• heartbeat_timeout - (Optional) Defines the amount of time, in seconds, that can elapse before the lifecycle hook times out. When the lifecycle hook times out, Auto Scaling performs the action defined in the default_result parameter. Default value: 600.
• default_result - (Optional) Defines the action the Auto Scaling group should take when the lifecycle hook timeout elapses. Applicable value: CONTINUE, ABANDON, ROLLBACK, default value: CONTINUE.
• notification_arn - (Optional) The Arn of notification target.
• notification_metadata - (Optional) Additional information that you want to include when Auto Scaling sends a message to the notification target.

Attribute Reference

The following attributes are exported:

• id - The ID of lifecycle hook.
• scaling_group_id - The scalingGroupId to which lifecycle belongs.
• name - The name of lifecycle hook.
• default_result - The action the Auto Scaling group should take when the lifecycle hook timeout elapses.
• heartbeat_timeout - The amount of time that can elapse before the lifecycle hook time out.
• lifecycle_transition - Type of Scaling activity attached to lifecycle hook.
• notification_metadata - Additional information that will be sent to notification target.
• notification_arn - The arn of notification target.

Import

Ess lifecycle hook can be imported using the id, e.g.
