                Blue-Green AWS Auto Scaling Deployments with Terraform
              
          
    A quick note on how I'm currently handling Blue/Green or A/B deployments with Terraform and AWS EC2 Auto Scaling.
In my particular use case, I want to be able to inspect an AMI deployment manually before disabling the previous deployment.
Hopefully someone finds this useful, and if you have and feedback please leave a comment or email me.
Overview

I build my AMI's using Packer and Ansible.

  
## CiscoKeyGen.py
#! /usr/bin/python
print "\n*********************************************************************"
print "Cisco IOU License Generator - Kal 2011, python port of 2006 C version"
import os
import socket
import hashlib
import struct
# get the host id and host name to calculate the hostkey
hostid=os.popen("hostid").read().strip()
hostname = socket.gethostname()

This playbook has been removed as it is now very outdated.
