My home lab has a mild amount of complexity and I’d like practice some good habits about documenting it. Stuff like, what each system does, the OS, any notable software installed and, most importantly, any documentation around configuration or troubleshooting.
i.e. I have an internal SMTP relay that uses a letsencrypt SSL cert that I need to use the DNS challenge to renew. I’ve got the steps around that sitting in a Google Doc. I’ve got a couple more google docs like that.
I don’t want to get super complicated but I’d like something a bit more structured than a folder full of google docs. I’d also like to pull it in-house.
Thanks
Edit: I appreciate all the feedback I’ve gotten on this post so far. There have been a lot of tools suggested and some great discussion about methods. This will probably be my weekend now.
What is it that you all are documenting? I’m just getting started and have so far just set up docker and several containers (Plex, the *arrs, qbittorrent, gluetun) and not sure if I should be writing something down?
I document my proxmox configuration, and again for each service running on it; ports, fqdn, let’s encrypt etc. Any problems or deviations from the standard installation and how I resolved it. How I mounted my media drive and and made it accessible in Plex and Jellyfin. Any configuration that I had to search for the solution, including the actual steps and not just links that might be gone in the future. The more services you accumulate the harder it is to start the documentation, so it’s a good idea to start sooner than later.
I’d like to document what I have, and what I need to do it spin it back up with minimal effort should I need to. Esp, anything that’s unique to my setup or that I did to work around a problem. I’ve shot myself in the foot many a time where I go back to something 6 months later and I’ve long since forgotten what I did. So, if it’s not commented in a config I’m figuring it out all over again.
