Watch here for YouTube Video:
Pre-requistes:
Ansible is installed and Boto is also installed on Ubuntu EC2 instance
Make sure you create an IAM role with AmazonEC2FullAccess policy and attach the role to EC2 instance.
Steps to create EC2 instance using Ansible:

cd ~
mkdir playbooks
sudo ansible-playbook create_ec2.yml
Fix the warnings by executing below command
That's it!! That is how you create a new EC2 instance using Ansible.
