Google: google_compute_region_backend_service | docs-google-compute-region-backend-service | Creates a Region Backend Service resource for Google Compute Engine. |
google_compute_region_backend_service
A Region Backend Service defines a regionally-scoped group of virtual machines that will serve traffic for load balancing. For more information see the official documentation and API.
Example Usage
resource "google_compute_region_backend_service" "foobar" {
name = "blablah"
description = "Hello World 1234"
protocol = "TCP"
timeout_sec = 10
session_affinity = "CLIENT_IP"
backend {
group = "${google_compute_region_instance_group_manager.foo.instance_group}"
}
health_checks = ["${google_compute_health_check.default.self_link}"]
}
resource "google_compute_region_instance_group_manager" "foo" {
name = "terraform-test"
instance_template = "${google_compute_instance_template.foobar.self_link}"
base_instance_name = "foobar"
region = "us-central1"
target_size = 1
}
resource "google_compute_instance_template" "foobar" {
name = "terraform-test"
machine_type = "n1-standard-1"
network_interface {
network = "default"
}
disk {
source_image = "debian-cloud/debian-8"
auto_delete = true
boot = true
}
}
resource "google_compute_health_check" "default" {
name = "test"
check_interval_sec = 1
timeout_sec = 1
tcp_health_check {
port = "80"
}
}
Argument Reference
The following arguments are supported:
-
name
- (Required) The name of the backend service. -
health_checks
- (Required) Specifies a list of health checks for checking the health of the backend service. Currently at most one health check can be specified, and a health check is required.
-
backend
- (Optional) The list of backends that serve this BackendService. Structure is documented below. -
description
- (Optional) The textual description for the backend service. -
project
- (Optional) The project in which the resource belongs. If it is not provided, the provider project is used. -
protocol
- (Optional) The protocol for incoming requests. Defaults toHTTP
. -
session_affinity
- (Optional) How to distribute load. Options areNONE
(no affinity),CLIENT_IP
,CLIENT_IP_PROTO
, orCLIENT_IP_PORT_PROTO
. Defaults toNONE
. -
region
- (Optional) The Region in which the created address should reside. If it is not provided, the provider region is used. -
timeout_sec
- (Optional) The number of secs to wait for a backend to respond to a request before considering the request failed. Defaults to30
. -
connection_draining_timeout_sec
- (Optional) Time for which instance will be drained (not accept new connections, but still work to finish started ones). Defaults to0
.
The backend
block supports:
-
group
- (Required) The name or URI of a Compute Engine instance group (google_compute_region_instance_group_manager.xyz.instance_group
) that can receive traffic. Instance groups must contain at least one instance. -
balancing_mode
- (Optional) Defines the strategy for balancing load. Defaults toUTILIZATION
-
capacity_scaler
- (Optional) A float in the range [0, 1.0] that scales the maximum parameters for the group (e.g., max rate). A value of 0.0 will cause no requests to be sent to the group (i.e., it adds the group in a drained state). The default is 1.0. -
description
- (Optional) Textual description for the backend. -
max_rate
- (Optional) Maximum requests per second (RPS) that the group can handle. -
max_rate_per_instance
- (Optional) The maximum per-instance requests per second (RPS). -
max_utilization
- (Optional) The target CPU utilization for the group as a float in the range [0.0, 1.0]. This flag can only be provided when the balancing mode isUTILIZATION
. Defaults to0.8
.
Attributes Reference
In addition to the arguments listed above, the following computed attributes are exported:
-
fingerprint
- The fingerprint of the backend service. -
self_link
- The URI of the created resource.
