Getting Started with Fog and OpenStack
This document explains how to get started using Fog with OpenStack
Requirements
Ruby
Fog officially supports Ruby 2.0.0, 1.9.3, 1.9.2, and 1.8.7 (also known as Matz Ruby Interpreter or MRI). While not officially supported, fog has been known to work with Rubinus and JRuby.
Ruby 2.0.0 is suggested for new projects. For information on installing Ruby please refer to the Ruby download page.
RubyGems
RubyGems is required to access the Fog gem. For information on installing RubyGems, please refer to RubyGems download page.
Bundler (optional)
Bundler helps manage gem dependencies and is recommended for new projects. For more information about bundler, please refer to the bundler documentation.
Installation
To install Fog via RubyGems run the following command:
$ gem install fog
To install Fog via Bundler add gem 'fog' to your Gemfile. This is a sample Gemfile to install Fog:
source 'https://rubygems.org'
gem 'fog'
After creating your Gemfile execute the following command to install the libraries:
bundle install
Next Steps
Now that you have installed Fog and obtained your credentials, you are ready to begin exploring the capabilities of the Rackspace Open Cloud and Fog using irb.
Start by executing the following command:
irb
Once irb has launched you will need to require the Fog library.
If using Ruby 1.8.x execute the following command:
require 'rubygems'
require 'fog'
If using Ruby 1.9.x execute the following command:
require 'fog'
You should now be able to execute the following command to see a list of services Fog provides for the Rackspace Open Cloud:
Fog::OpenStack.services
These services can be explored in further depth in the following documents:
