Own your YAML: extending Kustomize via Plugins
summary
Kustomize runs replacement transformer, templater, and sops plugin extensions to modify or generate Kubernetes YAML during render. Replacement copies specific YAML trees or list items from one resource into others to deduplicate shared values (example: copying player.initialLives into multiple configmaps); templater uses Go templates with Sprig and twoyaml to produce N near-identical resources (Airship uses it to generate bare-metal host CRs from three inputs); sops decrypts annotated fields just-in-time and delivers cleartext to the API server without writing secrets to disk. Kustomize supports local plugins and is moving to containerized KRM functions.
