Vigimétéo - Connected Objects Management

Vigimétéo is an innovative web platform dedicated to real-time visualization of meteorological data from connected sensors. This project allows any user to consult updated weather information while providing a complete administration area to manage sensors, users, and categories.

Description

Vigimétéo is a tool that is both useful and accessible in the face of current climate challenges. Using an architecture combining React for the front-end and Vert.x for the back-end, the system relies on a PostgreSQL database centralizing measurements collected by weather stations. The interface allows for both intuitive consultation for the general public and complete management for administrators via a secured dashboard.

Features

Consult real-time meteorological data (fake data for now, not yet connected with an API)
IoT Device Management with the ability to set alerts for extreme data values
User Management: add, delete, and modify users
Category Management: manage device types
Responsive Interface (Mobile & Desktop)
Secure Authentication with JWT
Multi-language Support (i18n): Interface available in French and English

Usage (Docker - Cloud Deployment)

This application has been containerized to meet the requirements of the Cloud Computing course (Dev Web Ing1).

Prerequisites

Required OS: Linux (Ubuntu/Debian) with docker and docker-compose configured.
Required Resources: Internet connection to download base Docker images (nginx, node, maven, eclipse-temurin, postgres).

Services / Containers

The architecture is split into 3 distinct services via docker-compose.yaml:

vigimeteo_frontend: Image built via a multi-stage Dockerfile (Node.js to compile the Vite application, then Alpine Nginx to serve static files). This service listens on public port 5000.
vigimeteo_backend: Image built via a multi-stage Dockerfile (Maven to compile the JAR, then JRE 17 for execution). Runs the Vert.x API and communicates on public port 8888.
vigimeteo_db: Official postgres:15-alpine image.

Virtual Networks and Named Volumes

Network: vigimeteo_net (Bridge) allows frontend, backend, and DB containers to communicate securely in isolation from the rest of the system.
Volume: The persistent volume vigimeteo_data is mounted on the /var/lib/postgresql/data directory of the DB container. It ensures data persistence, guaranteeing that weather data and user accounts are not lost when restarting or rebuilding the containers.

Container Configuration

Environment Variables: The Vert.x backend dynamically reads PostgreSQL credentials (e.g., DB_HOST, DB_PASSWORD) provided via environment variables in the docker-compose.yaml file.
DB Initialization: The PostgreSQL container automatically synchronizes the sql/init_db.sql file in its /docker-entrypoint-initdb.d/init.sql directory for automatic population upon first initialization.
Restart Policy: All containers include the restart: always policy to restart automatically in case of failure.

How to Run the Application

Prepare the application: Run ./prepare-app.sh. This script initiates docker-compose build to create/download the images.
Launch the application: Run ./start-app.sh. Access the web application via your browser at http://localhost:5000. You can log into the administration interface using the email admin.a@gmail.com and password azertyuiop. You can also use the complexe@gmail.com and password azertyuiop to try different role.
Pause the application: Run ./stop-app.sh. This script stops the containers gracefully without resetting their state or destroying the virtual network.
Remove the application: Run ./remove-app.sh. This removes all containers, networks, local images, and named volumes, erasing all traces of the deployed application.

AI Usage (Cloud Computing Course)

AI Agent used: Google Gemini
AI's Role:
- Verification and optimization of the DockerCompose file
- Implementation of the English/French internationalization (i18n) system.
- Upgrade of the README for technical and overall the project structure
