Redis SYNC 套接字上的错误情况：连接被拒绝

在我的 django 应用程序中使用 celery 和 redis 一切都工作正常，直到我遇到了问题。 redis 文件的位置已更改，redis 无法访问它们。经过查找，原来这是由于网络随机攻击造成的，需要添加confg 我添加文件后，一段时间都工作得很好，然后就出现了这个问题

当我重建 Redis 容器时，它运行了很短的时间，并且遇到了同样的问题

设置.py

CELERY_BROKER_URL = os.environ.get("redis://redis:6379/0")
CELERY_RESULT_BACKEND = os.environ.get("redis://redis:6379/0")

docker-compose.yml

     redis:
      image: 'redis:alpine'
      restart: unless-stopped
      command: redis-server /usr/local/etc/redis/redis.conf
      volumes:
        - ./docker/redis/redis.conf:/usr/local/etc/redis/redis.conf
      ports:
        - '6379:6379'


  celery:
    restart: unless-stopped
    build:
      context: .
      dockerfile: ./docker/backend/Dockerfile_celery
    entrypoint: /app/docker/backend/celery-entrypoint.sh
    environment:
      - some env vars
    depends_on:
      - asgiserver
      - redis

redis.conf

    bind 0.0.0.0 
    protected-mode yes
    rename-command CONFIG ""

通过改变解决ports配置为expose as 伊恩谢尔文顿上文提到的

   redis:
      image: 'redis:alpine'
      restart: unless-stopped
      command: redis-server /usr/local/etc/redis/redis.conf
      volumes:
        - ./docker/redis/redis.conf:/usr/local/etc/redis/redis.conf
      expose:
        - 6379
