+# Visitor Counter Application
+
+## Description of the Application
+This application is designed to count the number of visits to a webpage. It utilizes Flask for the backend, Apache for serving static web content, and Redis for storing visitor counts.
+
+## List of Containers Used
+
+- **Backend Container**: Built using Flask, this container handles API requests and updates visitor counts in Redis.
+- **Web Container**: Built using Apache, this container serves static HTML content.
+- **Redis Container**: Uses the official Redis image to store visitor counts persistently.
+
+## List of Kubernetes Objects
+
+- **Deployments**:
+  - **Backend Deployment**: Manages the backend Flask application.
+  - **Web Deployment**: Manages the web Apache server.
+- **Services**:
+  - **Backend Service**: Exposes the backend application on a specific port.
+  - **Web Service**: Exposes the web server on a specific port.
+  - **Redis Service**: Provides access to the Redis database.
+- **StatefulSet**:
+  - **Redis StatefulSet**: Ensures persistent storage for Redis data.
+- **PersistentVolumeClaim (PVC)** and **PersistentVolume (PV)**:
+  - Used for providing persistent storage to Redis.
+
+## Virtual Networks and Named Volumes
+
+- **Virtual Networks**: Kubernetes automatically manages pod-to-pod communication within a cluster.
+- **Named Volumes**: Used for persistent storage in Redis, ensuring data is retained across pod restarts.
+
+## Container Configuration
+
+- **Backend Container**: Configured to listen on port 5000 and connect to Redis for storing visitor counts.
+- **Web Container**: Configured to serve static HTML content on port 80.
+- **Redis Container**: Configured to store data persistently using a PersistentVolumeClaim.
+
+## Instructions to Prepare, Run, Pause, and Delete the Application
+
+1. **Prepare the Application**:
+   Run the `prepare-app.sh` script to build Docker images and load them into Minikube.
+
+./prepare-app.sh
+
+
+2. **Run the Application**:
+Run the `start-app.sh` script to create all necessary Kubernetes objects and start the application.
+./start-app.sh
+
+
+3. **Pause the Application**:
+You can pause the application by scaling down deployments to zero replicas:
+
+kubectl scale deployment backend-deployment --replicas=0
+kubectl scale deployment web-deployment --replicas=0
+
+
+4. **Delete the Application**:
+Run the `stop-app.sh` script to delete all Kubernetes objects and stop the application.
+./stop-app.sh
+
+
+## Instructions to View the Application on the Web
+
+1. **Access the Web Service**:
+Use Minikube to access the web service:
+
+minikube service web-service --url
+
+This will output a URL that you can use to view the application in your web browser by ctrl+clicking on the link.
