PolicyArgs

data class PolicyArgs(val adjustmentType: Output<String>? = null, val autoscalingGroupName: Output<String>? = null, val cooldown: Output<Int>? = null, val enabled: Output<Boolean>? = null, val estimatedInstanceWarmup: Output<Int>? = null, val metricAggregationType: Output<String>? = null, val minAdjustmentMagnitude: Output<Int>? = null, val name: Output<String>? = null, val policyType: Output<String>? = null, val predictiveScalingConfiguration: Output<PolicyPredictiveScalingConfigurationArgs>? = null, val scalingAdjustment: Output<Int>? = null, val stepAdjustments: Output<List<PolicyStepAdjustmentArgs>>? = null, val targetTrackingConfiguration: Output<PolicyTargetTrackingConfigurationArgs>? = null) : ConvertibleToJava<PolicyArgs>

Provides an AutoScaling Scaling Policy resource.

NOTE: You may want to omit desired_capacity attribute from attached aws.autoscaling.Group when using autoscaling policies. It's good practice to pick either manual or dynamic (policy-based) scaling.

Import

AutoScaling scaling policy can be imported using the role autoscaling_group_name and name separated by /.

$ pulumi import aws:autoscaling/policy:Policy test-policy asg-name/policy-name

Constructors

PolicyArgs

constructor(adjustmentType: Output<String>? = null, autoscalingGroupName: Output<String>? = null, cooldown: Output<Int>? = null, enabled: Output<Boolean>? = null, estimatedInstanceWarmup: Output<Int>? = null, metricAggregationType: Output<String>? = null, minAdjustmentMagnitude: Output<Int>? = null, name: Output<String>? = null, policyType: Output<String>? = null, predictiveScalingConfiguration: Output<PolicyPredictiveScalingConfigurationArgs>? = null, scalingAdjustment: Output<Int>? = null, stepAdjustments: Output<List<PolicyStepAdjustmentArgs>>? = null, targetTrackingConfiguration: Output<PolicyTargetTrackingConfigurationArgs>? = null)

Properties

adjustmentType

val adjustmentType: Output<String>? = null

Whether the adjustment is an absolute number or a percentage of the current capacity. Valid values are ChangeInCapacity, ExactCapacity, and PercentChangeInCapacity.

autoscalingGroupName

val autoscalingGroupName: Output<String>? = null

Name of the autoscaling group.

cooldown

val cooldown: Output<Int>? = null

Amount of time, in seconds, after a scaling activity completes and before the next scaling activity can start.

enabled

val enabled: Output<Boolean>? = null

Whether the scaling policy is enabled or disabled. Default: true. The following argument is only available to "SimpleScaling" and "StepScaling" type policies:

estimatedInstanceWarmup

val estimatedInstanceWarmup: Output<Int>? = null

Estimated time, in seconds, until a newly launched instance will contribute CloudWatch metrics. Without a value, AWS will default to the group's specified cooldown period.

metricAggregationType

val metricAggregationType: Output<String>? = null

Aggregation type for the policy's metrics. Valid values are "Minimum", "Maximum", and "Average". Without a value, AWS will treat the aggregation type as "Average".

minAdjustmentMagnitude

val minAdjustmentMagnitude: Output<Int>? = null

Minimum value to scale by when adjustment_type is set to PercentChangeInCapacity. The following arguments are only available to "SimpleScaling" type policies:

name

val name: Output<String>? = null

Name of the policy.

policyType

val policyType: Output<String>? = null

Policy type, either "SimpleScaling", "StepScaling", "TargetTrackingScaling", or "PredictiveScaling". If this value isn't provided, AWS will default to "SimpleScaling."

predictiveScalingConfiguration

val predictiveScalingConfiguration: Output<PolicyPredictiveScalingConfigurationArgs>? = null

Predictive scaling policy configuration to use with Amazon EC2 Auto Scaling.

scalingAdjustment

val scalingAdjustment: Output<Int>? = null

Number of members by which to scale, when the adjustment bounds are breached. A positive value scales up. A negative value scales down.

stepAdjustments

val stepAdjustments: Output<List<PolicyStepAdjustmentArgs>>? = null

Set of adjustments that manage group scaling. These have the following structure:

targetTrackingConfiguration

val targetTrackingConfiguration: Output<PolicyTargetTrackingConfigurationArgs>? = null

Target tracking policy. These have the following structure:
