Boilerplate code for celery rabbitmq docker cluster

---

Version

• Docker-compose : docker-compose version 1.8.0, build unknown
• Docker : Docker version 17.12.0-ce, build c97c6d6
• Python: Python:3 docker image being used in dockerfile

---

How to run

• Run command sudo docker-compose up

• Above command will start 1 container for each worker and rabbit

• Now go inside one worker container and run python -m celery_main.task_submitter

• this will start pushing tasks in rabitmq and workers

---

Speedup the process

• To run 5 workers and 1 rabbitmq:

  sudo docker-compose up --scale worker=5

• Do not increase concurrency to too much in dockerfile as machine might not be able to handle it

  ENTRYPOINT celery -A test_celery worker --concurrency=10 --loglevel=info
