Description
I started out with your traefik v2 https ssl localhost. This uses makecert to make your own local certs. The issue with this setup, is an invalid cert which will constantly be warned by browser is not valid. You can still accept though.
The alternative to this is what Techno Tim did using Traefik + cloudflare local dns + lets encrypt. So what his method does is allow to setup a reverse proxy (same one like yours), but have a working valids lets encrypt cert for https which can be used locally for a local homelab setup without exposing to the internet.

The alternative to that is Wolfgang's approach but using Nginx proxy manager

So you can either go with Nginx Proxy Manager or traefik. But both managed to gets working https valid certs for local homelab setup using lets encrypt.
Wolfgang uses either a paid domain or free one e.g. duckdns. Whereas technotim uses similar to your approach Heziode, a local domain e.g. dashy.local.lan Either would work fine for local homelab setup.
Anyway appreciate Heziode's project since i started out with it, but i came across 2 good options that resolved the valid https cert issue, so thought i'd mention here for others wanting to setup for local homelab but wondering how to improve upon this existing project.
