json - 如何通过 ARM 模板在应用程序网关中创建 backendAddressPools、frontendports 的多个实例

Question

我正在通过 ARM 模板创建应用程序网关，引用 - Create Application Gateway v2我想为应用程序网关创建属性的多个实例，即上述模板中的“backendAddressPools”、“backendHttpSettingsCollection”等。无法通过“复制”创建多个实例。

尝试按照 - multipleinstances 中提供的示例实现，在 Azure DevOps 管道中执行时显示以下错误。

Unable to process template language expressions for resource '/subscriptions/XXXXXX/resourceGroups/rsgAppGw/providers/Microsoft.Network/applicationGateways/appGwV2' at line '1' and column '2537'. 'The template function 'copyIndex' is not expected at this location. The function can only be used in a resource with copy specified..

想要创建为应用程序网关提供的属性的多个实例。

Answer 1

这是我一直在做的一个例子:

{
    "apiVersion": "2018-04-01",
    "name": "[deployment().name]",
    "type": "Microsoft.Network/applicationGateways",
    "location": "[resourceGroup().location]",
    "properties": {
        "copy": [
            {
                "name": "backendAddressPools",
                "count": "[length(parameters('backendAddressPools'))]",
                "input": {
                    "name": "[parameters('backendAddressPools')[copyIndex('backendAddressPools')].name]",
                    "properties": "[parameters('backendIPAddresses')[copyIndex('backendAddressPools')]]"
                }
            }
        ]
    }
}

这只是您需要适应您的需求的示例，但它展示了这个想法，您需要使用 properties 属性 (doh) 内的复制功能并定义您想要获得的内容。我已经为您定义了 backendAddressPools ，它应该或多或少地根据我认为您想要的功能工作(我可能是错的，所以可能需要在这里稍微修改一下)。
