title: Display trace and debug messages from the docker logs console for ASP.NET Core apps
body: <p>I have a <a href="https://github.com/justaprogrammer/JustAProgrammer.AspNetCore.Auth.SslProxy" rel="nofollow noreferrer">fairly standard ASP.NET MVC App</a> that I am serving through the basic Linux docker image. It happens to have a separate ssl reverse proxy, but that's irrevelant to this issue.</p>
  
  <p>I have logging in Appsettings.Development.json set like this:</p>
  
  <pre><code>"Logging": {
    "IncludeScopes": true,
    "LogLevel": {
      "Default": "Trace",
      "System": "Information",
      "Microsoft": "Information",
      "JustAProgrammer.AspNetCore.Auth.SslProxy.Extensions": "Trace",
      "Microsoft.AspNetCore.Authentication": "Trace",
      "Microsoft.IdentityModel": "Trace"
    }
  }
  </code></pre>
  
  <p>I have trace and debug messages all over my code. They show up in the debug console in Visual studio. However, if I just do a <code>docker-compose run</code> or a <code>docker-compose logs</code> I only see <code>info</code> and <code>warn</code> messages. Is there another place I need to set logging preferences on Linux docker images?</p>
