DeleteLifecycleHook - Auto Scaling - Alibaba Cloud Documentation Center

Deletes a lifecycle hook. If you do not require a lifecycle hook, you can call the DeleteLifecycleHook operation to delete it.

Usage notes

If you delete a lifecycle hook that is in effect in a scaling group, instances on which the lifecycle hook takes effect exit the Pending state ahead of schedule. You can use one of the following methods to specify the lifecycle hooks that you want to delete:

Specify the lifecycle hook ID by using LifecycleHookId. In this case, ScalingGroupId and LifecycleHookName are ignored.
Specify the scaling group ID by using ScalingGroupId and specify the lifecycle hook name by using LifecycleHookName.
