After 1.5 years of learning selfhosting, this is where I'm at
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 :)

What is the proxy in front of crowdsec for?
If you're referring to the "LabProxy VPS": So that I don't have to point a public domain that I (plan to) use more and more in online spaces to my personal IP address, allowing anyone and everyone to pinpoint my location. Also, I really don't want to mess with the intricacies of DynDNS. This solution is safer and more reliable than DynDNS and open ports on my router thats not at all equipped to fend off cyberspace attacks.
If you're referring to the caddy reverse proxy on the LabProxy VPS: I'm pointing domains that I want to funnel into my homelab at the external IP of the proxy VPS. The caddy server on that VPS reads these requests and reverse-proxies them onto the caddy-port from the homelab, using the hostname of my homelab inside my tailscale network. That's how I make use of the tunnel. This also allows me to send the crowdsec ban decisions from the homelab to the Proxy VPS, which then denies all incoming requests from that source IP before they ever hit my homelab. Clean and Safe!
"pinpoint" is a bit hyperbolic. Country, state and maybe city can be pretty good, at least in the US.
It's fine if that's important to you to hide, but entirely unnecessary for most people.
Maybe. But I've read some crazy stories on the web. Some nutcases go very far to ruin an online strangers day. I want to be able to share links to my infrastructure (think photos or download links), without having to worry that the underlying IP will be abused by someone who doesn't like me for whatever reason. Maybe that's just me, but it makes me sleep more sound at night.
Thanks, but I meant the HAProxy in your homelab.
Oh, that! That app proxies the docker socket connections over a TCP channel. Which provides a more granular control over what app gets what access to specific functionalities of the docker socket. Directly mounting the socket into an app technically grants full root access to the host system in case of a breach, so this is the advised way to do it.
