aws autoscaling put-scaling-policy
Creates or updates a scaling policy for an Auto Scaling group. For more information about using scaling policies to scale your Auto Scaling group, see Target tracking scaling policies and Step and simple scaling policies in the Amazon EC2 Auto Scaling User Guide
Options
| Name | Description |
|---|---|
--auto-scaling-group-name <string> | The name of the Auto Scaling group |
--policy-name <string> | The name of the policy |
--policy-type <string> | One of the following policy types: TargetTrackingScaling StepScaling SimpleScaling (default) |
--adjustment-type <string> | Specifies how the scaling adjustment is interpreted (for example, an absolute number or a percentage). The valid values are ChangeInCapacity, ExactCapacity, and PercentChangeInCapacity. Required if the policy type is StepScaling or SimpleScaling. For more information, see Scaling adjustment types in the Amazon EC2 Auto Scaling User Guide |
--min-adjustment-step <integer> | Available for backward compatibility. Use MinAdjustmentMagnitude instead |
--min-adjustment-magnitude <integer> | The minimum value to scale by when the adjustment type is PercentChangeInCapacity. For example, suppose that you create a step scaling policy to scale out an Auto Scaling group by 25 percent and you specify a MinAdjustmentMagnitude of 2. If the group has 4 instances and the scaling policy is performed, 25 percent of 4 is 1. However, because you specified a MinAdjustmentMagnitude of 2, Amazon EC2 Auto Scaling scales out the group by 2 instances. Valid only if the policy type is StepScaling or SimpleScaling. For more information, see Scaling adjustment types in the Amazon EC2 Auto Scaling User Guide. Some Auto Scaling groups use instance weights. In this case, set the MinAdjustmentMagnitude to a value that is at least as large as your largest instance weight |
--scaling-adjustment <integer> | The amount by which to scale, based on the specified adjustment type. A positive value adds to the current capacity while a negative number removes from the current capacity. For exact capacity, you must specify a positive value. Required if the policy type is SimpleScaling. (Not used with any other policy type.) |
--cooldown <integer> | The duration of the policy's cooldown period, in seconds. When a cooldown period is specified here, it overrides the default cooldown period defined for the Auto Scaling group. Valid only if the policy type is SimpleScaling. For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide |
--metric-aggregation-type <string> | The aggregation type for the CloudWatch metrics. The valid values are Minimum, Maximum, and Average. If the aggregation type is null, the value is treated as Average. Valid only if the policy type is StepScaling |
--step-adjustments <list> | A set of adjustments that enable you to scale based on the size of the alarm breach. Required if the policy type is StepScaling. (Not used with any other policy type.) |
--estimated-instance-warmup <integer> | The estimated time, in seconds, until a newly launched instance can contribute to the CloudWatch metrics. If not provided, the default is to use the value from the default cooldown period for the Auto Scaling group. Valid only if the policy type is TargetTrackingScaling or StepScaling |
--target-tracking-configuration <structure> | A target tracking scaling policy. Includes support for predefined or customized metrics. The following predefined metrics are available: ASGAverageCPUUtilization ASGAverageNetworkIn ASGAverageNetworkOut ALBRequestCountPerTarget If you specify ALBRequestCountPerTarget for the metric, you must specify the ResourceLabel parameter with the PredefinedMetricSpecification. For more information, see TargetTrackingConfiguration in the Amazon EC2 Auto Scaling API Reference. Required if the policy type is TargetTrackingScaling |
--enabled | Indicates whether the scaling policy is enabled or disabled. The default is enabled. For more information, see Disabling a scaling policy for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide |
--no-enabled | Indicates whether the scaling policy is enabled or disabled. The default is enabled. For more information, see Disabling a scaling policy for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide |
--cli-input-json <string> | Performs service operation based on the JSON string provided. The JSON string follows the format provided by ``--generate-cli-skeleton``. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally |
--generate-cli-skeleton <string> | Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value ``input``, prints a sample input JSON that can be used as an argument for ``--cli-input-json``. If provided with the value ``output``, it validates the command inputs and returns a sample output JSON for that command |
