Rancher terraform does not work with Hetzner

[namqdam]

Hi, I have error when using with Hetzner cloud when install cert-manager.

module.rancher_common.helm_release.cert_manager: Creating...
│
│ Error: could not download chart: failed to download "https://charts.jetstack.io/charts/cert-manager-v1.8.0.tgz"
│
│ with module.rancher_common.helm_release.cert_manager,
│ on ../rancher-common/helm.tf line 4, in resource "helm_release" "cert_manager":
│ 4: resource "helm_release" "cert_manager" {
│
│

my config:

cert_manager_version = "1.8.0"
docker_version = "20.10"
rancher_kubernetes_version = "v1.21.11+k3s1"
rancher_version = "2.6.4"
workload_kubernetes_version = "v1.21.10-rancher1-1"

Please help me. Thank you.

I can't reproduce this issue. Provisioning works fine with the default cert-manager version in the module (1.7.1) as well as with 1.8.0.

The URL is also correct and points to the packaged Helm chart. Do you have internet connectivity on the machine where you are running Terraform? Is there maybe some Proxy, Firewall or Anti-Virus Scanner that could block the download?

If you run TF_LOG=debug terraform apply, you should get more detailed logs that may include more details on why the download failed.

helm repo update fixed it for me, although i don't have jetstack repo installed

@obi12341 Thanks for posting this, had the same issue on AWS. Had to install helm on my local machine and then do a repo update like you did. Once that was done, the apply worked!
