How docker volume container (mounted a host directory ) used in compose file version 2

In compose file version 1 , my docker-compose.yml is :

mongo:
    image: mongo
    volumes_from:
      -  mongodata
mongodata:
    image: mongo
    volumes:
       - /home/dbdata/mongodb:/data/db

In localhost "/home/dbdata/mongodb" ,i saved some data . And it can be read through mongo container .

But i don't know how to update to compose file version 2. I have updated docker and docker-compose to the latest.

Docker version 1.10.2, build c3959b1
docker-compose version 1.6.2, build 4d72027
OS: ubuntu 15.10

I tried three ways ,but not working.

one : the compose file is :

version: '2'
services:
  mongo:
    image: mongo
    volumes_from:
      -  mongodata
    networks:
      - wfij

  mongodata:
    image: mongo
    volumes:
       - /home/dbdata/mongodb:/data/db

 # this is a spring cloud service , it can read mongo user data
  useraccount:
    image: user-account
    networks:
      - wfij
networks:
  wfij:
    driver: bridge

But the spring user-account service can't read the mongo data .

Another method: the compose file

-

version: '2'
services:

  mongo:
    image: mongo
    volumes:
      -  mongo-data:/data/db
    networks:
      - wfij

  useraccount:
    image: user-account
    networks:
      - wfij


networks:
  wfij:
    driver: bridge
volumes:
  mongo-data:
    volumes: home/dbdata/mongodb

It not works again , the error is : "volumes is not supported" , but if i not set the volume container ,how can i mount the host directory "home/dbdata/mongodb" to the volume .

last , try this :

mongo:
    image: mongo
    volumes:
      -  mongo-data
voluems:
  - mongo-data: /home/keryhu/dbdata/mongodb:/data/db

The error is :

ERROR: In file './docker-compose.yml', volume 'mongo-data' must be a mapping not a string.

Can help me ?

version: '2'
services:
  mongo:
    image: mongo
    volumes_from:
      -  mongodata
  mongodata:
    image: mongo
    volumes:
       - /home/dbdata/mongodb:/data/db

This should work. You don't have to make any changes for host volumes. It's only important for named volumes.
