Question

我需要使用Azure Powershell Runbook在具有特定用户帐户的远程VM上运行启动过程

function Install-Postgres {

$username = "aact-import-vm1\aact-importer"

$password = "ChangeMe!"


    $cred = New-Object System.Management.Automation.PSCredential -ArgumentList `
        @($username,(ConvertTo-SecureString -String $password -AsPlainText -Force))

    write-output $cred
    # run pg installer
    Start-Process "C:\Program Files\WindowsPowerShell\Modules\Install-Postgres\postgresql.exe" -ArgumentList `
     "--mode unattended", "--unattendedmodeui none",`
     "--prefix `"C:\Program Files\PostgreSQL\10`"", "--datadir `"C:\Program Files\PostgreSQL\10\data`"", 
     "--superpassword `"ChangeMe!`"",`
     "--servicename `"postgres`"", "--serviceaccount `"postgres`"", "--servicepassword `"ChangeMe!`""`
     -Wait -Credential $cred;
}

$script = Get-Content Function:\Install-Postgres
Out-File -FilePath Install.ps1 -InputObject $script

#Note that the -ScriptPath should not point to the remote path(in remote vm), it should point to the local path where you execute the command Invoke-AzureRmVMRunCommand
$output = Invoke-AzVMRunCommand -ResourceGroupName $resourceGroupName -Name $vmName -CommandId 'RunPowerShellScript' -ScriptPath Install.ps1
write-output $output.Value

#after execution, you can remove the file
Remove-Item -Path Install.ps1

上面的脚本产生以下错误：

启动过程：由于以下错误而无法运行此命令：访问被拒绝。

如果我在没有特定凭据的情况下运行上述脚本，则postgres安装程序会在日志中产生此错误：

Executing icacls "C:\Windows\Temp/postgresql_installer_1ef9b3f2c6" /T /Q /grant "WORKGROUP\aact-import-vm1$:(OI)(CI)F"
Script exit code: 1332

Script output:
 Successfully processed 0 files; Failed processing 1 files

Script stderr:
 WORKGROUP\aact-import-vm1**$**: No mapping between account names and security IDs was done.

请注意，符号 $ 代替了用户名。

但是，如果我在VM上运行它，则可以正常运行并在日志中生成以下行：

Executing icacls "C:\Users\aact-importer\AppData\Local\Temp\2/postgresql_installer_2662c862ff" /T /Q /grant "aact-import-vm1\aact-importer:(OI)(CI)F"
Script exit code: 0

据我所知，如果我不带凭据就远程运行Runbook脚本，则它将在NTAUTHORITY \ SYSTEM下运行，这就是为什么postgres安装程序日志中使用符号$代替用户名的原因。如果我在本地运行它，它将使用适当的用户，并且一切正常。

问题是：如何指定用户帐户在远程VM上运行启动进程？

对于那些感兴趣的人：

在获得MS支持的调查后，他们确认Runbook（非混合）始终在NTAUTHORITY \ SYSTEM下运行

使用Azure Runbook在远程VM上特定用户下调用Invoke-AzVMRunCommand和Start-Process
