Components

Team server

Team server (team-server/main.py) mediates between agents, listeners and clients.

Client

Client (client/main.py) is the client to use to connect to Team server.

Listener

Listeners (team-server/listeners/*.py) are scripts that start a server, intended to receive communication from agents. They are part of team server since they are started on team server.

Database

There's a MySQL database in team-server/database that needs to be setup with docker. This database stores all necessary persistent information.

Team server guide

Note: All team server stuff is in team-server/ directory. Unless otherwise stated, use this folder as your current directory when starting the team server.

Environment variables

Create a .env file (use .env.example as a template) for usage.

Starting MySQL database

Once done, start the database:

docker compose up -f ./database/compose.yaml -d # starts MySQL in a docker and performs database setup

This starts a local (127.0.0.1:3306) MySQL database, with your chosen username and password in .env. Use this if you need to manually interact with the database.

Starting team server

python3 -m virtualenv venv
source ./venv/bin/activate

python3 ./main.py -H 127.0.0.1 -P 6060

Stopping team server

Ctrl + C # yes, just interrupt

Stopping MySQL database

docker compose down -f ./database/compose.yaml -d

Removing MySQL volume

sudo docker volume rm team-server_hydrangea-mysql # remove MySQL's docker volume

Client guide

Note: All client stuff is in client/ directory. Unless otherwise stated, use this folder as your current directory when starting the client.

Starting client

python3 ./main.py -H 127.0.0.1 -P 6060
