Last active August 26, 2015 18:59 — forked from kixorz/ec2hostname.rb
EC2 DNS load-balancing init.d script. Instances automatically register themselves in Route53 RecordSets and properly update their records when starting/shutting down. Instances need to use attached IAM role allowing them to modify the Route53 zone.
