Example

declare const vpc: ec2.Vpc;
declare const instanceType: ec2.InstanceType;
declare const machineImage: ec2.IMachineImage;

new autoscaling.AutoScalingGroup(this, 'ASG', {
  vpc,
  instanceType,
  machineImage,

  // ...

  init: ec2.CloudFormationInit.fromElements(
    ec2.InitFile.fromString('/etc/my_instance', 'This got written during instance startup'),
  ),
  signals: autoscaling.Signals.waitForAll({
    timeout: Duration.minutes(10),
  }),
});

Properties

minSuccessPercentage?optionalnumbermin_success_percentage?optionalint | floatminSuccessPercentage?optionalNumberMinSuccessPercentage?optionaldoubleMinSuccessPercentage?optional*float64= 100#

The percentage of signals that need to be successful.

If this number is less than 100, a percentage of signals may be failure signals while still succeeding the creation or update in CloudFormation.

timeout?optionalDurationtimeout?optionalDurationtimeout?optionalDurationTimeout?optionalDurationTimeout?optionalDuration= Duration.minutes(5)#

How long to wait for the signals to be sent.

This should reflect how long it takes your instances to start up (including instance start time and instance initialization time).
