# Production Deployment Guide

## Prerequisites

- Docker and Docker Compose
- Domain name (optional)
- SSL certificate (for HTTPS)

## Environment Setup

1. **Create environment file:**
   ```bash
   cp .env.example .env
   ```

2. **Configure production variables:**
   ```bash
   # Database
   POSTGRES_PASSWORD=your_secure_database_password_here
   JWT_SECRET=your_jwt_secret_here
   
   # API
   REACT_APP_API_URL=http://your-domain.com:3001
   
   # Security
   CORS_ORIGIN=https://your-domain.com
   ```

## Deployment

### Option 1: Docker Compose (Recommended)

```bash
# Production deployment
docker-compose -f docker-compose.prod.yml up -d

# Check status
docker-compose -f docker-compose.prod.yml ps

# View logs
docker-compose -f docker-compose.prod.yml logs -f
```

### Option 2: Individual Services

```bash
# Build production images
docker build -t merchantsofhope-backend:prod ./backend
docker build -t merchantsofhope-frontend:prod ./frontend

# Run database
docker run -d --name db \
  -e POSTGRES_PASSWORD=your_password \
  -v postgres_data:/var/lib/postgresql/data \
  postgres:15-alpine

# Run backend
docker run -d --name backend \
  -e DATABASE_URL=postgresql://user:pass@db:5432/db \
  -e JWT_SECRET=your_secret \
  -p 3001:3001 \
  merchantsofhope-backend:prod

# Run frontend
docker run -d --name frontend \
  -e REACT_APP_API_URL=http://backend:3001 \
  -p 80:80 \
  merchantsofhope-frontend:prod
```

## Health Checks

- Backend: `http://localhost:3001/api/health`
- Frontend: `http://localhost:80`
- Database: Check container logs

## Security Considerations

1. **Change default passwords**
2. **Use strong JWT secrets**
3. **Configure CORS properly**
4. **Set up SSL/TLS**
5. **Regular security updates**
6. **Monitor logs**

## Monitoring

```bash
# View application logs
docker-compose -f docker-compose.prod.yml logs -f

# Check resource usage
docker stats

# Database backup
docker exec merchantsofhope-supplyanddemandportal-database pg_dump -U user db > backup.sql
```

## Troubleshooting

1. **Database connection issues:**
   - Check POSTGRES_PASSWORD
   - Verify network connectivity
   - Check database logs

2. **Frontend not loading:**
   - Check REACT_APP_API_URL
   - Verify backend is running
   - Check nginx logs

3. **Authentication issues:**
   - Verify JWT_SECRET
   - Check token expiration
   - Review auth logs
