Question

我正在为CI / CD编写功能ARM模板，该功能已经托管在Azure门户上。现在，我决定创建一个ARM功能模板，并遇到以下错误。它说我无法创建已经存在的资源。我知道资源已经存在，但是我想基于模板创建CI / CD管线。我尝试了增量模式，但似乎缺少了一些东西。在线有任何指导吗？我已经从AZURE Git中获取了Azure功能模板。

C：\ Program Files \ Microsoft SDKs \ Azure.NET SDK \ v2.9> az组部署验证--mode增量--resource-group cloud-shell-storage-southeastasia --template-file azuredeploy.json < / p>

请提供'appName'的字符串值（？以获取帮助）：SchedulerHttpFunctionSample

天蓝色错误：InvalidResourceLocation 消息：资源“ SchedulerHttpFunctionSample”已经存在于资源组“ cloud-shell-storage-southeastasia”中的位置“ southcentralus”中。无法在“ southeastasia”位置创建具有相同名称的资源。请选择一个新的资源名称。

Answer 1

这是因为该名称已被使用。功能应用名称必须是全局唯一的。

我建议使用后缀。在变量部分中，创建一些变量：

"variables": {
    "suffix": "[uniqueString(resourceGroup().id, resourceGroup().location)]",
    "functionAppName": "[concat(parameters('appName'), variables('suffix'))]"
}

函数uniqueString将根据收到的信息生成一个唯一的字符串。因此，如果您在相同的资源组和区域中重新部署，则后缀将相同。
