ansible aws

README.md

you must set up a security group ansible-test on ec2

the basic requirement is for inbound ssh and i used my ip as the allowed traffic source

remember! t2 instances must be launched in VPC, so you have to create a VPC security group if not using default

also you must specify a subnet id or network interface id

subnets can be found with: ec2-describe-subnets

key_name is the name of the ec2 key you have set up on the ec2 console

for this example, we are using region us-east-1 and ami ami-9a562df2 (ubuntu 14)

note: the hosts file will not be modified, the new instance ip is only stored in memory while executing tasks in the playbook

sudo pip install boto

ansible-playbook -i hosts demo_setup.yml

creds.sh

#!/bin/bash

# this file must be run with `source creds.sh`

export AWS_ACCESS_KEY_ID='foo'
export AWS_SECRET_ACCESS_KEY='bar'
