Introduction

------------

|

|
|
-``docker``, the Linux Container Runtime, runs Unix processes with
|
|
|
-strong guarantees of isolation across servers. Your software runs
|
|
|
-repeatably everywhere because its :ref:`container_def` includes any
|
|
|
-dependencies.
|
|
|
+Docker is an open-source engine 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, or any major infrastructure provider.
|
|
|
|
|
|
-``docker`` runs three ways:
|
|
|
+Common use cases for Docker include:
|
|
|
|
|
|
-* as a daemon to manage LXC containers on your host machine (``sudo docker -d``)
|
|
|
-* as a :ref:`CLI <cli>` which talks to the daemon's `REST API
|
|
|
- <api/docker_remote_api>`_ (``docker run ...``)
|
|
|
-* as a client of :ref:`Repositories <working_with_the_repository>`
|
|
|
- that let you share what you've built (``docker pull, docker
|
|
|
- commit``).

+- Automating the packaging and deployment of web applications.
|
|
|
+- Automated testing and continuous integration/deployment.
|
|
|
+- Deploying and scaling databases and backend services in a service-oriented environment.
|
|
|
+- Building custom PaaS environments, either from scratch or as an extension of off-the-shelf platforms like OpenShift or Cloud Foundry.

-Each use of ``docker`` is documented here. The features of Docker are
|
|
|
-currently in active development, so this documentation will change
|
|
|
-frequently.
|
|
|
+Please note Docker is currently under heavy developement. It should not be used in production (yet).
