Right now, the officially supported distribution are:
|
|
|
|
- :ref:`fedora_core19`
|
|
|
|
Docker has the following dependencies
|
|
|
|
* Linux kernel 3.8 or later
|
|
* Device Mapper
|
|
|
|
.. _fedora_core19:
|
|
|
|
Fedora Core 19 (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 or later. Fedora Core
|
|
19 ships with 3.10 so you shouldn't need to update anything. You can confirm
|
|
the running kernel version with the ``uname`` command.
|
|
|
|
.. code-block:: bash
|
|
|
|
uname -a
|
|
Linux fedora-19.example.com 3.10.4-300.fc19.x86_64 #1 SMP Tue Jul 30 11:29:05 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
|
|
|
|
**Device Mapper**
|
|
|
|
Fedora Core 19 and later should also ship with Device Mapper that provides
|
|
Docker's filesystem layering. You can confirm Device Mapper is install by
|
|
checking for the ``sys/class/misc/device-mapper`` file.
|
|
|
|
.. code-block:: bash
|
|
|
|
ls -l /sys/class/misc/device-mapper
|
|
lrwxrwxrwx. 1 root root 0 Nov 26 03:00 /sys/class/misc/device-mapper -> ../../devices/virtual/misc/device-mapper
|
|
|
|
If the file is present then Device Mapper is available. If the file is not
|
|
present you can try to install Device Mapper.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo yum -y install device-mapper
|
|
|
|
Installation
|
|
------------
|
|
|
|
Firstly, let's make sure our Fedora host is up-to-date.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo yum -y upgrade
|
|
|
|
Next let's install the ``docker-io`` package which will install Docker on our host.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo yum -y install docker-io
|
|
|
|
Now let's verify that it worked
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo docker run -i -t ubuntu /bin/bash
|
|
|
|
**Done!**, now continue with the :ref:`hello_world` example.
