我正在尝试创建一个 Azure DEvOps 管道，使用 terraform 部署虚拟机，然后使用 WinRm 连接到该虚拟机以执行脚本，但我找不到将从 output.tf 捕获的公共 IP 传递到要在连接上使用的管道的方法。希望有人能给出一些建议来解决这个问题。

请参阅我的 .yml 文件

              Remove-PSSession -Session $session

这是我得到的错误

要在中使用变量next stage，请在阶段中添加task namepowershell 任务。tfdeploy

        - task: PowerShell@2
          displayName: 'Capture public IP and push to pipeline variable'
          name: getip             # <-- add task name
          inputs:
            targetType: 'inline'
            script: |
              $tfOutput = terraform output -json | ConvertFrom-Json
              $publicIp = $tfOutput.public_ip.value
              Write-Host "##vso[task.setvariable variable=publicIp;isOutput=true]$publicIp"
              Write-Host "Captured Public IP: $publicIp"   # < -- make sure ip value output is correct

在下一阶段，将任务名称包含在变量表达式中：

      variables:
        public_ip: $[ stageDependencies.tfdeploy.apply.outputs['getip.publicIp'] ]

有关详细信息，请参阅文档

在 powershell 任务中，请确保代理 ip$publicIp正确输出，因为该值将被设置为下一阶段的输出变量值。
