aws-cloudformation - 云信息 : How to append properties to a pre-defined bucket?

Question

我有一个定义 s3 存储桶的模板。我无法修改模板。我只能向模板添加额外的信息。如何向预定义的 s3 存储桶添加加密？

Resources:
    s3Bucket:
        Type: "AWS::S3::Bucket"
        Properties:
            BucketName: "my pre-defined bucket"
    # I want to write something like below code. I can get a reference of the pre-defined bucket then add encryption
    s3BucketEncryption:
        Type: "AWS::S3::Bucket"
        Properties:
            BucketName: !Ref s3Bucket  
            BucketEncryption: 
              ServerSideEncryptionConfiguration: 
               - ServerSideEncryptionByDefault:
                 SSEAlgorithm: AES256

您可以import existing resources into CloudFormation现在。这允许您将对在 CloudFormation 外部创建的存储桶进行控制，从而允许您更改其属性。
