If an existing lifecycle hook does not meet your business requirements anymore, you can call the ModifyLifecycleHook operation to modify the information such as the scaling event, timeout period, and default action of the lifecycle hook. Before you modify a lifecycle hook, you can locate the lifecycle hook by its ID, name, or scaling group.
Operation description

- Specify LifecycleHookId. In this case, ScalingGroupId and LifecycleHookName are ignored.
- Specify ScalingGroupId and LifecycleHookName. Each lifecycle hook within a scaling group has a unique name.

Request parameters
Parameter | Type | Required | Description | Example |
---|---|---|---|---|
LifecycleHookId | string | No | The ID of the lifecycle hook that you want to modify. | ash-bp1fxuqyi98w0aib**** |

LifecycleHookName | string | No | The name of the lifecycle hook that you want to modify. | test_SCALE_IN |
DefaultResult | string | No | The action that you want Auto Scaling to perform after the lifecycle hook ends. Valid values:
If multiple lifecycle hooks in a scaling group are triggered during scale-in activities and you set the DefaultResult parameter to ABANDON for the lifecycle hook that you want to modify, Auto Scaling immediately performs the action after the lifecycle hook that you want to modify ends. As a result, other lifecycle hooks end ahead of schedule. In other cases, Auto Scaling performs the action only after all lifecycle hooks end. | CONTINUE |
HeartbeatTimeout | integer | No | The period of time before the lifecycle hook ends. Auto Scaling performs the specified action after the lifecycle hook ends. Valid values: 30 to 21600. Unit: seconds. You can call the RecordLifecycleActionHeartbeat operation to prolong the length of a lifecycle hook. You can also call the CompleteLifecycleAction operation to end a lifecycle hook ahead of schedule. | 600 |
LifecycleTransition | string | No | The type of scaling activity to which the lifecycle hook applies. Valid values:
| SCALE_IN |
NotificationMetadata | string | No | The fixed string that is included in a notification. Auto Scaling sends the notification when the lifecycle hook takes effect. The value of this parameter cannot exceed 4,096 characters in length. Auto Scaling sends the value specified for the NotificationMetadata parameter together with the notification. This helps you categorize your notifications. The NotificationMetadata parameter takes effect only after you specify the NotificationArn parameter. | Test |
NotificationArn | string | No | The Alibaba Cloud Resource Name (ARN) of the notification method. Specify the value in one of the following formats:
The variables in the preceding parameter formats have the following meanings:
| acs:mns:cn-beijing:161456884340****:queue/modifyLifecycleHo**** |
