Terraform: helm chart not found in repo but work in cli

I've got this problem when using terraform helm_release provider:

Error: chart "external-dns/external-dns" not found in https://kubernetes-sigs.github.io/external-dns repository

While it works with helm:

external-dns    https://kubernetes-sigs.github.io/external-dns

The terraform script:

resource "helm_release" "external-dns" {
  name       = "external-dns"
  repository = "https://kubernetes-sigs.github.io/external-dns"
  chart      = "external-dns/external-dns"
  namespace  = "default"

  values = [
    file("charts/external-dns.yaml")
  ]
  depends_on = [kubernetes_secret.cloudflare-api]

external-dns.yaml:

---
provider: "cloudflare"
domainFilter: "setupad.net"
extraArgs:
    - --cloudflare-proxied
env:
    - name: "CF_API_KEY"
      valueFrom:
        secretKeyRef:
            name: cloudflare-api
            key: token
Solution

  • Change it to external-dns rather than external-dns/external-dns.

    resource "helm_release" "external-dns" {
  name       = "external-dns"
  repository = "https://kubernetes-sigs.github.io/external-dns"
  chart      = "external-dns"
  namespace  = "default"

  values = [
    file("charts/external-dns.yaml")
  ]
  depends_on = [kubernetes_secret.cloudflare-api]
}
