Azure 管道条件

Question

我是 azure 的新手。有人告诉我，我需要提出一个条件:“如果这是一个请求池，那么我们根据内容运行它。如果这是一个构建，那么我们运行所有内容。”正如我所看到的，每个任务在所有这些任务中都已经有一个条件:

condition: eq(dependencies.check.outputs['Check Changes.BE '], 'true')

正如你所看到的，任务的执行取决于BE\FE变量。使用该变量的任务如下所示:

- task: CheckChanges@1
              name: CheckChanges
              pool: "windows-latest" 
              inputs:
                rules: |
                  [FE]
                  **/*.json
                  **/*.ts
                  **/*.js
                  **/*.tsx
                  **/*.scss
                  **/*.html
                  **/*.css
                  
                  [BE]
                  **/*.csproj
                  **/*.cs
                  **/*.yml
                  **/*.yaml

以下是需要完成的任务:

        - job: Restore BE
          displayName: Restore BE
          dependsOn: CheckChanges
          condition: eq(dependencies.check.outputs['CheckChanges.BE'], 'true')
          steps:          
            - task: Cake@2
              displayName: Restore FE and Sitecore modules
              inputs:
                script: "$(Build.Repository.LocalPath)/src/build.cake"
                target: "Server :: Restore"
                verbosity: "Quiet"
                Version: "1.3.0"
                
        - job: Restore FE
          displayName: Restore FE
          dependsOn: CheckChanges
          condition: eq(dependencies.check.outputs['CheckChanges.FE'], 'true')
          steps:          
            - task: Cake@2
              displayName: Restore FE and Sitecore modules
              inputs:
                script: "$(Build.Repository.LocalPath)/src/build.cake"
                target: "Client :: Restore"
                verbosity: "Quiet"
                Version: "1.3.0"

       - job: Build BE
        displayName: Build BE
        dependsOn: CheckChanges
        condition: eq(dependencies.check.outputs['CheckChanges.BE'], 'true')
        steps:
          - task: Cake@2
            displayName: Generate and Build FE and Sitecore
            inputs:
              script: "$(Build.Repository.LocalPath)/src/build.cake"
              target: "Server :: Build"
              verbosity: "Quiet"
              arguments: '--BuildConfiguration "Release" --ScSiteUrl "dummy"'
              Version: "1.3.0"
              
      - job: Build FE
        displayName: Build FE
        dependsOn: CheckChanges
        condition: eq(dependencies.check.outputs['CheckChanges.FE'], 'true')
        steps:
          - task: Cake@2
            displayName: Generate and Build FE and Sitecore
            inputs:
              script: "$(Build.Repository.LocalPath)/src/build.cake"
              target: "Client :: Build"
              verbosity: "Quiet"
              arguments: '--BuildConfiguration "Release" --ScSiteUrl "dummy"'
              Version: "1.3.0"

      - job: Unit tests BE
        displayName: Unit tests BE
        dependsOn: CheckChanges
        condition: eq(dependencies.check.outputs['CheckChanges.BE'], 'true')
        steps:
          - task: Cake@2
            displayName: Run Unit tests
            inputs:
              script: "$(Build.Repository.LocalPath)/src/build.cake"
              target: "Server :: Tests"
              verbosity: "Quiet"
              Version: "1.3.0"
                
      - job: Unit tests FE
        displayName: Unit tests FE
        dependsOn: CheckChanges
        condition: eq(dependencies.check.outputs['CheckChanges.FE'], 'true')
        steps:
          - task: Cake@2
            displayName: Run Unit tests
            inputs:
              script: "$(Build.Repository.LocalPath)/src/build.cake"
              target: "Client :: Tests"
              verbosity: "Quiet"
              Version: "1.3.0"

我不明白我需要做什么。我的团队负责人只是说:“如果是 Pull 请求，那么我们根据内容运行它。如果是构建，那么我们运行所有内容。”

Answer 1

If it's a Pull Request, then we run it depending on the content. If it's a build, then we run everything.

您可以使用管道预定义变量:Build.Reason来确认管道是否是由 Pull Request 或其他方法触发的。

您可以在条件中添加预定义变量并使用表达式来链接过滤器。

例如:

向 CheckChanges 任务添加条件。

- task: CheckChanges@1
  condition: eq(variables['Build.Reason'], 'PullRequest')

向其他作业添加条件:

    - job: Restore BE
      displayName: Restore BE
      dependsOn: CheckChanges
      condition:  Or(eq(dependencies.check.outputs['CheckChanges.FE'], 'true'),ne(variables['Build.Reason'], 'PullRequest'))

      steps:          
        - task: Cake@2
          displayName: Restore FE and Sitecore modules
          inputs:
            script: "$(Build.Repository.LocalPath)/src/build.cake"
            target: "Server :: Restore"
            verbosity: "Quiet"
            Version: "1.3.0"
            

说明:

当 Pipeline 被 Pull Request 触发时，会运行 checkChanges 任务，任务会根据内容运行。

或者，如果管道不是由拉取请求触发的，则管道将运行所有任务。
