amazon-web-services - 如何将现有存储桶的 S3 触发器添加到 cloudformation 中的 lambda 函数

Question

我正在尝试为 lambda 函数管道创建一个 template.yml，这是我的模板：

AWSTemplateFormatVersion: "2010-09-09"
Transform: AWS::Serverless-2016-10-31

Parameters:
  ImageUri:
    Type: String
  LambdaName: 
    Type: String
  RoleName:
    Type: String
  BucketName:
    Type: String
    
Resources:
  S3Bucket:
    Type: AWS::S3::Bucket
    DeletionPolicy: Retain            
    Properties:
      BucketName: !Ref BucketName

  AllowS3ToCallLambdaPermission:
    Type: AWS::Lambda::Permission
    Properties:
      Action: lambda:InvokeFunction
      FunctionName: !Ref LambdaFunction
      Principal: s3.amazonaws.com
      SourceArn: !GetAtt S3Bucket.Arn

  LambdaRole:
    Type: AWS::IAM::Role
    Properties:
      RoleName: !Ref RoleName
      AssumeRolePolicyDocument:
        Statement:
          - Action:
            - sts:AssumeRole
            Effect: Allow
            Principal:
              Service:
              - lambda.amazonaws.com
        Version: 2012-10-17
      ManagedPolicyArns:
        - arn:aws:iam::aws:policy/AmazonS3FullAccess

  LambdaFunction:
    Type: AWS::Serverless::Function
    Properties:
      FunctionName: !Ref LambdaName
      PackageType: Image
      MemorySize: 256
      Timeout: 5
      ImageUri: !Ref ImageUri
      Events:
        S3Bucket:
          Type: S3
          Properties:
            Bucket: !Ref S3Bucket
            Events: 's3:ObjectCreated:*'
      Role:
        Fn::GetAtt:
          - LambdaRole
          - Arn

此模板包含一个 S3 事件，上面的模板尝试创建一个新存储桶。有没有办法为触发器指定一个现有的存储桶？

无论我如何尝试LambdaFunction使用现有的 S3 存储桶来获取资源，我都失败了。
