Creating Worker Nodes

Learn how to create worker nodes and view them using Terraform.

Defining worker nodes

We can manage worker nodes through the google_container_node_pool module. We’ve prepared yet another definition that we can use.

Explaining the output

Press + to interact
resource "google_container_node_pool" "primary_nodes" {
  name         = var.cluster_name
  location     = var.region
  cluster      = google_container_cluster.primary.name
  version      = var.k8s_version
  node_config {
    preemptible  = var.preemptible
    machine_type = var.machine_type
    oauth_scopes = [
      "https://www.googleapis.com/auth/cloud-platform"
    ]
  }
  autoscaling {
    min_node_count = var.min_node_count
    max_node_count = var.max_node_count
  }
  management {
    auto_upgrade = false
  }
  timeouts {
    create = "15m"
    update = "1h"
  }
}

That definition is a bit bigger than the ones we’ve used before. There are more things we might want to define for worker nodes, so that definition has a few more fields than others.
