不确定如何为 Celery 指定应用程序

Question

以下是我的应用程序的结构：

- anp_tasks
  - __init__.py
  - celery.py
  - tasks.py
- platform
  - webapp
    - app
      [entire django project]
    - manage.py
  - Dockerfile
  - requirements.txt
- docker-compose.yml

Dockerfile 内容

FROM python:latest
LABEL maintainer="Akrogoniaios Technologies Corp."

ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt

RUN pip install --upgrade pip
RUN ln -s /usr/bin/pip3 /usr/bin/pip

RUN apt-get update && apt-get install -y gcc libjpeg-dev libc-dev musl-dev zlib1g zlib1g-dev apt-utils

RUN pip install -r ./requirements.txt

#copy the app files and proceed

RUN mkdir /app
WORKDIR /app
COPY ./webapp /app

RUN mkdir -p /vol/web/media
RUN mkdir -p /vol/web/static

要求.txt

Django>=3.1
djangorestframework>=3.12
psycopg2==2.8.3
celery>=5.0.2

anp_tasks 中的init .py

from __future__ import absolute_import, unicode_literals

__all__ = ['anp_tasks']

celery.py 的内容

from celery import Celery

app = Celery('anp_tasks',
         broker='amqp://',
         backend='rpc://',
         include=['anp_tasks.tasks'])

app.conf.update(
    result_expires=3600,
)

if __name__ == '__main__':
    app.start()

* anp_tasks里面tasks.py的内容

from .celery import app

@app.task
def print_hello():
    print ("hello there")

特定于芹菜的 docker-compose.yml 的内容

broker:
    image: rabbitmq:latest
env_file:
    - ./platform/anp_rabbitmq.env
volumes:
    - "./rabbitmq:/data"

worker:
    build:
        context: ./platform
command: "celery -A .\anp_tasks worker -l INFO "
environment:
    - DEBUG=1
depends_on:
    - broker

但是，当我运行 docker-compose up 时，它会引发以下错误。

worker_1    | Usage: celery [OPTIONS] COMMAND [ARGS]...
worker_1    | 
worker_1    | Error: Invalid value for '-A' / '--app':

如何指定芹菜的应用程序路径？
