+# google\_compute\_region\_autoscaler
+
+A Compute Engine Regional Autoscaler automatically adds or removes virtual machines from
+a managed instance group based on increases or decreases in load. This allows
+your applications to gracefully handle increases in traffic and reduces cost
+when the need for resources is lower. You just define the autoscaling policy and
+the autoscaler performs automatic scaling based on the measured load. For more
+information, see [the official
+documentation](https://cloud.google.com/compute/docs/autoscaler/) and
+[API](https://cloud.google.com/compute/docs/reference/latest/regionAutoscalers)
+
+
+## Example Usage
+
+```hcl
+resource "google_compute_instance_template" "foobar" {
+  name           = "foobar"
+  machine_type   = "n1-standard-1"
+  can_ip_forward = false
+
+  tags = ["foo", "bar"]
+
+  disk {
+    source_image = "debian-cloud/debian-8"
+  }
+
+  network_interface {
+    network = "default"
+  }
+
+  metadata {
+    foo = "bar"
+  }
+
+  service_account {
+    scopes = ["userinfo-email", "compute-ro", "storage-ro"]
+  }
+}
+
+resource "google_compute_target_pool" "foobar" {
+  name = "foobar"
+}
+
+resource "google_compute_region_instance_group_manager" "foobar" {
+  name   = "foobar"
+  region = "us-central1"
+
+  instance_template  = "${google_compute_instance_template.foobar.self_link}"
+  target_pools       = ["${google_compute_target_pool.foobar.self_link}"]
+  base_instance_name = "foobar"
+}
+
+resource "google_compute_region_autoscaler" "foobar" {
+  name   = "scaler"
+  region = "us-central1"
+  target = "${google_compute_region_instance_group_manager.foobar.self_link}"
+
+  autoscaling_policy = {
+    max_replicas    = 5
+    min_replicas    = 1
+    cooldown_period = 60
+
+    cpu_utilization {
+      target = 0.5
+    }
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of the autoscaler.
+
+* `target` - (Required) The full URL to the instance group manager whose size we
+  control.
+
+* `region` - (Required) The region of the target.
+
+* `autoscaling_policy` - (Required) The parameters of the autoscaling
+  algorithm. Structure is documented below.
+
+- - -
+
+* `description` - (Optional) An optional textual description of the instance
+    group manager.
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+The `autoscaling_policy` block contains:
+
+* `max_replicas` - (Required) The group will never be larger than this.
+
+* `min_replicas` - (Required) The group will never be smaller than this.
+
+* `cooldown_period` - (Optional) Period to wait between changes. This should be
+  at least double the time your instances take to start up.
+
+* `cpu_utilization` - (Optional) A policy that scales when the cluster's average
+  CPU is above or below a given threshold. Structure is documented below.
+
+* `metric` - (Optional) A policy that scales according to Google Cloud
+  Monitoring metrics  Structure is documented below.
+
+* `load_balancing_utilization` - (Optional) A policy that scales when the load
+  reaches a proportion of a limit defined in the HTTP load balancer. Structure
+is documented below.
+
+The `cpu_utilization` block contains:
+
+* `target` - The floating point threshold where CPU utilization should be. E.g.
+  for 50% one would specify 0.5.
+
+The `metric` block contains (more documentation
+[here](https://cloud.google.com/monitoring/api/metrics)):
+
+* `name` - The name of the Google Cloud Monitoring metric to follow, e.g.
+  `compute.googleapis.com/instance/network/received_bytes_count`
+
+* `type` - Either "cumulative", "delta", or "gauge".
+
+* `target` - The desired metric value per instance. Must be a positive value.
+
+The `load_balancing_utilization` block contains:
+
+* `target` - The floating point threshold where load balancing utilization
+  should be. E.g. if the load balancer's `maxRatePerInstance` is 10 requests
+  per second (RPS) then setting this to 0.5 would cause the group to be scaled
+  such that each instance receives 5 RPS.
+
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following computed attributes are
+exported:
+
+* `self_link` - The URL of the created resource.
+
+## Import
+
+Autoscalers can be imported using the `name`, e.g.
+
+```
+$ terraform import google_compute_region_autoscaler.foobar scaler
+```
