Register Lifecycle Hook and Complete Action

with Amazon EC2 Auto Scaling

Create a lifecycle hook, verify it, and complete a pending lifecycle action.

  1. Create or update the lifecycle hook on the Auto Scaling group.
  2. Describe the group's lifecycle hooks to confirm the new hook is registered and capture its transition and timeout.
  3. Complete a pending lifecycle action for the instance with the supplied result so the instance can proceed.
What you'll need to have ready
  • autoScalingGroupName: The name of the Auto Scaling group.
  • lifecycleHookName: The name of the lifecycle hook.
  • lifecycleTransition: The lifecycle transition (autoscaling:EC2_INSTANCE_LAUNCHING or autoscaling:EC2_INSTANCE_TERMINATING).
  • roleArn: The ARN of the IAM role that allows the group to publish to the notification target.
  • notificationTargetArn: The ARN of the Amazon SNS topic or SQS queue notification target.
