Create diagrams from the Kubernetes API with go-diagrams.

Kubernetes diagrams

k8s-diagrams creates diagrams from your kubernetes clusters.

You just have to provide a namespace (or not), and you get a picture from the current state of your cluster. For now it only suppports namespaces, deployments, replicaSets, daemonSets, statefulSets, pods, services and ingresses. I may add other k8s API objects in the future...

How do I build it?

$ make build

Usage

$ ./k8s-diagrams --help                                                                                           ✔
