Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as cdk from 'aws-cdk-lib';
const cfnResourceAutoScalingCreationPolicy: cdk.CfnResourceAutoScalingCreationPolicy = {
  minSuccessfulInstancesPercent: 123,
};

Properties

minSuccessfulInstancesPercent?optionalnumbermin_successful_instances_percent?optionalint | floatminSuccessfulInstancesPercent?optionalNumberMinSuccessfulInstancesPercent?optionaldoubleMinSuccessfulInstancesPercent?optional*float64#

Specifies the percentage of instances in an Auto Scaling replacement update that must signal success for the update to succeed.

notes

You can specify a value from 0 to 100. AWS CloudFormation rounds to the nearest tenth of a percent. For example, if you update five instances with a minimum successful percentage of 50, three instances must signal success. If an instance doesn't send a signal within the time specified by the Timeout property, AWS CloudFormation assumes that the instance wasn't created.
