使用docker进行部署时,Celery,Django,Redis遇到错误99

我尝试在docker中部署我的Django项目和芹菜,我想使用redis作为后端的结果.

Django版本1.11.3
芹菜版4.1.0

我的docker-compose.yml如下：

python:
  image: python:latest
  restart: always
  expose:
    - "8000"
  volumes:
    - ~/django/902Scratch/API:/home/django/API 
    - /var/sb2_files:/var/sb2_files 
    - /home/tuopinpin/JudgeServer/tests/test_case:/test_case 
  links:
    - celery:celery
  command: bash -c " cd /home/django/API &&  python manage.py runserver 0.0.0.0:8000"
  ports:
        - "0.0.0.0:8000:8000"

celery:
  image: python:latest
  restart: always
  volumes:
    - ~/django/902Scratch/API:/home/django/API 
    - /var/sb2_files:/var/sb2_files 
  user: nobody
  depends_on:
    - redis
  links:
    - redis:redis
  command: bash -c " cd /home/django/API && celery -A API worker"

redis:
  image: redis:alpine
  restart: always
  expose:
    - '6379'
  ports:
    - '6379:6379'

django的芹菜设置如下：

CELERY_BROKER_URL = 'redis://redis:6379/0'
CELERY_BROKER_TRANSPORT = 'redis'
CELERY_RESULT_BACKEND = "redis"
CELERY_BACKEND_URL = 'redis://redis:6379/1'

和celery -A proj report命令返回这样的信息

我很困惑,因为我已将CELERY_BACKEND_URL修改为redis：// redis：6379/0. redis是docker-compose中的主机名,但似乎芹菜正在尝试连接到localhost.我尝试在没有docker的情况下部署所有这些,并将CELERY_BACKEND_URL修改回127.0.0.1,一切正常.我还尝试使用python docker和celery docker上的python redis库连接到redis,并且两个docker都可以使用redis.


最佳答案
我会尝试将它们设置在同一个docker网络中,然后检查它们是否可以看到对方,在运行你的docker-compose之后尝试一个docker exec -it celery curl redis：6379
你可以检查的另一件事是docker exec -it redis curl localhost：6379 with / 0和/ 1然后如果一切正常,在这个检查中它可能是一个conf问题,否则很可能你的redis启动不正确或你的容器没有看到对方,然后你需要调查一下,但首先要检查的是你的所有服务都正常运行,你的容器可以看到对方

使用docker进行部署时,Celery,Django,Redis遇到错误99
