我如何在copyIndex（数组）资源上使用dependsOn？

Question

我正在使用手臂模板来部署主题和订阅。我要部署的资源为Microsoft.Resources/deployments类型，因为我的目标是部署所在外部的资源组。

如果主题已经存在，则模板可以工作。由于arm模板资源是并行部署的，因此我需要让主题部署之前订阅-this ordering is made possible by dependsOn。

我遇到的问题是，因为主题的dependsOn值具有"name"，所以我不确定如何定位主题资源。

我尝试过的很多东西中，有一些：

• copyIndex()
• [concat(parameters('serviceBusNamespaceName'), '/', parameters('subscriptions')[copyIndex()].topic)]

• [resourceId('Microsoft.Resources/deployments',
  parameters('topics'))]

以下是模板中的主题和订阅资源对象：

["topicLoop"]

是，如果可以生成每个名称，则可以对每个单独的资源使用

        {
            "apiVersion": "2018-02-01",
            "type": "Microsoft.Resources/deployments",
            "name": "[concat(parameters('serviceBusNamespaceName'), copyIndex())]",
            "resourceGroup": "[parameters('sharedResourcesResourceGroupName')]",
            "copy": {
                "name": "topicLoop",
                "count": "[length(parameters('topics'))]"
            },
            "properties": {
                "mode": "Incremental",
                "template": {
                    "$schema": "2018-05-01",
                    "contentVersion": "1.0.0.0",
                    "resources": [
                        {
                            "type": "Microsoft.ServiceBus/namespaces/topics",
                            "name": "[concat(parameters('serviceBusNamespaceName'), '/', parameters('topics')[copyIndex()])]",
                            "apiVersion": "2017-04-01",
                            "location": "[resourceGroup().location]",
                            "properties": {}                  
                        }
                    ]
                }
            }
        },
        {
            "apiVersion": "2018-02-01",
            "type": "Microsoft.Resources/deployments",
            "name": "[concat(parameters('subscriptions')[copyIndex()].topic, copyIndex())]",
            "resourceGroup": "[parameters('sharedResourcesResourceGroupName')]",
            "copy": {
                "name": "subscriptionLoop",
                "count": "[length(parameters('subscriptions'))]"
            },
            "properties": {
                "mode": "Incremental",
                "template": {
                    "$schema": "2018-05-01",
                    "contentVersion": "1.0.0.0",
                    "resources": [
                        {
                            "type": "Microsoft.ServiceBus/namespaces/topics/subscriptions",
                            "name": "[concat(parameters('serviceBusNamespaceName'), '/', parameters('subscriptions')[copyIndex()].topic, '/', parameters('subscriptions')[copyIndex()].subscription)]",
                            "apiVersion": "2017-04-01",
                            "location": "[resourceGroup().location]",
                            "properties": {}          
                        }
                    ]
                }
            },
            "dependsOn": [
                // what goes here?! I need to have this depend on the topics 
            ]
        }

。或者您可以对它们进行硬编码。无论哪种方式，您都可以使用其名称来dependsOn整个循环，或者通过使用其名称引用它们来循环内部的单个资源

dependsOn值很简单：
