AWS 创建存储桶失败，问题是什么？

Question

出现此错误：

S3 err creating bucket: operation error S3: CreateBucket, https response error StatusCode: 0, RequestID: , HostID: , request send failed, Put "https://s3..amazonaws.com/astromail-test3.com": dial tcp: lookup s3..amazonaws.com: no such host. With bucket name: astromail-test3.com

当我将凭据切换为默认值时，它可以正常工作并创建存储桶。但是，当我使用自定义 IAM 时，它不起作用，但该错误不是权限错误。到底是怎么回事？我相信我已经设置了正确的权限，如果这是问题所在，通常 sdks 会输出一个权限被拒绝的权限，并且您可以更新所需的权限。上面的输出只是失败了。

我找到了解决方案，关键部分是将这个 config.WithRegion("us-east-1") 添加到 sdkConfig 变量初始化中。这是完整的代码，我做了一些更多的更改，例如等待创建存储桶。

func CreateEmailBucket(domain string) error {
    bucketName := makeAWSS3BucketNameCompliant(fmt.Sprintf("AstroMail-%s", domain))

    sdkConfig, err := config.LoadDefaultConfig(context.TODO(), config.WithSharedConfigProfile("AstroMailApp"), s)

    fmt.Println(sdkConfig, err, bucketName)

    s3Client := s3.NewFromConfig(sdkConfig)

    createBucketParams := &s3.CreateBucketInput{
        Bucket: aws.String(bucketName),
    }

    _, err = s3Client.CreateBucket(context.TODO(), createBucketParams)

    if err != nil {
        panic(fmt.Errorf("failed to create bucket: %v", err))
    }

    // Wait for S3 Bucket to Exist
    fmt.Println("wait for s3 bucket to exist")
    waiter := s3.NewBucketExistsWaiter(s3Client)
    err = waiter.Wait(context.TODO(), &s3.HeadBucketInput{
        Bucket: aws.String(bucketName),
    }, 120*time.Second)

    if err != nil {
        panic(fmt.Sprintf("bucket failed to materialize: %v", err))
    }

    storage.SaveKey("bucketName", bucketName)
    return nil
}

等待存储桶创建只是等待设定的时间，我认为这并不明智，因为它在大多数情况下创建得更快。我将使其循环并检查多次。谢谢评论的人。
