For me, it was PhotoPrism. I used to be an idiot, and used Google Photos as my gallery. I knew that it was terrible for privacy but was too lazy to do anything about it. When Google limited storage for free accounts, I started looking for alternatives. Tried out a lot of stuff, but ended up settling on PhotoPrism.
It does most things that I need, except for multiple user support (it’s there in the sponsored version now). It made me learn a bit about Docker. Eventually, I learned how to access it from outside of my home network over Cloudflare tunnel. I’m happy that I can send pics/albums to folks without sharing it to any third party. It’s as easy as sending a link.
Now I have around a dozen containers on a local mini pc, and a couple on a VPS. I still route most things through Cloudflare tunnels (lower latency), only the high bandwidth stuff like Jellyfin are routed through a wireguard tunnel through the VPS.
Anyway, how did you get into selfhosting? (The question is mostly meant for non-professionals. But if you’re a professional with something interesting to share, you’re welcome as well.)
Ever since the CS1.6 days I wanted to have a server, but it was only when I got a free Raspberry Pi that I actually started self hosting stuff 24/7. I put OwnCloud on it and a bunch of scripts to track and statistically evaluate my investments, and just took off from there. Like many others, my desire to disconnect and reduce my dependency on “Big Tech” was a big motivator, but so too was “fun” and having things exactly the way I liked.
In the beginning I rolled my own scripts most of the time, but now I tend to use more off the shelf tools as self hosting has gone more and more “mainstream”/accessible and docker has become ubiquitous.
I still do my own scripts tbf, like my DIY smart thermostat/heat pump controller. Ultimately it’s just a lot of fun.
