Generate Kubernetes architecture diagrams from Kubernetes manifest files, kustomization files, Helm charts, helmfile descriptors, and actual cluster state.

There are several tools to generate Kubernetes architecture diagrams, see here for a detailed list. Compared to these existing tools, the main originalities of KubeDiagrams are the support of:

• most of all Kubernetes built-in resources,
• any Kubernetes custom resources,
• customizable resource clustering,
• any Kubernetes resource relationships,
• declarative custom diagrams,
• an interactive diagram viewer,
• a modern web application,
• main input formats such as Kubernetes manifest files, customization files, Helm charts, helmfile descriptors, and actual cluster state,
• main output formats such as DOT, draw.io, GIF, JPEG, PDF, PNG, SVG, and TIFF,
• editable draw.io export,
• a very large set of examples.

KubeDiagrams is available as a Python package in PyPI, a container image in DockerHub, a kubectl plugin, a Nix flake, and a GitHub Action, see here for more details.

An Online KubeDiagrams Service is freely available at https://kubediagrams.lille.inria.fr/.

Read Real-World Use Cases and What do they say about it to discover how KubeDiagrams is really used and appreciated.

Try it on your own Kubernetes manifests, Helm charts, helmfiles, and actual cluster state!
