从 .ps1 文件中读取变量并使用 Git Repo 在 Pipeline 中运行 .ps1 脚本

问题描述 投票：0回答：2

我正在使用 Azure DevOps 存储库，并且正在开发管道。我希望它从 config.ps1 文件中读取变量并用它设置一个环境变量。之后我想运行一个 powershell 脚本。它给出了路径和读取参数的错误。

我不想阅读这个 config.yml 并安装这个模块，我想要一些更简单的东西，比如 config.ps1 只是说明变量。然后在此处检索该变量并将其分配给环境变量。

trigger:
- main
- test

pool:
  vmImage: 'windows-latest'

variables:
  MES_SERVER_USERNAME: '$(SERVER_USERNAME)'
  MES_SERVER_PASSWORD: '$(SERVER_PASSWORD)'
  TEST_SERVER_IP: '$(TEST_IP)'
  PROD_SERVER_IP: '$(PROD_IP)'

stages:
  - stage: DeployToServer
    jobs:
      - deployment: DeployToTest
        displayName: 'Deploy to Test Deployment Group'
        condition: eq(variables['Build.SourceBranch'], 'refs/heads/test')

我建议不要通过双步方法使过程复杂化。相反，您可以直接在管道环境变量中设置值。鉴于您使用 YAML 来获取此值，因此不需要动态检索它。

但是，如果您确实更喜欢采用这种替代方法，则可以创建一个 Environment.psm1 文件并在其中定义全局变量。具体方法如下：

  1. 创建Environment.psm1文件：

    $global:TGRP_FOLDER_PATH = 'path'

  2. 在脚本中导入模块：

    Import-Module -Name Environment -Force

通过执行这些步骤，您将设置一个可以在脚本中轻松导入和使用的全局变量。

总而言之，虽然直接在管道中设置环境变量是更直接、更有效的方法，但如果您的用例需要，替代方法可以提供灵活性。

我希望它从 config.ps1 文件中读取变量并用它设置一个环境变量。

我想从文件中读取静态值

而不是使用以下代码片段：

$config = Import-Yaml -Path "../config.yml"
$env:TGRP_FOLDER_PATH = $config.variables.TGRP_FOLDER_PATH

尝试使用管道中定义的变量或变量模板？

例如定义如下的变量：

variables:
  - name: TGRP_FOLDER_PATH
    value: /my/folder/

可以使用宏语法作为环境变量进行访问

$(TGRP_FOLDER_PATH)
。

示例

为每个环境使用变量模板：

# /pipelines/variables/main-variables.yaml

variables:
  - name: TGRP_FOLDER_PATH
    value: /my/main/folder/

# /pipelines/my-pipeline.yaml

variables:
  - name: TGRP_FOLDER_PATH
    value: /my/prod/folder/

在不同的作业中使用每个模板：

stages:
  - stage: DeployToServer
    jobs:
      - deployment: DeployToTest
        displayName: 'Deploy to Test Deployment Group'
        condition: eq(variables['Build.SourceBranch'], 'refs/heads/test')
        environment: 'TestEnvironment'
        variables:
          - template: variables/test-variables.yaml # <---------- reference test variables template here
        strategy:
          runOnce:
            deploy:
              steps:
                - checkout: none
                - powershell: |

                    echo "$(TGRP_FOLDER_PATH)" # Output: /my/test/folder/

                    # rest of the script here
                  displayName: 'Get Changed Files and Run PowerShell script'

      - deployment: DeployToMain
        displayName: 'Deploy to Main Deployment Group'
        condition: eq(variables['Build.SourceBranch'], 'refs/heads/main')
        environment: 'MainEnvironment'
        variables:
          - template: variables/main-variables.yaml # <---------- reference test variables template here
        strategy:
          runOnce:
            deploy:
              steps:
                - checkout: none
                - powershell: |

                    echo "$(TGRP_FOLDER_PATH)" # Output: /my/main/folder/

                    # rest of the script here
                  displayName: 'Get Changed Files and Run PowerShell script'
