如何将列表作为构建参数传递给 Azure DevOps Server 2019（本地）中的 YAML 模板？

Question

例如，考虑以下模板（例如名为 xyz.yml）：

parameters:
  projects: ['p1', 'p2', 'p3']

steps:
- ${{ each project in parameters.projects }}:
  - task: VSBuild@1
    displayName: Build ${{ project }}
    inputs:
      solution: ${{ project }}.sln
      ...

现在，假设我有以下 azure-pipelines.yml 文件：

...
steps:
  ...
  - template: xyz.yml
    parameters:
      projects: ???
...

如何从构建变量中提供projects 模板参数？假设在构建时我只想请求构建 p1 和 p3。我该怎么做？

Answer 1

您可以尝试使用 stepList 类型参数并将相同的参数值传递给模板。

例如：

main.yaml:

parameters:
  - name: mySteplist
    type: stepList
    default:
    - task: CmdLine@2
      inputs:
        script: |
          echo Write your commands here
          
          echo Hello world1
    - task: CmdLine@2
      inputs:
        script: |
          echo Write your commands here
          
          echo Hello world2

trigger:
  - none

steps:
  - template: stepstem.yml
    parameters: 
      buildSteps:
      - ${{ parameters.mySteplist }}
    
  # - template: stepstem.yml
  #   parameters:
  #     buildSteps:  
  #     - bash: echo Test #Passes
  #       displayName: succeed
  #     - bash: echo "Test"
  #       displayName: succeed
  # - ${{ parameters.mySteplist }}
  - task: CmdLine@2
    inputs:
      script: |
        echo Write your commands here
        
        echo Hello world3

stepstem.yaml：

parameters:
- name: buildSteps # the name of the parameter is buildSteps
  type: stepList # data type is StepList
  default: []

steps:
  - ${{ parameters.buildSteps }}
  - task: CmdLine@2
    inputs:
      script: |
        echo Write your commands here
        
        echo Hello world tem
  - script: echo "hello"

因此，您可以使用 VSBuild@1 任务作为默认参数值，并且可以在队列构建时更改它。

检查以下示例：

#xyz.yml

parameters:
  projects: []

steps:
- ${{ each project in parameters.projects }}:
  - task: VSBuild@1
    displayName: Build ${{ project }}
    inputs:
      solution: ${{ project }}.sln
      ...
      ...

#azure-pipelines.yml

 steps:
 - template: xyz.yml
   parameters:
     projects: ["p1", "p3"]
