+# Contributing to Docker
+
+Want to hack on Docker? Awesome! Here are instructions to get you started. They are probably not perfect, please let us know if anything feels
+wrong or incomplete.
+
+## Contribution guidelines
+
+### Pull requests are always welcome
+
+We are always thrilled to receive pull requests, and do our best to
+process them as fast as possible. Not sure if that typo is worth a pull
+request? Do it! We will appreciate it.
+
+If your pull request is not accepted on the first try, don't be
+discouraged! If there's a problem with the implementation, hopefully you
+received feedback on what to improve.
+
+We're trying very hard to keep Docker lean and focused. We don't want it
+to do everything for everybody. This means that we might decide against
+incorporating a new feature. However, there might be a way to implement
+that feature *on top of* docker.
+
+### Discuss your design on the mailing list
+
+We recommend discussing your plans [on the mailing
+list](https://groups.google.com/forum/?fromgroups#!forum/docker-club)
+before starting to code - especially for more ambitious contributions.
+This gives other contributors a chance to point you in the right
+direction, give feedback on your design, and maybe point out if someone
+else is working on the same thing.
+
+### Create issues...
+
+Any significant improvement should be documented as [a github
+issue](https://github.com/dotcloud/docker/issues) before anybody
+starts working on it.
+
+### ...but check for existing issues first!
+
+Please take a moment to check that an issue doesn't already exist
+documenting your bug report or improvement proposal. If it does, it
+never hurts to add a quick "+1" or "I have this problem too". This will
+help prioritize the most common problems and requests.
+
+### Conventions
+
+Fork the repo and make changes on your fork in a feature branch:
+
+- If it's a bugfix branch, name it XXX-something where XXX is the number of the
+  issue
+- If it's a feature branch, create an enhancement issue to announce your
+  intentions, and name it XXX-something where XXX is the number of the issue.
+
+Submit unit tests for your changes.  Go has a great test framework built in; use
+it! Take a look at existing tests for inspiration. Run the full test suite on
+your branch before submitting a pull request.
+
+Make sure you include relevant updates or additions to documentation when
+creating or modifying features.
+
+Write clean code. Universally formatted code promotes ease of writing, reading,
+and maintenance. Always run `go fmt` before committing your changes. Most
+editors have plugins that do this automatically, and there's also a git
+pre-commit hook:
+
+```
+curl -o .git/hooks/pre-commit https://raw.github.com/edsrzf/gofmt-git-hook/master/fmt-check && chmod +x .git/hooks/pre-commit
+```
+
+Pull requests descriptions should be as clear as possible and include a
+reference to all the issues that they address.
+
+Code review comments may be added to your pull request. Discuss, then make the
+suggested modifications and push additional commits to your feature branch. Be
+sure to post a comment after pushing. The new commits will show up in the pull
+request automatically, but the reviewers will not be notified unless you
+comment.
+
+Before the pull request is merged, make sure that you squash your commits into
+logical units of work using `git rebase -i` and `git push -f`. After every
+commit the test suite should be passing. Include documentation changes in the
+same commit so that a revert would remove all traces of the feature or fix.
+
+Commits that fix or close an issue should include a reference like `Closes #XXX`
+or `Fixes #XXX`, which will automatically close the issue when merged.
+
+Add your name to the AUTHORS file, but make sure the list is sorted and your
+name and email address match your git configuration. The AUTHORS file is
+regenerated occasionally from the git commit history, so a mismatch may result
+in your changes being overwritten.
+
+
+## Decision process
+
+### How are decisions made?
+
+Short answer: with pull requests to the docker repository.
+
+Docker is an open-source project with an open design philosophy. This means that the repository is the source of truth for EVERY aspect of the project,
+including its philosophy, design, roadmap and APIs. *If it's part of the project, it's in the repo. It's in the repo, it's part of the project.*
+
+As a result, all decisions can be expressed as changes to the repository. An implementation change is a change to the source code. An API change is a change to
+the API specification. A philosophy change is a change to the philosophy manifesto. And so on.
+
+All decisions affecting docker, big and small, follow the same 3 steps:
+
+* Step 1: Open a pull request. Anyone can do this.
+
+* Step 2: Discuss the pull request. Anyone can do this.
+
+* Step 3: Accept or refuse a pull request. The relevant maintainer does this (see below "Who decides what?")
+
+
+### Who decides what?
+
+So all decisions are pull requests, and the relevant maintainer makes the decision by accepting or refusing the pull request.
+But how do we identify the relevant maintainer for a given pull request?
+
+Docker follows the timeless, highly efficient and totally unfair system known as [Benevolent dictator for life](http://en.wikipedia.org/wiki/Benevolent_Dictator_for_Life),
+with yours truly, Solomon Hykes, in the role of BDFL.
+This means that all decisions are made by default by me. Since making every decision myself would be highly unscalable, in practice decisions are spread across multiple maintainers.
+
+The relevant maintainer for a pull request is assigned in 3 steps:
+
+* Step 1: Determine the subdirectory affected by the pull request. This might be src/registry, docs/source/api, or any other part of the repo.
+
+* Step 2: Find the MAINTAINERS file which affects this directory. If the directory itself does not have a MAINTAINERS file, work your way up the the repo hierarchy until you find one.
+
+* Step 3: The first maintainer listed is the primary maintainer. The pull request is assigned to him. He may assign it to other listed maintainers, at his discretion.
+
+
+### I'm a maintainer, should I make pull requests too?
+
+Primary maintainers are not required to create pull requests when changing their own subdirectory, but secondary maintainers are.
+
+### Who assigns maintainers?
+
+Solomon.
+
+### How can I become a maintainer?
+
+* Step 1: learn the component inside out
+* Step 2: make yourself useful by contributing code, bugfixes, support etc.
+* Step 3: volunteer on the irc channel (#docker@freenode)
+
+Don't forget: being a maintainer is a time investment. Make sure you will have time to make yourself available.
+You don't have to be a maintainer to make a difference on the project!
+
+### What are a maintainer's responsibility?
+
+It is every maintainer's responsibility to:
+
+* 1) Expose a clear roadmap for improving their component.
+* 2) Deliver prompt feedback and decisions on pull requests.
+* 3) Be available to anyone with questions, bug reports, criticism etc. on their component. This includes irc, github requests and the mailing list.
+* 4) Make sure their component respects the philosophy, design and roadmap of the project.
+
+### How is this process changed?
+
+Just like everything else: by making a pull request :)

-Docker is a process manager with superpowers
-============================================
+Docker: the Linux container engine
+==================================
 
-It encapsulates heterogeneous payloads in Standard Containers, and runs them on any server with strong guarantees of isolation and repeatability.
+Docker is an open-source engine which automates the deployment of applications as highly portable, self-sufficient containers.
 
-Is is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.
+Docker containers are both *hardware-agnostic* and *platform-agnostic*. This means that they can run anywhere, from your
+laptop to the largest EC2 compute instance and everything in between - and they don't require that you 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.
 
-<img src="http://bricks.argz.com/bricksfiles/lego/07000/7823/012.jpg"/>
+Docker is an open-source implementation of the deployment engine which powers [dotCloud](http://dotcloud.com), a popular Platform-as-a-Service.
+It benefits directly from the experience accumulated over several years of large-scale operation and support of hundreds of thousands
+of applications and databases.
 
-* *Heterogeneous payloads*: any combination of binaries, libraries, configuration files, scripts, virtualenvs, jars, gems, tarballs, you name it. No more juggling between domain-specific tools. Docker can deploy and run them all.
+![Docker L](docs/sources/concepts/images/lego_docker.jpg "Docker")
 
-* *Any server*: docker can run on any x64 machine with a modern linux kernel - whether it's a laptop, a bare metal server or a VM. This makes it perfect for multi-cloud deployments.
+## Better than VMs
 
-* *Isolation*: docker isolates processes from each other and from the underlying host, using lightweight containers. 
+A common method for distributing applications and sandbox their execution is to use virtual machines, or VMs. Typical VM formats
+are VMWare's vmdk, Oracle Virtualbox's vdi, and Amazon EC2's ami. In theory these formats should allow every developer to
+automatically package their application into a "machine" for easy distribution and deployment. In practice, that almost never
+happens, for a few reasons:
 
-* *Repeatability*: because containers are isolated in their own filesystem, they behave the same regardless of where, when, and alongside what they run.
+  * *Size*: VMs are very large which makes them impractical to store and transfer.
+  * *Performance*: running VMs consumes significant CPU and memory, which makes them impractical in many scenarios, for example local development of multi-tier applications, and
+  	large-scale deployment of cpu and memory-intensive applications on large numbers of machines.
+  * *Portability*: competing VM environments don't play well with each other. Although conversion tools do exist, they are limited and add even more overhead.
+  * *Hardware-centric*: VMs were designed with machine operators in mind, not software developers. As a result, they offer very limited tooling for what developers need most:
+  	building, testing and running their software. For example, VMs offer no facilities for application versioning, monitoring, configuration, logging or service discovery.
+
+By contrast, Docker relies on a different sandboxing method known as *containerization*. Unlike traditional virtualization,
+containerization takes place at the kernel level. Most modern operating system kernels now support the primitives necessary
+for containerization, including Linux with [openvz](http://openvz.org), [vserver](http://linux-vserver.org) and more recently [lxc](http://lxc.sourceforge.net),

+
+Docker builds on top of these low-level primitives to offer developers a portable format and runtime environment that solves
+all 4 problems. Docker containers are small (and their transfer can be optimized with layers), they have basically zero memory and cpu overhead,
+they are completely portable and are designed from the ground up with an application-centric design.
+
+The best part: because docker operates at the OS level, it can still be run inside a VM!
+
+## Plays well with others
+
+Docker does not require that you buy into a particular programming language, framework, packaging system or configuration language.
+
+Is your application a unix process? Does it use files, tcp connections, environment variables, standard unix streams and command-line
+arguments as inputs and outputs? Then docker can run it.
+
+Can your application's build be expressed as a sequence of such commands? Then docker can build it.
 
 
-Notable features
------------------
+## Escape dependency hell
 
-* Filesystem isolation: each process container runs in a completely separate root filesystem.
+A common problem for developers is the difficulty of managing all their application's dependencies in a simple and automated way.
 
-* Resource isolation: system resources like cpu and memory can be allocated differently to each process container, using cgroups.
+This is usually difficult for several reasons:
 
-* Network isolation: each process container runs in its own network namespace, with a virtual interface and IP address of its own.
+  * *Cross-platform dependencies*. Modern applications often depend on a combination of system libraries and binaries, language-specific packages, framework-specific modules,
+  	internal components developed for another project, etc. These dependencies live in different "worlds" and require different tools - these tools typically don't work
+	well with each other, requiring awkward custom integrations.
 
-* Copy-on-write: root filesystems are created using copy-on-write, which makes deployment extremeley fast, memory-cheap and disk-cheap.
-
-* Logging: the standard streams (stdout/stderr/stdin) of each process container is collected and logged for real-time or batch retrieval.
-
-* Change management: changes to a container's filesystem can be committed into a new image and re-used to create more containers. No templating or manual configuration required.
-
-* Interactive shell: docker can allocate a pseudo-tty and attach to the standard input of any container, for example to run a throaway interactive shell.
+  * Conflicting dependencies. Different applications may depend on different versions of the same dependency. Packaging tools handle these situations with various degrees of ease -
+  	but they all handle them in different and incompatible ways, which again forces the developer to do extra work.
+  
+  * Custom dependencies. A developer may need to prepare a custom version of his application's dependency. Some packaging systems can handle custom versions of a dependency,
+  	others can't - and all of them handle it differently.
 
 
+Docker solves dependency hell by giving the developer a simple way to express *all* his application's dependencies in one place,
+and streamline the process of assembling them. If this makes you think of [XKCD 927](http://xkcd.com/927/), don't worry. Docker doesn't
+*replace* your favorite packaging systems. It simply orchestrates their use in a simple and repeatable way. How does it do that? With layers.
+
+Docker defines a build as running a sequence of unix commands, one after the other, in the same container. Build commands modify the contents of the container
+(usually by installing new files on the filesystem), the next command modifies it some more, etc. Since each build command inherits the result of the previous
+commands, the *order* in which the commands are executed expresses *dependencies*.
+
+Here's a typical docker build process:
+
+```bash
+from ubuntu:12.10
+run apt-get update
+run DEBIAN_FRONTEND=noninteractive apt-get install -q -y python
+run DEBIAN_FRONTEND=noninteractive apt-get install -q -y python-pip
+run pip install django
+run DEBIAN_FRONTEND=noninteractive apt-get install -q -y curl
+run curl -L https://github.com/shykes/helloflask/archive/master.tar.gz | tar -xzv
+run cd helloflask-master && pip install -r requirements.txt
+```
+
+Note that Docker doesn't care *how* dependencies are built - as long as they can be built by running a unix command in a container.
+
+
+Install instructions
+==================
+
+Quick install on Ubuntu 12.04 and 12.10
+---------------------------------------
+
+```bash
+curl get.docker.io | sh -x
+```
+
+Binary installs
+----------------
+
+Docker supports the following binary installation methods.
+Note that some methods are community contributions and not yet officially supported.
+
+* [Ubuntu 12.04 and 12.10 (officially supported)](http://docs.docker.io/en/latest/installation/ubuntulinux/)
+* [Arch Linux](http://docs.docker.io/en/latest/installation/archlinux/)
+* [MacOS X (with Vagrant)](http://docs.docker.io/en/latest/installation/macos/)
+* [Windows (with Vagrant)](http://docs.docker.io/en/latest/installation/windows/)
+* [Amazon EC2 (with Vagrant)](http://docs.docker.io/en/latest/installation/amazon/)
+
+Installing from source
+----------------------
+
+1. Make sure you have a [Go language](http://golang.org/doc/install) compiler and [git](http://git-scm.com) installed.
+
+2. Checkout the source code
+
+   ```bash
+   git clone http://github.com/dotcloud/docker
+   ```
+
+3. Build the docker binary
+
+   ```bash
+   cd docker
+   make VERBOSE=1
+   sudo cp ./bin/docker /usr/local/bin/docker
+   ```
+
+Usage examples
+==============
+
+First run the docker daemon
+---------------------------
+
+All the examples assume your machine is running the docker daemon. To run the docker daemon in the background, simply type:
+
+```bash
+# On a production system you want this running in an init script
+sudo docker -d &
+```
+
+Now you can run docker in client mode: all commands will be forwarded to the docker daemon, so the client can run from any account.
+
+```bash
+# Now you can run docker commands from any account.
+docker help
+```
+
+
+Throwaway shell in a base ubuntu image
+--------------------------------------
+
+```bash
+docker pull ubuntu:12.10
+
+# Run an interactive shell, allocate a tty, attach stdin and stdout
+# To detach the tty without exiting the shell, use the escape sequence Ctrl-p + Ctrl-q
+docker run -i -t ubuntu:12.10 /bin/bash
+```
+
+Starting a long-running worker process
+--------------------------------------
+
+```bash
+# Start a very useful long-running process
+JOB=$(docker run -d ubuntu /bin/sh -c "while true; do echo Hello world; sleep 1; done")
+
+# Collect the output of the job so far
+docker logs $JOB
+
+# Kill the job
+docker kill $JOB
+```
+
+Running an irc bouncer
+----------------------
+
+```bash
+BOUNCER_ID=$(docker run -d -p 6667 -u irc shykes/znc $USER $PASSWORD)
+echo "Configure your irc client to connect to port $(docker port $BOUNCER_ID 6667) of this machine"
+```
+
+Running Redis
+-------------
+
+```bash
+REDIS_ID=$(docker run -d -p 6379 shykes/redis redis-server)
+echo "Configure your redis client to connect to port $(docker port $REDIS_ID 6379) of this machine"
+```
+
+Share your own image!
+---------------------
+
+```bash
+CONTAINER=$(docker run -d ubuntu:12.10 apt-get install -y curl)
+docker commit -m "Installed curl" $CONTAINER $USER/betterbase
+docker push $USER/betterbase
+```
+
+A list of publicly available images is [available here](https://github.com/dotcloud/docker/wiki/Public-docker-images).
+
+Expose a service on a TCP port
+------------------------------
+
+```bash
+# Expose port 4444 of this container, and tell netcat to listen on it
+JOB=$(docker run -d -p 4444 base /bin/nc -l -p 4444)
+
+# Which public port is NATed to my container?
+PORT=$(docker port $JOB 4444)
+
+# Connect to the public port via the host's public address
+# Please note that because of how routing works connecting to localhost or 127.0.0.1 $PORT will not work.
+IP=$(ifconfig eth0 | perl -n -e 'if (m/inet addr:([\d\.]+)/g) { print $1 }')
+echo hello world | nc $IP $PORT
+
+# Verify that the network connection worked
+echo "Daemon received: $(docker logs $JOB)"
+```

 What is a Standard Container?
------------------------------
+=============================
 
 Docker defines a unit of software delivery called a Standard Container. The goal of a Standard Container is to encapsulate a software component and all its dependencies in
-a format that is self-describing and portable, so that any compliant runtime can run it without extra dependency, regardless of the underlying machine and the contents of the container.

-The spec for Standard Containers is currently work in progress, but it is very straightforward. It mostly defines 1) an image format, 2) a set of standard operations, and 3) an execution environment.

+# docker-build: build your software with docker
+
+## Description
+
+docker-build is a script to build docker images from source. It will be deprecated once the 'build' feature is incorporated into docker itself (See https://github.com/dotcloud/docker/issues/278)
+
+Author: Solomon Hykes <solomon@dotcloud.com>
+
+
+## Install
+
+docker-builder requires:
+
+1) A reasonably recent Python setup (tested on 2.7.2).
+
+2) A running docker daemon at version 0.1.4 or more recent (http://www.docker.io/gettingstarted)
+
+
+## Usage
+
+First create a valid Changefile, which defines a sequence of changes to apply to a base image.
+
+    $ cat Changefile
+    # Start build from a know base image
+    from	base:ubuntu-12.10
+    # Update ubuntu sources
+    run	echo 'deb http://archive.ubuntu.com/ubuntu quantal main universe multiverse' > /etc/apt/sources.list
+    run	apt-get update
+    # Install system packages
+    run	DEBIAN_FRONTEND=noninteractive apt-get install -y -q git
+    run DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl
+    run DEBIAN_FRONTEND=noninteractive apt-get install -y -q golang
+    # Insert files from the host (./myscript must be present in the current directory)
+    copy	myscript /usr/local/bin/myscript
+
+
+Run docker-build, and pass the contents of your Changefile as standard input.
+
+    $ IMG=$(./docker-build < Changefile)
+
+This will take a while: for each line of the changefile, docker-build will:
+
+1. Create a new container to execute the given command or insert the given file
+2. Wait for the container to complete execution
+3. Commit the resulting changes as a new image
+4. Use the resulting image as the input of the next step
+
+
+If all the steps succeed, the result will be an image containing the combined results of each build step.
+You can trace back those build steps by inspecting the image's history:
+
+    $ docker history $IMG
+    ID                  CREATED             CREATED BY
+    1e9e2045de86        A few seconds ago   /bin/sh -c cat > /usr/local/bin/myscript; chmod +x /usr/local/bin/git
+    77db140aa62a        A few seconds ago   /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q golang
+    77db140aa62a        A few seconds ago   /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q curl
+    77db140aa62a        A few seconds ago   /bin/sh -c DEBIAN_FRONTEND=noninteractive apt-get install -y -q git 
+    83e85d155451        A few seconds ago   /bin/sh -c apt-get update
+    bfd53b36d9d3        A few seconds ago   /bin/sh -c echo 'deb http://archive.ubuntu.com/ubuntu quantal main universe multiverse' > /etc/apt/sources.list
+    base		2 weeks ago         /bin/bash
+    27cf78414709        2 weeks ago
+
+
+Note that your build started from 'base', as instructed by your Changefile. But that base image itself seems to have been built in 2 steps - hence the extra step in the history.
+
+
+You can use this build technique to create any image you want: a database, a web application, or anything else that can be build by a sequence of unix commands - in other words, anything else.

+Docker documentation and website
+================================
+
+Documentation
+-------------
+This is your definite place to contribute to the docker documentation. The documentation is generated from the
+.rst files under sources.
+
+The folder also contains the other files to create the http://docker.io website, but you can generally ignore
+most of those.
+
+
+Installation
+------------
+
+* Work in your own fork of the code, we accept pull requests.
+* Install sphinx: `pip install sphinx`
+    * Mac OS X: `[sudo] pip-2.7 install sphinx`)
+* Install sphinx httpdomain contrib package: `pip install sphinxcontrib-httpdomain`
+    * Mac OS X: `[sudo] pip-2.7 install sphinxcontrib-httpdomain`
+* If pip is not available you can probably install it using your favorite package manager as **python-pip**
+
+Usage
+-----
+* Change the `.rst` files with your favorite editor to your liking.
+* Run `make docs` to clean up old files and generate new ones.
+* Your static website can now be found in the `_build` directory.
+* To preview what you have generated run `make server` and open <http://localhost:8000/> in your favorite browser.
+
+Working using GitHub's file editor
+----------------------------------
+Alternatively, for small changes and typo's you might want to use GitHub's built in file editor. It allows
+you to preview your changes right online. Just be carefull not to create many commits.
+
+Images
+------
+When you need to add images, try to make them as small as possible (e.g. as gif).
+
+
+Notes
+-----
+* The index.html and gettingstarted.html files are copied from the source dir to the output dir without modification.
+So changes to those pages should be made directly in html
+* For the template the css is compiled from less. When changes are needed they can be compiled using
+lessc ``lessc main.less`` or watched using watch-lessc ``watch-lessc -i main.less -o main.css``
+
+
+Guides on using sphinx
+----------------------
+* To make links to certain pages create a link target like so:
+
+  ```
+    .. _hello_world:
+
+    Hello world
+    ===========
+
+    This is.. (etc.)
+  ```
+
+  The ``_hello_world:`` will make it possible to link to this position (page and marker) from all other pages.
+
+* Notes, warnings and alarms
+
+  ```
+    # a note (use when something is important)
+    .. note::
+
+    # a warning (orange)
+    .. warning::
+
+    # danger (red, use sparsely)
+    .. danger::
+
+* Code examples
+
+  Start without $, so it's easy to copy and paste.

+
+===================
+Docker Registry API
+===================
+
+.. contents:: Table of Contents
+
+1. The 3 roles
+===============
+
+1.1 Index
+---------
+
+The Index is responsible for centralizing information about:
+- User accounts
+- Checksums of the images
+- Public namespaces
+
+The Index has different components:
+- Web UI
+- Meta-data store (comments, stars, list public repositories)
+- Authentication service
+- Tokenization
+
+The index is authoritative for those information.
+
+We expect that there will be only one instance of the index, run and managed by dotCloud.
+
+1.2 Registry
+------------
+- It stores the images and the graph for a set of repositories
+- It does not have user accounts data
+- It has no notion of user accounts or authorization
+- It delegates authentication and authorization to the Index Auth service using tokens
+- It supports different storage backends (S3, cloud files, local FS)
+- It doesn’t have a local database
+- It will be open-sourced at some point
+
+We expect that there will be multiple registries out there. To help to grasp the context, here are some examples of registries:
+
+- **sponsor registry**: such a registry is provided by a third-party hosting infrastructure as a convenience for their customers and the docker community as a whole. Its costs are supported by the third party, but the management and operation of the registry are supported by dotCloud. It features read/write access, and delegates authentication and authorization to the Index.
+- **mirror registry**: such a registry is provided by a third-party hosting infrastructure but is targeted at their customers only. Some mechanism (unspecified to date) ensures that public images are pulled from a sponsor registry to the mirror registry, to make sure that the customers of the third-party provider can “docker pull” those images locally.
+- **vendor registry**: such a registry is provided by a software vendor, who wants to distribute docker images. It would be operated and managed by the vendor. Only users authorized by the vendor would be able to get write access. Some images would be public (accessible for anyone), others private (accessible only for authorized users). Authentication and authorization would be delegated to the Index. The goal of vendor registries is to let someone do “docker pull basho/riak1.3” and automatically push from the vendor registry (instead of a sponsor registry); i.e. get all the convenience of a sponsor registry, while retaining control on the asset distribution.
+- **private registry**: such a registry is located behind a firewall, or protected by an additional security layer (HTTP authorization, SSL client-side certificates, IP address authorization...). The registry is operated by a private entity, outside of dotCloud’s control. It can optionally delegate additional authorization to the Index, but it is not mandatory.
+
+.. note::
+
+    Mirror registries and private registries which do not use the Index don’t even need to run the registry code. They can be implemented by any kind of transport implementing HTTP GET and PUT. Read-only registries can be powered by a simple static HTTP server.
+
+.. note::
+
+    The latter implies that while HTTP is the protocol of choice for a registry, multiple schemes are possible (and in some cases, trivial):
+        - HTTP with GET (and PUT for read-write registries);
+        - local mount point;
+        - remote docker addressed through SSH.
+
+The latter would only require two new commands in docker, e.g. “registryget” and “registryput”, wrapping access to the local filesystem (and optionally doing consistency checks). Authentication and authorization are then delegated to SSH (e.g. with public keys).
+
+1.3 Docker
+----------
+
+On top of being a runtime for LXC, Docker is the Registry client. It supports:
+- Push / Pull on the registry
+- Client authentication on the Index
+
+2. Workflow
+===========
+
+2.1 Pull
+--------
+
+.. image:: /static_files/docker_pull_chart.png
+
+1. Contact the Index to know where I should download “samalba/busybox”
+2. Index replies:
+   a. “samalba/busybox” is on Registry A
+   b. here are the checksums for “samalba/busybox” (for all layers)
+   c. token
+3. Contact Registry A to receive the layers for “samalba/busybox” (all of them to the base image). Registry A is authoritative for “samalba/busybox” but keeps a copy of all inherited layers and serve them all from the same location.
+4. registry contacts index to verify if token/user is allowed to download images
+5. Index returns true/false lettings registry know if it should proceed or error out
+6. Get the payload for all layers
+
+It’s possible to run docker pull \https://<registry>/repositories/samalba/busybox. In this case, docker bypasses the Index. However the security is not guaranteed (in case Registry A is corrupted) because there won’t be any checksum checks.
+
+Currently registry redirects to s3 urls for downloads, going forward all downloads need to be streamed through the registry. The Registry will then abstract the calls to S3 by a top-level class which implements sub-classes for S3 and local storage.
+
+Token is only returned when the 'X-Docker-Token' header is sent with request.
+
+Basic Auth is required to pull private repos. Basic auth isn't required for pulling public repos, but if one is provided, it needs to be valid and for an active account.
+
+API (pulling repository foo/bar):
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+1. (Docker -> Index) GET /v1/repositories/foo/bar/images
+    **Headers**:
+        Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
+        X-Docker-Token: true
+    **Action**:
+        (looking up the foo/bar in db and gets images and checksums for that repo (all if no tag is specified, if tag, only checksums for those tags) see part 4.4.1)
+
+2. (Index -> Docker) HTTP 200 OK
+
+    **Headers**:
+        - Authorization: Token signature=123abc,repository=”foo/bar”,access=write
+        - X-Docker-Endpoints: registry.docker.io [, registry2.docker.io]
+    **Body**:
+        Jsonified checksums (see part 4.4.1)
+
+3. (Docker -> Registry) GET /v1/repositories/foo/bar/tags/latest
+    **Headers**:
+        Authorization: Token signature=123abc,repository=”foo/bar”,access=write
+
+4. (Registry -> Index) GET /v1/repositories/foo/bar/images
+
+    **Headers**:
+        Authorization: Token signature=123abc,repository=”foo/bar”,access=read
+
+    **Body**:
+        <ids and checksums in payload>
+
+    **Action**:
+        ( Lookup token see if they have access to pull.)
+
+        If good:
+            HTTP 200 OK
+            Index will invalidate the token
+        If bad:
+            HTTP 401 Unauthorized
+
+5. (Docker -> Registry) GET /v1/images/928374982374/ancestry
+    **Action**:
+        (for each image id returned in the registry, fetch /json + /layer)
+
+.. note::
+
+    If someone makes a second request, then we will always give a new token, never reuse tokens.
+
+2.2 Push
+--------
+
+.. image:: /static_files/docker_push_chart.png
+
+1. Contact the index to allocate the repository name “samalba/busybox” (authentication required with user credentials)
+2. If authentication works and namespace available, “samalba/busybox” is allocated and a temporary token is returned (namespace is marked as initialized in index)
+3. Push the image on the registry (along with the token)
+4. Registry A contacts the Index to verify the token (token must corresponds to the repository name)
+5. Index validates the token. Registry A starts reading the stream pushed by docker and store the repository (with its images)
+6. docker contacts the index to give checksums for upload images
+
+.. note::
+
+    **It’s possible not to use the Index at all!** In this case, a deployed version of the Registry is deployed to store and serve images. Those images are not authentified and the security is not guaranteed.
+
+.. note::
+
+    **Index can be replaced!** For a private Registry deployed, a custom Index can be used to serve and validate token according to different policies.
+
+Docker computes the checksums and submit them to the Index at the end of the push. When a repository name does not have checksums on the Index, it means that the push is in progress (since checksums are submitted at the end).
+
+API (pushing repos foo/bar):
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+1. (Docker -> Index) PUT /v1/repositories/foo/bar/
+    **Headers**:
+        Authorization: Basic sdkjfskdjfhsdkjfh==
+        X-Docker-Token: true
+
+    **Action**::
+        - in index, we allocated a new repository, and set to initialized
+
+    **Body**::
+        (The body contains the list of images that are going to be pushed, with empty checksums. The checksums will be set at the end of the push)::
+
+        [{“id”: “9e89cc6f0bc3c38722009fe6857087b486531f9a779a0c17e3ed29dae8f12c4f”}]
+
+2. (Index -> Docker) 200 Created
+    **Headers**:
+        - WWW-Authenticate: Token signature=123abc,repository=”foo/bar”,access=write
+        - X-Docker-Endpoints: registry.docker.io [, registry2.docker.io]
+
+3. (Docker -> Registry) PUT /v1/images/98765432_parent/json
+    **Headers**:
+        Authorization: Token signature=123abc,repository=”foo/bar”,access=write
+
+4. (Registry->Index) GET /v1/repositories/foo/bar/images
+    **Headers**:
+        Authorization: Token signature=123abc,repository=”foo/bar”,access=write
+    **Action**::
+        - Index:
+            will invalidate the token.
+        - Registry:
+            grants a session (if token is approved) and fetches the images id
+
+5. (Docker -> Registry) PUT /v1/images/98765432_parent/json
+    **Headers**::
+        - Authorization: Token signature=123abc,repository=”foo/bar”,access=write
+        - Cookie: (Cookie provided by the Registry)
+
+6. (Docker -> Registry) PUT /v1/images/98765432/json

+        Cookie: (Cookie provided by the Registry)
+
+7. (Docker -> Registry) PUT /v1/images/98765432_parent/layer
+    **Headers**:
+        Cookie: (Cookie provided by the Registry)
+
+8. (Docker -> Registry) PUT /v1/images/98765432/layer
+    **Headers**:
+        X-Docker-Checksum: sha256:436745873465fdjkhdfjkgh
+
+9. (Docker -> Registry) PUT /v1/repositories/foo/bar/tags/latest
+    **Headers**:
+        Cookie: (Cookie provided by the Registry)
+    **Body**:
+        “98765432”
+
+10. (Docker -> Index) PUT /v1/repositories/foo/bar/images
+
+    **Headers**:
+        Authorization: Basic 123oislifjsldfj==
+        X-Docker-Endpoints: registry1.docker.io (no validation on this right now)
+
+    **Body**:
+        (The image, id’s, tags and checksums)
+
+        [{“id”: “9e89cc6f0bc3c38722009fe6857087b486531f9a779a0c17e3ed29dae8f12c4f”,
+        “checksum”: “b486531f9a779a0c17e3ed29dae8f12c4f9e89cc6f0bc3c38722009fe6857087”}]
+
+    **Return** HTTP 204
+
+.. note::
+
+     If push fails and they need to start again, what happens in the index, there will already be a record for the namespace/name, but it will be initialized. Should we allow it, or mark as name already used? One edge case could be if someone pushes the same thing at the same time with two different shells.
+
+     If it's a retry on the Registry, Docker has a cookie (provided by the registry after token validation). So the Index won’t have to provide a new token.
+
+3. How to use the Registry in standalone mode
+=============================================
+
+The Index has two main purposes (along with its fancy social features):
+
+- Resolve short names (to avoid passing absolute URLs all the time)
+   - username/projectname -> \https://registry.docker.io/users/<username>/repositories/<projectname>/
+- Authenticate a user as a repos owner (for a central referenced repository)
+
+3.1 Without an Index
+--------------------
+Using the Registry without the Index can be useful to store the images on a private network without having to rely on an external entity controlled by dotCloud.
+
+In this case, the registry will be launched in a special mode (--standalone? --no-index?). In this mode, the only thing which changes is that Registry will never contact the Index to verify a token. It will be the Registry owner responsibility to authenticate the user who pushes (or even pulls) an image using any mechanism (HTTP auth, IP based, etc...).
+
+In this scenario, the Registry is responsible for the security in case of data corruption since the checksums are not delivered by a trusted entity.
+
+As hinted previously, a standalone registry can also be implemented by any HTTP server handling GET/PUT requests (or even only GET requests if no write access is necessary).
+
+3.2 With an Index
+-----------------
+
+The Index data needed by the Registry are simple:
+- Serve the checksums
+- Provide and authorize a Token
+
+In the scenario of a Registry running on a private network with the need of centralizing and authorizing, it’s easy to use a custom Index.
+
+The only challenge will be to tell Docker to contact (and trust) this custom Index. Docker will be configurable at some point to use a specific Index, it’ll be the private entity responsibility (basically the organization who uses Docker in a private environment) to maintain the Index and the Docker’s configuration among its consumers.
+
+4. The API
+==========
+
+The first version of the api is available here: https://github.com/jpetazzo/docker/blob/acd51ecea8f5d3c02b00a08176171c59442df8b3/docs/images-repositories-push-pull.md
+
+4.1 Images
+----------
+
+The format returned in the images is not defined here (for layer and json), basically because Registry stores exactly the same kind of information as Docker uses to manage them.
+
+The format of ancestry is a line-separated list of image ids, in age order. I.e. the image’s parent is on the last line, the parent of the parent on the next-to-last line, etc.; if the image has no parent, the file is empty.
+
+GET /v1/images/<image_id>/layer
+PUT /v1/images/<image_id>/layer
+GET /v1/images/<image_id>/json
+PUT /v1/images/<image_id>/json
+GET /v1/images/<image_id>/ancestry
+PUT /v1/images/<image_id>/ancestry
+
+4.2 Users
+---------
+
+4.2.1 Create a user (Index)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+POST /v1/users
+
+**Body**:
+    {"email": "sam@dotcloud.com", "password": "toto42", "username": "foobar"'}
+
+**Validation**:
+    - **username** : min 4 character, max 30 characters, must match the regular expression [a-z0-9_].
+    - **password**: min 5 characters
+
+**Valid**: return HTTP 200
+
+Errors: HTTP 400 (we should create error codes for possible errors)
+- invalid json
+- missing field
+- wrong format (username, password, email, etc)
+- forbidden name
+- name already exists
+
+.. note::
+
+    A user account will be valid only if the email has been validated (a validation link is sent to the email address).
+
+4.2.2 Update a user (Index)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+PUT /v1/users/<username>
+
+**Body**:
+    {"password": "toto"}
+
+.. note::
+
+    We can also update email address, if they do, they will need to reverify their new email address.
+
+4.2.3 Login (Index)
+^^^^^^^^^^^^^^^^^^^
+Does nothing else but asking for a user authentication. Can be used to validate credentials. HTTP Basic Auth for now, maybe change in future.
+
+GET /v1/users
+
+**Return**:
+    - Valid: HTTP 200
+    - Invalid login: HTTP 401
+    - Account inactive: HTTP 403 Account is not Active
+
+4.3 Tags (Registry)
+-------------------
+
+The Registry does not know anything about users. Even though repositories are under usernames, it’s just a namespace for the registry. Allowing us to implement organizations or different namespaces per user later, without modifying the Registry’s API.
+
+The following naming restrictions apply:
+
+- Namespaces must match the same regular expression as usernames (See 4.2.1.)
+- Repository names must match the regular expression [a-zA-Z0-9-_.]
+
+4.3.1 Get all tags
+^^^^^^^^^^^^^^^^^^
+
+GET /v1/repositories/<namespace>/<repository_name>/tags
+
+**Return**: HTTP 200
+    {
+    "latest": "9e89cc6f0bc3c38722009fe6857087b486531f9a779a0c17e3ed29dae8f12c4f",
+    “0.1.1”:  “b486531f9a779a0c17e3ed29dae8f12c4f9e89cc6f0bc3c38722009fe6857087”
+    }
+
+4.3.2 Read the content of a tag (resolve the image id)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+GET /v1/repositories/<namespace>/<repo_name>/tags/<tag>
+
+**Return**:
+    "9e89cc6f0bc3c38722009fe6857087b486531f9a779a0c17e3ed29dae8f12c4f"
+
+4.3.3 Delete a tag (registry)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+DELETE /v1/repositories/<namespace>/<repo_name>/tags/<tag>
+
+4.4 Images (Index)
+------------------
+
+For the Index to “resolve” the repository name to a Registry location, it uses the X-Docker-Endpoints header. In other terms, this requests always add a “X-Docker-Endpoints” to indicate the location of the registry which hosts this repository.
+
+4.4.1 Get the images
+^^^^^^^^^^^^^^^^^^^^^
+
+GET /v1/repositories/<namespace>/<repo_name>/images
+
+**Return**: HTTP 200
+    [{“id”: “9e89cc6f0bc3c38722009fe6857087b486531f9a779a0c17e3ed29dae8f12c4f”, “checksum”: “md5:b486531f9a779a0c17e3ed29dae8f12c4f9e89cc6f0bc3c38722009fe6857087”}]
+
+
+4.4.2 Add/update the images
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You always add images, you never remove them.
+
+PUT /v1/repositories/<namespace>/<repo_name>/images
+
+**Body**:
+    [ {“id”: “9e89cc6f0bc3c38722009fe6857087b486531f9a779a0c17e3ed29dae8f12c4f”, “checksum”: “sha256:b486531f9a779a0c17e3ed29dae8f12c4f9e89cc6f0bc3c38722009fe6857087”} ]
+
+**Return** 204
+
+5. Chaining Registries
+======================
+
+It’s possible to chain Registries server for several reasons:
+- Load balancing
+- Delegate the next request to another server
+
+When a Registry is a reference for a repository, it should host the entire images chain in order to avoid breaking the chain during the download.
+
+The Index and Registry use this mechanism to redirect on one or the other.
+
+Example with an image download:
+On every request, a special header can be returned:
+
+X-Docker-Endpoints: server1,server2
+
+On the next request, the client will always pick a server from this list.
+
+6. Authentication & Authorization
+=================================
+
+6.1 On the Index
+-----------------
+
+The Index supports both “Basic” and “Token” challenges. Usually when there is a “401 Unauthorized”, the Index replies this::
+
+    401 Unauthorized
+    WWW-Authenticate: Basic realm="auth required",Token
+
+You have 3 options:
+
+1. Provide user credentials and ask for a token
+
+    **Header**:
+        - Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
+        - X-Docker-Token: true
+
+    In this case, along with the 200 response, you’ll get a new token (if user auth is ok):
+    If authorization isn't correct you get a 401 response.
+    If account isn't active you will get a 403 response.
+
+    **Response**:
+        - 200 OK
+        - X-Docker-Token: Token signature=123abc,repository=”foo/bar”,access=read
+
+2. Provide user credentials only
+
+    **Header**:
+        Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
+
+3. Provide Token
+
+    **Header**:
+        Authorization: Token signature=123abc,repository=”foo/bar”,access=read
+
+6.2 On the Registry
+-------------------
+
+The Registry only supports the Token challenge::
+
+    401 Unauthorized
+    WWW-Authenticate: Token
+
+The only way is to provide a token on “401 Unauthorized” responses::
+
+    Authorization: Token signature=123abc,repository=”foo/bar”,access=read
+
+Usually, the Registry provides a Cookie when a Token verification succeeded. Every time the Registry passes a Cookie, you have to pass it back the same cookie.::
+
+    200 OK
+    Set-Cookie: session="wD/J7LqL5ctqw8haL10vgfhrb2Q=?foo=UydiYXInCnAxCi4=&timestamp=RjEzNjYzMTQ5NDcuNDc0NjQzCi4="; Path=/; HttpOnly
+
+Next request::
+
+    GET /(...)
+    Cookie: session="wD/J7LqL5ctqw8haL10vgfhrb2Q=?foo=UydiYXInCnAxCi4=&timestamp=RjEzNjYzMTQ5NDcuNDc0NjQzCi4="

+
+Introduction
+============
+
+Docker -- The Linux container runtime
+-------------------------------------
+
+Docker complements LXC with a high-level API which operates at the process level. It runs unix processes with strong guarantees of isolation and repeatability across servers.
+
+Docker is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.
+
+
+- **Heterogeneous payloads** Any combination of binaries, libraries, configuration files, scripts, virtualenvs, jars, gems, tarballs, you name it. No more juggling between domain-specific tools. Docker can deploy and run them all.
+- **Any server** Docker can run on any x64 machine with a modern linux kernel - whether it's a laptop, a bare metal server or a VM. This makes it perfect for multi-cloud deployments.
+- **Isolation** docker isolates processes from each other and from the underlying host, using lightweight containers.
+- **Repeatability** Because containers are isolated in their own filesystem, they behave the same regardless of where, when, and alongside what they run.
+

+
+
+What is a Standard Container?
+-----------------------------
+
+Docker defines a unit of software delivery called a Standard Container. The goal of a Standard Container is to encapsulate a software component and all its dependencies in
+a format that is self-describing and portable, so that any compliant runtime can run it without extra dependency, regardless of the underlying machine and the contents of the container.
+
+The spec for Standard Containers is currently work in progress, but it is very straightforward. It mostly defines 1) an image format, 2) a set of standard operations, and 3) an execution environment.
+
+A great analogy for this is the shipping container. Just like Standard Containers are a fundamental unit of software delivery, shipping containers (http://bricks.argz.com/ins/7823-1/12) are a fundamental unit of physical delivery.
+
+Standard operations
+~~~~~~~~~~~~~~~~~~~
+
+Just like shipping containers, Standard Containers define a set of STANDARD OPERATIONS. Shipping containers can be lifted, stacked, locked, loaded, unloaded and labelled. Similarly, standard containers can be started, stopped, copied, snapshotted, downloaded, uploaded and tagged.
+
+
+Content-agnostic
+~~~~~~~~~~~~~~~~~~~
+
+Just like shipping containers, Standard Containers are CONTENT-AGNOSTIC: all standard operations have the same effect regardless of the contents. A shipping container will be stacked in exactly the same way whether it contains Vietnamese powder coffee or spare Maserati parts. Similarly, Standard Containers are started or uploaded in the same way whether they contain a postgres database, a php application with its dependencies and application server, or Java build artifacts.
+
+
+Infrastructure-agnostic
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Both types of containers are INFRASTRUCTURE-AGNOSTIC: they can be transported to thousands of facilities around the world, and manipulated by a wide variety of equipment. A shipping container can be packed in a factory in Ukraine, transported by truck to the nearest routing center, stacked onto a train, loaded into a German boat by an Australian-built crane, stored in a warehouse at a US facility, etc. Similarly, a standard container can be bundled on my laptop, uploaded to S3, downloaded, run and snapshotted by a build server at Equinix in Virginia, uploaded to 10 staging servers in a home-made Openstack cluster, then sent to 30 production instances across 3 EC2 regions.
+
+
+Designed for automation
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Because they offer the same standard operations regardless of content and infrastructure, Standard Containers, just like their physical counterpart, are extremely well-suited for automation. In fact, you could say automation is their secret weapon.
+
+Many things that once required time-consuming and error-prone human effort can now be programmed. Before shipping containers, a bag of powder coffee was hauled, dragged, dropped, rolled and stacked by 10 different people in 10 different locations by the time it reached its destination. 1 out of 50 disappeared. 1 out of 20 was damaged. The process was slow, inefficient and cost a fortune - and was entirely different depending on the facility and the type of goods.
+
+Similarly, before Standard Containers, by the time a software component ran in production, it had been individually built, configured, bundled, documented, patched, vendored, templated, tweaked and instrumented by 10 different people on 10 different computers. Builds failed, libraries conflicted, mirrors crashed, post-it notes were lost, logs were misplaced, cluster updates were half-broken. The process was slow, inefficient and cost a fortune - and was entirely different depending on the language and infrastructure provider.
+
+
+Industrial-grade delivery
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are 17 million shipping containers in existence, packed with every physical good imaginable. Every single one of them can be loaded on the same boats, by the same cranes, in the same facilities, and sent anywhere in the World with incredible efficiency. It is embarrassing to think that a 30 ton shipment of coffee can safely travel half-way across the World in *less time* than it takes a software team to deliver its code from one datacenter to another sitting 10 miles away.
+
+With Standard Containers we can put an end to that embarrassment, by making INDUSTRIAL-GRADE DELIVERY of software a reality.

+CouchDB Service
+===============
+
+.. include:: example_header.inc
+
+Here's an example of using data volumes to share the same data between 2 couchdb containers.
+This could be used for hot upgrades, testing different versions of couchdb on the same data, etc.
+
+Create first database
+---------------------
+
+Note that we're marking /var/lib/couchdb as a data volume.
+
+.. code-block:: bash
+
+    COUCH1=$(docker run -d -v /var/lib/couchdb shykes/couchdb:2013-05-03)
+
+Add data to the first database
+------------------------------
+
+We're assuming your docker host is reachable at `localhost`. If not, replace `localhost` with the public IP of your docker host.
+
+.. code-block:: bash
+
+    HOST=localhost
+    URL="http://$HOST:$(docker port $COUCH1 5984)/_utils/"
+    echo "Navigate to $URL in your browser, and use the couch interface to add data"
+
+Create second database
+----------------------
+
+This time, we're requesting shared access to $COUCH1's volumes.
+
+.. code-block:: bash
+
+    COUCH2=$(docker run -d -volumes-from $COUCH1) shykes/couchdb:2013-05-03)
+
+Browse data on the second database
+----------------------------------
+
+.. code-block:: bash
+
+    HOST=localhost
+    URL="http://$HOST:$(docker port $COUCH2 5984)/_utils/"
+    echo "Navigate to $URL in your browser. You should see the same data as in the first database!"
+
+Congratulations, you are running 2 Couchdb containers, completely isolated from each other *except* for their data.

+Hello World
+===========

+
+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

+Hello World Daemon
+==================
+
+.. include:: example_header.inc
+
+The most boring daemon ever written.
+
+This example assumes you have Docker installed and with the base image already imported ``docker pull base``.
+We will use the base image to run a simple hello world daemon that will just print hello world to standard
+out every second. It will continue to do this until we stop it.
+
+**Steps:**
+
+.. code-block:: bash
+
+    CONTAINER_ID=$(docker run -d base /bin/sh -c "while true; do echo hello world; sleep 1; done")
+
+We are going to run a simple hello world daemon in a new container made from the base image.
+
+- **"docker run -d "** run a command in a new container. We pass "-d" so it runs as a daemon.
+- **"base"** is the image we want to run the command inside of.
+- **"/bin/sh -c"** is the command we want to run in the container
+- **"while true; do echo hello world; sleep 1; done"** is the mini script we want to run, that will just print hello world once a second until we stop it.
+- **$CONTAINER_ID** the output of the run command will return a container id, we can use in future commands to see what is going on with this process.
+
+.. code-block:: bash
+
+    docker logs $CONTAINER_ID
+
+Check the logs make sure it is working correctly.
+
+- **"docker logs**" This will return the logs for a container
+- **$CONTAINER_ID** The Id of the container we want the logs for.
+
+.. code-block:: bash
+
+    docker attach $CONTAINER_ID
+
+Attach to the container to see the results in realtime.
+
+- **"docker attach**" This will allow us to attach to a background process to see what is going on.
+- **$CONTAINER_ID** The Id of the container we want to attach too.
+
+.. code-block:: bash
+
+    docker ps
+
+Check the process list to make sure it is running.
+
+- **"docker ps"** this shows all running process managed by docker
+
+.. code-block:: bash
+
+    docker stop $CONTAINER_ID
+
+Stop the container, since we don't need it anymore.
+
+- **"docker stop"** This stops a container
+- **$CONTAINER_ID** The Id of the container we want to stop.
+
+.. code-block:: bash
+

+
+Node.js Web App
+===============
+
+.. include:: example_header.inc
+
+The goal of this example is to show you how you can build your own docker images
+from a parent image using a ``Dockerfile`` . We will do that by making a simple
+Node.js hello world web application running on CentOS. You can get the full
+source code at https://github.com/gasi/docker-node-hello.
+
+Create Node.js app
+++++++++++++++++++
+
+First, create a ``package.json`` file that describes your app and its
+dependencies:
+
+.. code-block:: json
+
+    {
+      "name": "docker-centos-hello",
+      "private": true,
+      "version": "0.0.1",
+      "description": "Node.js Hello World app on CentOS using docker",
+      "author": "Daniel Gasienica <daniel@gasienica.ch>",
+      "dependencies": {
+        "express": "3.2.4"
+      }
+    }
+
+Then, create an ``index.js`` file that defines a web app using the
+`Express.js <http://expressjs.com/>`_ framework:
+
+.. code-block:: javascript
+
+    var express = require('express');
+
+    // Constants
+    var PORT = 8080;
+
+    // App
+    var app = express();
+    app.get('/', function (req, res) {
+      res.send('Hello World\n');
+    });
+
+    app.listen(PORT)
+    console.log('Running on http://localhost:' + PORT);
+
+
+In the next steps, we’ll look at how you can run this app inside a CentOS
+container using docker. First, you’ll need to build a docker image of your app.
+
+Creating a ``Dockerfile``
++++++++++++++++++++++++++
+
+Create an empty file called ``Dockerfile``:
+
+.. code-block:: bash
+
+    touch Dockerfile
+
+Open the ``Dockerfile`` in your favorite text editor and add the following line
+that defines the version of docker the image requires to build
+(this example uses docker 0.3.4):
+
+.. code-block:: bash
+
+    # DOCKER-VERSION 0.3.4
+
+Next, define the parent image you want to use to build your own image on top of.
+Here, we’ll use `CentOS <https://index.docker.io/_/centos/>`_ (tag: ``6.4``)
+available on the `docker index`_:
+
+.. code-block:: bash
+
+    FROM    centos:6.4
+
+Since we’re building a Node.js app, you’ll have to install Node.js as well as
+npm on your CentOS image. Node.js is required to run your app and npm to install
+your app’s dependencies defined in ``package.json``.
+To install the right package for CentOS, we’ll use the instructions from the
+`Node.js wiki`_:
+
+.. code-block:: bash
+
+    # Enable EPEL for Node.js
+    RUN     rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
+    # Install Node.js and npm
+    RUN     yum install -y npm-1.2.17-5.el6
+
+To bundle your app’s source code inside the docker image, use the ``ADD``
+command:
+
+.. code-block:: bash
+
+    # Bundle app source
+    ADD . /src
+
+Install your app dependencies using npm:
+
+.. code-block:: bash
+
+    # Install app dependencies
+    RUN cd /src; npm install
+
+Your app binds to port ``8080`` so you’ll use the ``EXPOSE`` command to have it
+mapped by the docker daemon:
+
+.. code-block:: bash
+
+    EXPOSE  8080
+
+Last but not least, define the command to run your app using ``CMD`` which
+defines your runtime, i.e. ``node``, and the path to our app, i.e.
+``src/index.js`` (see the step where we added the source to the container):
+
+.. code-block:: bash
+
+    CMD ["node", "/src/index.js"]
+
+Your ``Dockerfile`` should now look like this:
+
+.. code-block:: bash
+
+
+    # DOCKER-VERSION 0.3.4
+    FROM    centos:6.4
+
+    # Enable EPEL for Node.js
+    RUN     rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
+    # Install Node.js and npm
+    RUN     yum install -y npm-1.2.17-5.el6
+
+    # Bundle app source
+    ADD . /src
+    # Install app dependencies
+    RUN cd /src; npm install
+
+    EXPOSE  8080
+    CMD ["node", "/src/index.js"]
+
+
+Building your image
++++++++++++++++++++
+
+Go to the directory that has your ``Dockerfile`` and run the following command
+to build a docker image. The ``-t`` flag let’s you tag your image so it’s easier
+to find later using the ``docker images`` command:
+
+.. code-block:: bash
+
+    docker build -t <your username>/centos-node-hello .
+
+Your image will now be listed by docker:
+
+.. code-block:: bash
+
+    docker images
+
+    > # Example
+    > REPOSITORY                 TAG       ID              CREATED
+    > centos                     6.4       539c0211cd76    8 weeks ago
+    > gasi/centos-node-hello     latest    d64d3505b0d2    2 hours ago
+
+
+Run the image
++++++++++++++
+
+Running your image with ``-d`` runs the container in detached mode, leaving the
+container running in the background. Run the image you previously built:
+
+.. code-block:: bash
+
+    docker run -d <your username>/centos-node-hello
+
+Print the output of your app:
+
+.. code-block:: bash
+
+    # Get container ID
+    docker ps
+
+    # Print app output
+    docker logs <container id>
+
+    > # Example
+    > Running on http://localhost:8080
+
+
+Test
+++++
+
+To test your app, get the the port of your app that docker mapped:
+
+.. code-block:: bash
+
+    docker ps
+
+    > # Example
+    > ID            IMAGE                          COMMAND              ...   PORTS
+    > ecce33b30ebf  gasi/centos-node-hello:latest  node /src/index.js         49160->8080
+
+In the example above, docker mapped the ``8080`` port of the container to
+``49160``.
+
+Now you can call your app using ``curl`` (install if needed via:
+``sudo apt-get install curl``):
+
+.. code-block:: bash
+
+    curl -i localhost:49160
+
+    > HTTP/1.1 200 OK

+docker. You can get the full source code at
