| # 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. |
