    10  
    11  Provides an AutoScaling Scaling Policy resource.
    12  
    13  ~> **NOTE:** You may want to omit `desired_capacity` attribute from attached `aws_autoscaling_group`
    14  when using autoscaling policies. It's good practice to pick either
    15  [manual](http://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/as-manual-scaling.html)
    16  or [dynamic](http://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/as-scale-based-on-demand.html)
    17  (policy-based) scaling.
    18  
    19  ## Example Usage
    20  ```
    21  resource "aws_autoscaling_policy" "bat" {
    22    name = "foobar3-terraform-test"
    23    scaling_adjustment = 4
    24    adjustment_type = "ChangeInCapacity"
    25    cooldown = 300
    26    autoscaling_group_name = "${aws_autoscaling_group.bar.name}"
    27  }
    28  
    29  resource "aws_autoscaling_group" "bar" {
    30    availability_zones = ["us-east-1a"]
    31    name = "foobar3-terraform-test"
    32    max_size = 5
    33    min_size = 2
    34    health_check_grace_period = 300
    35    health_check_type = "ELB"
    36    force_delete = true
    37    launch_configuration = "${aws_launch_configuration.foo.name}"
    38  }
    39  ```

    41  ## Argument Reference
    42  
    43  The following arguments are supported:
    44  
    45  * `name` - (Required) The name of the policy.
    46  * `autoscaling_group_name` - (Required) The name or ARN of the group.
    47  * `adjustment_type` - (Required) Specifies whether the `scaling_adjustment` is an absolute number or a percentage of the current capacity. Valid values are `ChangeInCapacity`, `ExactCapacity`, and `PercentChangeInCapacity`.
    48  * `scaling_adjustment` - (Required) The number of instances by which to scale. `adjustment_type` determines the interpretation of this number (e.g., as an absolute number or as a percentage of the existing Auto Scaling group size). A positive increment adds to the current capacity and a negative value removes from the current capacity.
    49  * `cooldown` - (Optional) The amount of time, in seconds, after a scaling activity completes and before the next scaling activity can start.
    50  * `min_adjustment_step` - (Optional) Used with `adjustment_type` with the value `PercentChangeInCapacity`, the scaling policy changes the `desired_capacity` of the Auto Scaling group by at least the number of instances specified in the value.
    51  
    52  ## Attribute Reference
    53  * `arn` - The ARN assigned by AWS to the scaling policy.
