Mid 2022, a friend of mine helped me set up a selfhosted Vaultwarden instance. Since then, my "infrastructure" has not stopped growing, and I've been learning each and every day about how services work, how they communicate and how I can move data from one place to another. It's truly incredible, and my favorite hobby by a long shot.
Here's a map of what I've built so far. Right now, I'm mostly done, but surely time will bring more ideas. I've also left out a bunch of "technically revelant" connections like DNS resolution through the AdGuard instance, firewalls and CrowdSec on the main VPS.
Looking at the setups that others have posted, I don't think this is super incredible - but if you have input or questions about the setup, I'll do my best to explain it all. None of my peers really understand what it takes to construct something like this, so I am in need of people who understand my excitement and proudness :)

I see everyone else have already chimed in on whats so great about Caddy (because it is!), one thing that has been a thorn in my side though is the lack of integration of fail2ban since Caddy has moved on from the old common log format and moved on to more modern log formats. So if you want to use a IPS/IDS, you'll have to either find a creative hack to make it work with fail2ban or rely on more modern (and resource heavier) solutions such as crowdsec.
You can install the log transformer plugin for Caddy and have it produce a readable log format for fail2ban: https://github.com/caddyserver/transform-encoder
I had this setup on my VPS before I moved to a k3s setup. I will take a look at how to migrate my fail2ban setup to the new server.
Cool, thanks for this! As a user of Caddy through Docker, I suppose I need to find a way to build a docker image to be able to do this?
Sometimes new simple technologies makes things simple - but only as long as one intends to follow how they are used... 🙃
I think so, but if you check the official image you can definitely find out how to include custom plugins in it. I think the documentation might mention a thing or two about it too.
