amazon-web-services - AWS CloudTrail Create API for Go SDK 引发错误消息“InsufficientS3BucketPolicyException：检测到存储桶的 S3 存储桶策略不正确：”

Question

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

我按照以下步骤创建跟踪

Step1 - 创建 S3 存储桶，以便所有跟踪日志文件都可以放在此存储桶中。

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
}

成功响应：

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

第 2 步 - 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
}

回复

"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" 

谁能告诉我我在哪里做错了。创建 Trail 时我需要指定什么 S3 策略

非常感谢任何帮助/建议

参考： https ://docs.aws.amazon.com/sdk-for-go/api/service/cloudtrail/#CloudTrail.CreateTrail

Answer 1

确保在添加接受的答案中提到的策略后，您的存储桶的name和prefix与accountID此处指定的值匹配：

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

还要确保"*"后缀存在。

那里的错误配置会导致同样的错误。

Answer 2

您的 Cloud Trail 应该具有适用于 S3 存储桶的此政策。按照本指南，该步骤中有不同的选项。
