我正在通过ARM模板创建应用程序网关，参考-Create Application Gateway v2 我想从上述模板中为应用程序网关创建多个属性实例，即“ backendAddressPools”，“ backendHttpSettingsCollection”等。无法通过“复制”创建多个实例。
尝试按照-multipleinstances中提供的示例实施，显示在Azure DevOps管道中执行时的以下错误。
无法处理资源的模板语言表达式 '/subscriptions/XXXXXX/resourceGroups/rsgAppGw/providers/Microsoft.Network/applicationGateways/appGwV2' 在“ 1”行和“ 2537”列。 '模板函数'copyIndex'是 在此位置不期望。该功能只能在 指定了副本的资源。

要创建为应用程序网关提供的属性的多个实例。

感谢@ 4c74356b41 我在我的环境中对其进行了测试，并且可以进行较小的更改。
请参阅下文，我在资源部分中使用了它：
"copy": [
{
"name": "backendAddressPools",
"count": "[length(parameters('backendAddressPoolsarray'))]",
"input": {
"name": "[parameters('backendAddressPoolsarray')[copyIndex('backendAddressPools')].name]",
"properties": {
"BackendAddresses": "[parameters('backendAddressPoolsarray')[copyIndex('backendAddressPools')].backendIPAddresses]"
}
}
}
],
这是参数文件
"backendAddressPoolsArray": {
"value": [
{
"Name": "BP1",
"backendIPAddresses": [
{
"IpAddress": "10.0.0.4"
},
{
"IpAddress": "10.0.0.5"
}
]
},
{
"Name": "BP2",
"backendIPAddresses": [
{
"IpAddress": "10.0.0.6"
},
{
"IpAddress": "10.0.0.7"
}
]
},
也不需要使用对象，数组很好

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')]]"
}
}
]
}
}
那只是您需要适应您的需求的示例，但是它展示了这个想法，您需要使用properties属性（doh）内的复制功能并定义要获取的内容。我已经为您定义了backendAddressPools，它应该根据我的想法或多或少地起作用（我可能是错的，因此可能需要在这里稍作修改）。
