• Pagination and advanced search
• Beautiful, responsive UI with gradients, dark/light mode, and custom modals
• Toast notifications for all actions, styled to match the app
• Internationalization (i18n): English, French, German, Spanish, Chinese, Hebrew (with language switcher)

Backend (Spring Boot)

• Java 17+, Gradle
• REST API for managing flight reservations
• Endpoints:
  • POST /tickets – Create a reservation
  • GET /tickets – List all reservations
  • GET /tickets/search – Search reservations (by departure, destination, flightNumber, status, kickoffTime)
  • PUT /tickets/{id} – Update a reservation
  • DELETE /tickets/{id} – Delete a reservation
• CORS enabled for local development
• See src/main/resources/application.properties for DB config

---

Frontend (React)

• See flight-frontend/README.md for full details
• Modern UI with Tailwind CSS, react-toastify, and i18n
• Kubernetes deployment uses an internal Nginx proxy:
  • All API calls use a relative path (/api).
  • Nginx proxies /api requests to the backend service (flight-backend:8080) inside the cluster.
  • See flight-frontend/nginx.conf for proxy config.

---

Setup & Local Development

1. Backend

./gradlew bootRun

Runs at http://localhost:8080

2. Frontend

cd flight-frontend
npm install
npm start

Runs at http://localhost:3000

---

Kubernetes & Docker Deployment

1. Build Docker Images

# In flight-frontend directory
# Make sure src/api.js uses API_BASE = '/api';
# Make sure nginx.conf is present as described in the docs

docker build -t flight-frontend:latest .
docker save flight-frontend:latest -o flight-frontend.tar
sudo ctr -n k8s.io images import flight-frontend.tar

# For backend, build and import similarly if needed

2. Deploy to k3s

kubectl apply -f k8s/postgres-deployment.yaml
kubectl apply -f k8s/backend-deployment.yaml
kubectl apply -f k8s/frontend-deployment.yaml

3. Accessing the App

• Use NodePort: http://<VM-IP>:<NodePort>
• Or use kubectl port-forward for local access:

  kubectl port-forward service/flight-frontend 8080:80
  # Then open http://localhost:8080 on the same machine where you run the command

---

Internationalization (i18n)

• Fully supports English, French, German, Spanish, Chinese, and Hebrew.
• All UI and notifications are translated.
• Easily extensible for more languages in flight-frontend/src/i18n.js.

---

Archiving and Copying the Project

To archive the entire project directory (from the VM):

cd /path/to/parent/of/flight-reservations
# Create a compressed archive
 tar czvf flight-reservations.tar.gz flight-reservations/
# Copy the archive to your local machine using scp:
scp user@vm-ip:/path/to/flight-reservations.tar.gz /local/path/
