-# PI Visualization Web Application on Kubernetes
-
-## Overview
-This project deploys a Python web application using Flask on a Kubernetes cluster. The application displays the first 300 digits of PI with an interactive visualization. The deployment includes a Namespace, Deployment, StatefulSet (with PersistentVolume and PersistentVolumeClaim), and Service.
-
-## Application Description
-- The web application visualizes PI digits at the root URL (`/`).
-- Each digit appears one at a time (every 0.5 seconds by default) with a unique color.
-- Users can control the animation (start, pause, reset) and adjust the speed.
-- The application uses one container image built from the Dockerfile provided.
-
-## Containers
-- **simple-web-app**: Runs the Python Flask application on port 5000.
-
-## Kubernetes Objects
-- **Namespace**: Isolates all the resources under `my-app`.
-- **Deployment**: Manages the stateless web application pods with 2 replicas for high availability.
-- **StatefulSet**: Manages stateful application pods that require persistent storage.
-- **PersistentVolume (PV)**: Provides persistent storage from the host (1GB).
-- **PersistentVolumeClaim (PVC)**: Claims the PV for storage.
-- **Service**: Exposes the web application externally via NodePort 30007.
-
-## Networking and Storage
-- The application uses Kubernetes networking to enable communication between pods.
-- The StatefulSet uses a volume claim template that binds to a PersistentVolume mounted at `/data`.
-
-## Container Configuration
-- The container is based on Python and includes Flask.
-- It exposes port 5000 to serve the web application.
-- Resource limits and readiness probes are configured for better stability.
-
-## How to Prepare, Run, Pause, and Delete the Application
-
-1. **Prepare the application:**
-   ```bash
-   ./prepare-app.sh
-   ```
-   This script builds the Docker image and creates the directory for persistent volume.
-
-2. **Start the application:**
-   ```bash
-   ./start-app.sh
-   ```
-   This script creates all necessary Kubernetes objects in the correct order.
-
-3. **Pause or delete the application:**
-   ```bash
-   ./stop-app.sh
-   ```
-   This script removes all Kubernetes objects created by `start-app.sh`.
-
-## Accessing the Application
-To access the application:
-
-1. Find the IP address of your Kubernetes node:
-   ```bash
-   kubectl get nodes -o wide
-   ```
-
-2. Access the application in your browser at:
-   ```
-   http://<NODE_IP>:30007
-   ```
-   Where `<NODE_IP>` is the IP address of any of your Kubernetes nodes.
-
-## Troubleshooting
-If you encounter issues:
-
-1. Check pod status:
-   ```bash
-   kubectl get pods -n my-app
-   ```
-
-2. View pod logs:
-   ```bash
-   kubectl logs <pod-name> -n my-app
-   ```
-
-3. Check service status:
-   ```bash
-   kubectl get svc -n my-app
-   ```
