如何使用AWS SAM部署到多个方面(开发、发布、生产)？

Question

我有一个AWS SAM模板，其中我有一个带有API的Lambda，并且我希望能够将这个lambda部署到不同的环境中，比如开发、发布和生产，作为任何其他项目，这样在到达最终的最终用户之前，一切都可以很好地进行测试。

到目前为止，我已经尝试在我的模板中创建一个参数，用于在部署时更改环境，第一次使用name-develop部署lambda，但是当我试图发布它时，只是用name-release代替了name-develop，而不是让这两个lambda共存。

这是我的模板：

​

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
  ocr-app

  Sample SAM Template for ocr-app
  
# More info about Globals: https://github.com/awslabs/serverless-application-model/blob/master/docs/globals.rst
Globals:
  Function:
    Timeout: 15

Parameters:
  Env:
    Type: String
    AllowedValues:
      - develop
      - release
      - product
    # Default: develop
    Description: Environment in which the application will be deployed. Allowed values [develop, release, product]


Resources:
  OCRFunction:
    Type: AWS::Serverless::Function # More info about Function Resource: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#awsserverlessfunction
    Properties:
      Environment:
          Variables:
            ENV: !Ref Env
      CodeUri: ocr/
      Handler: app.lambdaHandler
      FunctionName: !Sub OCRFunction_${Env}
      Runtime: nodejs14.x
      Policies: 
        - S3ReadPolicy: # Managed Policy
            BucketName: "*"
        - AWSLambdaExecute # Managed Policy
      Architectures:
        - x86_64
      Events:
        OCR:
          Type: Api # More info about API Event Source: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#api
          Properties:
            Path: /ocr
            Method: get

Outputs:
  # ServerlessRestApi is an implicit API created out of Events key under Serverless::Function
  # Find out more about other implicit resources you can reference within SAM
  # https://github.com/awslabs/serverless-application-model/blob/master/docs/internals/generated_resources.rst#api
  OCRApi:
    Description: "API Gateway endpoint URL for Prod stage for Hello World function"
    Value: !Sub "https://${ServerlessRestApi}.execute-api.${AWS::Region}.amazonaws.com/Prod/hello/"
  OCRFunction:
    Description: "Hello World Lambda Function ARN"
    Value: !GetAtt OCRFunction.Arn
  OCRFunctionIamRole:
    Description: "Implicit IAM Role created for Hello World function"
    Value: !GetAtt OCRFunctionRole.Arn

如何部署到多个环境？

Answer 1

到目前为止，我发现的一种方法是创建另一个堆栈--每个环境都创建一个堆栈。我不确定这是否是唯一/最好的方法，所以我愿意听取其他意见。
