 Install instructions
 ==================
 
-Building from source
---------------------
-
-1. Make sure you have a [Go language](http://golang.org) compiler.
-
-    On a Debian/wheezy or Ubuntu 12.10 install the package:
-
-    ```bash
-
-    $ sudo apt-get install golang-go
-    ```
-
-2. Execute ``make``
-
-   This command will install all necessary dependencies and build the
-   executable that you can find in ``bin/docker``
-
-3. Should you like to see what's happening, run ``make`` with ``VERBOSE=1`` parameter:
-
-    ```bash
-
-    $ make VERBOSE=1
-    ```
-
-Installing on Ubuntu 12.04 and 12.10
-------------------------------------
-
-1. Install dependencies:
-
-    ```bash
-    sudo apt-get install lxc wget bsdtar curl
-    sudo apt-get install linux-image-extra-`uname -r`
-    ```
-
-    The `linux-image-extra` package is needed on standard Ubuntu EC2 AMIs in order to install the aufs kernel module.
-
-2. Install the latest docker binary:
-
-    ```bash
-    wget http://get.docker.io/builds/$(uname -s)/$(uname -m)/docker-master.tgz
-    tar -xf docker-master.tgz
-    ```
-
-3. Run your first container!
-
-    ```bash
-    cd docker-master
-    sudo ./docker pull base
-    sudo ./docker run -i -t base /bin/bash
-    ```
-
-    Consider adding docker to your `PATH` for simplicity.
-
-Installing on other Linux distributions
+Quick install on Ubuntu 12.04 and 12.10
 ---------------------------------------
 
-Right now, the officially supported distributions are:
+```bash
+curl get.docker.io | sh -x
+```
 
-* Ubuntu 12.04 (precise LTS)
-* Ubuntu 12.10 (quantal)
+Binary installs
+----------------
 
-Docker probably works on other distributions featuring a recent kernel, the AUFS patch, and up-to-date lxc. However this has not been tested.
+Docker supports the following binary installation methods.
+Note that some methods are community contributions and not yet officially supported.
 
-Some streamlined (but possibly outdated) installation paths' are available from the website: http://docker.io/documentation/ 
+* [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
+   ```

-Running an interactive shell
-----------------------------
+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
-# Download a base image
-docker pull base

-# Run an interactive shell in the base image,
-# allocate a tty, attach stdin and stdout
-docker run -i -t base /bin/bash
+# On a production system you want this running in an init script
+sudo docker -d &
 ```
 
-Detaching from the interactive shell
-------------------------------------
+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
 ```
-# In order to detach without killing the shell, you can use the escape sequence Ctrl-p + Ctrl-q
-# Note: this works only in tty mode (run with -t option).
+
+
+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
 ```

+
+## Spec for data volumes
+
+Spec owner: Solomon Hykes <solomon@dotcloud.com>
+
+Data volumes (issue #111) are a much-requested feature which trigger much discussion and debate. Below is the current authoritative spec for implementing data volumes.
+This spec will be deprecated once the feature is fully implemented.
+
+Discussion, requests, trolls, demands, offerings, threats and other forms of supplications concerning this spec should be addressed to Solomon here: https://github.com/dotcloud/docker/issues/111
+
+
+### 1. Creating data volumes
+
+At container creation, parts of a container's filesystem can be mounted as separate data volumes. Volumes are defined with the -v flag.
+
+For example:
+
+```bash
+$ docker run -v /var/lib/postgres -v /var/log postgres /usr/bin/postgres
+```
+
+In this example, a new container is created from the 'postgres' image. At the same time, docker creates 2 new data volumes: one will be mapped to the container at /var/lib/postgres, the other at /var/log.
+
+2 important notes:
+
+1) Volumes don't have top-level names. At no point does the user provide a name, or is a name given to him. Volumes are identified by the path at which they are mounted inside their container.
+
+2) The user doesn't choose the source of the volume. Docker only mounts volumes it created itself, in the same way that it only runs containers that it created itself. That is by design.
+
+
+### 2. Sharing data volumes
+
+Instead of creating its own volumes, a container can share another container's volumes. For example:
+
+```bash
+$ docker run --volumes-from $OTHER_CONTAINER_ID postgres /usr/local/bin/postgres-backup
+```
+
+In this example, a new container is created from the 'postgres' example. At the same time, docker will *re-use* the 2 data volumes created in the previous example. One volume will be mounted on the /var/lib/postgres of *both* containers, and the other will be mounted on the /var/log of both containers.
+
+### 3. Under the hood
+
+Docker stores volumes in /var/lib/docker/volumes. Each volume receives a globally unique ID at creation, and is stored at /var/lib/docker/volumes/ID.
+
+At creation, volumes are attached to a single container - the source of truth for this mapping will be the container's configuration.
+
+Mounting a volume consists of calling "mount --bind" from the volume's directory to the appropriate sub-directory of the container mountpoint. This may be done by Docker itself, or farmed out to lxc (which supports mount-binding) if possible.
+
+
+### 4. Backups, transfers and other volume operations
+
+Volumes sometimes need to be backed up, transfered between hosts, synchronized, etc. These operations typically are application-specific or site-specific, eg. rsync vs. S3 upload vs. replication vs...
+
+Rather than attempting to implement all these scenarios directly, Docker will allow for custom implementations using an extension mechanism.
+
+### 5. Custom volume handlers
+
+Docker allows for arbitrary code to be executed against a container's volumes, to implement any custom action: backup, transfer, synchronization across hosts, etc.
+
+Here's an example:
+
+```bash
+$ DB=$(docker run -d -v /var/lib/postgres -v /var/log postgres /usr/bin/postgres)
+
+$ BACKUP_JOB=$(docker run -d --volumes-from $DB shykes/backuper /usr/local/bin/backup-postgres --s3creds=$S3CREDS)
+
+$ docker wait $BACKUP_JOB
+```
+
+Congratulations, you just implemented a custom volume handler, using Docker's built-in ability to 1) execute arbitrary code and 2) share volumes between containers.

+Buildbot
+========
+
+Buildbot is a continuous integration system designed to automate the
+build/test cycle. By automatically rebuilding and testing the tree each time
+something has changed, build problems are pinpointed quickly, before other
+developers are inconvenienced by the failure.
+
+When running 'make hack' at the docker root directory, it spawns a virtual
+machine in the background running a buildbot instance and adds a git
+post-commit hook that automatically run docker tests for you.
+
+You can check your buildbot instance at http://192.168.33.21:8010/waterfall

+# 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.

-    It encapsulates heterogeneous payloads in Standard Containers, and runs
-    them on any server with strong guarantees of isolation and repeatability.
-    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.

-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing

+Create 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
+----------------------------------
+

+
+    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.

 Running The Examples
 --------------------
 
-There are two ways to run docker, daemon mode and standalone mode.
-
-When you run the docker command it will first check if there is a docker daemon running in the background it can connect to.
-
-* If it exists it will use that daemon to run all of the commands.
-* If it does not exist docker will run in standalone mode (docker will exit after each command).
-
-Docker needs to be run from a privileged account (root).
-
-1. The most common (and recommended) way is to run a docker daemon as root in the background, and then connect to it from the docker client from any account.
+All the examples assume your machine is running the docker daemon. To run the docker daemon in the background, simply type:
 
    .. code-block:: bash
 
-      # starting docker daemon in the background
       sudo docker -d &
 
-      # now you can run docker commands from any account.
-      docker <command>
-
-2. Standalone: You need to run every command as root, or using sudo
+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.
 
    .. code-block:: bash
 
-       sudo docker <command>
+      # now you can run docker commands from any account.

+Arch Linux
+==========
+
+  Please note this is a community contributed installation path. The only 'official' installation is using the
+  :ref:`ubuntu_linux` installation path. This version may sometimes be out of date.
+
+
+Installing on Arch Linux is not officially supported but can be handled via 
+either of the following AUR packages:
+
+* `lxc-docker <https://aur.archlinux.org/packages/lxc-docker/>`_
+* `lxc-docker-git <https://aur.archlinux.org/packages/lxc-docker-git/>`_
+
+The lxc-docker package will install the latest tagged version of docker. 
+The lxc-docker-git package will build from the current master branch.
+
+Dependencies
+------------
+
+Docker depends on several packages which are specified as dependencies in
+either AUR package.
+
+* aufs3
+* bridge-utils
+* go
+* iproute2
+* linux-aufs_friendly
+* lxc
+
+Installation
+------------
+
+The instructions here assume **yaourt** is installed.  See 
+`Arch User Repository <https://wiki.archlinux.org/index.php/Arch_User_Repository#Installing_packages>`_
+for information on building and installing packages from the AUR if you have not
+done so before.
+
+Keep in mind that if **linux-aufs_friendly** is not already installed that a
+new kernel will be compiled and this can take quite a while.
+
+::
+
+    yaourt -S lxc-docker-git
+
+
+Starting Docker
+---------------
+
+Prior to starting docker modify your bootloader to use the 
+**linux-aufs_friendly** kernel and reboot your system.
+
+There is a systemd service unit created for docker.  To start the docker service:
+
+::
+
+    sudo systemctl start docker
+
+
+To start on system boot:
+
+::
+
+    sudo systemctl enable docker

-  may be out of date because it depends on some binaries to be updated and published
-
-
-Requirements
-------------
-
-We currently rely on some Ubuntu-linux specific packages, this will change in the future, but for now we provide a
-streamlined path to install Virtualbox with a Ubuntu 12.10 image using Vagrant.
-
-1. Install virtualbox from https://www.virtualbox.org/ (or use your package manager)
-2. Install vagrant from http://www.vagrantup.com/ (or use your package manager)
-3. Install git if you had not installed it before, check if it is installed by running
-   ``git`` in a terminal window
-
-We recommend having at least about 2Gb of free disk space and 2Gb RAM (or more).
-
-Installation
-------------
-
-1. Fetch the docker sources
-
-.. code-block:: bash
-
-   git clone https://github.com/dotcloud/docker.git
-
-2. Run vagrant from the sources directory
-
-.. code-block:: bash
-
-    vagrant up
-
-Vagrant will:
-
-* Download the Quantal64 base ubuntu virtual machine image from get.docker.io/
-* Boot this image in virtualbox
-
-Then it will use Puppet to perform an initial setup in this machine:
-
-* Download & untar the most recent docker binary tarball to vagrant homedir.
-* Debootstrap to /var/lib/docker/images/ubuntu.
-* Install & run dockerd as service.
-* Put docker in /usr/local/bin.
-* Put latest Go toolchain in /usr/local/go.
-
-You now have a Ubuntu Virtual Machine running with docker pre-installed.
-
-To access the VM and use Docker, Run ``vagrant ssh`` from the same directory as where you ran
-``vagrant up``. Vagrant will make sure to connect you to the correct VM.
-
-.. code-block:: bash
-
-    vagrant ssh
-
-Now you are in the VM, run docker

+===================
+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 it is a private repo, public repos do not require tokens to be returned. The Registry will still contact the Index to make sure the pull is authorized (“is it ok to download this repos without a Token?”).
+
+API (pulling repository foo/bar):

+    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/

+
+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

+    **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>/
+   - team/projectname -> https://registry.docker.io/team/<team>/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, all lowercase no special characters. 
+    - **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.
+
+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):
+
+    **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="

+your host, or inside the VM (using make ssh-dev) and run and test docker
+inside the VM.
+
+dependencies: vagrant, virtualbox packages and python package requests
+
+
+Buildbot
+~~~~~~~~
+
+Buildbot is a continuous integration system designed to automate the
+build/test cycle. By automatically rebuilding and testing the tree each time
+something has changed, build problems are pinpointed quickly, before other
+developers are inconvenienced by the failure.
+
+When running 'make hack' at the docker root directory, it spawns a virtual
+machine in the background running a buildbot instance and adds a git
+post-commit hook that automatically run docker tests for you.
+
+You can check your buildbot instance at http://192.168.33.21:8010/waterfall

+============
+
+The only buildtime dependencies are git and go which are available via pacman.

+Building Package
+================

+Docker on Debian
+================
+
+Docker has been built and tested on Wheezy. All docker functionality works
+out of the box, except for memory limitation as the stock debian kernel
+does not support it yet.
+
+
+Building docker package
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Building Dependencies: debhelper, autotools-dev and golang
+
+
+Assuming you have a wheezy system up and running
+
+# Download a fresh copy of the docker project
+git clone https://github.com/dotcloud/docker.git
+cd docker
+
+# Get building dependencies
+sudo apt-get update ; sudo apt-get install -y debhelper autotools-dev golang
+
+# Make the debian package, with no memory limitation support
+(cd packaging/debian; make debian NO_MEMORY_LIMIT=1)
+
+
+Install docker package
+~~~~~~~~~~~~~~~~~~~~~~
+
+sudo dpkg -i lxc-docker_0.1.4-1_amd64.deb; sudo apt-get install -f -y

+Description: lxc-docker is a 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.

+Maintainer duty
+===============
+
+The Debian project specifies the role of a 'maintainer' which is the person
+making the Debian package of the program. This role requires an 'sponsor' to
+upload the package. As a maintainer you should follow the guide
+http://www.debian.org/doc/manuals/maint-guide . Your sponsor will be there
+helping you succeed.
+
+The most relevant information to update is the changelog file:
+Each new release should create a new first paragraph with new release version,
+changes, and the maintainer information.
+
+After this is done, follow README.debian to generate the actual source
+packages and talk with your sponsor to upload them into the official Debian
+package archive.

+Docker on Ubuntu
+================
+
+The easiest way to get docker up and running natively on Ubuntu is installing
+it from its official PPA::
+
+  sudo sh -c "echo 'deb http://ppa.launchpad.net/dotcloud/lxc-docker/ubuntu precise main' >>/etc/apt/sources.list"
+  sudo apt-get update

+
+
+Building docker package
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The building process is shared by both, developers and maintainers. If you are
+a developer, the Makefile will stop with exit status 2 right before signing
+the built packages.
+
+Assuming you are working on an Ubuntu 12.04 TLS system ::
+

+Description: lxc-docker is a 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.
