## 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](http://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
include_recipe 'docker'
### Images
The next step is to pull a Docker image. For this, we have a resource:
docker_image 'samalba/docker-registry'
This is equivalent to running:
$ sudo 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:
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.
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:
$ sudo 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.
