ASP.NET Core 2.0 Error Starting Kestrel in Kubernet

Question

Created a new ASP.NET Core 2.0 project, and it works great locally. Then, after running in the Docker container, it also works fine. But when I try to use the Docker image in the Kubernetes module, it will work for a couple of minutes, and then give me the following:

Unhandled Exception: System.InvalidOperationException: A path base can only be configured using IApplicationBuilder.UsePathBase(). at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.AddressBinder. <BindAddressAsync>d__7.MoveNext() 

Here is my Program.cs :

 public class Program { public static void Main(string[] args) { BuildWebHost(args).Run(); } public static IWebHost BuildWebHost(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .Build(); } 

Startup.cs :

 public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { services.AddMvc(); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions { HotModuleReplacement = true, ReactHotModuleReplacement = true }); } else { app.UseExceptionHandler("/Home/Error"); } app.UseStaticFiles(); app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); routes.MapSpaFallbackRoute( name: "spa-fallback", defaults: new { controller = "Home", action = "Index" }); }); } }
