如何通过CloudFormation创建关联SNS Topic的SageMaker训练任务EventBridge规则？

以下是完整的CloudFormation YAML模板，实现你需要的功能：

AWSTemplateFormatVersion: '2010-09-09'
Description: CloudFormation template to create EventBridge Rule for SageMaker Training Job Completed events and target to SNS Topic

Resources:
  # 创建SNS Topic用于接收通知
  SageMakerTrainingCompleteTopic:
    Type: AWS::SNS::Topic
    Properties:
      DisplayName: SageMaker-Training-Job-Complete-Notifications

  # 创建EventBridge规则，匹配SageMaker训练任务完成事件
  SageMakerTrainingCompleteRule:
    Type: AWS::Events::Rule
    Properties:
      Description: Trigger when SageMaker training job completes successfully
      EventPattern:
        source:
          - aws.sagemaker
        detail-type:
          - SageMaker Training Job State Change
        detail:
          TrainingJobStatus:
            - Completed
      State: ENABLED
      Targets:
        - Arn: !Ref SageMakerTrainingCompleteTopic
          Id: SageMakerTrainingCompleteTarget

  # 授予EventBridge权限向SNS Topic发送消息
  SNSTopicPolicy:
    Type: AWS::SNS::TopicPolicy
    Properties:
      PolicyDocument:
        Version: '2012-10-17'
        Statement:
          - Effect: Allow
            Principal:
              Service: events.amazonaws.com
            Action: sns:Publish
            Resource: !Ref SageMakerTrainingCompleteTopic
      Topics:
        - !Ref SageMakerTrainingCompleteTopic

关键部分说明： #

• EventPattern：完全对应你提供的事件模式，确保只捕获SageMaker训练任务进入Completed状态的变更事件
• Targets：将规则与创建的SNS Topic关联，Id是目标的唯一标识（可自定义）
• TopicPolicy：必须配置此权限，否则EventBridge无法向SNS Topic发布消息，导致规则触发失败

你可以根据需要修改资源名称、Topic显示名称等参数，部署此模板后，当SageMaker训练任务完成时，对应的通知会发送到该SNS Topic。
