 2 | ====================
 3 | 
 4 | Example playbooks to launch AWS infrastructure.
 5 | 
 6 | Steps:
 7 | 
 8 | 1. Edit vars/aws-creds.yml to include your own AWS credentials
 9 | 2. Edit vars/dev-environment.yml to define the security groups,
10 |    sets of instances, etc, that will be used.
11 | 3. Run: ansible-playbook -i hosts provision.yml
12 | 
13 | You can shut down the infrastructure by setting the exact_count values
14 | in the vars/dev-environment.yml file to 0 and re-running provision.yml.
