amazon-web-services - AWS cloudformation 嵌套堆栈因模板 URL 失败

Question

我是 cloudformation 的新手，但当前项目有一个模板，其中所有资源都位于一个唯一的文件中，我们尝试使用嵌套堆栈选项将多个文件分开。当我尝试部署模板时，执行失败并显示下一条消息:

$ aws s3 cp testing-substack.yml s3://gitlab-cicd

upload: ./testing-substack.yml to s3://gitlab-cicd/testing-substack.yml


$ aws cloudformation package --template-file testing-mainstack.yml --s3-bucket gitlab-cicd --output-template testing-packstack.yaml

Unable to upload artifact substack-amp.yml referenced by TemplateURL parameter of SubstackA resource.
TemplateURL parameter of SubstackA resource is invalid. It must be a S3 URL or path to CloudFormation template file. Actual: /builds/project-0/substack-amp.yml

接下来包含两个模板(lambda 函数只有一个“Hello world”:

测试-mainstack.yml

测试A

Resources:
  SubstackA:
    Type: 'AWS::CloudFormation::Stack'
    Properties:
      TemplateURL: testing-substack.yml

测试B

Resources:
  SubstackA:
    Type: 'AWS::CloudFormation::Stack'
    Properties:
      TemplateURL: s3://gitlab-cicd/testing-substack.yml

子堆栈模板:testing-substack.yml

  TestingSubLambda:
    Type: AWS::Serverless::Function
    Properties:
      Description: "Testing lambda inside substack"
      CodeUri: ./
      Handler: lambda-two.lambda_handler
      Runtime: python3.8
      FunctionName: TestingSubLambda
      # Role: arn:aws:iam::000365055762:role/lambda-essential-role
      Timeout: 480
      # Events:
      #   B2bCImportOrdersApiEvent:
      #     Type: Api
      #     Properties:
      #       Path: /b2b-channels/import-orders
      #       Method: GET
      #       RestApiId: !Ref B2bCAPIDev

如何确定将子堆栈定义到主堆栈中的正确方法？

TemplateURL 应写为 S3 中的 URL，因此 https://...。

在 this doc ，写为:

TemplateURL: https://s3.amazonaws.com/cloudformation-templates-us-east-1/S3_Bucket.template
