Fog::Aws

Installation

Add this line to your application's Gemfile:

gem 'fog-aws'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fog-aws

Usage

Before you can use fog-aws, you must require it in your application:

require 'fog/aws'

Since it's a bad practice to have your credentials in source code, you should load them from default fog configuration file: ~/.fog. This file could look like this:

default:
  aws_access_key_id:     <YOUR_ACCESS_KEY_ID>
  aws_secret_access_key: <YOUR_SECRET_ACCESS_KEY>

Connecting to EC2 service

ec2 = Fog::Compute.new :provider => 'AWS', :region => 'us-west-2'

You can review all the requests available with this service using #requests method:

ec2.requests # => [:allocate_address, :assign_private_ip_addresses, :associate_address, ...]

Launch an EC2 on-demand instance:

response = ec2.run_instances(
  "ami-23ebb513",
  1,
  1,
  "InstanceType"  => "t1.micro",
  "SecurityGroup" => "ssh",
  "KeyName"       => "miguel"
)
instance_id = response.body["instancesSet"].first["instanceId"] # => "i-02db5af4"
instance = ec2.servers.get(instance_id)
instance.wait_for { ready? }
puts instance.public_ip_address # => "356.300.501.20"

Terminate an EC2 instance:

instance = ec2.servers.get("i-02db5af4")
instance.destroy

Fog::AWS is more than EC2 since it supports many services provided by AWS. The best way to learn and to know about how many services are supported is to take a look at the source code. To review the tests directory and to play with the library in irb can be very helpful resources as well.
