Lobby Server

The Lobby Server is a public server which handles Player authentication and lists Drafting Servers to help Players and Spectators find and join them.

Development

The Lobby Server project can be found in the NautDrafter_Lobby project in the repository.

Installation

The Lobby Server requires the following in order to run:

Java 8
Networking
- The ability to bind to a port (default 50000)
- Unfiltered network access on that port (will NOT work through a HTTP proxy)
- Persistant connections must be allowed (will NOT work through a proxy that kills idle connections)
Filesystem Access
- Must be able to write to whatever directory it is installed to. This is so it can save database files.
Config
- Requires a Steam API key in a file named STEAM_API_KEY in the installation directory. This file can be found in the private NautDrafter Installer repository.

A distributable package of the Lobby Server and its dependencies can be created by cloning the repository, and running ./gradlew NautDrafter_Lobby:disttar

Updating

To build a Lobby Server

./gradlew clean distTar

To upload a Lobby Server to the DigitalOcean instance

version=  # "0.3.0 (for stable) or 0.3.0-dev (for dev)
scp NautDrafter_Lobby/build/distributions/NautDrafter_Lobby.tar ${username}@server.nautdrafter.monky-games.com:~/lobby.tar
ssh ${username}@server.nautdrafter.monky-games.com
mkdir /opt/nautdrafter/versions/{version}
cd /opt/nautdrafter/versions/{version}
tar -xvf ~/lobby.tar
