        image: mongo
        volumes:
            - /home/DockerCompose/lottery/mongo/db:/data/db   # /data/db是container中存放数据位置

        image: mongo-express
        restart: always
        depends_on:

    redis:
        container_name: redis

        restart: on-failure
        volumes:
            - /home/DockerCompose/lottery/redis/conf/redis.conf:/usr/local/etc/redis/redis.conf
            - /home/DockerCompose/lottery/redis/db/:/data/
        networks: 
            - my-server
networks:
    my-server:

  config.mongoose = {
    client: {
      url: config.env === 'dev' ?'mongodb://localhost:27017/lottery': 'mongodb://mongo:27017/lottery_dev', // user是collection(数据库)名称
      // url: config.env === 'dev' ?'mongodb://admin:junmoxiao1122@101.133.170.51:27017/lottery_dev': 'mongodb://admin:junmoxiao1122@101.133.170.51:27017/lottery_dev', // user是collection(数据库)名称
      options: {
        useUnifiedTopology: true   
      }, // 其他配置项
    },
  };

我想要达到的结果

egg可以连接服务器上的mongodb 而不是docekr内的
