kustomize-helmgenerator

A simple exec plugin for Kustomize written in go to declaratively define helm template outputs as a Kustomize generator.

HelmGenerator is purposely not written as a Kustomize go plugin to prevent integration difficulties with various versions of Kustomize.

Examples

The HelmGenerator API is heavily inspired by the Helm portion of the argocd-cm api here. An example of a feature rich generator is below:

apiVersion: wolfs.io/v1beta1
kind: HelmGenerator
metadata:
  name: helmGenerator

# Charge release name
releaseName: dog

# Path to a chart directory or .tgz of a chart (only local chart paths supported right now)
chartPath: testdata/mocha/

# Namespace to deploy chart to
namespace: coco

# Ordered helm value imports (values will be overrided in order)
valueFiles:
  - testdata/values-base.yaml
  - testdata/values-prod.yaml

# Generic map of values (will overwrite valuesFiles above)
values: |
