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.
I have NixOS running on mine and I write everything in comments in my
configuration.nix. Usually I’ll write notes about why I set a certain option above the line where I do it but I also have a section at the start that describes anything to be aware of if I’m moving this configuration to another machine. For example “This assumes a drive is mounted on/mnt/backup0”
