Steps To Reproduce

1. Contents of Program.cs.

using System;
using System.Net;
using System.Security.Cryptography.X509Certificates;
using Microsoft.AspNetCore.Server.Kestrel.Core;

var builder = WebApplication.CreateBuilder(args);

builder.WebHost.UseKestrel(options =>
{
     // HTTP/2 Only のエンドポイント（not HTTPS）
     try{
        options.Listen(IPAddress.Parse("0.0.0.0"), 5010,
        listenOptions => { listenOptions.Protocols = HttpProtocols.Http2; });
     }
     catch(Exception e){
         Console.WriteLine(e.Message);
     }

    try{
         // 疎通確認用のHTTP 1.1エンドポイントの設定
    options.Listen(IPAddress.Parse("0.0.0.0"), 5012,
        listenOptions => { listenOptions.Protocols = HttpProtocols.Http1; });
    }
     catch(Exception e){
         Console.WriteLine(e.Message);
     }

   
});

builder.Services.AddGrpc();
builder.Services.AddMagicOnion();

var app = builder.Build();

// 疎通確認用のルーティング
app.MapGet("/", () => "Hello World!");

// MagicOnion用のルーティング
app.MapMagicOnionService();

app.Run();

2. Dockerfile and docker-compose contents.

Sorry, I had written the same thing in appsettings.json and just double activated it. So I'm closing this case.
