# What is Kustomize?

Kustomize, Easy (Beginner), Concepts. https://k8wiz.com/uquiz/what-is-kustomize

- A. A templating engine that renders Kubernetes charts from Go templates and values
- B. A controller that keeps a cluster in sync with a Git repository
- C. A registry for publishing and sharing Kubernetes manifests
- D. A tool that customizes Kubernetes YAML through overlays, without templates

**Answer:** A tool that customizes Kubernetes YAML through overlays, without templates

**Explanation:** Kustomize reads plain Kubernetes manifests and a kustomization.yaml, then patches, labels, renames and generates objects to produce the final YAML. There is no templating language, so every input file is valid Kubernetes YAML on its own.
