后续的回答将帮助任何人在VS docker集成中做到这一点。我需要更改到端口8080以使用谷歌appengine中的“灵活”环境运行。

你需要在Dockerfile中添加以下内容:

ENV ASPNETCORE_URLS=http://+:8080
EXPOSE 8080

您需要在docker-compose中修改端口。Yml也是:

    ports:
      - "8080"

当托管在docker容器(linux版本的我)，你可能会得到一个'连接拒绝'消息。在这种情况下，您可以使用IP地址0.0.0.0，这意味着“这台机器上的所有IP地址”，而不是localhost环回来修复端口转发。

public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .UseUrls("http://0.0.0.0:5000/")
            .Build();

        host.Run();
    }
}

您可以指定托管URL，而不需要对应用程序进行任何更改。

创建Properties/launchSettings。Json文件，然后像这样填充它:

{
  "profiles": {
    "MyApp1-Dev": {
        "commandName": "Project",
        "environmentVariables": {
            "ASPNETCORE_ENVIRONMENT": "Development"
        },
        "applicationUrl": "http://localhost:5001/"
    }
  }
}

dotnet运行命令应该选择您的启动设置。Json文件，并将其显示在控制台中:

C:\ProjectPath [master ≡]
λ  dotnet run
Using launch settings from C:\ProjectPath\Properties\launchSettings.json...
Hosting environment: Development
Content root path: C:\ProjectPath
Now listening on: http://localhost:5001
Application started. Press Ctrl+C to shut down.

在。net Core 3.1上，只需遵循微软的文档，它非常简单:kestrel-aspnetcore-3.1

总结:

Add the below ConfigureServices section to CreateDefaultBuilder on Program.cs: // using Microsoft.Extensions.DependencyInjection; public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureServices((context, services) => { services.Configure<KestrelServerOptions>( context.Configuration.GetSection("Kestrel")); }) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); }); Add the below basic config to appsettings.json file (more config options on Microsoft article): "Kestrel": { "EndPoints": { "Http": { "Url": "http://0.0.0.0:5002" } } } Open CMD or Console on your project Publish/Debug/Release binaries folder and run: dotnet YourProject.dll Enjoy exploring your site/api at your http://localhost:5002

我用以下方法修复了Net core 3.1中的端口问题

在Program.cs中

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args)
        .ConfigureWebHost(x => x.UseUrls("https://localhost:4000", "http://localhost:4001"))
        .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); });
}

您可以使用

http://localhost:4000

https://localhost:4001
