在我的 yml 文件中

ports:
      - "80"
      - "9000"
      - "8080:9000"

我错过了什么？

Answer 1

This is a limitation of the Azure Web App, it only supports to expose the port 80 and 443. So when you want to expose other ports such as 9000 and 8080, then you got the error that it didn't respond to HTTP pings on那个港口。

Answer 2

感谢您的回答，基本上就是Charles Xu所说的。 为了解决这个问题，我刚刚在 Dockerfile 中暴露了端口 80 和 9000，最后在 Azure 应用程序设置中添加了两个新变量，PORT=9000 和 WEBSITES_PORT=80。

Answer 3

Azure Web Apps 80和443端口限制解除：

https://learn.microsoft.com/en-us/azure/app-service/configure-custom-container?pivots=container-linux&tabs=debian#configure-port-number

Azure 命令行界面：

az webapp config appsettings set --resource-group <group-name> --name <app-name> --settings WEBSITES_PORT=8000

Azure Powershell：

Set-AzWebApp -ResourceGroupName <group-name> -Name <app-name> -AppSettings @{"WEBSITES_PORT"="8000"}
