Description: Docker: the open-source application container engine
 Docker is a product for you to build, ship and run any application as a
 lightweight container
 .
 Docker containers are both hardware-agnostic and platform-agnostic. This means
 they can run anywhere, from your laptop to the largest cloud compute instance and
 everything in between - and they don't require you to use a particular
 language, framework or packaging system. That makes them great building blocks
 for deploying and scaling web apps, databases, and backend services without
 depending on a particular stack or provider.

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
