通过数组运行的 Azure 模板

Question

我对使用 azure 模板进行部署相当陌生，并且一直在开发一个部署一组虚拟机的模板。在模板的第一次迭代中，我将其设置为读取参数文件并将虚拟机名称指定为参数 - 此参数用于形成 NIC 名称以及 OS 磁盘名称。

我现在尝试做的是设置模板以根据参数中的数组创建多个虚拟机。

我已经设置了参数

    "virtualMachineName": {
        "type": "array",
        "defaultValue": [
            "VM-WEB01",
            "VM-WEB02"
        ]

然后在模板文件中我引用它类似于此

"networkInterfaceName":  "[concat(toUpper(parameters('virtualMachineName')[copyIndex()]),'-NIC')]"
"name": "[concat(parameters('virtualMachineName')[copyIndex()],'-osDisk')]",

等等。

然后我在资源部分的末尾使用了复制选项，但在模板中的输出部分之前

 "copy": {
        "name": "vmcopy",
        "count": "[length(parameters('virtualMachineName'))]"
      }

在尝试部署模板时，我收到一条错误消息，指出 virtualMachineName 参数为空。

任何我出错的地方都将不胜感激。

这是完整的模板

Answer 1

原则上这应该没问题，因为您没有提供整个模板，因此很难准确判断出了什么问题，但是您应该能够通过修改 here 的基本示例并使用您的位来制作一个工作示例示例中的一个（您还需要将参数固定为数组）：

"copy": {
    "name": "vmcopy",
    "count": "[length(parameters('virtualMachineName'))]"
}

修复应该是这样的：

{
    "apiVersion": "2017-05-10",
    "name": "[concat(parameters('virtualMachineName')[copyIndex()], '-' , 'BackupIntent')]",
    "type": "Microsoft.Resources/deployments",
    "resourceGroup": "[parameters('backupVaultRGName')]",
    "properties": {
        "mode": "Incremental",
        "template": {
            "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
            "contentVersion": "1.0.0.0",
            "resources": [
                {
                    "name": "[concat(parameters('backupVaultName'), '/', parameters('backupFabricName'), '/', parameters('backupItemName'))]",
                    "apiVersion": "2017-07-01",

                        "friendlyName": "[concat(parameters('virtualMachineName')[copyIndex()], 'BackupIntent')]",
                        "protectionIntentItemType": "AzureResourceItem",
                        "policyId": "[resourceId(parameters('backupVaultRGName'), 'Microsoft.RecoveryServices/vaults/backupPolicies', parameters('backupVaultName'), parameters('backupPolicyName'))]",
                        "sourceResourceId": "[resourceId(parameters('virtualMachineRG'), 'Microsoft.Compute/virtualMachines', parameters('virtualMachineName')[copyIndex()])]"
                    }
                }
            ]
        }
    },
    "copy": {
        "name": "vmNICCopy",
