创建了一个新的ASP.NET Core 2.0项目,该项目在本地运行良好。
然后,在本地Docker容器中运行它之后,它也可以正常工作。但是,当我尝试在Kubernetes Pane 中使用Docker镜像时,它将运行几分钟,然后给我以下内容:
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" });
});
}
}
最佳答案
发生此错误时,我们将FROM microsoft/aspnetcore-build:1.1
基本镜像用作构建和运行时。在遇到错误时,我们只是尝试升级到FROM microsoft/aspnetcore-build:2.0
。我不确定该图像的具体问题是什么,但是Kubernetes不喜欢它。
稍后,我们将dockerfile切换为多阶段。使用FROM microsoft/aspnetcore-build:1.1
构建并运行FROM microsoft/dotnet:1.1-runtime
,并将其升级到相应的2.0版本时,我们再也没有遇到此错误。
