The templates Directory and NOTES.txt

Where manifests live and how notes are rendered.

Where Manifests Live

The templates directory is the heart of a chart. Every file here becomes a Kubernetes manifest after Helm renders it. 🧩

templates/
  deployment.yaml
  service.yaml

Files in templates are not plain YAML: they are Go templates. Helm fills in the double-brace actions before sending them to the cluster.

spec:
  replicas: {{ .Values.replicaCount }}
