Summary

Docker is an open-source engine that automates the deployment of any

application as a lightweight, portable, self-sufficient container that will

run virtually anywhere.

Docker containers can encapsulate any payload, and will run consistently on

and between virtually any server. The same container that a developer builds

and tests on a laptop will run at scale, in production*, on VMs, bare-metal

servers, OpenStack clusters, public instances, or combinations of the above.
