declare const machineImage: ec2.IMachineImage;

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

  // ...

  init: ec2.CloudFormationInit.fromElements(
    ec2.InitFile.fromString('/etc/my_instance', 'This got written during instance startup'),
  ),

---

minSuccessPercentage?

Type: number (optional, default: 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?

Type: Duration (optional, default: 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).
