您如何将环境变量添加到 CodeBuild buildspec.yml？

Question

您如何将环境变量添加到 CodeBuild buildspec.yml？

hob*_*777 5 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，以自动部署托管在 S3 存储桶中的静态网站。为了在信用到期时给予信用，我主要遵循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 Hugo 版本添加环境变量后，我想用它来创建静态站点文件，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：模板的资源块中存在未解决的资源依赖关系 [HUGO_VERSION]。”

为什么它不接受我在 environment_variables 下定义的 HUGO_VERSION 环境变量？这是格式的 0.1 版，因此与当前的 0.2 版略有不同，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

那件事真的让我困惑的是，如果我用$ {} HUGO_VERSION删除线，模板被接受就好了-然后建立节目HUGO_VERSION = 0.49（因为printenv命令的）后，CloudWatch的日志的检查！是什么赋予了？

最初，模板看起来像这样。

我相信会发生以下情况：CloudFormation 尝试解析${HUGO_VERSION}为ParameterCloudformation 模板，因为它在“！Sub”函数中。

来自关于 Sub 函数的 AWS 文档

要按字面写出美元符号和花括号 (${})，请在左花括号后添加感叹号 (!)，例如 ${!Literal}。AWS CloudFormation 将此文本解析为 ${Literal}。

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference-sub.html#w2ab1c21c28c59b7

因此，您的构建规范阶段应类似于：

      phases:
        install:
          commands:
            - printenv
            - echo "Install step..."
            - curl -Ls https://github.com/gohugoio/hugo/releases/download/v${!HUGO_VERSION}/hugo_${!HUGO_VERSION}_Linux-64bit.tar.gz -o /tmp/hugo.tar.gz
            - tar xf /tmp/hugo.tar.gz -C /tmp
            - mv /tmp/hugo_${!HUGO_VERSION}_linux_amd64/hugo_${!HUGO_VERSION}_linux_amd64 /usr/bin/hugo
            - rm -rf /tmp/hugo*

请检查您的 CloudFormation 模板中的Environment属性AWS::CodeBuild::Project。特别是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

现在，您可以HUGO_VERSION在buildspec.yml文件中将其作为环境变量引用，例如

pre_build:    
  commands:
    - echo HUGO_VERSION $HUGO_VERSION
