powershell - Azure Powershell如何通过Runbook获取VM的运行服务？

Question

我正在尝试编写一个 Azure Powershell Runbook 来启动 VM，然后检查 VM 上的 Windows 服务是否正在运行并启动它。

我可以启动虚拟机，但枚举服务不起作用。我是 Azure Runbooks 的新手，所以我可能做错了什么。我将下面的代码限制为仅 Get-Service 位，而不是 VM 启动。

# Returns strings with status messages
[OutputType([String])]

param (
    [Parameter(Mandatory=$false)] 
    [String]  $AzureConnectionAssetName = "AzureRunAsConnection",

    [Parameter(Mandatory=$false)] 
    [String] $ResourceGroupName = ""
)

try {
    # Connect to Azure using service principal auth
    $ServicePrincipalConnection = Get-AutomationConnection -Name $AzureConnectionAssetName         

    Write-Output "Logging in to Azure..."

    $Null = Add-AzureRmAccount `
        -ServicePrincipal `
        -TenantId $ServicePrincipalConnection.TenantId `
        -ApplicationId $ServicePrincipalConnection.ApplicationId `
        -CertificateThumbprint $ServicePrincipalConnection.CertificateThumbprint 
}
catch {
    if(!$ServicePrincipalConnection) {
        throw "Connection $AzureConnectionAssetName not found."
    }
    else {
        throw $_.Exception
    }
}

# If there is a specific resource group, then get all VMs in the resource group,
# otherwise get all VMs in the subscription.
if ($ResourceGroupName) { 
    $VMs = Get-AzureRmVM -ResourceGroupName $ResourceGroupName
}
else { 
    $VMs = Get-AzureRmVM
}

# Try and enumerate the VM's services 
foreach ($VM in $VMs) {
        Write-Output "Listing all services..."
        Write-Output ("VM: {0}" -f $VM.Name)
        $VM | Get-Service | Format-Table -AutoSize

        Write-Output "Listing alternative method..."
        Get-Service -ComputerName $VM.Name | Format-Table -AutoSize
        Write-Output "Finished listing..."
}

输出是这样的:

Logging in to Azure...

Listing all services...

VM: demo-0

Listing alternative method...

Finished listing...

嗯，首先，启动VM是异步的，所以你需要等待VM实际启动，而Get-Service无论如何也不起作用，因为无法从一个虚拟机，您需要针对该虚拟机进行身份验证，因此可以是用户 PSsessions 或调用命令，类似的东西。只需了解如何使用 powershell 远程访问服务器或如何向远程 PC 发出 powershell 命令即可。这个案例没什么不同。它与 Azure 自动化的工作原理无关。
