aws_application_autoscaling_scaling

Use the aws_application_autoscaling_scaling_policy InSpec audit resource to test properties of a single AWS Application Auto Scaling scaling policy.

For additional information, including details on parameters and properties, see the AWS ApplicationAutoScaling ScalingPolicy documentation.

Installation

This resource is available in the Chef InSpec AWS resource pack.

See the Chef InSpec documentation on cloud platforms for information on configuring your AWS environment for InSpec and creating an InSpec profile that uses the InSpec AWS resource pack.

Syntax

Ensure a scaling policy exists.

describe aws_application_autoscaling_scaling_policy( service_namespace: 'SERVICE_NAMESPACE' ) do
  it { should exist }
end

Parameters

service_namespace (required): The namespace of the AWS service that provides the resource, or a custom-resource.

Properties

policy_arn: The Amazon Resource Name (ARN) of the scaling policy.
policy_name: The name of the scaling policy.
service_namespace: The namespace of the AWS service that provides the resource, or a custom-resource.
resource_id: The identifier of the resource associated with the scaling policy. This string consists of the resource type and unique identifier.
scalable_dimension: The scalable dimension. This string consists of the service namespace, resource type, and scaling property.
policy_type: The Application Auto Scaling policy type.
step_scaling_policy_configuration (adjustment_type): Specifies how the ScalingAdjustment value in a StepAdjustment is interpreted (for example, an absolute number or a percentage). The valid values are ChangeInCapacity , ExactCapacity , and PercentChangeInCapacity.
step_scaling_policy_configuration (step_adjustments): A set of adjustments that enable you to scale based on the size of the alarm breach.
step_scaling_policy_configuration (step_adjustments (metric_interval_lower_bound)): The lower bound for the difference between the alarm threshold and the CloudWatch metric.
step_scaling_policy_configuration (step_adjustments (metric_interval_upper_bound)): The upper bound for the difference between the alarm threshold and the CloudWatch metric.
step_scaling_policy_configuration (step_adjustments (scaling_adjustment)): The amount by which to scale, based on the specified adjustment type.
step_scaling_policy_configuration (min_adjustment_magnitude): The minimum value to scale by when the adjustment type is PercentChangeInCapacity.
step_scaling_policy_configuration (cooldown): The amount of time, in seconds, to wait for a previous scaling activity to take effect.
step_scaling_policy_configuration (metric_aggregation_type): The aggregation type for the CloudWatch metrics. Valid values are Minimum, Maximum, and Average.
target_tracking_scaling_policy_configuration (target_value): The target value for the metric.
target_tracking_scaling_policy_configuration (predefined_metric_specification (predefined_metric_type)): The metric type. The ALBRequestCountPerTarget metric type applies only to Spot Fleet requests and ECS services.
target_tracking_scaling_policy_configuration (predefined_metric_specification (resource_label)): Identifies the resource associated with the metric type. You can’t specify a resource label unless the metric type is ALBRequestCountPerTarget and there is a target group attached to the Spot Fleet request or ECS service.
target_tracking_scaling_policy_configuration (customized_metric_specification (metric_name)): The name of the metric.
target_tracking_scaling_policy_configuration (customized_metric_specification (namespace)): The namespace of the metric.
target_tracking_scaling_policy_configuration (customized_metric_specification (dimensions (name))): The name of the dimension.
target_tracking_scaling_policy_configuration (customized_metric_specification (dimensions (value))): The value of the dimension.
target_tracking_scaling_policy_configuration (customized_metric_specification (statistic)): The statistic of the metric.
target_tracking_scaling_policy_configuration (customized_metric_specification (unit)): The unit of the metric.
target_tracking_scaling_policy_configuration (scale_out_cooldown): The amount of time, in seconds, to wait for a previous scale-out activity to take effect.
target_tracking_scaling_policy_configuration (scale_in_cooldown): The amount of time, in seconds, after a scale-in activity completes before another scale-in activity can start.
target_tracking_scaling_policy_configuration (disable_scale_in): Indicates whether scale in by the target tracking scaling policy is disabled.
alarms (alarm_name): The name of the alarm.
alarms (alarm_arn): The Amazon Resource Name (ARN) of the alarm.
creation_time: The Unix timestamp for when the scaling policy was created.

Examples

Ensure a policy name is available.

describe aws_application_autoscaling_scaling_policy( service_namespace: 'SERVICE_NAMESPACE' ) do
  its('policy_name') { should eq 'POLICY_NAME' }
end

Ensure a policy type is available.

describe aws_application_autoscaling_scaling_policy( service_namespace: 'SERVICE_NAMESPACE' ) do
    its('policy_type') { should eq "POLICY_TYPE" }
end

Matchers

This InSpec audit resource has the following special matchers. For a full list of available matchers, please visit our Universal Matchers page.

The controls will pass if the describe method returns at least one result.

exist

Use should to test that the entity exists.

describe aws_application_autoscaling_scaling_policy( service_namespace: 'SERVICE_NAMESPACE' ) do
  it { should exist }
end

be_available

Use should to check if the scalable policy is available.

describe aws_application_autoscaling_scaling_policy( service_namespace: 'SERVICE_NAMESPACE' ) do
  it { should be_available }
end

AWS Permissions

Your Principal will need the ApplicationAutoScaling:Client:DescribeScalingPoliciesResponse action with Effect set to Allow.
