Celery Worker无法连接Redis容器问题排查求助

问题情况 #

我已经完成FastAPI + Celery Worker + Redis应用的Docker容器化部署，但遇到容器间Redis连接失败的问题。本地直接运行（uvicorn启动API、Celery Worker独立进程、Redis实例）时完全正常，容器内却无法建立连接。

错误信息 #

使用docker-compose启动Worker时，出现如下错误：

worker | TypeError: Channel._connparams..Connection.disconnect() takes 1 positional argument but 2 were given

相关配置 #

docker-compose.yml #

services:
  app:
    build:
      context: app
    container_name: app
    working_dir: /code
    command: pipenv run uvicorn src.app:app --host 0.0.0.0 --port 8000 --reload
    volumes:
      - "./app:/code/"
    ports:
      - "8000:8000"
    depends_on:
      - redis
    links:
      - redis
    networks:
      - local

  worker:
    build:
      context: app
    container_name: worker
    command: pipenv run celery -A src.worker.celery worker --loglevel=info
    volumes:
      - "./app:/code/"
    depends_on:
      - redis
    links:
      - redis
    networks:
      - local

  redis:
    container_name: redis
    hostname: redis
    image: redis:7.0.9-alpine
    networks:
      - local

networks:
  local:
    name: local

Celery Worker配置 #

celery = Celery(__name__)
celery.conf.broker_url = "redis://redis:6379"
celery.conf.result_backend = "redis://redis:6379"

额外测试 #

我在其他容器中运行以下简单的Redis连接测试代码，结果仅出现超时：

from redis import Redis

redis_hostname = "redis"
r = Redis(redis_hostname, socket_connect_timeout=1)
r.ping()

请问我的配置哪里可能存在问题？
