Azure ARM 模板用户定义函数

Question

我需要创建 8 个数据库和几个集合，尽管 ARM template.I 在这里通过用户定义的函数 https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/template-user-defined-functions 使模板更简单，这是我可以实现而不是复制的东西吗粘贴相同的脚本？现在，它抛出一个错误

Template validation failed: Unexpected initial token 'String' when populating object.

我目前的职能：

"functions": [
    {
      "namespace": "contoso",
      "members": {
        "uniqueName": {
          "parameters": [
            {
              "name": "databaseName",
              "type": "string"
            }
          ],
          "output": {
            "type": "object",
            "value": {
              "type": "Microsoft.DocumentDB/databaseAccounts/mongodbDatabases",
              "name": "['test', '/', parameters('databaseName'))]",
              "apiVersion": "2020-04-01",
              "dependsOn": [ "[resourceId('Microsoft.DocumentDB/databaseAccounts/', 'test')]" ],
              "properties": {
                "resource": {
                  "id": "[parameters('databaseName')]"
                }
              }
            }
          }
        }
      }
    }
  ],

我们能做到吗？

您似乎正试图在 databaseAccounts 资源中创建多个 mongodbDatabases。

我建议查看 ARM copy 元素。 https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/copy-resources#resource-iteration

大致如下：

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "accountName": {
      "type": "string",
      "defaultValue": "test",
      "metadata": {
        "description": "Cosmos DB account name"
      }
    },
    "databaseNames": {
      "type": "array",
      "defaultValue": [
        "contoso",
        "fabrikam",
        "coho"
      ],
      "metadata": {
        "description": "Cosmos DB database names array"
      }
    }
  },
  "resources": [
    {
      "type": "Microsoft.DocumentDB/databaseAccounts",
      "name": "[parameters('accountName')]",
      "apiVersion": "2020-04-01",
      "location": "central us",
      "kind": "MongoDB",
      "properties": {
        "isVirtualNetworkFilterEnabled": false,
        "databaseAccountOfferType": "Standard",
        "apiProperties": {
          "serverVersion": "3.6"
        }
      }
    },
    {
      "type": "Microsoft.DocumentDB/databaseAccounts/mongodbDatabases",
      "name": "[concat('/test', '/', parameters('databaseNames')[copyIndex()])]",
      "apiVersion": "2020-04-01",
      "dependsOn": [ "[resourceId('Microsoft.DocumentDB/databaseAccounts/', 'test')]" ],
      "properties": {
        "resource": {
          "id": "[parameters('databaseNames')[copyIndex()]]"
        }
      },
      "copy": {
        "name": "databaseCopy",
        "count": "[length(parameters('databaseNames'))]"
      }
    }
  ]
}
