google_container_node_pool

Manages a Node Pool resource within GKE. For more information see the official documentation and API.

Example usage

Standard usage

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

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

  additional_zones = [
    "us-central1-b",
    "us-central1-c",
  ]

  master_auth {
    username = "mr.yoda"
    password = "adoy.rm"
  }

  node_config {
    oauth_scopes = [
      "https://www.googleapis.com/auth/compute",
      "https://www.googleapis.com/auth/devstorage.read_only",
      "https://www.googleapis.com/auth/logging.write",
      "https://www.googleapis.com/auth/monitoring",
    ]

    guest_accelerator {
      type  = "nvidia-tesla-k80"
      count = 1
    }
  }
}

Usage with an empty default pool.

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

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

    oauth_scopes = [
      "compute-rw",
      "storage-ro",
      "logging-write",
      "monitoring",
    ]
  }
}

resource "google_container_cluster" "primary" {
  name = "marcellus-wallace"
  zone = "us-central1-a"

  lifecycle {
    ignore_changes = ["node_pool"]
  }

  node_pool {
    name = "default-pool"
  }
}

Usage with a regional cluster

resource "google_container_cluster" "regional" {
  name   = "marcellus-wallace"
  region = "us-central1"
}

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

Argument Reference

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

• region - (Optional) The region in which the cluster resides (for regional clusters).

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

Note: You must be provide region for regional clusters and zone for zonal clusters

• 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.

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

• name_prefix - (Deprecated, Optional) Creates a unique name for the node pool beginning with the specified prefix. Conflicts with 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.

The autoscaling block supports:

• min_node_count - (Required) Minimum number of nodes in the NodePool. Must be >=1 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.

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
