ARM 模板 - 将动态数据磁盘添加到 VM 的值和参数？

Question

我是 ARM 模板的新手。 在使用 1 个托管数据磁盘构建 VM 后，我从门户下载了一个 ARM 模板。 我的目标是使用 ARM 模板来连续构建多个 VM。 目前，使用相同的参数，除了 VM 名称，当然还有 NIC 和磁盘名称。 我注意到 parameters.json 文件有硬编码的值，它不能用作模板，所以我开始修改以查看如何使它更具动态性。 但是我不理解数据磁盘结构，在这个模板中，它被划分到不同的组件中，这让我为磁盘的动态命名而苦苦挣扎。

数据磁盘作为资源出现在模板中，然后作为虚拟机的属性出现在复制函数中。 但是在参数文件中有两个对象，dataDisks 和 dataDisksResources。 我不明白为什么参数有两个不同的对象而不是一个（例如，dataDisks 中的所有内容而不是 dataDisksResources），我也不明白为什么 VM 磁盘属性的参数不同，并且超过磁盘资源参数。

这是模板.json

我也找不到这种模板的任何文档。 我发现的所有快速模板都有一个更简单的版本。 例如，它们在同一个模板文件中声明了所有磁盘属性，参数和属性较少，并且任何地方都没有任何 dataDisksResources 对象。

我想了解我需要如何修改这些磁盘结构以添加动态命名来命名它们，例如 Azure 门户所做的 (VMName_DataDisk_Lunnumber)

Answer 1

因为您必须在创建数据磁盘和附加数据磁盘时指定不同的输入，但您不必创建它，所以您可以只告诉 VM 创建这些输入。 这将是这样做的一种方式：

      "dataDisks": [
        {
          "diskSizeGB": "[parameters('sizeOfEachDataDiskInGB')]",
          "lun": 0,
          "createOption": "Empty"
        },
        {
          "diskSizeGB": "[parameters('sizeOfEachDataDiskInGB')]",
          "lun": 1,
          "createOption": "Empty"
        },
        {
          "diskSizeGB": "[parameters('sizeOfEachDataDiskInGB')]",
          "lun": 2,
          "createOption": "Empty"
        },
        {
          "diskSizeGB": "[parameters('sizeOfEachDataDiskInGB')]",
          "lun": 3,
          "createOption": "Empty"
        }
      ],

并且您不必拥有单独的磁盘资源，这些将自动创建。 您还可以添加一个名为name的属性来为它们指定一个名称。
