A docker is an application (and its dependencies) wrapped in a container - it runs on top of the docker engine on a host.  The docker engine is specific to the host operating system, but the container is OS-independent, so can run on a docker engine running on any host.  It is a lightweight way of insulating an application from the OS and the OS from the application.  Other virtualization systems include the complete OS to run whatever applications you have, so a host server running mulitple VMs must run several independent OSes.  With the same set of applications on Docker, the system runs a single OS (the host machine's OS), and via a fairly thin interface runs multiple applications, each in their own docker.

See docker.com for more details.
