通过ARM模板创建.NET 5功能应用程序后的“服务不可用”

Question

我尝试在ARM模板中复制以下Azure命令。它基于文档，工作良好。

az functionapp create --resource-group AzureFunctionsQuickstart-rg --p myappserviceplan --runtime dotnet-isolated --runtime-version 5.0 --functions-version 3 --name <APP_NAME> --storage-account <STORAGE_NAME> --os-type linux

但是，在执行下面的ARM模板时，我打开https://.azurewebsites.net后得到的只有Service unavailable。如果我使用AZ命令，我会看到Your Functions 3.0 app is up and running。通过func azure functionapp publish或Azure管道发布我的函数似乎大部分时间都是超时的，特别是使用Azure函数应用程序任务的Azure管道。

我需要改变什么？

解决方案是向模板中添加附加的小参数"linuxFxVersion": "DOTNET-ISOLATED|5.0"。我过去只在通过Azure管道部署我的应用程序时才设置它，但是现在似乎没有它也会阻止您的部署。

工作臂模板：
