class aws_cdk.aws_autoscaling.CfnLifecycleHookProps(*, auto_scaling_group_name, lifecycle_transition, default_result=None, heartbeat_timeout=None, lifecycle_hook_name=None, notification_metadata=None, notification_target_arn=None, role_arn=None)

Bases: object

Properties for defining a CfnLifecycleHook.

Parameters
  • auto_scaling_group_name (str) – The name of the Auto Scaling group.

  • lifecycle_transition (str) – The lifecycle transition. For Auto Scaling groups, there are two major lifecycle transitions. - To create a lifecycle hook for scale-out events, specify autoscaling:EC2_INSTANCE_LAUNCHING . - To create a lifecycle hook for scale-in events, specify autoscaling:EC2_INSTANCE_TERMINATING .

  • default_result (Optional[str]) – The action the Auto Scaling group takes when the lifecycle hook timeout elapses or if an unexpected failure occurs. The default value is ABANDON . Valid values: CONTINUE | ABANDON

  • heartbeat_timeout (Union[int, float, None]) – The maximum time, in seconds, that can elapse before the lifecycle hook times out. The range is from 30 to 7200 seconds. The default value is 3600 seconds (1 hour).

  • lifecycle_hook_name (Optional[str]) – The name of the lifecycle hook.

  • notification_metadata (Optional[str]) – Additional information that you want to include any time Amazon EC2 Auto Scaling sends a message to the notification target.

  • notification_target_arn (Optional[str]) – The Amazon Resource Name (ARN) of the notification target that Amazon EC2 Auto Scaling sends notifications to when an instance is in a wait state for the lifecycle hook. You can specify an Amazon SNS topic or an Amazon SQS queue.

  • role_arn (Optional[str]) – The ARN of the IAM role that allows the Auto Scaling group to publish to the specified notification target. For information about creating this role, see Configure a notification target for a lifecycle hook in the Amazon EC2 Auto Scaling User Guide . Valid only if the notification target is an Amazon SNS topic or an Amazon SQS queue.
