Map a Kubernetes cluster with one command

DNS is the way things discover other things on the internet, but did you know there's a cool little network mapping tool that will build a realtime map of your Kubernetes cluster using DNS?

It's called the network mapper from Otterize and in the video below I run it through its paces - then unleash it on the OpenTelemetry demo to see how it copes (spoiler: well!)

Here's the code for the little visualisation app I created too: https://github.com/agardnerIT/network-mapper-visualizer
