How to set ruby variables in ruby script to shell environment variables

I want to write a ruby script using fog (a wrapper for aws-sdk). Of course I could hard code my aws secret key and ID but would like to be able to have it set dynamically to my shell env variable since I manage multiple accounts. 

require 'fog'
require 'json'
require 'logger'

aws_key_id = $aws_key_id
aws_secret_key = $aws_secret_key
queue_url = $sqs_queue_url

Would this work?

In ruby you use ENV to access those values. 

require 'fog'
require 'json'
require 'logger'

aws_key_id = ENV['aws_key_id']
aws_secret_key = ENV['aws_secret_key']
queue_url = ENV['sqs_queue_url']

If you want to provide default values, you can use ENV.fetch('key', [default]): ENV.fetch('sqs_queue_url', 'http://localhost')
