Small bash script to automate deployment of flask apps with ansible on a EC2 instance.

Checkout the terraform branch to see a somewhat more polished approach using terraform. There should be a beanstalk branch soon as well. 

Dependencies:
- bash 4+
- fully configured aws cli, tested with the AWS free tier
- ansible 2+
Tested and developed on OSX 10.9 with up to date homebrew and Ubuntu 16.04 with default repos.

Usage:
- git clone git@github.com:marikgoran/hello-aws.git
- cd hello-aws
- ./hello.sh 

Notes:
  The hello.sh script will create the EC2 ssh key in the current working directory, create a security group in EC2 and launch a ubuntu 14.04 t2.micro instance.
  Once the instance is booted, it will run the playbook.yaml against it with ansible-playbook. 
  The playbook with configure the instance with gunicorn and deploy a small flask app on port 8000. 
  The flask app is hardcoded to https://github.com/marikgoran/hello-flask in the playbook.yaml for simplicity, but it can be easily passed as var or template to ansible. 
  
Bugs and errors:
  * The deployment script will not terminate the instance. Make sure to terminate it manually *
  You can run the script as many time as needed, but on each run a new EC2 instance will be deployed.
