Answer 1

Add json file called ocelot.json in your project.

Then do configure like this in Program.cs:

IConfiguration configuration = new ConfigurationBuilder()
                            .AddJsonFile("ocelot.json")
                            .Build();

var builder = WebApplication.CreateBuilder(args);
//.....
builder.Services.AddOcelot(configuration);

var app = builder.Build();

//........
app.UseOcelot();

//......

Answer 2

using Ocelot.DependencyInjection;
using Ocelot.Middleware;

var builder = WebApplication.CreateBuilder(args);

builder.Configuration.AddJsonFile("ocelot.json");

builder.Services.AddControllers();

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddOcelot();

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseOcelot().Wait();

app.UseAuthorization();

app.MapControllers();

app.Run();
