我一直试图连接一个redis容器到我的节点应用程序容器，但我得到了以下错误。报告问题前请先解决。

docker-compose

version: "3"

services:
  vote:
    build: ./voting/.
    ports:
      - "3000:3000"
    networks:
      - front-tier
      - back-tier

  result:
    build: ./result/.
    ports:
      - "3011:3011"
    networks:
      - front-tier
      - back-tier

  worker:
    build:
      context: ./service_worker/.
    depends_on:
      - "redis"
      - "db"
    networks:
      - back-tier

  redis:
    image: redis:alpine
    container_name: redis
    ports: ["6379"]
    networks:
      - back-tier

  db:
    image: mongo:latest
    container_name: db
    networks:
      - back-tier

volumes:
  db-data:

networks:
  front-tier:
  back-tier:

在 docker-compose up ```

在 `docker logs redis` ```

当我尝试的时候 docker exec -ti redis redis-server ```
13:C 17 Oct 2020 07:42:16.608 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

现在我想这里有几个地方，我已经看到了redis配置文件的这个错误，但是如何在docker图像中解决它，这没有很好的解释。连接没有问题，但问题在于redis的conf。我可以用dns/ip从其他容器ping到那个容器。我认为，如果错误的最后一部分，其中*：6379不能听到，如果这和conf文件是编辑，应用程序将正常工作。
