Out of date authentication API version for Kubernetes?

[yorinasub17]

I am getting the following error message when using the Gruntwork modules:

Kubernetes cluster unreachable: exec plugin: invalid apiVersion "client.authentication.k8s.io/v1alpha1"

How do I address this?

Tracked in ticket #108805

This is due to the Kubernetes library dependencies of the helm provider being upgraded beyond 1.24.x, where the v1alpha1 API was removed.

We are currently working on a fix for kubergrunt to be compatible with generating a v1beta1 auth token. In the meantime, it is recommended to work around this by pinning the helm provider version to 2.5.1, the last known version to work with v1alpha1. You can pin the provider version by following the same strategy recommended in #187.

Refer to hashicorp/terraform-provider-helm#893 for more info.

@yorinasub17 Thanks for the info!

If anyone is looking for a quick fix, this worked for us in the top-level terragrunt.hcl file:

generate "helm_provider_version" {
  path      = "helm_version_override.tf"
  if_exists = "overwrite_terragrunt"
  contents  = <<EOF
terraform {
  required_providers {
    helm = {
      source  = "hashicorp/helm"
      version = "= 2.5.1"
    }
  }
}
EOF
}
