  4. Introduction
  5. ------------
  6. Docker is an open-source engine to easily create lightweight, portable,
  7. self-sufficient containers from any application. The same container that a
  8. developer builds and tests on a laptop can run at scale, in production, on
  9. VMs, bare metal, OpenStack clusters, or any major infrastructure provider.
  10. Common use cases for Docker include:
  11. - Automating the packaging and deployment of web applications.
  12. - Automated testing and continuous integration/deployment.
  13. - Deploying and scaling databases and backend services in a service-oriented environment.
  14. - Building custom PaaS environments, either from scratch or as an extension of off-the-shelf platforms like OpenShift or Cloud Foundry.
  15. Please note Docker is currently under heavy developement. It should not be used in production (yet).
  16. For a high-level overview of Docker, please see the `Introduction
  17. <http://www.docker.io/learn_more/>`_. When you're ready to start working with
  18. Docker, we have a `quick start <http://www.docker.io/gettingstarted>`_
  19. and a more in-depth guide to :ref:`ubuntu_linux` and other
  20. :ref:`installation_list` paths including prebuilt binaries,
  21. Vagrant-created VMs, Rackspace and Amazon instances.
  22. Enough reading! :ref:`Try it out! <running_examples>`
