如何在不破坏 ARM 模板的情况下将资源组名称添加到 redis 名称？

Question

我正在尝试通过 ARM 模板部署 Redis 并保持 Redis 主机名的唯一性，我在其前面加上资源组名称：

"variables": {
    "resourceName": "[concat(resourceGroup().id, '-', parameters('redisCacheName'))]"
},

然而我突然得到以下错误，搜索给出了截然不同的答案：

Deployment template validation failed: 'The template resource '/subscriptions/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX/resourceGroups/my-group-my-redis' for type 'Microsoft.WindowsAzure.ResourceStack.Frontdoor.Common.Entities.TemplateGenericProperty`1[System.String]' at line '1' and column '640' has incorrect segment lengths.

A nested resource type must have identical number of segments as its resource name. A root resource type must have segment length one greater than its resource name. Please see https://aka.ms/arm-template/#resources for usage details.'.

我不明白为什么在尝试部署基本 Redis 实例时会提到一些“Frontdoor”，请问这里的修复是什么？

下面是我的 ARM 模板：

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "redisCacheName": {
            "defaultValue": "my-redis",
            "type": "String"
        }
    },
    "variables": {
        "resourceName": "[concat(resourceGroup().id, '-', parameters('redisCacheName'))]"
    },
    "outputs": {
      "RedisCacheEndpoint": {
        "type": "string",
        "value": "[concat(reference(variables('resourceName')).hostName, ':', reference(variables('resourceName')).sslPort)]"
      },
      "RedisCachePassword": {
        "type": "string",
        "value": "[reference(variables('resourceName')).accessKeys.primaryKey]"
      }
    },
    "resources": [
        {
            "type": "Microsoft.Cache/Redis",
            "apiVersion": "2019-07-01",
            "name": "[variables('resourceName')]",
            "location": "[resourceGroup().location]",
            "properties": {
                "sku": {
                    "name": "Basic",
                    "family": "C",
                    "capacity": 1
                },
                "enableNonSslPort": false
            }
        }
    ]
}

这里是参数文件：

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "redisCacheName": {
            "value": "my-redis"
        }
    }
}

我正在尝试将 Redis 实例部署到名为“my-group”的 RG 中，并且在部署时我使用参数值“my-redis”-

同时希望 Redis 端点的唯一名称为“my-group-my-redis.redis.cache.windows.net:6380”。

你用错了方法，你应该用这个：

 "[concat(resourceGroup().name, '-', parameters('redisCacheName'))]"
