FLASK APP ON MINIKUBE:

This project demonstrates how to deploy a simple Flask web application in a Kubernetes cluster using Minikube. The app is containerized using Docker and deployed with Kubernetes manifests.

1. Prerequisites Before you begin, ensure that you have the following installed on your machine:

Docker: https://docs.docker.com/get-docker/

Minikube: https://minikube.sigs.k8s.io/docs/start/

kubectl: https://kubernetes.io/docs/tasks/tools/install-kubectl/

Git: https://git-scm.com/book/en/v2/Getting-Started-Installing-Git

2. Build the Docker Image Build the Docker image from the Dockerfile

         docker build -t flask-app:latest .
   

3. Run the Flask App Locally If you want to test the app locally before deploying it to Minikube, run it using Docker:

        docker run -p 5000:5000 flask-app 
   

4. Minikube Deployment

Start Minikube to set up a local Kubernetes cluster:

 minikube start

5. Apply Kubernetes Manifests

Deploy the Flask app to Minikube using the Kubernetes manifests (deployment.yaml and service.yaml):

  kubectl apply -f deployment.yaml
  kubectl apply -f service.yaml

6. Access the Flask App via Minikube

   Once the deployment is successful, access the app through Minikube’s exposed NodePort:

      minikube service flask-app-service
   

This will open the app in your default browser at the Minikube IP.
