我使用 TopShelf 创建了一个 .net 核心控制台应用程序。但是在使用 docker (alpine-linux) 运行应用程序时出现错误。

Configuration Result:
    [Success] Name MyApp
    [Success] DisplayName MyApp
    [Success] Description My Application
    [Success] ServiceName MyApp

我尝试向我的控制台应用程序添加一个记录器。所有配置都正确应用，除了Logging

程序.cs：

   private static void Main(string[] args)
    {
        var services = new ServiceCollection();
        ConfigureServices(services);

        var serviceProvider = services.BuildServiceProvider();

        serviceProvider.GetService<App>().Run();
        Console.ReadKey();
    }

    private static void ConfigureServices(ServiceCollection services)
    {

        var envName = Environment.GetEnvironmentVariable("MY_ENV") ?? DevelopmentEnvName;

        var configuration = new ConfigurationBuilder()
                            .SetBasePath(Directory.GetCurrentDirectory())
                            .AddJsonFile("appsettings.json", false)
                            .AddJsonFile($"appsettings.{envName}.json", true, true)
                            .AddEnvironmentVariables()
                            .Build();

        services.AddSingleton(configuration);
        services.AddLogging(builder =>
                            {
                                builder.AddConfiguration(configuration)
                                       .AddConsole()
                                       .AddDebug();
                            });

        ConfigureOptions(services, configuration);

        ConfigureDependencies(services);
    }

在App.Run()我尝试记录调试和信息消息

 public void Run()
 {
    _logger.LogDebug("Debug");
    _logger.LogDebug(_appOptions.Env);   //print nothing

    _logger.LogInformation("Info");
    _logger.LogInformation(_appOptions.Env);  //print Info and debug env lines
 }

appsettings.json： …

我有一个 .NET Core 3.0 控制台应用程序。我有一个 Microsoft.Extensions.Logging 记录器，并且正在使用命令行参数构建 Microsoft.Extensions.Configuration。

我的问题是“如何通过命令行参数设置日志级别？”

这篇文章https://medium.com/@dmitryzaets/legacy-net-applications-configuration-management-net-framework-4-5-1-68220335d9d8描述了如何将选项模式与 Autofac 一起使用。我试图将其翻译为与 Simple Injector 一起使用。但我没有运气。这是我的国际奥委会代码

            .SetBasePath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "Configuration"))
            .AddJsonFile("settings.json", optional: false, reloadOnChange: true);
        var configuration = configurationBuilder.Build();
        //Register Options
        Container.Register(typeof(IOptions<>), typeof(OptionsManager<>));
