使用docker-compose 启动失败 MongoError

[lidianhao123]

环境：

1. 操作系统: CentOS Linux release 7.2.1511 (Core)
2. docker: Docker version 18.03.0-ce, build 0520e24
3. docker-compose: docker-compose version 1.20.1, build 5d8c71b

描述

修改docker-compose.yml

开启 redis 和mongo 默认端口设置 6379 和 27017

     redis:
    image: redis:3.2-alpine
    command: redis-server --appendonly yes --requirepass egg_cnode
    volumes:
      - egg-redis:/data
    networks:
      - docker_cnode
    ports:
      - 6379:6379

  mongodb:
    image: mongo:3.2
    restart: always
    environment:
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=mongodb
      - MONGO_INITDB_DATABASE=egg_cnode
    volumes:
      - egg-mongo:/data/db
      - ./init.d/mongo:/docker-entrypoint-initdb.d
    networks:
      - docker_cnode
    ports:
      - 27017:27017

执行 docker-compose up -d 命令

[root@VM_0_11_centos egg-cnode]# docker-compose up -d
Creating network "eggcnode_docker_cnode" with driver "bridge"
Creating volume "eggcnode_egg-mongo" with default driver
Creating volume "eggcnode_egg-redis" with default driver

排查

链接mongodb数据库进行测试

[root@VM_0_11_centos egg-cnode]# mongo 172.19.0.2:27017/egg_cnode -u egg_cnode -p egg_cnode
MongoDB shell version: 3.2.19
connecting to: 172.19.0.2:27017/egg_cnode
> show collections
egg_cnode
> db.egg_cnode.find({})
{ "_id" : ObjectId("5ac9bfa4cdf6538a02662544"), "egg_cnode" : "egg-cnode" }

在centos 中可以正常访问 172.19.0.2:27017/egg_cnode 库

备注

本人 docker 和 docker-compose 知识有限，目前使用遇到如上问题，还望大神帮忙答疑解惑

Mac 本地一键拉起，暂未发现问题，明天用 CentOS 测试一下。
