Hello World
===========

.. include:: example_header.inc

This is the most basic example available for using Docker.

Download the base container

.. code-block:: bash

    # Download a base image
    docker pull base

The *base* image is a minimal *ubuntu* based container, alternatively you can select *busybox*, a bare
minimal linux system. The images are retrieved from the docker repository.


.. code-block:: bash

    #run a simple echo command, that will echo hello world back to the console over standard out.
    docker run base /bin/echo hello world

**Explanation:**

- **"docker run"** run a command in a new container 
- **"base"** is the image we want to run the command inside of.
- **"/bin/echo"** is the command we want to run in the container
- **"hello world"** is the input for the echo command
