matrix - Azure Pipelines 数据驱动矩阵

Question

在 GitHub Actions 中，我可以像这样编写一个矩阵作业:

jobs:
  test:
    name: Test-${{matrix.template}}-${{matrix.os}}
    runs-on: ${{matrix.os}}
    strategy:
      matrix:
        os: [ubuntu-latest, windows-latest, macOS-latest]
        template: ['API', 'GraphQL', 'Orleans', 'NuGet']
    steps:
      #...

这将运行 os 和 template 的所有组合。在 Azure Pipelines 中，您必须像这样手动指定每个组合:

stages:
- stage: Test
  jobs:
  - job: Test
    strategy:
      matrix:
        Linux:
          os: ubuntu-latest
          template: API
        Mac:
          os: macos-latest
          template: API
        Windows:
          os: windows-latest
          template: API
        # ...continued
    pool:
      vmImage: $(os)
    timeoutInMinutes: 20
    steps:
      #...

是否可以创建类似于 GitHub Actions 的数据驱动矩阵策略？

Answer 1

Is it possible to create a data driven matrix strategy similar to GitHub Actions?

答案是肯定的。这是一个已在 github 上报告的已知问题:

Add cross-product matrix strategy

此外，在 official documentation 中有提到此问题的解决方法:

Note

The matrix syntax doesn't support automatic job scaling but you canimplement similar functionality using the each keyword. For anexample, see nedrebo/parameterized-azure-jobs.

jobs:
- template: azure-pipelines-linux.yml
  parameters:
    images: [ 'archlinux/base', 'ubuntu:16.04', 'ubuntu:18.04', 'fedora:31' ]
    pythonVersions: [ '3.5', '3.6', '3.7' ]
    swVersions: [ '1.0.0', '1.1.0', '1.2.0', '1.3.0' ]
- template: azure-pipelines-windows.yml
  parameters:
    images: [ 'vs2017-win2016', 'windows-2019' ]
    pythonVersions: [ '3.5', '3.6', '3.7' ]
    swVersions: [ '1.0.0', '1.1.0', '1.2.0', '1.3.0' ]

azure-pipelines-windows.yml:

jobs:
  - ${{ each image in parameters.images }}:
    - ${{ each pythonVersion in parameters.pythonVersions }}:
      - ${{ each swVersion in parameters.swVersions }}:
        - job:
          displayName: ${{ format('OS:{0} PY:{1} SW:{2}', image, pythonVersion, swVersion) }}
          pool:
            vmImage: ${{ image }}
          steps:
            - script: echo OS version &&
                      wmic os get version &&
                      echo Lets test SW ${{ swVersion }} on Python ${{ pythonVersion }}
