Every other large-ish product I've maintained would have a chart at least this large. Complex systems are complicated to maintain, regardless of platform.
You've worked on complex systems with charts? Most places I've worked lack charts and documentation. The flow chart only exists in pieces of the people's heads still working there, the rest in employees who left.
That's one of the strengths with K8s, at least there is documentation, unlike a 1000 line perl script with no tests which does service discovery.
I said "would have a chart" not "had a chart". :-D Of course it wasn't properly documented. :-(
I fully agree on that being a major strength of k8s. Looking at the resource manifests gives a ton of insight into how a system is supposed to function.
