通过 cloudFormation 模板启用日志记录 S3？

Question

我正在尝试使用 2 个不同的策略创建 2 个存储桶。

一个桶，VendorsWGLogs，将是日志输出的目的地。

另一个存储桶 VendorsWG 将授予 GetObject、PutObject 和 DeleteObject 对指定 IAM 组的访问权限。

这是我目前所拥有的：

"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   

状态原因：

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 可以解决此问题，但现在我没有想法了。

我做错了什么？我可以做些什么来启用日志记录？ 谢谢

Answer 1

需要把它放在日志桶的属性下

Properties: {
      AccessControl: "LogDeliveryWrite"
}

Answer 2

我认为你的问题有两个方面：

1. 动作中没有s3:ListBucket，因此无法读取存储桶的内容

2. s3 存储桶上的操作在存储桶 (VendorsWGLogs) 和内容 (VendorsWGLogs/*) 级别运行，因此您需要将它们都列在资源下。生成的策略应为

   “资源”：[ "arn:aws:s3:::VendorsWGLogs", “arn:aws:s3:::VendorsWGLogs/*” ]
