Worker configuration

Worker is configured using a JSON configuration file that is mounted into the container. Create a config.json file with the worker configuration and mount it when running the container:

docker run -d -v /path/to/config.json:/app/config.json \
--name queue-worker1 \
--network emcee-network avitotech/emcee-worker:latest
