Potential Terraform Configuration

  name     = var.cluster-name
  serviceIpv4Cidr = "10.0.0.0/16" // something like this is what I would imagine
}

hi @jwenz723, thank you for creating this issue! To follow along the AWS API, just noting here that this new argument service_ipv4_cidr should also appear w/in it's parent argument kubernetes_network_config, with an updated potential config:

resource "aws_eks_cluster" "cluster" {
  name     = var.cluster-name
  kubernetes_network_config {
    service_ipv4_cidr = "10.0.0.0/16" // something like this is what I would imagine
}
