Kustomize: Template-Free Configuration Customization for Kubernetes
summary
Kustomize is a CLI that produces Kubernetes YAML by template-free patching of existing manifests: it reads plain YAML (no API calls), applies customization.yaml rules (bases and overlays), and emits modified YAML for kubectl apply or CI. Example workflow handles dev/staging/prod variants, name prefixes, var extraction between resources, and generated configMaps that get content-hash suffixes so deployments roll out on change. It composes with git and Helm (use helm template first), aims for rebaseable overlays and integrates into kubectl in 1.13.
