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 apt-get install python
run apt-get install python-pip
run pip install django
run apt-get install curl
run curl http://github.com/shykes/helloflask/helloflask/master.tar.gz | tar -zxv

The spec for Standard Containers is currently a 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.

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
Buildbot dependencies

Working with the repository
============================
Connecting to the repository
----------------------------
You create a user on the central docker repository by running
.. code-block:: bash
docker login
If your username does not exist it will prompt you to also enter a password and your e-mail address. It will then
automatically log you in.
Committing a container to a named image
---------------------------------------
In order to commit to the repository it is required to have committed your container to an image with your namespace.
.. code-block:: bash
# for example docker commit $CONTAINER_ID dhrp/kickassapp
docker commit <container_id> <your username>/<some_name>
Pushing a container to the repository
-----------------------------------------
In order to push an image to the repository you need to have committed your container to a named image (see above)
Now you can commit this image to the repository
.. code-block:: bash
# for example docker push dhrp/kickassapp
docker push <image-name>

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.

:title: Kernel Requirements
:description: Kernel supports
:keywords: kernel requirements, kernel support, docker, installation, cgroups, namespaces
.. _kernel:
Kernel Requirements
===================
The officially supported kernel is the one recommended by the
:ref:`ubuntu_linux` installation path. It is the one that most developers
will use, and the one that receives the most attention from the core
contributors. If you decide to go with a different kernel and hit a bug,
please try to reproduce it with the official kernels first.
If for some reason you cannot or do not want to use the "official" kernels,
here is some technical background about the features (both optional and
mandatory) that docker needs to run successfully.
In short, you need kernel version 3.8 (or above), compiled to include
`AUFS support <http://aufs.sourceforge.net/>`_. Of course, you need to
enable cgroups and namespaces.
Namespaces and Cgroups
----------------------
You need to enable namespaces and cgroups, to the extend of what is needed
to run LXC containers. Technically, while namespaces have been introduced
in the early 2.6 kernels, we do not advise to try any kernel before 2.6.32
to run LXC containers. Note that 2.6.32 has some documented issues regarding
network namespace setup and teardown; those issues are not a risk if you
run containers in a private environment, but can lead to denial-of-service
attacks if you want to run untrusted code in your containers. For more details,
see `[LP#720095 <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/720095>`_.
Kernels 2.6.38, and every version since 3.2, have been deployed successfully
to run containerized production workloads. Feature-wise, there is no huge
improvement between 2.6.38 and up to 3.6 (as far as docker is concerned!).
Starting with version 3.7, the kernel has basic support for
`Checkpoint/Restore In Userspace <http://criu.org/>`_, which is not used by
docker at this point, but allows to suspend the state of a container to
disk and resume it later.
Version 3.8 provides improvements in stability, which are deemed necessary
for the operation of docker. Versions 3.2 to 3.5 have been shown to
exhibit a reproducible bug (for more details, see issue
`#407 <https://github.com/dotcloud/docker/issues/407>`_).
Version 3.8 also brings better support for the
`setns() syscall <http://lwn.net/Articles/531381/>`_ -- but this should not
be a concern since docker does not leverage on this feature for now.
If you want a technical overview about those concepts, you might
want to check those articles on dotCloud's blog:
`about namespaces <http://blog.dotcloud.com/under-the-hood-linux-kernels-on-dotcloud-part>`_
and `about cgroups <http://blog.dotcloud.com/kernel-secrets-from-the-paas-garage-part-24-c>`_.
Important Note About Pre-3.8 Kernels
------------------------------------
As mentioned above, kernels before 3.8 are not stable when used with docker.
In some circumstances, you will experience kernel "oopses", or even crashes.
The symptoms include:
- a container being killed in the middle of an operation (e.g. an ``apt-get``
command doesn't complete);
- kernel messages including mentioning calls to ``mntput`` or
``d_hash_and_lookup``;
- kernel crash causing the machine to freeze for a few minutes, or even
completely.
While it is still possible to use older kernels for development, it is
really not advised to do so.
Docker checks the kernel version when it starts, and emits a warning if it
detects something older than 3.8.
See issue `#407 <https://github.com/dotcloud/docker/issues/407>`_ for details.
Extra Cgroup Controllers
------------------------
Most control groups can be enabled or disabled individually. For instance,
you can decide that you do not want to compile support for the CPU or memory
controller. In some cases, the feature can be enabled or disabled at boot
time. It is worth mentioning that some distributions (like Debian) disable
"expensive" features, like the memory controller, because they can have
a significant performance impact.
In the specific case of the memory cgroup, docker will detect if the cgroup
is available or not. If it's not, it will print a warning, and it won't
use the feature. If you want to enable that feature -- read on!
Memory and Swap Accounting on Debian/Ubuntu
-------------------------------------------
If you use Debian or Ubuntu kernels, and want to enable memory and swap
accounting, you must add the following command-line parameters to your kernel::
cgroup_enable=memory swapaccount
On Debian or Ubuntu systems, if you use the default GRUB bootloader, you can
add those parameters by editing ``/etc/default/grub`` and extending
``GRUB_CMDLINE_LINUX``. Look for the following line::
GRUB_CMDLINE_LINUX=""
And replace it by the following one::
GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount"
Then run ``update-grub``, and reboot.
AUFS
----
Docker currently relies on AUFS, an unioning filesystem.
While AUFS is included in the kernels built by the Debian and Ubuntu
distributions, is not part of the standard kernel. This means that if
you decide to roll your own kernel, you will have to patch your
kernel tree to add AUFS. The process is documented on
`AUFS webpage <http://aufs.sourceforge.net/>`_.
Note: the AUFS patch is fairly intrusive, but for the record, people have
successfully applied GRSEC and AUFS together, to obtain hardened production
kernels.
If you want more information about that topic, there is an
`article about AUFS on dotCloud's blog
<http://blog.dotcloud.com/kernel-secrets-from-the-paas-garage-part-34-a>`_.
BTRFS, ZFS, OverlayFS...
------------------------
There is ongoing development on docker, to implement support for
`BTRFS <http://en.wikipedia.org/wiki/Btrfs>`_
(see github issue `#443 <https://github.com/dotcloud/docker/issues/443>`_).
People have also showed interest for `ZFS <http://en.wikipedia.org/wiki/ZFS>`_
(using e.g. `ZFS-on-Linux <http://zfsonlinux.org/>`_) and OverlayFS.
The latter is functionally close to AUFS, and it might end up being included
in the stock kernel; so it's a strong candidate!
Would you like to `contribute

:title: Rackspace Cloud Installation

:keywords: Rackspace Cloud, installation, docker, linux, ubuntu
===============
Rackspace Cloud
===============
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 Docker on Ubuntu proviced by Rackspace is pretty straightforward, and you should mostly be able to follow the
:ref:`ubuntu_linux` installation guide.
**However, there is one caveat:**
If you are using any linux not already shipping with the 3.8 kernel you will need to install it. And this is a little
more difficult on Rackspace.
Rackspace boots their servers using grub's menu.lst and does not like non 'virtual' packages (e.g. xen compatible)
kernels there, although they do work. This makes ``update-grub`` to not have the expected result, and you need to
set the kernel manually.
**Do not attempt this on a production machine!**
.. code-block:: bash
# update apt
apt-get update
# install the new kernel
apt-get install linux-generic-lts-raring
Great, now you have kernel installed in /boot/, next is to make it boot next time.
.. code-block:: bash
# find the exact names
find /boot/ -name '*3.8*'
# this should return some results
Now you need to manually edit /boot/grub/menu.lst, you will find a section at the bottom with the existing options.
Copy the top one and substitute the new kernel into that. Make sure the new kernel is on top, and double check kernel
and initrd point to the right files.
Make special care to double check the kernel and initrd entries.
.. code-block:: bash
# now edit /boot/grub/menu.lst
vi /boot/grub/menu.lst
It will probably look something like this:
::
## ## End Default Options ##
title Ubuntu 12.04.2 LTS, kernel 3.8.x generic
root (hd0)
kernel /boot/vmlinuz-3.8.0-19-generic root=/dev/xvda1 ro quiet splash console=hvc0
initrd /boot/initrd.img-3.8.0-19-generic

root (hd0)
kernel /boot/vmlinuz-3.2.0-38-virtual root=/dev/xvda1 ro quiet splash single
initrd /boot/initrd.img-3.2.0-38-virtual
Reboot server (either via command line or console)
.. code-block:: bash
# reboot
Verify the kernel was updated
.. code-block:: bash
uname -a
# Linux docker-12-04 3.8.0-19-generic #30~precise1-Ubuntu SMP Wed May 1 22:26:36 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Right now, the officially supported distributions are:

Docker has the following dependencies
* Linux kernel 3.8
* AUFS file system support (we are working on BTRFS support as an alternative)

Ubuntu Precise 12.04 (LTS) (64-bit)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This installation path should work at all times.

- Ubuntu 12.10 (quantal) (64-bit)
Dependencies
------------
The linux-image-extra package is only needed on standard Ubuntu EC2 AMIs in order to install the aufs kernel module.
**Linux kernel 3.8**
Due to a bug in LXC docker works best on the 3.8 kernel. Precise comes with a 3.2 kernel, so we need to upgrade it. The kernel we install comes with AUFS built in.
.. code-block:: bash
sudo apt-get install linux-image-extra-`uname -r` lxc bsdtar

Upgrading
============
These instructions are for upgrading your Docker binary for when you had a custom (non package manager) installation.
If you istalled docker using apt-get, use that to upgrade.
**These instructions are for upgrading Docker**
Get the latest docker binary:
After normal installation
-------------------------
::
If you installed Docker normally using apt-get or used Vagrant, use apt-get to upgrade.
wget http://get.docker.io/builds/$(uname -s)/$(uname -m)/docker-latest.tgz
.. code-block:: bash
# update your sources list
sudo apt-get update
# install the latest
sudo apt-get install lxc-docker
After manual installation
-------------------------
Unpack it to your current dir
If you installed the Docker binary
::
.. code-block:: bash
# kill the running docker daemon
killall docker
.. code-block:: bash
# get the latest binary
wget http://get.docker.io/builds/Linux/x86_64/docker-latest.tgz
.. code-block:: bash
# Unpack it to your current dir
tar -xf docker-latest.tgz
Stop your current daemon. How you stop your daemon depends on how you started it.
Start docker in daemon mode (-d) and disconnect (&) starting ./docker will start the version in your current dir rather than a version which
might reside in your path.
- If you started the daemon manually (``sudo docker -d``), you can just kill the process: ``killall docker``
- If the process was started using upstart (the ubuntu startup daemon), you may need to use that to stop it
Start docker in daemon mode (-d) and disconnect (&) starting ./docker will start the version in your current dir rather
than the one in your PATH.
Now start the daemon
::
.. code-block:: bash
# start the new version
sudo ./docker -d &

:title: Docker Builder
:description: Docker Builder specifes a simple DSL which allows you to automate the steps you would normally manually take to create an image.
:keywords: builder, docker, Docker Builder, automation, image creation
==============
Docker Builder
==============
.. contents:: Table of Contents
Docker Builder specifes a simple DSL which allows you to automate the steps you
would normally manually take to create an image. Docker Build will run your
steps and commit them along the way, giving you a final image.
1. Usage
========
To use Docker Builder, assemble the steps into a text file (commonly referred to
as a Dockerfile) and supply this to `docker build` on STDIN, like so:
``docker build < Dockerfile``
Docker will run your steps one-by-one, committing the result if necessary,
before finally outputting the ID of your new image.
2. Format
=========
The Dockerfile format is quite simple:
``instruction arguments``
The Instruction is not case-sensitive, however convention is for them to be
UPPERCASE in order to distinguish them from arguments more easily.
Dockerfiles are evaluated in order, therefore the first instruction must be
`FROM` in order to specify the base image from which you are building.
Docker will ignore lines in Dockerfiles prefixed with "`#`", so you may add
comment lines. A comment marker in the rest of the line will be treated as an
argument.
2. Instructions
===============
Docker builder comes with a set of instructions, described below.
2.1 FROM
--------
``FROM <image>``
The `FROM` instruction sets the base image for subsequent instructions. As such,
a valid Dockerfile must have it as its first instruction.
`FROM` can be included multiple times within a single Dockerfile in order to
create multiple images. Simply make a note of the last image id output by the
commit before each new `FROM` command.
2.2 MAINTAINER
--------------
``MAINTAINER <name>``
The `MAINTAINER` instruction allows you to set the Author field of the generated
images.
2.3 RUN
-------
``RUN <command>``
The `RUN` instruction will execute any commands on the current image and commit
the results. The resulting committed image will be used for the next step in the
Dockerfile.
Layering `RUN` instructions and generating commits conforms to the
core concepts of Docker where commits are cheap and containers can be created
from any point in an image's history, much like source control.
2.4 CMD
-------
``CMD <command>``
The `CMD` instruction sets the command to be executed when running the image.
This is functionally equivalent to running
`docker commit -run '{"Cmd": <command>}'` outside the builder.
.. note::
Don't confuse `RUN` with `CMD`. `RUN` actually runs a command and commits
the result; `CMD` does not execute anything at build time, but specifies the
intended command for the image.
2.5 EXPOSE
----------
``EXPOSE <port> [<port>...]``
The `EXPOSE` instruction sets ports to be publicly exposed when running the
image. This is functionally equivalent to running
`docker commit -run '{"PortSpecs": ["<port>", "<port2>"]}'` outside the builder.
2.6 ENV
-------
``ENV <key> <value>``
The `ENV` instruction sets the environment variable `<key>` to the value
`<value>`. This value will be passed to all future ``RUN`` instructions. This is
functionally equivalent to prefixing the command with `<key>=<value>`
.. note::
The environment variables will persist when a container is run from the resulting image.
2.7 INSERT
----------
``INSERT <file url> <path>``
The `INSERT` instruction will download the file from the given url to the given
path within the image. It is similar to `RUN curl -o <path> <url>`, assuming
curl was installed within the image.
.. note::
The path must include the file name.
.. note::
This instruction has temporarily disabled
3. Dockerfile Examples
======================
.. code-block:: bash
# Nginx

RUN apt-get install -y x11vnc xvfb firefox
RUN mkdir /.vnc
# Setup a password
RUN x11vnc -storepasswd 1234 ~/.vnc/passwd
# Autostart firefox (might not be the best way, but it does the trick)
RUN bash -c 'echo "firefox" >> /.bashrc'
EXPOSE 5900
CMD ["x11vnc", "-forever", "-usepw", "-create"]
.. code-block:: bash
# Multiple images example
#
# VERSION 0.1
FROM ubuntu
RUN echo foo > bar
# Will output something like ===> 907ad6c2736f
FROM ubuntu
RUN echo moo > oink
# Will output something like ===> 695d7793cbe4
# You'll now have two images, 907ad6c2736f with /bar, and 695d7793cbe4 with
# /oink.

:title: Puppet Usage
:description: Installating and using Puppet
:keywords: puppet, installation, usage, docker, documentation
.. _install_using_puppet:
Using Puppet
=============
.. note::
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.
Requirements
------------
To use this guide you'll need a working installation of Puppet from `Puppetlabs <https://www.puppetlabs.com>`_ .
The module also currently uses the official PPA so only works with Ubuntu.
Installation
------------
The module is available on the `Puppet Forge <https://forge.puppetlabs.com/garethr/docker/>`_
and can be installed using the built-in module tool.
.. code-block:: bash
puppet module install garethr/docker
It can also be found on `GitHub <https://www.github.com/garethr/garethr-docker>`_
if you would rather download the source.
Usage
-----
The module provides a puppet class for installing docker and two defined types
for managing images and containers.
Installation
~~~~~~~~~~~~
.. code-block:: ruby
include 'docker'
Images
~~~~~~
The next step is probably to install a docker image, for this we have a
defined type which can be used like so:
.. code-block:: ruby
docker::image { 'base': }
This is equivalent to running:
.. code-block:: bash
docker pull base
Note that it will only if the image of that name does not already exist.
This is downloading a large binary so on first run can take a while.
For that reason this define turns off the default 5 minute timeout
for exec. Note that you can also remove images you no longer need with:
.. code-block:: ruby
docker::image { 'base':
ensure => 'absent',
}
Containers
~~~~~~~~~~
Now you have an image you can run commands within a container managed by
docker.
.. code-block:: ruby
docker::run { 'helloworld':
image => 'base',
command => '/bin/sh -c "while true; do echo hello world; sleep 1; done"',
}
This is equivalent to running the following command, but under upstart:
.. code-block:: bash
docker run -d base /bin/sh -c "while true; do echo hello world; sleep 1; done"
Run also contains a number of optional parameters:
.. code-block:: ruby
docker::run { 'helloworld':
image => 'base',
command => '/bin/sh -c "while true; do echo hello world; sleep 1; done"',
ports => ['4444', '4555'],
volumes => ['/var/lib/counchdb', '/var/log'],
volumes_from => '6446ea52fbc9',
memory_limit => 10485760, # bytes
username => 'example',
hostname => 'example.com',
env => ['FOO=BAR', 'FOO2=BAR2'],
dns => ['8.8.8.8', '8.8.4.4'],
}
Note that ports, env, dns and volumes can be set with either a single string
or as above with an array of values.

:title: Working With Repositories

:keywords: repo, repositiores, usage, pull image, push image, image, documentation
.. _working_with_the_repository:
Working with the repository
============================
Top-level repositories and user repositories
--------------------------------------------
Generally, there are two types of repositories: Top-level repositories which are controlled by the people behind
Docker, and user repositories.
* Top-level repositories can easily be recognized by not having a / (slash) in their name. These repositories can
generally be trusted.
* User repositories always come in the form of <username>/<repo_name>. This is what your published images will look like.
* User images are not checked, it is therefore up to you whether or not you trust the creator of this image.
Find public images available on the index
-----------------------------------------
Seach by name, namespace or description
.. code-block:: bash
docker search <value>
Download them simply by their name
.. code-block:: bash
docker pull <value>
Very similarly you can search for and browse the index online on https://index.docker.io
Connecting to the repository
----------------------------
You can create a user on the central docker repository online, or by running
.. code-block:: bash
docker login
If your username does not exist it will prompt you to also enter a password and your e-mail address. It will then
automatically log you in.
Committing a container to a named image
---------------------------------------
In order to commit to the repository it is required to have committed your container to an image with your namespace.
.. code-block:: bash
# for example docker commit $CONTAINER_ID dhrp/kickassapp
docker commit <container_id> <your username>/<some_name>
Pushing a container to the repository
-----------------------------------------
In order to push an image to the repository you need to have committed your container to a named image (see above)
Now you can commit this image to the repository
.. code-block:: bash
# for example docker push dhrp/kickassapp
docker push <image-name>
