Clone the repository: + + ```bash + git clone + ``` + +2. Navigate to the project directory: + + ```bash + cd + ``` + +3. Create a folder named `uploads`: + + ```bash + mkdir uploads + ``` + +4. Set permissions for the `uploads` folder: + + ```bash + chmod 777 uploads + ``` + +5. Run the application using Docker Compose: + + ```bash + docker-compose up -d + ``` + +The application should be accessible at [http://localhost:8080](http://localhost:8080). + +## Configuration + +Modify the `docker-compose.yml` file to adjust environment variables, ports, or any other configurations as needed. + +## Additional Information + +- This project uses NGINX as a reverse proxy.
