使用JSON在Azure中创建多值标签并应用到新建资源组求助

我们可以通过两个JSON文件实现需求，可根据实际场景选择是否全局约束标签取值：

如果你不需要在整个订阅层面限制Department标签的可选值，仅需要在创建Test-RG时限定可选范围，仅使用第二部分的ARM模板即可完成需求。

1. 全局约束Department标签可选值的Azure Policy定义JSON #

该Policy会在订阅范围内生效，强制所有资源（包括资源组）的Department标签值只能从预设的四个选项中选择，避免出现不符合规范的标签值：

{
  "properties": {
    "displayName": "Allowed Department tag values",
    "policyType": "Custom",
    "mode": "Indexed",
    "description": "Restrict Department tag to predefined allowed values",
    "policyRule": {
      "if": {
        "allOf": [
          {
            "field": "tags['Department']",
            "exists": true
          },
          {
            "not": {
              "field": "tags['Department']",
              "in": [
                "Technology",
                "Finance",
                "Manufacturing",
                "Sales and Marketing"
              ]
            }
          }
        ]
      },
      "then": {
        "effect": "deny"
      }
    }
  }
}

将上述内容保存为department-tag-policy.json，分配到对应订阅后即可生效。

2. 创建带指定Department标签的Test-RG资源组ARM模板JSON #

模板内已预设Department标签的四个可选值，部署时可直接选择对应值，也可直接修改默认值为你需要的选项：

{
  "$schema": "https://schema.management.azure.com/schemas/2018-05-01/subscriptionDeploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "rgName": {
      "type": "string",
      "defaultValue": "Test-RG"
    },
    "rgLocation": {
      "type": "string",
      "defaultValue": "chinaeast2"
    },
    "departmentTagValue": {
      "type": "string",
      "allowedValues": [
        "Technology",
        "Finance",
        "Manufacturing",
        "Sales and Marketing"
      ],
      "defaultValue": "Technology"
    }
  },
  "resources": [
    {
      "type": "Microsoft.Resources/resourceGroups",
      "apiVersion": "2022-09-01",
      "name": "[parameters('rgName')]",
      "location": "[parameters('rgLocation')]",
      "tags": {
        "Department": "[parameters('departmentTagValue')]"
      }
    }
  ]
}

将上述内容保存为test-rg-deploy.json，在订阅级别部署该模板即可创建符合要求的Test-RG资源组。
