docker部署启动访问不了aspnet应用

[bustersword]

 public class Program
    {
        public static void Main(string[] args)
        {
            try
            {
                //貌似解决中文乱码的
                Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);

                var builder = new ServiceHostBuilder();

                var host = builder.RegisterServices((container) =>
                {

                }).UseWeb()
                .Build();

                host.Run();



            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

        }

        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }

我把原先的启动的代码放在UseWeb里了，部署到docker访问不了，但是本地直接启动是可以访问的。

docker run --name netcore-web -d -p 8999:80 core-web 启动

 public static IServiceHostBuilder UseWeb(this IServiceHostBuilder serviceHostBuilder)
        {
            var executeAss = Assembly.GetCallingAssembly();
            var path = Path.GetDirectoryName(Assembly.GetCallingAssembly().Location);
            var viewDll = Path.Combine(path, executeAss.GetName().Name + ".Views.dll");

            Assembly viewAsm = null;

            if (File.Exists(viewDll))
            {
                viewAsm = Assembly.LoadFrom(viewDll);
                
            }

            serviceHostBuilder.AddHostService((IHostBuilder hostBuilder) =>
            {
                hostBuilder.ConfigureWebHostDefaults(webHostBuilder =>
                {

                    webHostBuilder
                    .ConfigureServices(services =>
                    {
                        services.AddControllersWithViews();
                        var mvcBuilder = services.AddMvc();
                        if (viewAsm != null)
                        {
                            mvcBuilder.AddApplicationPart(viewAsm);
                        }
                        mvcBuilder.AddApplicationPart(executeAss);
                      
                    })
                    .Configure((context, app) =>
                    {
                        if (context.HostingEnvironment.IsDevelopment())
                        {
                            app.UseDeveloperExceptionPage();
                        }
                        else
                        {
                            app.UseExceptionHandler("/Home/Error");
                            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                            app.UseHsts();
                        }
                        app.UseHttpsRedirection();
                        app.UseStaticFiles();

                        app.UseRouting();

                        app.UseAuthorization();

                        app.UseEndpoints(endpoints =>
                        {
                            endpoints.MapControllerRoute(
                                name: "default",
                                pattern: "{controller=Home}/{action=Index}/{id?}");
                        });
                    });
                    
                });

            });



            return serviceHostBuilder;
        }

你是不是连接不了数据库，先看你安装的容器是否启动，你也可以调试一下你的容器，看是在那一步不行了
