我是ARM模板的新手。使用1个托管数据磁盘构建VM之后，我已从门户网站下载了ARM模板。我的目标是使用ARM模板连续构建多个VM。目前，具有相同的参数，除了虚拟机名称，当然还有网卡和磁盘名称。我注意到parameters.json文件具有硬编码的值，因此无法作为模板使用，因此我开始进行修改以查看如何使其更具动态性。但是，我不了解数据磁盘结构，该模板在此模板中将其划分为不同的组件，这使我难以使用磁盘的动态命名。
数据磁盘在模板中显示为模板中的资源，然后作为VM的属性。但是，在参数文件中有两个对象，即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内的所有内容而不是dataDisksResources），并且我也不明白为什么VM disk属性的参数不同并且比磁盘资源的参数。
这是template.json

我也找不到此类模板的任何文档。我发现的所有快速模板都有一个简单的版本。例如，它们声明同一模板文件中的所有磁盘属性，参数和属性较少，并且任何地方都不存在任何dataDisksResources对象。
[我想了解如何修改这些磁盘结构以添加动态命名来命名它们，例如，就像Azure门户（VMName_DataDisk_Lunnumber）一样]
因为在创建数据磁盘和附加数据磁盘时必须指定不同的输入，但是不必创建它，所以只需告诉VM创建它们。 thsis是做到这一点的一种方法：
"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"
}
],
并且您不必具有单独的磁盘资源，它们将自动创建。您还可以添加一个名为name的属性来为其指定名称。
