mvn spring-boot:run

Access APIs at http://localhost:8081 🌐

Option 2: Full DevOps Deployment

Prerequisites:

Jenkins with Docker, JDK, Maven plugins

Docker Hub account

Minikube (or cloud Kubernetes)

Steps:

Jenkins Pipeline will automatically:

Build → Test → Dockerize → Push to Docker Hub → Deploy to Kubernetes

kubectl apply -f k8s/mysql-pv.yaml
kubectl apply -f k8s/mysql-deployment.yaml
kubectl apply -f k8s/deployment.yaml
kubectl apply -f k8s/service.yaml

Access the live app:

kubectl get services
# Open http://<EXTERNAL-IP>:80
