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.

Is kustomize for k8s backward chaining?

The README for kustomize says that It's like make, in that what it does is declared in a file, and it's like sed, in that it emits edited text. Does this analogy extend beyond the fact that files are used to declare what is needed? Or, is…
