Overlord

Quick and simple automated game server deployment.

This project is under heavy development and will introduce breaking changes without prior warning or promises of backwards compatibility - Use at your own risk

Running in Standalone Mode

For instance, to start a Minecraft server using the default server definition:

$ java -jar overlord-agent.jar standalone examples/minecraft.yaml

Most aspects of the definition file are self-explanatory. Refer to the examples directory for comprehensive configuration examples.

Running in RPC Mode

When executed in RPC mode, the Overlord agent provides you with the ability to remotely provision and control a server instance of your choosing.

Note: This feature is primarily aimed at developers who wish to leverage the server deployment capabilities within an automated environment of their choosing and thus lacks user facing documentation. For a full listing of available methods, refer to th gRPC service definitions.

$ java -jar overlord-agent.jar rpc-server

For maintenance and evaluation purposes, the following RPC client commands are provided as well:

$ java -jar overlord-agent.jar rpc provision examples/minecraft.yaml
$ java -jar overlord-agent.jar rpc start
$ java -jar overlord-agent.jar rpc stop

Note: The RPC commands are provided as a convenience and do not provide any stability guarantee or fancy error handling. If you wish to automate a deployment process, please make use of the provided gRPC definitions (these definitions may also be used to generate bindings for languages outside of the Java ecosystem).
