Creating Worker Nodes

Creating Worker Nodes

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

We'll cover the following...

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

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.

  • Lines 2–4: We define the name of the node pool and the location. The value of the cluster is interesting, though. Instead of hard-coding it or setting it ...
