python – Docker/Celery：无法运行芹菜

我不能让我的芹菜工人经常听默认队列.
芹菜不断退出.

$: docker-compose up

我正在尝试构建一个具有单独作业层的应用程序作为单独部署的作业容器.
所以架构是：

> EBS上的Web / App层(Django)
> Jobs Layer：Celery RabbitMQ作为Docker容器

这就是我所拥有的：

文件夹结构：

-tasker
    -tasker
        -tasks.py
        -celeryconfig.py
        - __init__.py
    -Dockerfile
    -docker-compose.yml
    -requirements.txt

tasks.py：

from celery import Celery
from celery import task

celery = Celery('tasks',broker='amqp://guest@localhost//')

import os


@celery.task
def add(x,y):
    return x + y

Dockerfile：

FROM python:3.4
ENV PYTHONBUFFERED 1
WORKDIR /tasker
ADD requirements.txt /tasker/
RUN pip install -r requirements.txt
ADD . /tasker/

泊坞窗,compose.yml：

rabbitmq:
  image: tutum/rabbitmq
  environment:
    - RABBITMQ_PASS=mypass
  ports:
    - "5672:5672"   
    - "15672:15672"
celery:
  build: .
  command: celery worker --app=tasker.tasks
  volumes:
    - .:/tasker
  links:
    - rabbitmq:rabbit

有什么我想念的吗？为什么芹菜退出代码1？
