AWS::EC2::Clientクライアントを使って色々とdescribeするサンプル

aws-describe.rb

# -*- coding: utf-8 -*-
require 'aws-sdk'
 
ACCESS_KEY = "set your access key id"
SECRET_KEY = "set your secret key"
REGION = 'ec2.ap-northeast-1.amazonaws.com'
 
ec2 = AWS::EC2.new(
  :access_key_id => ACCESS_KEY,
  :secret_access_key => SECRET_KEY,
  :ec2_endpoint => REGION
).client

## EC2インスタンスの場合
ec2.describe_instances(options = {:instance_ids => ["i-xxxxxxxx"]})

## このような形に省力する事も出来ます ※以降の内容も同様に省略可能です
ec2.describe_instances(:instance_ids => ["i-xxxxxxxx"])
