Terraform-Ansible-AWS-EC2-Setup

A comprehensive guide and code repository demonstrating the automated provisioning and configuration of an AWS EC2 instance with Nginx using Terraform for infrastructure management and Ansible for configuration. Simplify your infrastructure deployment process with this easy-to-follow project.

Provisioning Infrastructure using Terraform and Ansible

Overview

This project demonstrates the provisioning and configuration of infrastructure resources on AWS using Terraform for resource creation and Ansible for configuration management. The goal is to create an EC2 instance and install Nginx on it.

Prerequisites

Ubuntu machine with Terraform and Ansible installed
AWS account with appropriate permissions
AWS CLI configured on the local machine

Steps

AWS Key Pair
- Login to the AWS console.
- Generate a key pair and download it in PEM format.

Terraform Configuration

Write the main.tf file with the following specifications:

locals {
  vpc_id           = "vpc-090d44ff9674390bf"
  subnet_id        = "subnet-00783f62f7d584e6b"
  ssh_user         = "ubuntu"
  key_name         = "ec2-terra-key"
  private_key_path = "~/Downloads/ec2-terra-key.pem"
}

provider "aws" {
  region = "us-east-1"
}

resource "aws_security_group" "nginx" {
  # ... (security group configuration)
}

resource "aws_instance" "nginx" {
  # ... (instance configuration)
}

output "nginx_ip" {
  value = aws_instance.nginx.public_ip
}

Ansible Configuration

Write the nginx.yaml Ansible playbook to install Nginx on the Ubuntu instance:

---
- name: Configure EC2 instances
  hosts: all
  become: true

  tasks:
    - name: Update package cache
      apt:
        update_cache: yes

    - name: Install nginx
      apt:
        name: nginx
        state: present

Create an ansible.cfg file with the following content:
```
[defaults]
host_key_checking = False
```

Execution
- Run the following commands in the terminal:
```
terraform init
terraform apply
```
- After Terraform applies successfully, check the public IP of the EC2 instance.
- Run the Ansible playbook using the following command:
```
ansible-playbook -i <EC2_PUBLIC_IP>, --private-key ~/Downloads/ec2-terra-key.pem nginx.yaml
```
Verification
- Access the Nginx welcome page by navigating to the EC2 instance's public IP in a web browser.

Outputs

The public IP of the provisioned EC2 instance is available as an output.

Nginx Public IP: <EC2_PUBLIC_IP>

Note

Ensure that the specified key pair, VPC ID, subnet ID, and AMI ID are correct for your AWS environment.
Verify that the security group allows SSH (port 22) and HTTP (port 80) traffic.

Clean-Up

Run the following command to destroy the provisioned resources:
```
terraform destroy
```

Feel free to customize the provided Terraform and Ansible scripts according to your specific requirements. For more detailed information, refer to the official documentation of Terraform and Ansible.
