问题描述
我需要从给定的 IpPublicPrefix 更新/设置 VMScaleset 实例的公共 IP 地址（让客户将这些 IP 列入白名单）。 我尝试使用两个实例（带有虚拟网络、子网、网络接口）和 PublicIpPrefix 创建 VMScaleset，但 Azure 文档中建议的代码根本不起作用。 https://docs.microsoft.com/en-us/powershell/module/azurerm.network/set-azurermnetworkinterface?view=azurermps-6.13.0
第一个问题：下面的代码没有返回我上面创建的网络接口。这是 Azure API 中的错误吗？
Get-AzureRmNetworkInterface -ResourceGroupName "ResourceGroup1" -Name "NetworkInterface1"
它只返回为 VM 创建的网络接口列表（不是从 VMSS 创建的），不包括在 VMSS 创建期间创建的网络接口。
第二个问题：根据这里和那里的一些评论，VMSS 的 NetworkInterface 不会显示在 Azure 门户（搜索网络接口）或 AzureRM API 中，那么我们如何知道和更新 VMSS 或其实例的 NIC？
>我一直在使用 AzureRm 模块 6.13.1
解决方法
对于第一个问题，规模集实例的公网IP不是Azure门户中单独的资源，我们无法使用Get-AzureRmNetworkInterface获取网络接口信息。
对于第二个问题，您可以通过 ARM 模板为每个虚拟机创建一个具有公共 IP 的规模集。您可以将 publicIpAddressConfiguration JSON 属性添加到规模集 ipConfigurations 部分。
请注意，IpPublicPrefix 需要标准 SKU 负载平衡器和公共 IP 地址。这是一个工作示例。

此外，您可以使用 the REST API 获取虚拟机规模集中实例的指定公共 IP 地址。
GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{virtualMachineScaleSetName}/virtualMachines/{virtualmachineIndex}/networkInterfaces/{networkInterfaceName}/ipconfigurations/{ipConfigurationName}/publicipaddresses/{publicIpAddressName}?api-version=2018-10-01
