Question

我正在尝试使用2种不同的策略创建2个存储桶。

一个桶，VendorsWGLogs，将成为日志输出的目的地。

另一个存储桶VendorsWG将授予GetObject，PutObject和DeleteObject访问指定IAM组的权限。

这是我到目前为止所做的：

"Resources": {
    "VendorsWGLogs": {
      "Type": "AWS::S3::Bucket",
      "Properties": {},
    },
    "LogsBucketPolicy": {
      "Type": "AWS::S3::BucketPolicy",
      "Properties": {
        "Bucket": {
          "Ref": "VendorsWGLogs"
        },
        "PolicyDocument": {
          "Version": "2012-10-17",
          "Statement": [
            {
              "Sid": "WeatherGuidance LogBucket permissions",
              "Effect": "Allow",
              "Principal": {
                "AWS" : "arn:aws:s3:::VendorsWG"
              },
              "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:PutObjectAcl"
              ],
              "Resource" : { "Fn::Join" : [
                  "", [ "arn:aws:s3:::", { "Ref" : "VendorsWGLogs" } , "/*" ]
               ]}
            }
          ]
        }
      }
    },
    "VendorsWG": {
      "Type": "AWS::S3::Bucket",
      "Properties": {
        "LoggingConfiguration": {
          "DestinationBucketName": {"Ref" : "VendorsWGLogs"},
          "LogFilePrefix": "testing-logs"
        }
      },
      "Metadata": {
        "AWS::CloudFormation::Designer": {
          "id": "a1169860-d743-406e-a3e5-e12831826439"
        },
      }
    },
    "S3BP4TNQZ": {
      "Type": "AWS::S3::BucketPolicy",
      "Properties": {
        "Bucket": {
          "Ref": "VendorsWG"
        },
        "PolicyDocument": {
          "Version": "2012-10-17",
          "Statement": [
            {
              "Sid": "WeatherGuidance Object permissions",
              "Effect": "Allow",
              "Principal": {
                "AWS" : "arn:aws:iam::someUserGroup"
              },
              "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
              ],
              "Resource" : { "Fn::Join" : [
                  "", [ "arn:aws:s3:::", { "Ref" : "VendorsWG" } , "/*" ]
               ]}
            },
            {
              "Sid": "WeatherGuidance ListBucket",
              "Effect": "Allow",
              "Principal": {
                "AWS" : "arn:aws:iam::someUserGroup"
              },
              "Action": "s3:ListBucket",
              "Resource" : { "Fn::Join" : [
                  "", [ "arn:aws:s3:::", { "Ref" : "VendorsWG" } ]
               ]},
              "Condition": {
                "StringLike": {
                  "s3:prefix": "weatherguidance*"
                }
              }
            }
          ]
        }
      }
    }
  }

当我尝试创建堆栈时，我收到此错误

事件日志输出：

类型：

AWS::S3::Bucket

逻辑ID：

VendorsWG

身份原因：

You must give the log-delivery group WRITE and READ_ACP permissions to the target bucket

我认为将目标存储桶的策略主体指定为VendorsWGLogs会解决这个问题，现在我已经没有想法了。

我做错了什么？如何启用日志记录？感谢

Answer 1

需要将其置于日志存储桶属性

下

Properties: {
      AccessControl: "LogDeliveryWrite"
}

Answer 2

我认为你的问题有两个方面：

操作中没有s3:ListBucket因此无法读取存储桶的内容
对s3存储桶的操作在存储桶（VendorsWGLogs）和内容（VendorsWGLogs/*）级别运行，因此需要在资源下列出这两个存储桶。由此产生的政策应为

＆＃34;资源＆＃34;：[ ＆＃34; ARN：AWS：S3 ::: VendorsWGLogs＆＃34 ;, ＆＃34; ARN：AWS：S3 ::: VendorsWGLogs / *＆＃34; ]

通过cloudFormation模板启用日志记录S3？
