# Getting Started with Fog and the Rackspace Cloud
|
|
|
|
This document explains how to get started using Fog with the [Rackspace Cloud](http://www.rackspace.com/cloud/).
|
|
|
|
## Requirements
|
|
|
|
### Ruby
|
|
|
|
Fog officially supports Ruby 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 1.9.3 is suggested for new projects. For information on installing Ruby please refer to the [Ruby download page](http://www.ruby-lang.org/en/downloads/).
|
|
|
|
### RubyGems
|
|
|
|
RubyGems is required to access the Fog gem. For information on installing RubyGems, please refer to [RubyGems download page](http://rubygems.org/pages/download).
|
|
|
|
### Bundler (optional)
|
|
|
|
Bundler helps manage gem dependencies and is recommended for new projects. For more information about bundler, please refer to the [bundler documentation](http://gembundler.com/).
|
|
|
|
## Credentials
|
|
|
|
To obtain credentials for the US Rackspace Cloud, please sign up for an account at [US Rackspace Open Cloud](https://cart.rackspace.com/cloud/). Once an account is created, you can login to the [Cloud Control Panel (US)](https://mycloud.rackspace.com/), find your credentials by clicking on your username in the top right corner, and then select API keys.
|
|
|
|
Likewise, you can create an account on our UK Rackspace Open Cloud by signing up at [UK Rackspace Open Cloud](https://buyonline.rackspace.co.uk/cloud/userinfo?type=normal) and then logging into [Cloud Control Panel (UK)](https://mycloud.rackspace.co.uk/).
|
|
|
|
You will use the credentials when you explore fog services in the [Next Steps](#next-steps) section.
|
|
|
|
## 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::Rackspace.services
|
|
|
|
These services can be explored in further depth in the following documents:
|
|
|
|
* [Next Generation Cloud Servers™ (compute_v2)](compute_v2.md)
|
|
* [Cloud Files™ (storage)](storage.md)
|
|
* [Cloud Block Storage (block_storage)](block_storage.md)
|
|
* [Auto Scale (auto_scale)](auto_scale.md)
|
|
|
|
**Note**: The compute service provides an interface to the First Geneneration Cloud Servers™ (compute). This service is deprecated. Users are encouraged to use Next Geneneration Cloud Servers™ (compute_v2).
