🚀 How to Deploy

Prerequisites

Install Docker first:

# 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

cd /srv/quality_recticel
./deploy.sh

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

📋 Usage Examples

Basic Operations

# 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)

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

# 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

docker compose exec -T db mariadb-dump -u trasabilitate -pInitial01! trasabilitate > backup.sql

Restore Database

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)

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

# 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

# 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:

APP_PORT=8782  # Change to available port
DB_PORT=3307   # Change if needed

Start completely fresh

docker compose down -v
rm -rf logs/* instance/external_server.conf
./deploy.sh
