# Amazon ECS 任务状态更改事件 以下方案将引起任务状态更改事件： 您调用 `StartTask`、`RunTask` 或 `StopTask` API 操作（直接调用，或者通过 AWS 管理控制台、AWS CLI 或开发工具包调用）。 启动或停止任务将创建新的任务资源或修改现有任务资源的状态。 Amazon ECS 服务调度器启动或停止任务。 启动或停止任务将创建新的任务资源或修改现有任务资源的状态。 Amazon ECS 容器代理调用 `SubmitTaskStateChange` API 操作。 对于 EC2，Amazon ECS 容器代理将监控容器实例上的任务的状态。Amazon ECS 容器代理将报告任何状态更改。状态更改可能包括从 `PENDING` 到 `RUNNING` 或从 `RUNNING` 到 `STOPPED` 的更改。 您可以使用 `DeregisterContainerInstance` API 操作和 `force` 标志（直接调用，或者通过 AWS 管理控制台或开发工具包调用）强制取消注册基础容器实例。 注销容器实例将更改容器实例的状态以及 Amazon ECS 容器代理的连接状态。如果任务正在容器实例上运行，则必须设置 `force` 标志以允许取消注册。这将停止实例上的所有任务。 停止或终止基础容器实例。 在停止或终止容器实例时，该实例上运行的任务会转换为 `STOPPED` 状态。 任务中的容器状态发生更改。 Amazon ECS 容器代理监控任务中的容器状态。例如，如果在任务中运行的容器停止，则此容器状态更改将生成事件。 使用 Fargate Spot 容量提供程序的任务会收到终止通知。 当任务正在使用 `FARGATE_SPOT` 容量提供程序并且由于 Spot 中断而停止时会生成任务状态更改事件。 **Example 任务状态更改事件** 任务状态更改事件以下面的形式传送。请注意有关字段的以下内容： + 任务状态更改事件中未提供事件的运行状况。如果需要任务运行状况，则可以运行 [describe-tasks](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_DescribeTasks.html)。 + 当容器使用通过 Amazon ECR 托管的映像时，将返回 `imageDigest` 字段。 + `createdAt`、`connectivityAt`、`pullStartedAt`、`startedAt`、`pullStoppedAt` 和 `updatedAt` 字段的值是 ISO 字符串时间戳。 + `detail-type` 值为“ECS 任务状态更改”。 + 当为已停止的任务生成事件时，`stoppedReason` 和 `stopCode` 字段会提供有关任务停止原因的其他信息（例如“用户启动”）。 有关 EventBridge 参数的更多信息，请参阅《*Amazon EventBridge 事件参考*》中的 [AWS service event metadata](https://docs.aws.amazon.com/eventbridge/latest/ref/events-structure.html)。 有关如何配置一个仅捕获其中的任务因某个主要容器终止而停止的任务事件的 Amazon EventBridge 事件规则，请参阅 [针对 Amazon ECS 任务停止事件发送 Amazon
