# 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.
