Using Chef
|
||
|
|
=============
|
||
|
|
|
||
|
|
.. 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 This version may sometimes be out of date.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
|
||
|
|
`Chef <http://www.getchef.com/>`_. This cookbook supports a variety of
|
||
|
|
operating systems.
|
||
|
|
|
||
|
|
Installation
|
||
|
|
------------
|
||
|
|
|
||
|
|
The cookbook is available on the `Chef Community Site
|
||
|
|
<community.opscode.com/cookbooks/docker>`_ and can be installed
|
||
|
|
using your favorite cookbook dependency manager.
|
||
|
|
|
||
|
|
The source can be found on `GitHub
|
||
|
|
<https://github.com/bflad/chef-docker>`_.
|
||
|
|
|
||
|
|
Usage
|
||
|
|
-----
|
||
|
|
|
||
|
|
The cookbook provides recipes for installing Docker, configuring init
|
||
|
|
for Docker, and resources for managing images and containers.
|
||
|
|
It supports almost all Docker functionality.
|
||
|
|
|
||
|
|
Installation
|
||
|
|
~~~~~~~~~~~~
|
||
|
|
|
||
|
|
.. code-block:: ruby
|
||
|
|
|
||
|
|
include_recipe 'docker'
|
||
|
|
|
||
|
|
Images
|
||
|
|
~~~~~~
|
||
|
|
|
||
|
|
The next step is to pull a Docker image. For this, we have a resource:
|
||
|
|
|
||
|
|
.. code-block:: ruby
|
||
|
|
|
||
|
|
docker_image 'samalba/docker-registry'
|
||
|
|
|
||
|
|
This is equivalent to running:
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
docker pull samalba/docker-registry
|
||
|
|
|
||
|
|
There are attributes available to control how long the cookbook
|
||
|
|
will allow for downloading (5 minute default).
|
||
|
|
|
||
|
|
To remove images you no longer need:
|
||
|
|
|
||
|
|
.. code-block:: ruby
|
||
|
|
|
||
|
|
docker_image 'samalba/docker-registry' do
|
||
|
|
action :remove
|
||
|
|
end
|
||
|
|
|
||
|
|
Containers
|
||
|
|
~~~~~~~~~~
|
||
|
|
|
||
|
|
Now you have an image where you can run commands within a container
|
||
|
|
managed by Docker.
|
||
|
|
|
||
|
|
.. code-block:: ruby
|
||
|
|
|
||
|
|
docker_container 'samalba/docker-registry' do
|
||
|
|
detach true
|
||
|
|
port '5000:5000'
|
||
|
|
env 'SETTINGS_FLAVOR=local'
|
||
|
|
volume '/mnt/docker:/docker-storage'
|
||
|
|
end
|
||
|
|
|
||
|
|
This is equivalent to running the following command, but under upstart:
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
docker run --detach=true --publish='5000:5000' --env='SETTINGS_FLAVOR=local' --volume='/mnt/docker:/docker-storage' samalba/docker-registry
|
||
|
|
|
||
|
|
The resources will accept a single string or an array of values
|
||
|
|
for any docker flags that allow multiple values.
