适用于 Amazon ECS/ 的 IAM 政策AWS Fargate

以下示例模板展示了如何根据状态机定义中的资源 AWS Step Functions 生成 IAM 策略。有关更多信息，请参阅 集成服务的 IAM 策略 和 服务集成模式。

由于在提交任务之前 TaskId 的值始终是未知的，因此 Step Functions 会创建具有更高特权的 "Resource": "*" 策略。

注意

尽管有 "*" IAM 策略，但您只能停止由 Step Functions 启动的 Amazon Elastic Container Service (Amazon ECS) 任务。

如果您计划的 Amazon ECS 任务需要使用任务执行角色、任务角色或任务角色覆盖，则必须将每个任务执行角色、任务角色或任务角色覆盖的iam:PassRole权限添加到调用实体的 Ev CloudWatch ents IAM 角色（在本例中为 Step Functions）中。
