amazon-web-services - 如何在 SAM template.yml 中包含多个资源文件

Question

我想在不同的文件中编写我的云形成 yml 文件并分别加载它们。在无服务器框架中很容易做到这一点，但我不知道如何使用 SAM 做到这一点。
你介意帮我怎么做吗？

我提供了以下项目的副本:

我的 template.yml 文件:

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
  Sample SAM Template

# Create our resources with separate CloudFormation templates
resources:
  Resources:
    # Lambda function
    - ${file(resources/lambda-functions.yml)}

我的资源文件(lambda-functions.yml)如下:

  HelloWorldFunction:
    Type: AWS::Serverless::Function 
    Properties:
      CodeUri: hello-world/
      Handler: app.lambdaHandler
      Runtime: nodejs12.x
      Events:
        HelloWorld:
          Type: Api 
          Properties:
            Path: /helloworld
            Method: get

我的文件夹结构。

构建中的错误1(已解决):

Transform AWS::Serverless-2016-10-31 failed with: Invalid Serverless Application Specification document. Number of errors found: 1. Structure of the SAM template is invalid. 'Resources' section is required Created time

部署中的错误 2(执行变更集)

构建部分中的 Error3

错误4:
现在代码构建成功，在部署过程中出现以下错误。

Template format error: At least one Resources member must be defined.

The following resource(s) failed to create: [yourApplicationAliasName]. . Rollback requested by user.

Answer 1

您可以使用 Location属性(property) ( https://docs.aws.amazon.com/de_de/serverless-application-model/latest/developerguide/serverless-sam-template-nested-applications.html )

在你的情况下应该是这样的

模板.yml

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
  Sample SAM Template

# Create our resources with separate CloudFormation templates resources:
Resources:
  yourApplicationAliasName:
    Type: AWS::Serverless::Application
    Properties:
      # Lambda function
      Location: ./resources/lambda-functions.yml

和 lambda-functions.yml 文件

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: AWS Lambda function.
Resources:
  HelloWorldFunction:
    Type: AWS::Serverless::Function 
    Properties:
      CodeUri: hello-world/
      Handler: app.lambdaHandler
      Runtime: nodejs12.x
      Events:
        HelloWorld:
          Type: Api 
          Properties:
            Path: /helloworld
            Method: get

尝试使用 be sam 命令进行打包，如下所示:

sam package --template template.yml --output-template-file outputtemplate.yml --s3-bucket your-bucket-name

那么你需要部署它:

sam deploy --template-file outputtemplate.yml --stack-name your-bucket-name --capabilities CAPABILITY_IAM CAPABILITY_AUTO_EXPAND

** 如果有的话，不要忘记删除以前的堆栈。

谢谢!.........
