Docker manages [Dockerhub](https://hub.docker.com), a central repository where people can upload Docker images to share to the wider community.

We're going to grab an image from Dockerhub and use it for some examples. A very basic image available on Dockerhub is the Ubuntu image, which provides a bare-bones Ubuntu environment.
