Same thing when supplying a non-existing config_path instead (eg. generated by Terraform). Looks like this provider doesn't wait for any of the data to be available, unlike the kubernetes provider?

[Fichtme]

I've the same issue. The only way you can bypass this issue atm. is to deploy the cluster first.

Or im doing it also wrong 😂

Same issue here, I'm using the terraform-aws-modules which works well with the official kubernetes when following the recommended provider setup:

provider "kubernetes" {
  host                   = data.aws_eks_cluster.cluster.endpoint
  cluster_ca_certificate = base64decode(data.aws_eks_cluster.cluster.certificate_authority.0.data)
  token                  = data.aws_eks_cluster_auth.cluster.token
  load_config_file       = false
}

This doesn't work with kubernetes-alpha though.
