Wrapping my head around reverse proxy was a game changer for me. I could finally host things that are usefull outside my LAN. I use Nginx-Proxy-Manager which makes the config simple for lazy's like me.
NPM is awesome until you have a weird error that the web GUI does not give a hint about the problem. Used it for years at this point and wouldn't consider anything else at this point. It just works and is super simple.
Those ones are fun. If you delete an SSL certificate and haven't removed it from a proxy, the entire container goes down and you have to trawl through logs to find what went wrong.
Used to mess around with multiple Apache Proxy Servers. When I left that job I found Docker and (amongst other things) NPM and I swear, I stared at the screen in disbelief on how easy the setup and config was. All that time we wasted on Apache, the issues, the upgrades, the nightmare in setting it all up...
If I were to do that job again I would not hesitate to use NPM 100% and stop wasting my time with that Apache Proxy mess.
Do you serve things to a public? Like a website? Because unless you're serving a public, that's dumb to do... and you really don't understand the purpose of it.
If all you wanted was the ability to access services remotely, then you should have just created a WireGuard tunnel and set your phone/laptop/whatever to auto connect through it as soon as you drop your home Wifi.
A lemmy instance, a wiki, and a couple of other website type things, yes.
Publicly facing things are pretty limited, but it's still super handy inside the LAN with Adguard Home doing DNS rewrites to point it to the reverse proxy.
I appreciate what you're saying, though. A lot of people get in trouble by having things like Radarr etc. open to the internet through their reverse proxy.
Am I making a mistake by having my Jellyfin server proxied through nginx? The other service I set up did need to be public so I just copied the same thing when I set up Jellyfin but is that a liability even with a password to access?
This is very short sighted. I can think of dozens of things to put on the open internet that aren’t inherently public. The majority are things for sharing with multiple people you want to have logins for. As long as the exposed endpoints are secure, there’s no inherent problem.
Plex, Jellyfin, VaultWarden, AdGuard, Home Assistant, GameVault, any flavor of pastebin, any flavor of wiki, and the list goes on.
If you’re feeling spicy throw whatever the hell you want onto a reverse proxy and put it behind a zero trust login.
The idea that opening up anything at all through to the open internet is “dumb” is antiquated. Are there likely concerns that need to be addressed? Absolutely. But don’t make blanket statements about virtually nothing belonging on the open internet.
