Powershell 脚本无法将 Register-ScheduledJob 作为 Azure 资源管理器 CustomScriptExtension 执行

Question

我有一个用于 Azure 虚拟机规模的部署模板，具有以下扩展配置文件:

"extensionProfile": {
    "extensions": [
      {
        "name": "customScript",
        "location": "[resourceGroup().location]",
        "properties": {
          "publisher": "Microsoft.Compute",
          "type": "CustomScriptExtension",
          "settings": {
            "fileUris": [
              "[concat(parameters('customInstallScriptLocation'), parameters('customInstallScriptFileName'))]"
            ]
          },
          "typeHandlerVersion": "1.8",
          "autoUpgradeMinorVersion": true,
          "protectedSettings": {
            "commandToExecute": "[concat('powershell -ExecutionPolicy Unrestricted -File \"', parameters('customInstallScriptFileName'), '\" -adminUsername ', parameters('adminUsername'), ' -adminPassword ', parameters('adminPassword'))]"
          }
        }
      }
    ]
  }

部署 vmss 时，执行自定义脚本，Invoke-WebRequest 和 Start-Process 等命令可以正常工作。但 Register-ScheduledJob 不起作用。当我连接到远程桌面并手动运行此安装脚本时，一切正常。

这是不手动运行时失败的代码:

$trigger = New-JobTrigger -AtStartup -RandomDelay 00:00:45
Register-ScheduledJob -Trigger $trigger -FilePath $installDir\natPuncherStartupScript.ps1 -Name NPSSOnStartup >> $log
logAndClearErrors $true

错误是:

Register-ScheduledJob : An error occurred while registering scheduled jobdefinition NPSSOnInstall to the Windows Task Scheduler.  The Task Scheduler error is: (32,4):UserId:.

我也尝试过:

$trigger = New-JobTrigger -AtStartup -RandomDelay 00:00:45
Register-ScheduledJob -Credential $credential -Trigger $trigger -FilePath $installDir\natPuncherStartupScript.ps1 -Name NPSSOnStartup >> $log
logAndClearErrors $true

但现在错误显示用户名/密码无效。此外，当从远程桌面手动运行它时，效果很好。

我错过了什么？为什么我无法通过自定义脚本扩展安排作业？

如果您想让 vmextension 注册它，您需要以 LocalSystem 帐户登录。

Register-ScheduledTask -TaskName $jobname -Action $action -Trigger $trigger -RunLevel Highest -User "System" -Settings $settings
