A lot of Kubernetes observability projects require very invasive deployments. My team was looking for something more lightweight and non-invasive, so we built the network mapper, an open source project which uses DNS traffic to map service traffic within Kubernetes clusters.

We’ve just added a CLI that creates a graphical map of your cluster using graphviz: otterize network-mapper visualize.

I’m curious to learn: Is such a map valuable to you? How would you use the information? Do you already have a map of your cluster, and was it difficult to acquire?
