Self-hosted gRPC applications

Run your app as a Linux service with systemd

To configure your ASP.NET Core application to run as a Linux service (or daemon in Linux parlance), install the Microsoft.Extensions.Hosting.Systemd package from NuGet. Then add a call to UseSystemd to the CreateHostBuilder method in Program.cs

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .UseSystemd() // Enable running as a Systemd service
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        });

dotnet publish -c Release -r linux-x64 -o ./publish
