Lighthouse

Lighthouse is a simple service-discovery tool for Akka.Cluster, designed to make it easier to place nice with PaaS deployments like Azure / Elastic Beanstalk / AppHarbor.

Running on .NET 4.5

Lighthouse runs on Akka.NET version 1.3.1, which supports .NET 4.5 and .NET Core 1.1/.NET Standard 1.6. To package the executable and run the .NET 4.5 version locally, clone this repo and build the Lighthouse project. Running Lighthouse.exe in a console should produce an output similar to this:

Topshelf.HostFactory: Configuration Result:
[Success] Name Lighthouse
[Success] DisplayName Lighthouse Service Discovery
[Success] Description Lighthouse Service Discovery for Akka.NET Clusters
[Success] ServiceName Lighthouse
Topshelf.HostConfigurators.HostConfiguratorImpl: Topshelf v3.2.150.0, .NET Framework v4.0.30319.42000

The Lighthouse .NET 4.5 project is built as a Topshelf service. This allows you to install Lighthouse as a Windows Service using a command like this:

Lighthouse.exe install --localsystem --autostart

See the Topshelf documentation for more info on command line arguments for installing a Topshelf service.

Running on .NET Core

Lighthouse also includes a .NET Core-compatible version under a separate project named Lighthouse.NetCoreApp. This project does not build as a Topshelf web service. You have 2 ways that you can run this version:

• using the .NET CLI
• building the project as a standalone .exe for your specific runtime identifier

Using the .NET CLI

Build the project either in Visual Studio 2017 or using dotnet build -c Release Lighthouse.NetCoreApp.csproj. This will output Lighthouse.NetCoreApp.dll in your bin/Release folder. From there, running dotnet ./Lighthouse.NetCoreApp.dll will start Lighthouse. Pressing Enter will exit.

Building the project as an .exe

You need to restore the dependencies for the target runtime identifier that you want to build the executable for:

dotnet restore -r win7-x64

Then, you may publish the executable using the command:

dotnet publish -c Release -r win7-x64 -f netcoreapp1.1

This will include a publish folder in your bin directory that will include the .exe and the .NET Core runtime dependencies:

bin/
	Release/
		netcoreapp1.1/
			win7-x64/
				publish/
					Lighthouse.NetCoreApp.exe
