Question

在Visual Studio中调试时，我的.Net Core 2.1控制台应用程序可以正常工作。日志可以很好地发布到Elastic Search并在Kabana中可见。当我尝试在容器中部署此应用程序时，没有任何日志发布到ES。同样，当我输入docker logs <container-id>时，我也看不到Docker日志-我在下面包含了我的程序类和Docker文件。我是Docker的新手，有什么明显的我想念的吗？我需要打开一些端口或其他东西吗？这样在Docker中使用appsettings.json文件可以吗？这会引起问题吗？

using System.Threading.Tasks;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using RizbotCore.BitmexTrader.Controllers;
using RizbotCore.BitmexTrader.Services;
using Serilog;
using Serilog.Sinks.Elasticsearch;

namespace RizbotCore.BitmexTrader
{
    class Program
    {
        static async Task Main(string[] args)
        {
            //setup our DI
            var serviceProvider = new ServiceCollection()
                .AddLogging()
                .AddSingleton<ITraderMain, TraderMain>()
                .BuildServiceProvider();

            // Adding JSON file into IConfiguration.
            IConfiguration config = new ConfigurationBuilder()
                 .AddJsonFile("appsettings.json", true, true)
                 .Build();

            // Read configuration
            var appSettings = config.GetSection("ElasticConfiguration");
            string esURL = appSettings["ES_URL"];

            // Set up Logging
            Log.Logger = new LoggerConfiguration()
             .MinimumLevel.Debug()
             .Enrich.FromLogContext()
             .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri(esURL))  
             {
                 AutoRegisterTemplate = true,
             })
             .CreateLogger();

            Log.Information("Starting Up...");

            // Start Main Manager
            var traderMain = serviceProvider.GetService<ITraderMain>();
            await traderMain.Start(serviceProvider);

            Console.ReadLine();
        }
    }
}

Docker文件：

您需要在dockerfile中公开所需端口，以进行所需的所有通信，即EXPOSE 80。然后，对刚刚从dockerfile中创建的映像执行docker run时，您将需要将外部暴露的端口映射到docker run -p 80:80 <yourImageName>

之外。
