azure - 如何知道管道使用的是 Microsoft 托管代理还是自托管代理

Question

在运行 azure 构建管道(yml 版本)时，是否有任何编程方式(在管道本身内部)来了解当前管道是否在 ms 托管代理或自托管代理上运行？

我们有一个名为“Agent.Name”的预定义变量，它给出代理名称。

但它不断更改代理名称(托管、Azure)Agent.Name=托管，Agent.Name=Azure

有什么方法可以确定管道运行时代理的类型。

      - task: Bash@3
        displayName: Show Agent Name
        inputs:
          targetType: 'inline'
          script: |
            echo $(Agent.Name)

没有内置功能可以满足您的要求。

但是我们可以“for-each”“azure pipeline 代理池”来获取其中的所有 Microsoft 代理名称。然后比较。

trigger:
- none

# pool: 
#  name: VMAS

# 1
stages:
- stage: s1
  displayName: get the Microsoft host agents' names
  jobs:
    - job: testJob
      steps:
        - task: PowerShell@2
          name: setvar
          inputs:
            targetType: 'inline'
            script: |
              # logic here. For example you get the vars and put it into this format:
              $PAT = "<Your Personal Access Token>"
              $org_name = "<Your Organization Name>"
              $pool_id = <The microsoft hosted agent pool id>    
              $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
              $headers.Add("Authorization", "Basic "+$PAT)

              $url = "https://dev.azure.com/"+$org_name+"/_apis/distributedtask/pools/"+$pool_id+"/agents?api-version=6.0"

              $response = Invoke-RestMethod $url -Method 'GET' -Headers $headers
              $response | ConvertTo-Json


              $str = "";

              foreach ($item in $response.value) {
                  $str += $item.name
                $str += ","
              }

              Write-Host $str

              Write-Host "##vso[task.setvariable variable=outputvars;isOutput=true]$str"


# 2
- stage: s2
  displayName: check whether current agent name is one of the above
  dependsOn: s1  
  variables:
   vars: $[ stageDependencies.s1.testJob.outputs['setvar.outputvars'] ]
  jobs:
    - job:
      steps:  
      - task: PowerShell@2
        inputs:
          targetType: 'inline'
          script: |
            $varsArr = "$(vars)".Split(',')
            $microsofthostagent = 0
            foreach ($var in $varsArr)
            {
                if ($var -eq "$(Agent.Name)")
                {
                    $microsofthostagent = 1
                }
                else
                {
                }

            }
            if( $microsofthostagent -eq 1){
              Write-Host "This pipeline is based on Microsoft Host Agent."
            }else{
              Write-Host "This pipeline is based on Self Host Agent."
            }

默认情况下，自主机代理不会与 Microsoft 主机代理同名。

您只需注意不要将自主机代理命名为与 Microsoft 代理池中的代理相同的名称(例如“托管代理”、“Azure Pipelines”)

在我这边，它有效:

Microsoft 托管代理

自托管代理
