Ansible script for updating prod boxes (WIP)

updateprod.sh

#!/bin/bash
## updateprod.sh
# Updated: 2013-10-18
# Tested with: Ubuntu 12.04 x64
# Description: Script for updating production machines using ansible
# This script assumes that production machines are defined at /etc/ansible/hosts under [prod]
# The script will first use ansible with --check to show packages that will be updated and then prompt the user to continue with updating by entering (y)es or exit and NOT update packages by entering (n)o or anything else besides y. This also uses the current logged in user and the public/private key for authentication to each machine.

echo "Running ansible with --check..."
ansible prod -m apt -a "update_cache=yes upgrade=yes" --sudo --check
read -n1 -p "Upgrade packages on prod? [y,n]" UPGRADE

if [ "$UPGRADE" == "y" ]; then
    echo -e "\nUpgrading..."
    ansible prod -m apt -a "update_cache=yes upgrade=yes" --sudo
    echo -e "\nUpgrade Complete!"
    exit 1
else
    echo -e "\nAborting..."
    exit 1
