terraform-provider-helm: error: failed to download (hint:running helm repo update may help)

⚠️ Note from maintainers about this issue, please read

This issue is attracting a lot of thumbs because it is not one specific issue. This error message comes from the helm package and is a catch-all error that is displayed when the chart fails to download for any reason. The real error is suppressed and debugging has to be enabled to surface it.

Please add HELM_DEBUG=1 to your terraform apply and run again to see if the error message is more specific. If the error message shows something different please open a new issue with the output.

Original Issue

Terraform Version and Provider Version

Terraform v0.12.26

Provider Version

provider.google v3.27.0
provider.google-beta v3.27.0
provider.helm v1.2.3
provider.random v2.2.1

Affected Resource(s)

helm_release

Terraform Configuration Files

Provider in root module

provider "helm" {
  kubernetes {
    config_context = "name-of-my-context"
  }
}

Basics of the module

resource "helm_release" "gitlab-runner" {
  name                    = "gitlab-runner"
  repository            = "https://charts.gitlab.io"
  chart                    = "gitlab-runner"
  version                 = "0.18.0"
  namespace          = "gitlab-runner"
  create_namespace   = true
...
}

Execution of the root module

module "gitlab_runner" {
  source = "../modules/helm_gitlab_runner"
  tags = "test, test2"
  registration_token = "removed"
}

Expected Behavior

Chart should be successfully downloaded and the plan applied

Actual Behavior

helm_release.gitlab-runner: Creating...

Error: failed to download "https://gitlab-charts.s3.amazonaws.com/gitlab-runner-0.18.0.tgz" (hint: running `helm repo update` may help)

  on main.tf line 1, in resource "helm_release" "gitlab-runner":
   1: resource "helm_release" "gitlab-runner" {

Steps to Reproduce

terraform init
terraform plan
terraform apply -auto-approve

Important Factoids

The target cluster is a GKE instance and the active kubectl ctx is correct and functions fine.

I have tried all kinds of variations here such as setting `chart = “https://gitlab-charts.s3.amazonaws.com/gitlab-runner-0.18.0.tgz” , removing version, older versions etc etc

I have done all kinds of resets of helm cache, remove and add repos, update etc etc

Have also used the terraform docker image to ensure that its not an environmental problem of some sort

Hi folks, I’m pinning this issue for visibility. This issue is attracting a lot of thumbs because it is not one specific issue. This error message comes from the helm package and is a catch-all error that is displayed when the chart fails to download for any reason. The real error is suppressed and debugging has to be enabled to surface it.

Please add HELM_DEBUG=1 to your terraform apply and run again to see if the error message is more specific. If the error message shows something different please open a new issue with the output.

I’m going to close this issue now to avoid further confusion.

It worked when I used terraform 0.13 but when switching back to terraform 0.12.28 it is failing

resource “helm_release” “cluster_autoscaler” { name = “autoscaler” repository = “https://kubernetes.github.io/autoscaler” chart = “cluster-autoscaler-chart” namespace = “cluster-autoscaler”

set { name = “autoDiscovery.clusterName” value = var.cluster_name }

set { name = “rbac.create” value = true }

set { name = “rbac.serviceAccountAnnotations.eks.amazonaws.com/role-arn” value = aws_iam_role.argocd_nodegroup_role.arn }

depends_on = [aws_eks_cluster.argocd_cluster, aws_eks_node_group.argocd_nodegroup, kubernetes_namespace.cluster_autoscaler]

}

@llnformer As above, if you change:

chart = "eks/aws-node-termination-handler" to chart = "aws-node-termination-handler"

The release should work.

I had a similar issue when I add verify = true included in my helm_release. When I set verify to false the error went away. I’d consider this a workaround as I don’t know why verification of the package fails.

I was having this exact problem with an agones install, and was able to reproduce it while attempting a direct install too, same failure text. So I added a debug to the manual install:

helm --debug install agones https://agones.dev/chart/stable/agones-1.7.0.tgz -n agones-system

That told me that the issue was that there was a missing file:

Error: no cached repo found. (try 'helm repo update'): open ~/.cache/helm/repository/local-index.yaml: no such file or directory

I took a guess that this was actually the file in ~/.helm/repository/local/index.yaml that probably got missed in a helm 2to3 migration. So, I copied it over:

cp ~/.helm/repository/local/index.yaml ~/.cache/helm/repository/local-index.yamll

Now when I run my terraform apply, no errors (at least because of this)
