helmfile applies defaultInherit templates to releases

Introduced 2026-05-22 · score 0.98

HOW TO USE IT

When releases share templates, set top-level `defaultInherit` in `helmfile.yaml` to a template name or ordered list; Helmfile applies them to every release and does not duplicate templates already explicitly inherited. Use release `inherit[].except` to omit fields.

templates: defaults: namespace: kube-system defaultInherit: defaults releases: - name: <release-name> chart: <chart> version: <version>
defaultInherit: - ns-template - defaults
releases: - name: <release-name> chart: <chart> inherit: - template: defaults except: - values

WHY THIS HELPS

Configure a Helmfile repository whose releases share one or more templates without repeating `inherit` on every release.

BEFORE THIS CHANGE

Specify `inherit` on each release that should inherit the template.

REQUIREMENTS AND LIMITATIONS

  • Version: v1.5.2
  • defaultInherit: Top-level default template name or list of template names applied to all releases; list order determines merge order.
  • inherit[].template (required): Name of the release template to inherit.
  • inherit[].except: List of fields to exclude from that template.
  • Prerequisite: Use Helmfile v1.5.2 or later for this feature.
  • A referenced template must exist; the source mentions an error for a non-existent template.
