A public-health platform team debates one-off kubectl apply of raw YAML versus packaging cluster addons. Why do teams commonly prefer Helm or Kustomize for repeatable addon installs?
Select an answer to reveal the explanation.
Short Explanation
One-off kubectl apply is like taping handwritten sticky notes on each clinic server—easy once, painful the tenth time. Helm charts and Kustomize overlays give you a repeatable, versioned recipe for the same addon. They do not replace the API server or turn off RBAC.
Full Explanation
Cluster components such as ingress controllers or cert managers are typically installed many times across environments. Helm and Kustomize provide parameterized, reviewable packages with clearer upgrade and rollback stories than ad-hoc copied YAML. Packaging does not remove core Kubernetes control-plane requirements or bypass authorization.
