Hello people, I recently rented a vps server from OVH and I want to start hosting my own piefed instance and a couple other services. I am running debian 13 with docker, and I have nginx proxy manager almost set up. I want to set up subdomains so when I do social.my.domain it will go to my piefed instance, but how do I tell the machine to send piefed traffic to this subdomain and joplin traffic (for example) to another domain? Can I use nginx/docker natively for that or do I have to install another program. Thanks for the advice.


I’ve seen many default docker-compose configurations provided by server software that expose the ports of stuff like databases by default (which exposes it on all host interfaces). Even outside docker, a lot of software, has a default configuration of “listen on all interfaces”.
I’m also not saying “evil haxxors will take you over”. It’s not the end of the world to have a service requiring authentication exposed to the internet, but it’s much better to only expose what should be public.
Yep, fair. Those docker-composes which just forward the ports to the host on all interfaces should burn. At least they should make them 127.0.0.1 forwards, I agree.
