These 3 Docker containers turn my homelab into the ultimate network diagnostics tool

Early on, when I had just started getting into homelabbing and self-hosting, my initial assumption was that once I configured a service properly, and got it up and running, it would just stay that way indefinitely. As I set up more and more services, my mini homelab grew to include a couple of servers and VPS instances. It started getting out of hand a bit. I started experiencing my first service outages. Apparently, a homelab requires maintenance.
