Hi @yugandhar-btc thanks for the report. I believe that the function anytrue requires Terraform v0.14 or later, and it appears from above you are using Terraform v0.13.0.

Could you please re-try with Terraform v0.14 or later, and if it is still failing provide an updated example?

Hi @yugandhar-btc

I suspect the underlying kubernetes provider maybe defaulting to localhost as noted in your error. I've opened #1208 to investigate.

If you are attempting to use with an existing GKE cluster, you might try adding the following with the correct values for your GKE cluster:

data "google_client_config" "default" {}

provider "kubernetes" {
  host                   = "https://${module.gke.endpoint}"
  token                  = data.google_client_config.default.access_token
  cluster_ca_certificate = base64decode(module.gke.ca_certificate)
}

Alternatively you might want to look at this example which creates a GKE cluster with ASM.

Hi @yugandhar-btc - The documentation has been updated to include the required Kubernetes provider configuration.
