I have three ASP.NET Core WebAPI services Customer, Subscribe, Unscubscribe with swashbuckle and docker compose project
All is working well
I have added Ocelot API Gateway (ASP.NET core Project) with Ocelot installed.

Access customer service via own address https:///api/Customer works great. But from gateway I don't know which url should I use for example this customer service
I have tried many variants like:

• http:///api/


• http:///api/a/customer


• http:///a/api/customer

but all of them returns 404.
May be problem with that Gateway is http not https?

Program.cs

public static void Main(string args)

        {

            BuildWebHost(args).Run();

        }



        public static IWebHost BuildWebHost(string args)

        {

            var builder = WebHost.CreateDefaultBuilder(args);



            builder.ConfigureServices(s => s.AddSingleton(builder))

                                                          .ConfigureAppConfiguration(

                              ic => ic.AddJsonFile(Path.Combine("configuration",

                                                                "configuration.json")))

                                                                .UseStartup<Startup>();

            var host = builder.Build();

            return host;

        }

Startup.cs

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().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

            services.AddOcelot(Configuration);

        }



        // 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();

            }

            else

            {

                app.UseHsts();

            }



            app.UseHttpsRedirection();

            app.UseMvc();

        }

You need to add UseOcelot().Wait(); in Configure method of Startup:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)

{

    if (env.IsDevelopment())

    {

        app.UseDeveloperExceptionPage();

    }

    else

    {

        app.UseHsts();

    }



    app.UseHttpsRedirection();

    app.UseMvc();

    app.UseOcelot().Wait();

}
