Terraform | How to "kubectl kustomize --enable-helm"?

[NeuhausMatheus]

I would like to use only custom resources for the work that I'm doing. I currently want to test how we can deploy helm Chart + kustomize in Terraform to stop forking upstream helm charts.

Inside the "data_source_kustomization_overlay.go" from the repository "terraform-provider-kustomization" I saw that we have:

https://github.com/kbst/terraform-provider-kustomization/blob/master/kustomize/data_source_kustomization_overlay.go#L658

How can I use this "enable-helm" feature within this code example below:

main.tf:
`

data "kustomization_build" "test" {
  path = "terraform-provider-kustomization-master/kustomize/test_kustomizations/basic/initial"
}

resource "kustomization_resource" "from_build" {
  for_each = data.kustomization_build.test.ids

  manifest = data.kustomization_build.test.manifests[each.value]
}

data "kustomization_overlay" "test" {
  namespace = "test-overlay"

  resources = [
    "terraform-provider-kustomization-master/kustomize/test_kustomizations/basic/initial"
  ]

  patches {
    patch = <<-EOF
      - op: add
        path: /spec/template/spec/containers/0/env
        value: [{"name": "TEST", "value": "false"}]
    EOF

    target {
      group   = "apps"
      version = "v1"
      kind    = "Deployment"
      name    = "test"
    }
  }
}

resource "kustomization_resource" "from_overlay" {
  for_each = data.kustomization_overlay.test.ids

  manifest = data.kustomization_overlay.test.manifests[each.value]
}

`

What I'm looking for is to use this Kustomization.yaml file:

`

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

namespace: matheus-neuhaus

resources:
- namespace.yaml
- ../../_example_app

helmGlobals:
  chartHome: ../../../charts/dev
helmCharts:
- name: cert-manager
  releaseName: cert-manager
  namespace: cert-manager
  valuesFile: values.yaml
  includeCRDs: true

`
If I run that main.tf with that kustomize.yaml I get an error asking to "enable" the --enable-helm flag:

I didn't find any discussion tabs at "https://github.com/kbst/terraform-provider-kustomization" to start this discussion.

You have to add a kustomize_options block to the kustomization_overlay data source and set the attribute you linked inside the block.
