NoGameSpy-Vietcong

Crawls servers hosting multi-player game and saves information via ORM into DB. Acts as an alternative master server.

Usage

Needed: Docker, Docker Compose

You also need to have the docker-compose.yml file from this repository locally.

Run docker-compose run master alembic upgrade head to upgrade the DB schema. It needs to be run before the first use and on every change of the schema.

Run docker-compose up to start all services. Ctrl+C to exit.

If you want them demonized, use docker-compose up -d and docker-compose down.

Workers can be scaled by calling docker-compose up --scale celery_worker=<number>.

Published ports are:

• 28900 TCP for the master server (game clients fetch the servers list here)
• 27900 UDP for the heartbeat service (game servers introduce themselves here)

Configuration

Optionally, use these environment variables (they can be in the .env file):

# PostgreSQL:
DATABASE='postgresql://<user>:<password>@<host>[:<port>]/<dbname>[?<options>]'

# MySQL:
DATABASE='mysql+pymysql://<user>:<password>@<host>[:<port>]/<dbname>[?<options>]'

# Logging aggregation:
SENTRY_DSN='https://<token>@sentry.io/<project>'

# Counting statistics:
STATSD_HOST='...'
STATSD_PORT=8125

Development

./dev.sh build master

./dev.sh run master ./test.sh

./dev.sh run master ./app.py --help

Under ./dev.sh run master bash:

alembic revision [--autogenerate] -m "<migration message>" (creates a new DB migration)

alembic upgrade head (needs to be rerun every time a DB migration is released)
