azure - Azure Yaml 管道中的覆盖变量不起作用

Question

我的目的是使用默认变量运行管道。变量createRelease 应该指示除了“TestApplication”之外还应该运行哪个作业。

伪代码:

RunJob('TestApplication')

if(!createRelease) 
    RunJob('BuildForDev')

if(createRelease)
    RunJob('BuildForUatRelease')

不知何故，它不会覆盖 createRelease 的值。有人知道为什么不吗？

我的管道 yaml 如下所示:

trigger:
- main
- feature/*

pool:
  vmImage: ubuntu-latest

variables:  
  - name: createRelease
    value: false

stages:
  - stage: CI_Build
    displayName: Build and Test App
    jobs:
      - job: TestApplication
        displayName: Building and testing
        condition: always()
        steps:
          - task: Bash@3
            displayName: Maven Test Application
            inputs:
              targetType: 'inline'
              script: |
                echo 'mvn test'
      - job: BuildForDev
        displayName: Build Application for Develop
        dependsOn: TestApplication
        condition: |
          and(
            succeeded('TestApplication'),
            eq(variables['Build.SourceBranchName'], 'main'),
            eq(variables.createRelease, 'false')
          )
        steps:
          - task: Bash@3
            displayName: Maven test Application
            inputs:
              targetType: 'inline'
              script: |
                echo mvn test
      - job: BuildForUatRelease
        displayName: Release Application
        dependsOn: TestApplication
        condition: |
          and(
            succeeded('TestApplication'),
            eq(variables['Build.SourceBranchName'], 'main'),
            eq(variables.createRelease, 'true')
          )
        steps:
          - task: Bash@3
            displayName: Set Git Credentials
            inputs:
              targetType: 'inline'
              script: |
                echo 'mvn release prepare'

Pipeline 中可以被覆盖的变量定义:

如何在运行前设置createRelease:

Answer 1

您在 YAML 中分配变量的值，该值将优先于队列时定义的变量。这样想可能会有所帮助:

• 您使用 createRelease: True 变量对管道进行排队
• Azure DevOps 为管道创建执行上下文并执行 pipeline.yml
• 您的管道定义了 createRelease: False 的值

解决方法:

1. 从 yaml 中删除 createRelease 变量

2. 编辑管道:

   

3. 点击变量:

   

4. 添加新变量并设置 createRelease 变量的默认值。将其设置为允许用户在队列时更改值:

   

5. 单击“确定”。

或者，您可能需要考虑创建参数而不是变量:

trigger:

parameters:
- name: createRelease
  displayName: 'Create a Release'
  type: boolean
  default: false

stages:
- stage: ...
  jobs:
  - job: ...
    steps:
    - script: 'hello'
      condition: ${{ eq( parameters.createRelease, 'true') }}
