Features

• Scalable Backend: Built using Flask with REST APIs for e-commerce functionalities.
• Interactive Frontend: HTML/CSS/JavaScript-based user interface.
• Containerization: Application packaged using Docker.
• CI/CD Pipelines: Integrated pipelines for automated testing, deployment, and scaling.
• Infrastructure as Code: Automated infrastructure provisioning and configuration.
• Modular Deployment: Separate branches for AWS, Jenkins, Ansible, and Terraform implementations.

Branches and Implementation

1. AWS Branch

Purpose: Deploy the E-Commerce Application on AWS infrastructure.

Key Features:

• Provisioning EC2 instances using AWS CLI or AWS SDK.
• Load Balancing using AWS Elastic Load Balancer (ELB).
• Auto-scaling with AWS Auto Scaling Groups.
• S3 for static content hosting.
• RDS for database management.

Deployment Steps:

1. Clone the aws-branch.
2. Configure AWS CLI credentials.
3. Execute deploy.sh to provision and deploy the application.

# Example AWS CLI setup
aws configure

# Deploy script
bash deploy.sh

2. Deploy Branch - Jenkins

Purpose: Automate application deployment with Jenkins CI/CD pipeline.

Key Features:

• Build, Test, and Deploy stages in the Jenkins pipeline.
• Integration with Docker for containerized deployment.
• Use of Jenkinsfile to define the pipeline as code.
• Trigger deployments on code pushes.

Deployment Steps:

1. Clone the deploy-branch.
2. Install and configure Jenkins.
3. Add a new pipeline in Jenkins with this repository.
4. Run the Jenkins pipeline.

Jenkinsfile Example:

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                sh 'docker build -t ecommerce-app:latest .'
            }
        }
        stage('Test') {
            steps {
                sh 'pytest tests/'
            }
        }
        stage('Deploy') {
            steps {
                sh 'docker run -d -p 80:80 ecommerce-app:latest'
            }
        }
    }
}

3. Ansible Branch

Purpose: Automate server configuration and application deployment using Ansible.

Key Features:

• Ansible playbooks for server provisioning and app deployment.
• Configures web server (Nginx/Apache) and application dependencies.
• Supports idempotent and automated deployments.

Deployment Steps:

1. Clone the ansible-branch.
2. Configure the inventory file with your server IPs.
3. Run the Ansible playbook:

ansible-playbook -i inventory deploy.yml

Sample Playbook:

- name: Deploy E-Commerce App
  hosts: all
  tasks:
    - name: Install dependencies
      apt:
        name: ['docker.io', 'python3-pip']
        state: present

    - name: Run the application
      command: docker run -d -p 80:80 ecommerce-app:latest

4. Terraform Branch

Purpose: Provision and manage infrastructure using Terraform.

Key Features:

• Provision EC2 instances, RDS databases, and S3 buckets.
• Infrastructure defined as code for easy management and versioning.
• Supports scaling and resource monitoring.

Deployment Steps:

1. Clone the terraform-branch.
2. Initialize and apply the Terraform configuration:

terraform init
terraform apply

Sample Terraform Script:

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

resource "aws_instance" "ecommerce_server" {
  ami           = "ami-0abcdef1234567890"
  instance_type = "t2.micro"

  tags = {
    Name = "E-Commerce App Server"
  }
}
