module "oke" {
  providers = {
    oci.home = oci
  }
  source  = "oracle-terraform-modules/oke/oci"
  version = "5.4.3"

Debug Output

module.oke.module.oke.module.extensions[0].null_resource.cluster_autoscaler[0] (remote-exec): error: error validating "/home/opc/yaml/cluster_autoscaler.yaml": error validating data: failed to download openapi: the server has asked for the client to provide credentials; if you choose to ignore these errors, turn validation off with --validate=false

Panic Output

Expected Behavior

The autoscaler is successfully installed.

Actual Behavior

module.oke.module.oke.module.extensions[0].null_resource.cluster_autoscaler[0] (remote-exec): error: error validating "/home/opc/yaml/cluster_autoscaler.yaml": error validating data: failed to download openapi: the server has asked for the client to provide credentials; if you choose to ignore these errors, turn validation off with --validate=false

Steps to Reproduce

1. Create a simple cluster with module version and kubernetes version specified above with cluster_autoscaler_install = true

This turned out to be non-obvious, following the quickstart guide.

Suggest adding the following to the example manifest in order to be able to access cluster from operator node.

  create_iam_resources = true
  create_iam_autoscaler_policy = "always"
  create_iam_operator_policy = "always"
  create_iam_worker_policy = "always"
