Kustomize is a Kubernetes-native configuration management tool built directly into kubectl (kubectl apply -k). We trial it under Tool in the garden.

Summary

Kustomize shines for teams managing a small number of Kubernetes environments with predictable variance (namespace, replica count, image tag). The overlay model keeps base manifests clean and diffs readable. However, it lacks Helm’s packaging, dependency management, and release lifecycle , for anything that needs to be distributed or versioned as a unit, Helm is still the stronger choice. Trial it on a new service before adopting broadly.
