In this article, I will demonstrate how to provision EC2 instance using ANSIBLE and how do set up a more agile environment using the DYNAMIC INVENTORY.

→Pre-requisites:

— >RedHat Ansible downloaded and configured in the local system.

Do check out my previous article for Ansible👇👇:

~Problem Statement:

♦️ Deploy Web Server on AWS through ANSIBLE!

🔹 Provision EC2 instance through ansible.

🔹 Retrieve the IP Address of instance using the dynamic inventory concept.

🔹 Configure the webserver through ansible!

• As Ansible is built on top of python, a Python Software Development Kit (SDK) is required that enables the configuration of AWS services. The package is an object-oriented API named boto3.

pip3 install boto3   //assuming python3 is installed

→STEP-1)

• In the first step, I provisioned an ec2 instance with this playbook.
• Here, the RedHat system itself calls the API for configuration on AWS, and this procedure is done on the local machine that’s why the host is supposed to be localhost.
• For authentication to the AWS account, create one IAM user that has less privileged than the root account. The AWS_ACCESS_KEY and AWS_SECRET key are passed explicitly through an Ansible vault named secret.yml
