docker-compose.yml for 1x MongoDB container plus 1x data volume container

I’m starting to dabble with docker-compose to link up some container goodness. If you’ve followed my other Docker related posts the past couple of days (here), then you might have noticed that I have something Raspberry Pi related cooking 🙂

Although I’ll have to redo these with a Pi compatible base images, to get MongoDB running in one container with a separate data volume container is actually pretty simple. Here’s what I ended up with. To start it up, ‘docker-compose up -d’ and you’re up and running (copy this to docker-compose.yml):

mongodata: 
 image: mongo:3.2
 volumes:
 - /data/db
 entrypoint: /bin/bash
mongo: 
 image: mongo:3.2
 volumes_from:
 - mongodata
 ports:
 - "27017:27017"
