GKE nodepool module

This module allows simplified creation and management of individual GKE nodepools, setting sensible defaults (eg a service account is created for nodes if none is set) and allowing for less verbose usage in most use cases.

Example usage

module "cluster-1-nodepool-1" {
  source                      = "../modules/gke-nodepool"
  project_id                  = "myproject"
  cluster_name                = "cluster-1"
  location                    = "europe-west1-b"
  name                        = "nodepool-1"
}
