» google_container_node_pool

Manages a node pool in a Google Kubernetes Engine (GKE) cluster separately from the cluster control plane. For more information see the official documentation and the API reference.

resource "google_container_cluster" "primary" {
  name     = "my-gke-cluster"
  location = "us-central1"

  # We can't create a cluster with no node pool defined, but we want to only use
  # separately managed node pools. So we create the smallest possible default
  # node pool and immediately delete it.
  remove_default_node_pool = true
  initial_node_count = 1

resource "google_container_node_pool" "primary_preemptible_nodes" {
  name       = "my-node-pool"
  location   = "us-central1"
  cluster    = "${google_container_cluster.primary.name}"
  node_count = 1

  node_config {
    preemptible  = true
    machine_type = "n1-standard-1"

    oauth_scopes = [

» Example Usage - 2 node pools, 1 separately managed + the default node pool

resource "google_container_node_pool" "np" {
  name       = "my-node-pool"
  location   = "us-central1-a"
  cluster    = "${google_container_cluster.primary.name}"
  node_count = 3

  timeouts {
    create = "30m"
    update = "20m"

resource "google_container_cluster" "primary" {
  name               = "marcellus-wallace"
  location           = "us-central1-a"
  initial_node_count = 3

  node_locations = [

  # Setting an empty username and password explicitly disables basic auth

» Argument Reference

  • cluster - (Required) The cluster to create the node pool for. Cluster must be present in zone provided for zonal clusters.

  • location - (Optional) The location (region or zone) in which the cluster resides.

  • zone - (Optional, Deprecated) The zone in which the cluster resides. zone has been deprecated in favor of location.

  • region - (Optional, Deprecated) The region in which the cluster resides (for regional clusters). zone has been deprecated in favor of location.

  • autoscaling - (Optional) Configuration required by cluster autoscaler to adjust the size of the node pool to the current cluster usage. Structure is documented below.

  • initial_node_count - (Optional) The initial node count for the pool. Changing this will force recreation of the resource.

  • management - (Optional) Node management configuration, wherein auto-repair and auto-upgrade is configured. Structure is documented below.

  • max_pods_per_node - (Optional, Beta) The maximum number of pods per node in this node pool. Note that this does not work on node pools which are "route-based" - that is, node pools belonging to clusters that do not have IP Aliasing enabled. See the official documentation for more information.

  • name - (Optional) The name of the node pool. If left blank, Terraform will auto-generate a unique name.

  • node_config - (Optional) The node configuration of the pool. See google_container_cluster for schema.

  • node_count - (Optional) The number of nodes per instance group. This field can be used to update the number of nodes per instance group but should not be used alongside autoscaling.

  • project - (Optional) The ID of the project in which to create the node pool. If blank, the provider-configured project will be used.

  • version - (Optional) The Kubernetes version for the nodes in this pool. Note that if this field and auto_upgrade are both specified, they will fight each other for what the node version should be, so setting both is highly discouraged. While a fuzzy version can be specified, it's recommended that you specify explicit versions as Terraform will see spurious diffs when fuzzy versions are used. See the google_container_engine_versions data source's version_prefix field to approximate fuzzy versions in a Terraform-compatible way.

The autoscaling block supports:

  • min_node_count - (Required) Minimum number of nodes in the NodePool. Must be >=0 and <= max_node_count.

  • max_node_count - (Required) Maximum number of nodes in the NodePool. Must be >= min_node_count.

The management block supports:

  • auto_repair - (Optional) Whether the nodes will be automatically repaired.

  • auto_upgrade - (Optional) Whether the nodes will be automatically upgraded.

» Timeouts

google_container_node_pool provides the following Timeouts configuration options:

  • create - (Default 30 minutes) Used for adding node pools
  • update - (Default 10 minutes) Used for updates to node pools
  • delete - (Default 10 minutes) Used for removing node pools.

» Import

Node pools can be imported using the project, zone, cluster and name. If the project is omitted, the default provider value will be used. Examples:

$ terraform import google_container_node_pool.mainpool my-gcp-project/us-east1-a/my-cluster/main-pool

$ terraform import google_container_node_pool.mainpool us-east1-a/my-cluster/main-pool
