Celery exiting with code 0 after starting workers

Guys, please help me find where the problem can be? Workers are starting fine and then celery just dies without a reason and even exit code 0

This is celery part in docker-compose.yml

celery:
  build:
    context: ./backend
    dockerfile: ./celeryDockerfile
  container_name: celery
  env_file: .env
  healthcheck:
    test: celery -b amqp://${RABBITMQ_USER}:${RABBITMQ_PASS}@rabbit status || exit 1
    interval: 5s
    timeout: 10s
    retries: 3
  entrypoint: [ "/app/celery-entrypoint.sh" ]
  command: celery multi start 2 --logfile=logs/celery.log -l INFO
  depends_on:
    backend:
      condition: service_healthy
    rabbit:
      condition: service_healthy

And this is log output

celery     | celery started
celery     | celery multi v5.4.0 (opalescent)
celery     | > Starting nodes...
celery     |    > celery1@3e42fac37fa0: OK
celery     |    > celery2@3e42fac37fa0: OK

Ignore the entrypoint part there is only echo celery started inside

Turns out celery multi runs and then exits so i found this gist to help with my problem.

To summarize what does code from the gist do:

1. Start the workers with celery multi start and related parameters
2. Start trapping signals using trap to capture TERM and INT signals
3. Start tail -f for logs to redirect them into console
4. Capture tail -f's PID
5. wait "$child" will allowing to redirect logs indefinitely and capture any signal i.e TERM
6. There is a teardown function to kill celery workers with celery multi stop and kill tail -f process with it's PID
