Error : The support for this usage was removed in Celery 5.0. Instead you should use `--app` as a global option

I am having a fastapi when i build container image i was unable to run the celery worker

dockercompose file

version: "3.8"
services:
  web:
    build: .
    ports:
      - "8080:8000"
    command: uvicorn app.main:app --host 0.0.0.0 --reload
    environment:
      - CELERY_BROKER_URL=redis://redis:6379/0
      - CELERY_RESULT_BACKEND=redis://redis:6379/0
    depends_on:
      - redis

  worker:
    build: .
    command: celery worker --app=worker.celery --loglevel=info

    environment:
      - CELERY_BROKER_URL=redis://redis:6379/0
      - CELERY_RESULT_BACKEND=redis://redis:6379/0
    depends_on:
      - web
      - redis

  redis:
    image: redis:6-alpine

  dashboard:
    build: .
    command: flower --app=worker.celery --port=5555 --broker=redis://redis:6379/0
    ports:
      - 5556:5555
    environment:
      - CELERY_BROKER_URL=redis://redis:6379/0
      - CELERY_RESULT_BACKEND=redis://redis:6379/0
    depends_on:
      - web
      - redis
      - worker

I am getting this error You are using --app as an option of the worker sub-command

celery worker --app celeryapp <...> The support for this usage was removed in Celery 5.0. Instead you should use --app as a global option: celery --app celeryapp worker <...> Error: no such option: --app. I am not sure where i am doing wrong

The error message tells you what you need to change - the --app parameter has moved from being a parameter to celery worker to being a parameter to celery instead.

Your old command:

celery worker --app=worker.celery --loglevel=info

needs to be changed by moving --app to the left (so that it is a parameter to celery instead):

celery --app=worker.celery worker --loglevel=info
