解析 Azure ARM 模板文件中的变量

Question

我正在编写用于部署 VNET 的 Azure ARM 模板。因此我有一个部署文件“VNET.json”和一个参数文件“VNET.parameter.json。

现在我只想在参数文件中交出一个变量，但总是出错：

'The template variable 'IP' is not found. Please see https://aka.ms/arm-template/#variables for usage details.

或者是不是“允许”在参数中使用变量？

这是我的 json 文件。

Answer 1

在模板中，你reference the value for the parameter by using the variables函数。

在 ARM 模板 json 文件中，您使用变量来简化模板。您无需在整个模板中重复复杂的表达式，而是定义一个包含复杂表达式的变量。但是，如果只使用一次就不需要使用变量了。

另外，正如 usrone 所说，您的模板看起来很可疑。正常的template 就是你可以参考的这个。

{
  "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
  "contentVersion": "",
  "apiProfile": "",
  "parameters": {  },
  "variables": {  },
  "functions": [  ],
  "resources": [  ],
  "outputs": {  }
}
