There have been a few Reddit, Lemmy and Youtube posts over the past week or so about Nginx Proxy Manager and their shortfalls, mostly towards CVEs and other security issues.
The problem is that unlike Traefik, NGINX Proxy Manager is actually easy to use. And before you recommend Caddy, that also has no GUI.
What do you use, if you have stuff exposed to the outside?
Traefik just need container labels. Most of the time it’s only 4 labels for the container you want to expose. Copy to a self hosted wiki and you’re good to go.
I did that on Traefik 1 on an older stack, but since moving to Traefik 2, I'm all containers, so I haven't done it on Traefik 2 yet. However, I'd imagine maybe you can use the load balancer example with just 1 private-ip server behind it? https://doc.traefik.io/traefik/routing/services/
