data字段包含的参数解释如下表所示。

参数

类型

示例值

描述

instanceIds

Array

[ "i-xxx" ]

缩容实例ID列表。

lifecycleHookId

String

ash-xxx

生命周期挂钩ID。

lifecycleActionToken

String

XXXX

伸缩活动的等待状态标识符。

scalingGroupId

String

asg-xxx

伸缩组ID。

scalingActivityId

String

asa-xxx

伸缩活动ID。

notificationMetadata

String

lifecycleHook metadata example

生命周期挂钩通知信息。

defaultResult

String

CONTINUE

生命周期挂钩默认结果。取值如下：

  • CONTINUE：继续响应弹性扩张活动或者继续响应弹性收缩活动。

  • ABANDON：直接释放弹性扩张活动创建出来的ECS实例或者直接将弹性收缩活动中的ECS实例从伸缩组移除。

  • ROLLBACK：针对弹性收缩活动，会拒绝释放ECS实例，进行回滚；针对弹性扩张活动，会直接释放创建出来的ECS实例，效果同ABANDON一样。
