-# Docker Web Application
-
-## Overview
-This is a Dockerized web application consisting of two services:
-- **Web Service:** A simple Python Flask application serving HTTP endpoints.
-- **Database Service:** A MySQL 8.0 database that stores its data in a persistent volume.
-
-The web service demonstrates basic functionality and includes an endpoint (`/dbtest`) to test connectivity with the database service.
-
-## Deployment Requirements
-- **Docker:** Ensure Docker is installed and running.
-- **Docker Compose:** Version 3.8 or later is required to run the multi-container application.
-
-## Application Architecture
-- **Virtual Network:**  
-  A custom Docker network `app-network` is used to allow seamless communication between containers.
-  
-- **Named Volume:**  
-  A persistent volume `db_data` is defined to store MySQL database data, ensuring data persistence between container restarts.
-
-## Container Configurations
-- **Web Service Container:**
-  - **Image:** Custom built from the provided `Dockerfile`.
-  - **Port:** Exposes port `5000`.
-  - **Environment Variables:** Set for database connectivity (e.g., `MYSQL_HOST`, `MYSQL_USER`, `MYSQL_PASSWORD`, `MYSQL_DATABASE`).
-  - **Restart Policy:** Configured to always restart on failure.
-  
-- **Database Service Container:**
-  - **Image:** Official `mysql:8.0` image.
-  - **Ports:** Exposes port `3306`.
-  - **Environment Variables:** Defines `MYSQL_ROOT_PASSWORD` and `MYSQL_DATABASE` for initial configuration.
-  - **Volume:** Uses named volume `db_data` for data persistence.
-  - **Restart Policy:** Configured to always restart on failure.
-
-## Used Containers
-- **web:** The Flask-based web server.
-- **db:** The MySQL database server.
-
-## How to Use the Application
-
-1. **Prepare the Application:**  
-   Run the following command to build images and create required networks/volumes:
-   ```bash
-   ./prepare-app.sh
-
-2. **Start the Application:** 
-    Launch the containers with:
-        ./start-app.sh
-    You should see a message:
-        Running app ...
-        The app is available at http://localhost:5000
-
-3. **Interact with the Application:**
-
-    • Open your web browser and go to http://localhost:5000 to view the home page.
-    • Visit http://localhost:5000/status for the application status.
-    • Visit http://localhost:5000/dbtest to test the database connectivity.
-
-4. **Stop the Application:**
-    To stop all running services without removing their state:
-        ./stop-app.sh
-
-5. **Remove the Application:**
-    When you want to completely remove all containers, networks, and volumes:
-        ./remove-app.sh
