“GetObject 时发生错误。S3 错误代码：PermanentRedirect。S3 错误消息：存储桶位于此区域：us-east-1

Question

我尝试关注这个研讨会https://gitflow-codetools.workshop.aws/en/，一切都很好，但是当我尝试使用 cloudformation 创建 lambda 时出现错误：

Resource handler returned message: "Error occurred while GetObject. S3 Error Code: 
  PermanentRedirect. S3 Error Message: The bucket is in this region: 
  us-east-1. Please use this region to retry the request (Service: Lambda, 
  Status Code: 400, Request ID: xxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxxx, 
  Extended Request ID: null)" (RequestToken: xxxxxx-xxxxx-xxxx-xxxx-xxxxxxxxxx, HandlerErrorCode: InvalidRequest)

我在本次研讨会中使用 eu-west-1，但我不明白为什么 cloudformation 在 us-east-1 中创建存储桶。

当我在 us-east-1 中部署 cloudformation 时，我没有收到此错误。

知道如何避免这个错误吗？

模板如下所示：

Answer 1

首先，Lambda 和 S3 需要在同一个区域。

其次，看起来您不是存储桶所有者（您还没有通过查看模板自己创建存储桶）。

这意味着，您用于从中检索 Lambda 源代码的存储桶是（我想来自研讨会），他们决定在 us-east-1 区域创建该存储桶。强制您在区域 us-east-1 中部署您的堆栈（如果您想关注研讨会）。

但如果您真的想将此堆栈部署到 eu-west-1 怎么办？

这意味着您需要在区域 eu-west-1 中创建一个存储桶，并将车间存储桶中的对象复制到您新创建的存储桶中，并更新您的 CloudFormation 模板以指向和检索新创建的 Lambda 源代码存储桶（请注意，您可能需要以不同的方式命名存储桶，因为存储桶名称是全局共享的）。

我希望这有点清楚。
