Overview

Note:

When making an API call, you may pass LifecycleHookSpecification data as a hash:

{
  lifecycle_hook_name: "AsciiStringMaxLen255", # required
  lifecycle_transition: "LifecycleTransition", # required
  notification_metadata: "XmlStringMaxLen1023",
  heartbeat_timeout: 1,
  default_result: "LifecycleActionResult",
  notification_target_arn: "NotificationTargetResourceName",
  role_arn: "XmlStringMaxLen255",
}

Describes information used to specify a lifecycle hook for an Auto Scaling group.

For more information, see Amazon EC2 Auto Scaling lifecycle hooks in the Amazon EC2 Auto Scaling User Guide.
