Running playbooks

Create EC2 Security Groups

ansible-playbook -i localhost create_security_group.yml

Create RDS instance, database and import sample data

ansible-playbook -i localhost create_rds.yml

Create EC2 instances

ansible-playbook -i localhost create_ec2_instances.yml

Above 3 playbooks can be run at once by

ansible-playbook -i localhost create_env.yml

Note: Currently there is a bug in boto RDS module that returns TypeError and can be fixed by body = response.read().decode('utf-8') in rds2/layer1.py. See boto/boto#2677.

Deploying application

ansible-playbook -u ubuntu deploy_app.yml
