AWS CodePipeline：在CodeBuild中获取CloudFormation输出 [英] AWS CodePipeline: Get CloudFormation outputs in CodeBuild

问题描述

我正在使用AWS CodePipeline（Cloudformation和CodeBuild）学习一些DevOps技术。

I'm learning some DevOps techniques using AWS CodePipeline (Cloudformation and CodeBuild).

我的（简化的）管道是：

My (simplified) pipeline is this:

1. 推送到github存储库触发器管道


2. CloudFormation构建/更新后端基础结构


3. CodeBuild可以一些其他工作

目前，CloudFormation输出以下内容：

At the moment, CloudFormation outputs the following:

Outputs:
  RestApiId:
    Value: !Ref ApiGateway
    Description: 'API Id'

问题：如何在CloudBuild中获取ApiGateway ID？

Question: How can I get the ApiGateway ID in CloudBuild?

推荐答案

根据：
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/continuous-delivery-codepipeline-parameter-override-functions.html

您可以这样指定CodePipeline步骤（来自文档）：

You can specify CodePipeline step like this (from documentation):

- Name: CreateTestStackA
  Actions:
    - Name: CloudFormationCreate
      ActionTypeId:
        Category: Deploy
        Owner: AWS
        Provider: CloudFormation
        Version: '1'
      Configuration:
        ActionMode: CREATE_UPDATE
        Capabilities: CAPABILITY_IAM
        OutputFileName: TestOutput.json
        RoleArn: !GetAtt [CFNRole, Arn]
        StackName: StackA
        TemplateConfiguration: TemplateSource::test-configuration.json
        TemplatePath: TemplateSource::teststackA.yaml
      InputArtifacts:
        - Name: TemplateSourceA
      OutputArtifacts:
        - Name: StackAOutput
      RunOrder: '1'

配置，您需要添加 OutputFileName 参数并指定输出工件n阿美然后，您可以将该工件用作CodeBuild的输入。在输出文件（TestOutput.json）中，您将有一个字典，其中的键是输出名称，值是输出值。

So in Configuration you need to add OutputFileName parameter and specify output artifact name. Then you can use that artifact as an input to CodeBuild. In output file (TestOutput.json) you will have a dictionary where key is output name and value is output value.
