amazon-web-services - 如何将环境变量添加到 CodeBuild buildspec.yml？

标签 amazon-web-services aws-cloudformation hugo aws-codepipeline aws-codebuild

我正在尝试使用 CloudFormation 模板来定义 CodeBuild 和 CodePipeline，以自动部署 S3 存储桶中托管的静态网站。为了给予应得的信任，我很大程度上遵循 https://dzone.com/articles/continuous-delivery-to-s3-via-codepipeline-and-cod 中的模板。 。

我无法解决的问题是，在我为我想用来创建静态站点文件的 Hugo 版本添加环境变量后，我从 AWS 控制台收到一条错误消息:“模板验证错误:模板格式错误:模板的资源 block 中未解析的资源依赖项 [HUGO_VERSION]。”

为什么它不接受我在environment_variables下定义的HUGO_VERSION环境变量？这是该格式的 0.1 版本，因此与当前的 0.2 版本略有不同，但我已阅读以下链接:https://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html#build-spec-ref-syntax

真正让我困惑的是，如果我删除带有 ${HUGO_VERSION} 的行，模板就会被很好地接受 - 然后在构建后检查 CloudWatch 日志显示(因为printenv 命令)HUGO_VERSION=0.49!给出了什么？

最初，模板看起来像这样。

最佳答案

请检查Environment CloudFormation 模板中 AWS::CodeBuild::Project 的属性。具体来说，EnvironmentVariables 允许您指定环境变量，例如

  CodeBuildDeploySite:
    Type: AWS::CodeBuild::Project
    DependsOn: CodeBuildRole
    Properties:
      Name: !Sub ${AWS::StackName}-DeploySite
      Description: Deploy site to S3
      ServiceRole: !GetAtt CodeBuildRole.Arn
      Artifacts:
        Type: CODEPIPELINE
      Environment:
        Type: !Ref BuildType
        ComputeType: !Ref BuildComputeType
        Image: !Sub ${BuildImage}
        EnvironmentVariables:
          - Name: HUGO_VERSION
            Value: '0.49'
            Type: PLAINTEXT

# More properties...

现在，您可以在 buildspec.yml 文件中引用 HUGO_VERSION 作为环境变量，例如

pre_build:    
  commands:
    - echo HUGO_VERSION $HUGO_VERSION
