我正在尝试使用下面的链接https://github.com/Azure/azure-quickstart-templates/tree/master/cloudera-on-centos在azure上安装cloudera，这给了我错误 “消息”：“部署模板验证失败：'493'行和'9'列上的模板资源'主节点'无效：在此位置不应使用模板函数'copyIndex'。该函数只能可以在指定了副本的资源中使用。有关用法的详细信息，请参见https://aka.ms/arm-copy。.有关用法的详细信息，请参见https://aka.ms/arm-template-expressions

答案 0 :(得分：0)
是的，我已经找到了问题所在（可悲的是，此后可能还会有更多问题）。问题来自您正在使用嵌套的INLINE模板以及它们如何（或不可以）与参考函数一起工作：
"[reference(concat(variables('publicIPAddressName'), copyIndex())).dnsSettings.fqdn]",
这是多数民众赞成在打破的部分。因此，我的建议是将其设为单个模板而不嵌套它们，或者将其转换为完整的嵌套模板（使用templateLink属性，而不是template属性：
{
"name": "name",
"type": "Microsoft.Resources/deployments",
"apiVersion": "2017-05-10",
"properties": {
"mode": "Incremental",
"templateLink": {
"uri": "url_goes_here"
},
"parameters": {
"prefix": {
"value": "xxx"
}
}
}
},
我建议您不要使用嵌套的INLINE模板。他们太前卫了。
