Arm模板复制循环有条件地检查索引

Question

ARM模板中是否存在有条件的复制迭代检查选项？例如，如果复制索引为零，是否设置另一个值？

我的ARM代码：

{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"location": {
"type": "string",
"defaultValue": "[resourceGroup().location]"
},
"storageAccountName": {
"type": "string"
},
"mediaServicesAccountName": {
"type": "string"
}
},
"functions": [],
"resources": [
{
"type": "Microsoft.Storage/storageAccounts",
"apiVersion": "2021-01-01",
"name": "[concat('storage', copyIndex(), uniqueString(resourceGroup().id))]",
"location": "[parameters('location')]",
"sku": {
"name": "Standard_LRS"
},
"kind": "StorageV2",
"copy": {
"name": "storagecopy",
"count": 3
}
},
{
"type": "Microsoft.Media/mediaservices",
"apiVersion": "2020-05-01",
"name": "[parameters('mediaServicesAccountName')]",
"location": "[parameters('location')]",
"properties": {
"storageAccounts": [
{
"type": "Primary", # Primary if copyIndex is zero otherwise Secondary
"id": "[resourceId('Microsoft.Storage/storageAccounts', concat('storage', copyIndex(), uniqueString(resourceGroup().id)))]"
}
]
},
"identity": {
"type": "SystemAssigned"
},
"dependsOn": ["storagecopy"]
}
],
"metadata": {
"_generator": {
"name": "bicep",
"version": "0.3.126.58533",
"templateHash": "2006367938138350540"
}
}
}

在上面的代码中，我创建了3个存储帐户，之后我创建了azure媒体服务，我需要将存储帐户动态映射到azure媒体服务。在属性下，如果索引为零，我需要使用复制循环并设置Primary，否则为定义的存储数量设置Secondary。

复制循环条件需要以下块实现：

"storageAccounts": [
{
"type": "Primary", # Primary if copyIndex is zero otherwise Secondary
"id": "[resourceId('Microsoft.Storage/storageAccounts', concat('storage', copyIndex(), uniqueString(resourceGroup().id)))]"
}
]

您需要在storageAccounts属性上进行单独的循环：

{
"type": "Microsoft.Media/mediaservices",
"apiVersion": "2020-05-01",
...
"properties": {
"copy": [
{
"name": "storageAccounts",
"count": "3",
"input": {
"type": "[if(equals(copyIndex('storageAccounts'), 0), 'Primary', 'Secondary']", # Primary if copyIndex is zero otherwise Secondary
"id": "[resourceId('Microsoft.Storage/storageAccounts', concat('storage', copyIndex('storageAccounts'), uniqueString(resourceGroup().id)))]"
}
}
]
}
}
