-# Short-Description:  Create lightweight, portable, self-sufficient containers.
-# Description:
-#  Docker is an open-source project to easily create lightweight, portable,
-#  self-sufficient containers from any application. The same container that a
-#  developer builds and tests on a laptop can run at scale, in production, on
-#  VMs, bare metal, OpenStack clusters, public clouds and more.
