Question

我正在尝试使用Go SDK创建一个cloudtrail。通过遵循AWS文档成功连接AWS而没有任何问题。

我按照以下步骤创建了一个跟踪

步骤1 - 创建S3 Bucket，以便可以将所有跟踪日志文件放在此存储桶中。

CreateS3Bucket：代码

func CreateS3Bucket(bucketName string) error {
bucketName := "s3-bucket-123"
svc := s3.New(session.New(&aws.Config{Region: aws.String("us-east-1")}))

params := &s3.CreateBucketInput{
    Bucket: aws.String(bucketName), // Required
}
resp, err1 := svc.CreateBucket(params)

if err1 != nil {
    // Print the error, cast err to awserr.Error to get the Code and
    // Message from an error.
    log.Errorf("S3 Bucket Creation Fails: %s", err1.Error())
    errs := errors.New("500")
    return errs
}

// Pretty-print the response data.
log.Infof("Bucket Successfully created: %s", resp)
return nil
}

成功回应：

{\n  Location: \"/s3-bucket-123\"\n}"

Step2 - 创建CloudTrail

CreateCloudTrail： 代码

func (ref *AwsCloudTrail) CreateCloudTrail(bucketName, trailName string) error {
svc := cloudtrail.New(session.New(&aws.Config{Region: aws.String("us-east-1")}))

//bucketName is "s3-bucket-123" and trailName is cloudtrail123

params := &cloudtrail.CreateTrailInput{
    Name:                       aws.String(trailName), // Required
    S3BucketName:               aws.String(bucketName), // Required
}

resp, errs := svc.CreateTrail(params)

if errs != nil {
    // Print the error, cast err to awserr.Error to get the Code and
    // Message from an error.
    log.Errorf("Error while creating trail %v",errs.Error())
    err := errors.New("500")
    return err
}

// Pretty-print the response data.
log.Infof("create trail response: %s",resp)

return nil
}

响应

"Error while creating trail InsufficientS3BucketPolicyException: Incorrect S3 bucket policy is detected for bucket: s3-bucket-123\n\tstatus code: 400, request id: 203d63d6-51ea-11e6-bb2c-b5d25b86e418"

任何人都可以告诉我我做错了什么。在创建Trail时需要指定的S3策略

非常感谢任何帮助/建议

Answer 1

您的Cloud Trail应该具有针对S3存储桶的此策略。按照本指南，步骤中有不同的选项。

    ]
}

Answer 2

确保添加接受的答案中提到的策略后，存储桶的name，prefix和accountID与此处指定的值是否匹配：

"Resource": "arn:aws:s3:::myBucketName/<prefix>/AWSLogs/myAccountID/*"

还要确保存在"*"后缀。

错误的配置将导致相同的错误。
