Akka.net .NET Core configuration

Question

I'm trying to configure akka.net in an ASP.NET Core 7 Web API.

I added akka.net config into appsettings.json but the configuration still does not work. What am I doing wrong? How to configure akka.net 1.5.13 in .NET 7?

{
    "akka": {
        "stdout-loglevel": "DEBUG",
        "stdout-logger-class": "Akka.Event.StandardOutLogger",
        "log-config-on-start": "off",
        "loglevel": "DEBUG",
        "loggers": [ "Akka.Logger.NLog.NLogLogger,Akka.Logger.NLog" ],
    }
}

Answer 1

builder.Services
    .AddAkka("ActorSystem", (builder, _) =>
    {
        builder.AddHoconFile("akka.hocon", HoconAddMode.Prepend)
        .WithActors((system, registry, resolver) =>
        {
          // init your actors here 
        }
    }

Your akka settings should be in the akka.hocon file.

Better way would be using Akka.Hosting since you're using WebApi.

I found a way to configure Akka.net, maybe it's not the best way, but it works.

1. Put configuration into a separate file: akka.config. Here is example of the content of this file:

   akka {
       stdout-loglevel = DEBUG
       loglevel = DEBUG
       log-config-on-start = on
   }
   

2. When you create the Actor system, you should read and parse this config and provide it to the Actor system:

   var config =
   ConfigurationFactory.ParseString(
       File.ReadAllText(Path.Combine(Environment.CurrentDirectory, "akka.config")));
   builder.Services.AddSingleton<ActorSystem>(_ => ActorSystem.Create("MySystem",config));
