Questions tagged [kustomize]

Questions about using kustomize to create and modify Kubernetes manifests in an immutable way.

Kustomize traverses a Kubernetes manifest to add, remove or update configuration options without forking. It is available both as a standalone binary and as a native feature of kubectl. Kustomize supports taking a base set of Kubernetes manifest and applying overlays that apply patches to generate an environment-specific version of the base manifest. It also included generators for configuration maps and secrets.
