Creating Worker Nodes

Learn to create worker nodes and view them using Terraform.

We'll cover the following...

Defining worker nodes

We can manage worker node pools (beyond the default one) through the azurerm_kubernetes_cluster_node_pool module. We’ve prepared yet another definition that we can use.

resource "azurerm_kubernetes_cluster_node_pool" "secondary" {
  name                  = "${var.cluster_name}2"
  kubernetes_cluster_id = azurerm_kubernetes_cluster.primary.id
  vm_size               = var.machine_type
  enable_auto_scaling   = true
  max_count             = var.max_node_count
  min_count             = var.min_node_count
}

Explaining the output

  • Line 2: We define the name of the node pool.
  • Line 3: We define the ID of the Kubernetes cluster (kubernetes_cluster_id). Instead of hard-coding it or setting to a value, we’re telling Terraform to use the ID field of the azurerm_kubernetes_cluster.primary resource.
  • Lines 4–7: Further on, we have the size of the VMs (vm_size), whether auto-scaling should be enabled (enable_auto_scaling), and the maximum (
