## 🚀 How to Deploy

### Prerequisites
**Install Docker first:**
```bash
# Ubuntu/Debian
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo usermod -aG docker $USER
# Log out and back in
```

### Deploy
```bash
cd /srv/quality_recticel
./deploy.sh
```

That's it! Your application will be available at http://localhost:8781

## 📋 Usage Examples

### Basic Operations
```bash
# Start services
docker compose up -d

# View logs
docker compose logs -f

# Stop services
docker compose down

# Restart
docker compose restart

# Check status
docker compose ps
```

### Using Makefile (Recommended)
```bash
make install     # First-time setup
make up          # Start services
make down        # Stop services
make logs        # View logs
make logs-web    # View only web logs
make logs-db     # View only database logs
make shell       # Access app container
make shell-db    # Access database console
make backup-db   # Backup database
make status      # Show service status
make help        # Show all commands
```

### Advanced Operations
```bash
# Rebuild after code changes
docker compose up -d --build web

# Access application shell
docker compose exec web bash

# Run database commands
docker compose exec db mariadb -u trasabilitate -p trasabilitate

# View resource usage
docker stats recticel-app recticel-db

# Complete reset (removes all data!)
docker compose down -v
```

## 🗂️ Data Storage

### Persistent Data
- **Database**: Stored in Docker volume `mariadb_data`
- **Logs**: Mounted to `./logs` directory
- **Config**: Mounted to `./instance` directory

### Backup Database
```bash
docker compose exec -T db mariadb-dump -u trasabilitate -pInitial01! trasabilitate > backup.sql
```

### Restore Database
```bash
docker compose exec -T db mariadb -u trasabilitate -pInitial01! trasabilitate < backup.sql
```

## 🔐 Default Credentials

### Application
- URL: http://localhost:8781
- Username: `superadmin`
- Password: `superadmin123`
- **⚠️ Change after first login!**

### Database
- Host: `localhost:3306` (from host) or `db:3306` (from containers)
- Database: `trasabilitate`
- User: `trasabilitate`
- Password: `Initial01!`
- Root Password: Set in `.env` file

## 🎓 Quick Reference

### Environment Variables (.env)
```env
MYSQL_ROOT_PASSWORD=rootpassword    # MariaDB root password
DB_PORT=3306                        # Database port (external)
APP_PORT=8781                       # Application port
INIT_DB=true                        # Run DB initialization
SEED_DB=true                        # Seed superadmin user
```

### Important Ports
- `8781`: Flask application (web interface)
- `3306`: MariaDB database (optional external access)

### Log Locations
- Application logs: `./logs/access.log` and `./logs/error.log`
- Container logs: `docker compose logs`

## 🔧 Troubleshooting

### Can't connect to application
```bash
# Check if services are running
docker compose ps

# Check web logs
docker compose logs web

# Verify port not in use
netstat -tuln | grep 8781
```

### Database connection issues
```bash
# Check database health
docker compose exec db healthcheck.sh --connect

# View database logs
docker compose logs db

# Test database connection
docker compose exec web python3 -c "import mariadb; print('OK')"
```

### Port already in use
Edit `.env` file:
```env
APP_PORT=8782  # Change to available port
DB_PORT=3307   # Change if needed
```

### Start completely fresh
```bash
docker compose down -v
rm -rf logs/* instance/external_server.conf
./deploy.sh
```
