google_compute_target_pool

Manages a Target Pool within GCE. This is a collection of instances used as target of a network load balancer (Forwarding Rule). For more information see the official documentation and API.

Example Usage

resource "google_compute_target_pool" "default" {
  name = "instance-pool"

  instances = [
    "us-central1-a/myinstance1",
    "us-central1-b/myinstance2",
  ]

  health_checks = [
    "${google_compute_http_health_check.default.name}",
  ]
}

resource "google_compute_http_health_check" "default" {
  name               = "default"
  request_path       = "/"
  check_interval_sec = 1
  timeout_sec        = 1
}

Argument Reference

The following arguments are supported:

• name - (Required) A unique name for the resource, required by GCE. Changing this forces a new resource to be created.

• backup_pool - (Optional) URL to the backup target pool. Must also set failover_ratio.

• description - (Optional) Textual description field.

• failover_ratio - (Optional) Ratio (0 to 1) of failed nodes before using the backup pool (which must also be set).

• health_checks - (Optional) List of zero or one health check name or self_link. Only legacy google_compute_http_health_check is supported.

• instances - (Optional) List of instances in the pool. They can be given as URLs, or in the form of "zone/name". Note that the instances need not exist at the time of target pool creation, so there is no need to use the Terraform interpolators to create a dependency on the instances from the target pool.

• project - (Optional) The ID of the project in which the resource belongs. If it is not provided, the provider project is used.

• region - (Optional) Where the target pool resides. Defaults to project region.

• session_affinity - (Optional) How to distribute load. Options are "NONE" (no affinity). "CLIENT_IP" (hash of the source/dest addresses / ports), and "CLIENT_IP_PROTO" also includes the protocol (default "NONE").

Attributes Reference

In addition to the arguments listed above, the following computed attributes are exported:

• self_link - The URI of the created resource.

Import

Target pools can be imported using the name, e.g.

$ terraform import google_compute_target_pool.default instance-pool
