[英]ASP.NET Core 2.0 Error starting Kestrel in Kubernetes
创建了一个新的ASP.NET Core 2.0项目,它在本地运行良好。 然后在本地运行Docker容器后它也可以正常工作。 但是当我尝试在Kubernetes pod中使用Docker镜像时,它会运行几分钟然后给我这个:
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()
这是我的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" });
});
}
}
当发生此错误时,我们使用FROM microsoft/aspnetcore-build:1.1
基本映像作为构建和运行时。 当我们遇到错误时,我们只是尝试升级到FROM microsoft/aspnetcore-build:2.0
。 我不确定这个图像的具体问题是什么,但Kubernetes不喜欢它。
稍后,我们将dockerfile切换为多级; 使用FROM microsoft/aspnetcore-build:1.1
并使用FROM microsoft/dotnet:1.1-runtime
,当我们将其升级到相应的2.0版本时,我们没有再遇到此错误。
