## Volumes
Docker volumes are [free-floating filesystems](http://docs.docker.com/userguide/dockervolumes/). They don't have to be connected to a particular container. You should use [use volumes mounted from data-only containers](https://medium.com/@ramangupta/why-docker-data-containers-are-good-589b3c6c749e) for portability.

Volumes are useful in situations where you can't use links (which are TCP/IP only). For instance, if you need to have two docker instances communicate by leaving stuff on the filesystem.
