How does a running ec2 instance can know its own instance id using aws-sdk ruby gem.
I have a running ec2 instance say 'X' and I want to know its instance id using aws-sdk ruby gem. The ruby code is getting executed on the same ec2 instance 'X'

There are a bunch of solutions over here
A ruby one looks like this:
require 'rubygems'
require 'aws-sdk'
require 'net/http'
metadata_endpoint = 'http://169.254.169.254/latest/meta-data/'
instance_id = Net::HTTP.get( URI.parse( metadata_endpoint + 'instance-id' ) )
ec2 = AWS::EC2.new()
instance = ec2.instances[instance_id]
