CloudFormation CloudTrail S3 策略错误 - 为存储桶检测到不正确的 S3 存储桶策略

Question

提前致谢！

我整个周末都被困在这个问题上。我试图在 cloudformation 中创建一个 cloudtrail 服务，但在运行时收到此错误 - 检测到存储桶的 S3 存储桶策略不正确：s3bucket-xxxxxx

这是我的代码；

"s3bucket-xxxxxx": {
    "Type": "AWS::S3::Bucket",
    "Properties": {
        "AccessControl": "Private",
        "VersioningConfiguration": {

                },
                {

                        }
                    }
                }
            ]

要解决此问题，需要使用引用将资源加入存储桶

                    "Resource": [{
                      "Fn::Join": [ "", [
                          "arn:aws:s3:::", {
                            "Ref": "s3traillogs"
                          }, "/AWSLogs/XXXXXXXXXXX/*"
                        ]
                      ]
                    }],

根据资源定义，YAML 可能如下：

  EventBucketStorage:
    Type: "AWS::S3::Bucket"
    Properties:
      #AccessControl: PublicRead
      MetricsConfigurations:
        - Id: EventBucketStorageMetrics
      BucketName: !Sub "s3-event-step-bucket-storage-s"

  EventBucketPolicy:
    Type: AWS::S3::BucketPolicy
    Properties:
      Bucket: !Ref EventBucketStorage
      PolicyDocument:
        Version: 2012-10-17
        Statement:
          - 
            Sid: "AWSCloudTrailAclCheck20150319"
            Effect: Allow
            Principal:
              Service: cloudtrail.amazonaws.com
            Action: s3:GetBucketAcl
            Resource: !Join
              - ""
              - - "arn:aws:s3:::"
                - !Ref EventBucketStorage              
          - 
            Sid: AWSCloudTrailWrite20150319
            Effect: Allow
            Principal:
              Service: cloudtrail.amazonaws.com
            Action: s3:PutObject
            Resource: !Join
              - ""
              - - "arn:aws:s3:::"
                - !Ref EventBucketStorage
                - /*
            Condition:
              StringEquals:
                s3:x-amz-acl: bucket-owner-full-control

提到的错误也可能是由于：

1 ) trail 和 bucket 之间的依赖问题。

这可以通过引用跟踪中的桶来解决：

   "DependsOn": [
        "TheLogBucket"
    ]

2 ) 存储桶策略配置错误。

例如，在第二个语句中："Resource":"arn:aws:s3:::myBucketName/<prefix>/AWSLogs/<account-id>/*"
传递了错误的前缀、帐户 ID 或忘记了 "*" 后缀。

3 ) YAML 文件中的错误缩进或错误的引号。

(*)#1 和#2 的问题也提到了here。
