Python Application with Nginx Load Balancer and MySQL Database

This project sets up a Python web application with an Nginx load balancer, running in Docker containers using Docker Compose.

Features

1. Python Web Application:

   • Route /:
     • Sets a cookie with the internal IP for 5 minutes.
     • Logs client IP, date, and time to a MySQL table (access_log).
     • Returns the server's internal IP to the browser.
   • Route /showcount:
     • Displays a global counter.

2. Nginx Load Balancer:

   • Routes traffic to the application containers (3 replicas).
   • Implements stickiness using cookies (users stick to the same server for 5 minutes).

3. MySQL Database:

   • Retains data and logs after container stops.

4. Scalability:

   • Includes a Bash script to scale the application up or down (e.g., to 5 replicas).

Requirements

• Docker and Docker Compose installed.

Setup

1. Clone the repository:

   git clone <repository-url>
   cd <repository-folder>
   
   

This document assumes a repository structure with the necessary files (e.g., Dockerfile, docker-compose.yml, nginx.conf, scale.sh) and provides a concise overview for users.
