mongodb - 无法连接到mongodb容器

Question

我无法连接到使用 docker-compose 创建的 mongodb 容器

mongodb 配置(在 docker-compose.yml 中)如下:

mongodata:
  image: mongo:3.0.4
  volumes:
    - /data/db
  command: --break-mongo

mongo:
  image: mongo:3.0.4
  volumes_from:
    - mongodata
  ports:
    - "27017:27017"
  command: --smallfiles --rest --auth

当我运行时:

docker-compose ps mongo

我有:

      Name                    Command               State            Ports
------------------------------------------------------------------------------------
followit_mongo_1   /entrypoint.sh --smallfile ...   Up      0.0.0.0:27017->27017/tcp

我无法连接mongo客户端，下面的命令

docker-compose run mongo mongo

失败，这是错误:

MongoDB shell version: 3.0.4

Answer 1

尝试使用 -p 选项将 27017 容器的端口发布到主机

docker-compose run -p 27017:27017 mongo mongo

我可以通过这种方式从主机访问 mongo。
