Hello, how do you document your home lab? Whether it's a small server or a big one with firewall and more nodes. I have a small pc with Proxmox and there I have a VM with OpnSense. After I've entered my VPN as a interface in OpenSense, I noticed that I slowly lose the overview with the different rules that I have built in my firewall. And I know that my setup is relatively easy in comparison to others here in this community. I want to have a quick Overview at the various VMs, like the Lxc container, Docker containers that I have in this and the IP addresses that I have assigned to them. I search for a simple an intuitiv way for beginners.

Secrets go in Keepass.

For server configs, a LibreOffice Writer file per machine (except for RPs, I only have one for those), written as a didactic manual explaining how to install and configure everything (I work on bare metal still). I started that way since diving into self-hosting was also a way to learn Linux, Sys-Admin and web-hosting. I don't do anything without updating the relevant chapters, or creating new ones. Not gonna lie: it's tedious. But also a life-saver, and the rationals for my choices remain available years later, which is priceless in many ways.

Once upon a time I had neat network gear running, and I mostly YOLO-ed the doc for those, relying instead on the firmware/config backups. I had to put those devices away, but when I finally get to play with them again, I'm going to suffer re-learning and re-discovering everything.

Recently, I got to hack and old console, and just did a chronological log-file with actions taken and URLs to guides, instead of writing down everything myself. It got me thinking I might add a simple log-file to track my actions, on top of my usual guides.

Or not. Having a life is nice too ๐Ÿ˜
