I Didn't Need a DAG. I Needed Cron.

Hey, nerds! Stop me if you’ve heard this one before. Every homelab eventually hits the same wall. You have a pile of guests, a pile of small chores those guests need done on a schedule and absolutely no desire to SSH into each one by hand. Disk usage, uptime checks, arbitrary commands, pending updates, failed systemd units, the list goes on. This is all boring stuff that quietly rots away if nobody looks at it. So I went shopping for an automation platform. I came back with nothing and then built one out of SSH, bash, cron and other bits and bobs already running in the homelab. It’s called NetRunner, because I’m physically incapable of naming anything in this network without a cyberpunk reference.
