zimbatm 13ebc68636 Makes sure the GPG key fingerprint is inlined in the doc everywhere.
Instead of `curl $url | apt-get add -` use the ubuntu keyserver and a full
fingerprint to retreive the key. This makes the distribution of the GPG key
more secure an less likely to change even if 3rd party gains access to the
packages repository.

:title: Requirements and Installation on Ubuntu Linux
:description: Please note this project is currently under heavy development. It should not be used in production.

.. _ubuntu_linux:
Ubuntu
======
.. warning::
These instructions have changed for 0.6. If you are upgrading from
an earlier version, you will need to follow them again.
.. include:: install_header.inc
Docker is supported on the following versions of Ubuntu:
- :ref:`ubuntu_precise`
- :ref:`ubuntu_raring_saucy`
Please read :ref:`ufw`, if you plan to use `UFW (Uncomplicated
Firewall) <https://help.ubuntu.com/community/UFW>`_
.. _ubuntu_precise:
Ubuntu Precise 12.04 (LTS) (64-bit)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This installation path should work at all times.
Dependencies
------------
**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 you'll
install when following these steps comes with AUFS built in. We also
include the generic headers to enable packages that depend on them,
like ZFS and the VirtualBox guest additions. If you didn't install the
headers for your "precise" kernel, then you can skip these headers for
the "raring" kernel. But it is safer to include them if you're not
sure.
.. code-block:: bash
# install the backported kernel
sudo apt-get update
sudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raring
# reboot
sudo reboot
Installation
------------
.. warning::
These instructions have changed for 0.6. If you are upgrading from
an earlier version, you will need to follow them again.
Docker is available as a Debian package, which makes installation
easy. **See the :ref:`installmirrors` section below if you are not in
the United States.** Other sources of the Debian packages may be
faster for you to install.
First add the Docker repository key to your local keychain.
.. code-block:: bash
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
Add the Docker repository to your apt sources list, update and install the
``lxc-docker`` package.
*You may receive a warning that the package isn't trusted. Answer yes to
continue installation.*
.. code-block:: bash
sudo sh -c "echo deb http://get.docker.io/ubuntu docker main\
> /etc/apt/sources.list.d/docker.list"
sudo apt-get update
sudo apt-get install lxc-docker
.. note::
There is also a simple ``curl`` script available to help with this process.
.. code-block:: bash
curl -s https://get.docker.io/ubuntu/ | sudo sh
Now verify that the installation has worked by downloading the ``ubuntu`` image
and launching a container.
.. code-block:: bash
sudo docker run -i -t ubuntu /bin/bash
Type ``exit`` to exit
**Done!**, now continue with the :ref:`hello_world` example.
.. _ubuntu_raring_saucy:
Ubuntu Raring 13.04 and Saucy 13.10 (64 bit)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These instructions cover both Ubuntu Raring 13.04 and Saucy 13.10.
Dependencies
------------
**Optional AUFS filesystem support**
Ubuntu Raring already comes with the 3.8 kernel, so we don't need to install it. However, not all systems
have AUFS filesystem support enabled. AUFS support is optional as of version 0.7, but it's still available as
a driver and we recommend using it if you can.
To make sure AUFS is installed, run the following commands:
.. code-block:: bash
sudo apt-get update
sudo apt-get install linux-image-extra-`uname -r`

**Done!**, now continue with the :ref:`hello_world` example.
.. _ufw:
Docker and UFW
^^^^^^^^^^^^^^
Docker uses a bridge to manage container networking. By default, UFW drops all
`forwarding` traffic. As a result will you need to enable UFW forwarding:
.. code-block:: bash
sudo nano /etc/default/ufw
----
# Change:
# DEFAULT_FORWARD_POLICY="DROP"
# to
DEFAULT_FORWARD_POLICY="ACCEPT"
Then reload UFW:
.. code-block:: bash
sudo ufw reload
UFW's default set of rules denies all `incoming` traffic. If you want to be
able to reach your containers from another host then you should allow
incoming connections on the Docker port (default 4243):
.. code-block:: bash
sudo ufw allow 4243/tcp
.. _installmirrors:
Mirrors
^^^^^^^
You should ``ping get.docker.io`` and compare the latency to the
following mirrors, and pick whichever one is best for you.
Yandex
------
`Yandex <http://yandex.ru/>`_ in Russia is mirroring the Docker Debian
packages, updating every 6 hours. Substitute
``http://mirror.yandex.ru/mirrors/docker/`` for
``http://get.docker.io/ubuntu`` in the instructions above. For example:
.. code-block:: bash
sudo sh -c "echo deb http://mirror.yandex.ru/mirrors/docker/ docker main\
> /etc/apt/sources.list.d/docker.list"
sudo apt-get update
sudo apt-get install lxc-docker
