Aspire.Hosting.Yarp

This is a sample project that shows how use YARP in development to route between multiple services.

Getting Started

There are 2 ways to use the YARP resource:

1. Code based routes

var builder = DistributedApplication.CreateBuilder(args);

var app1 = builder.AddProject<Projects.WebApplication1>("app1");

var app2 = builder.AddProject<Projects.WebApplication2>("app2");

builder.AddYarp("ingress")
       .WithEndpoint(hostPort: 8001, scheme: "http")
       .Route("app1", path: "/app1", target: app1)
       .Route("app2", path: "/app2", target: app2);

builder.Build().Run();

2. Configuration based routes

var builder = DistributedApplication.CreateBuilder(args);

var app1 = builder.AddProject<Projects.WebApplication1>("app1");

var app2 = builder.AddProject<Projects.WebApplication2>("app2");

builder.AddYarp("ingress")
    .WithEndpoint(hostPort: 8001, scheme: "http")
    .WithReference(app1)
    .WithReference(app2)
    .LoadFromConfiguration("ReverseProxy");

builder.Build().Run();
