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，我从门户网站下载了一个 ARM 模板。我的objective是用ARM Templates连续搭建好几个VM。现在，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 文件有硬编码值，不能用作模板，所以我开始修改以查看如何使它更动态。但是我不明白数据磁盘结构，在这个模板中，数据磁盘结构被划分为不同的组件，这让我很难为磁盘动态命名。

数据磁盘在模板中作为资源出现，然后作为 VM 的属性在复制函数中出现。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也有 dataDisksResources）而且我也不明白为什么 VM 磁盘属性的参数不同并且不止是Disk Resource的参数。

这是template.json

我也找不到此类模板的任何文档。我找到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，参数和属性更少，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命名它们的动态命名，例如，就像 Azure 门户一样 (VMName_DataDisk_Lunnumber)

因为创建数据盘和附加数据盘时必须指定不同的输入，但你不必创建它，你可以告诉虚拟机创建它们。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"
        }
      ],

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