ModifyLifecycleHook - Auto Scaling - Alibaba Cloud Documentation Center

Modifies a lifecycle hook. If you want to modify a lifecycle hook to better align with your business requirements, you can call the ModifyLifecycleHook operation. This allows you to adjust attributes like the scaling activity type, timeout period, and default action of the lifecycle hook, without the need to delete and recreate it. You can specify the lifecycle hook ID, lifecycle hook name, and scaling group ID to locate the lifecycle hook that you want to modify.

Usage notes

You can use one of the following methods to locate the lifecycle hook that you want to modify:

Specify LifecycleHookId. In this case, ScalingGroupId and LifecycleHookName are ignored.
Specify ScalingGroupId and LifecycleHookName. The name of each lifecycle hook is unique in each scaling group.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter	Type	Required	Example	Description
Action	String	Yes	ModifyLifecycleHook	The operation that you want to perform. Set the value to ModifyLifecycleHook.
LifecycleHookId	String	No	ash-bp1fxuqyi98w0aib****	The ID of the lifecycle hook that you want to modify.
ScalingGroupId	String	No	asg-bp18p2yfxow2dloq****	The ID of the scaling group to which the lifecycle hook belongs.
LifecycleHookName	String	No	test_SCAL****	The name of the lifecycle hook that you want to modify.
DefaultResult	String	No	CONTINUE	The action that Auto Scaling performs after the lifecycle hook times out. Valid values: CONTINUE: Auto Scaling continues to respond to a scale-in or scale-out request. ABANDON: Auto Scaling releases Elastic Compute Service (ECS) instances during scale-out events, or removes ECS instances from the scaling group during scale-in events. ROLLBACK: During scale-in events, Auto Scaling declines requests to release ECS instances and rolls back changes. During scale-out events, the ROLLBACK setting behaves identically to the ABANDON setting. When a scaling group has multiple lifecycle hooks in effect, and you set `DefaultResult` for one of the lifecycle hooks to `ABANDON` or `ROLLBACK`, the following rule applies to scale-in events: If the lifecycle hook with DefaultResult set to ABANDON or ROLLBACK times out, other lifecycle hooks time out ahead of schedule. In other cases, Auto Scaling performs the action only after all lifecycle hooks time out. The action that Auto Scaling performs is determined by the value of DefaultResult that you specify for the lifecycle hook that most recently times out.
HeartbeatTimeout	Integer	No	600	The period of time before the lifecycle hook times out. When the lifecycle hook times out, Auto Scaling performs the action that is specified by DefaultResult. Valid values: 30 to 21600. Unit: seconds. You can call the RecordLifecycleActionHeartbeat operation to extend the timeout period of a lifecycle hook. You can also call the CompleteLifecycleAction operation to end the timeout period of a lifecycle hook ahead of schedule.
LifecycleTransition	String	No	SCALE_IN	The type of the scaling activity to which you want to apply the lifecycle hook. Valid values: SCALE_OUT SCALE_IN
NotificationMetadata	String	No	Test	The fixed string that you want to include in a notification. Each time the lifecycle hook takes effect, Auto Scaling sends a notification. The value of this parameter cannot exceed 4,096 characters in length. Auto Scaling sends the value of `NotificationMetadata` together with the notification. This helps you categorize your notifications. If you specify `NotificationMetadata`, you must specify `NotificationArn`.
NotificationArn	String	No	acs:mns:cn-beijing:161456884340**:queue/modifyLifecycleHo**	The Alibaba Cloud Resource Name (ARN) of the notification recipient. The following list describes the value formats of this parameter: If you specify a Message Service (MNS) queue as the notification recipient, specify the value in the `acs:mns:{region-id}:{account-id}:queue/{queuename}` format. If you specify an MNS topic as the notification recipient, specify the value in the `acs:mns:{region-id}:{account-id}:topic/{topicname}` format. If you specify a CloudOps Orchestration Service (OOS) template as the notification recipient, specify the value in the `acs:oos:{region-id}:{account-id}:template/{templatename}` format. If you specify an event bus provided by EventBridge as the notification recipient, specify the value in the `acs:eventbridge:{region-id}:{account-id}:eventbus/default` format. The variables in the preceding value formats have the following meanings: region-id: the region ID of the scaling group. account-id: the ID of the Alibaba Cloud account. queuename: the name of the MNS queue. topicname: the name of the MNS topic. templatename: the name of the OOS template.
RegionId	String	No	cn-beijing	The region ID of the scaling group.
LifecycleHookStatus	String	No	Active	The status that you want to specify for the lifecycle hook. Valid values: Valid values: Active InActive If you do not specify this parameter, the status of the lifecycle hook remains unchanged after you call this operation. Note By default, a new lifecycle hook automatically enters the Active state.
