Azure 如何获得虚拟机&x27；使用ARM模板从虚拟机规模集中删除的私有IP？

我创建了一个带有虚拟机规模集的ARM模板，现在我陷入了ARM模板的开发中，因为我无法获得在规模集内创建的虚拟机的私有IP。使用扩展脚本更新Cassandra种子需要私有IP

如何获取在比例集中创建的虚拟机的私有IP？

您可以使用该函数获取虚拟机实例的NIC资源。实例NIC的资源id如下所示：

/subscriptions/{subscriptionId}/resourceGroups/{groupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmssName}/virtualMachines/{instanceId}/networkInterfaces/{nicName}

"variables": {
    "instanceNic-0": "[concat('/subscriptions/{subscriptionId}/resourceGroups/{groupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmssName}/virtualMachines/0/networkInterfaces/', parameters('nicName'))]" 
},
"outputs": {
    "instanceNic-0-IP": {
        "type": "string",
        "value": "[reference(variables('instanceNic-0'), '2016-09-01').ipConfigurations[0].properties.privateIPAddress]"
    }
}

因此，您可以为每个实例id设置变量，然后获取私有IP地址，模板的部分如下所示：

/subscriptions/{subscriptionId}/resourceGroups/{groupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmssName}/virtualMachines/{instanceId}/networkInterfaces/{nicName}

"variables": {
    "instanceNic-0": "[concat('/subscriptions/{subscriptionId}/resourceGroups/{groupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmssName}/virtualMachines/0/networkInterfaces/', parameters('nicName'))]" 
},
"outputs": {
    "instanceNic-0-IP": {
        "type": "string",
        "value": "[reference(variables('instanceNic-0'), '2016-09-01').ipConfigurations[0].properties.privateIPAddress]"
    }
}
