#Ruby SDK

Rather than reinvent the wheel, Rackspace choose to use the popular fog gem for its SDK. Fog provides both an ActiveRecord like model interface as well as a request interface for efficent access to cloud resources.

Installation

To install Fog via RubyGems run the following command:

gem install fog

krames

#!/usr/bin/env ruby

# This example demonstrates uploading large files in segments

require 'rubygems' #required for Ruby 1.8.x
require 'fog'

# Size of segment. The Rackspace cloud currently requires files larger than 5GB to be segmented so we will choose 5GB -1 for a size
# http://docs.rackspace.com/files/api/v1/cf-devguide/content/Large_Object_Creation-d1e2019.html

#Curl and the Rackspace Cloud

This provides a quick introduction of how to use curl with the Rackspace Cloud.

Introduction

Before you can start issuing commands using curl you will need to authenticate to the Rackspace Cloud. The authentication process provides you with an authentication token and as well as a service catalog.

The authentication token is a temporary token that associates your account with your requests. The service catalog is a list of service endpoints for your account.
