如何使用 CodeCommit 和 Code Pipeline 部署到多个环境

How to deploy to multiple environments using CodeCommit and Code Pipeline

我使用 CodeCommit 作为我的代码存储库,因为代码提交使您能够将代码部署到另一个环境中的跨账户。我在 template.yaml 使用 AWS SAM 的 QA 环境中设置了一个 lambda 函数。

我应该在代码管道的什么地方定义环境变量,以便 lambda 函数可以部署在另一个帐户的 Prod 环境中?

我将如何定义变量,以便在 prod 环境中合并暂存 lambda 函数时它采用 prod 环境变量?

因为在合并代码时在 prod 环境中定义暂存环境变量没有任何意义。

是否会在代码构建中定义环境变量?

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: CD Demo Lambda
Resources:
  CDDemoLambda:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: lambda_function.lambda_handler
      Runtime: python3.6
      CodeUri: ./LambdaCode
      FunctionName: ApigatewayLambda
      AutoPublishAlias: ApiLambda
      Description: 'Lambda function validation'
      MemorySize: 128
      Timeout: 30
      Events:
        ApiEvent:
          Type: Api
          Properties:
            Path: /getazs
            Method: get
      Environment:
        Variables:
          CONFIG_BUCKET: staging-bucket-name
          CONFIG_KEY: source-data-key-path

您可以使用 cloudformation 中的参数和条件功能来执行此操作,例如,您将添加如下参数部分:

Parameters:
  Stage:
    Type: String
    Default: staging
    Description: Parameter for getting the deployment stage

然后是一个带有映射的映射部分,用于保存所有阶段的环境变量

Mappings:
  StagesMap:
    staging:
      CONFIG_BUCKET: staging-bucket-name
      CONFIG_KEY: source-data-key-path
    prod:
      CONFIG_BUCKET: prod-bucket-name
      CONFIG_KEY: source-data-key-path

那么您的函数可以根据您所处的环境使用变量:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: CD Demo Lambda
Resources:
  CDDemoLambda:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: lambda_function.lambda_handler
      Runtime: python3.6
      CodeUri: ./LambdaCode
      FunctionName: ApigatewayLambda
      AutoPublishAlias: ApiLambda
      Description: 'Lambda function validation'
      MemorySize: 128
      Timeout: 30
      Events:
        ApiEvent:
          Type: Api
          Properties:
            Path: /getazs
            Method: get
      Environment:
        Variables:
          CONFIG_BUCKET: !FindInMap
            - StagesMap
            - Ref: Stage
            - CONFIG_BUCKET
          CONFIG_KEY: !FindInMap
            - StagesMap
            - Ref: Stage
            - CONFIG_KEY

现在,当您调用 sam 部署命令时,您需要定义要部署到哪个阶段。 例如:

sam deploy --parameter-overrides Stage=prod

您完整的 cloudformation 模板应如下所示:

      CONFIG_KEY: source-data-key-path
    prod:
      CONFIG_BUCKET: prod-bucket-name
      CONFIG_KEY: source-data-key-path
