+# TaskFlow - Docker Deployment Guide
+
+This guide explains how to deploy TaskFlow using Docker with a separate PostgreSQL database.
+
+## Prerequisites
+
+- Docker Engine 20.10 or later
+- Docker Compose 2.0 or later
+- At least 2GB of available RAM
+- 10GB of available disk space
+
+## Quick Start
+
+### 1. Environment Configuration
+
+Create a `.env` file in the root directory:
+
+```bash
+cp .env.example .env
+```
+
+Edit the `.env` file with your configuration:
+
+```env
+# Application Configuration
+NODE_ENV=production
+PORT=5000
+
+# Database Configuration
+POSTGRES_USER=taskflow
+POSTGRES_PASSWORD=your_secure_password_here
+POSTGRES_DB=taskflow
+POSTGRES_PORT=5432
+
+# Database URL (update with your credentials)
+DATABASE_URL=postgresql://taskflow:your_secure_password_here@postgres:5432/taskflow
+
+# Application Port (external mapping)
+APP_PORT=5000
+```
+
+**Important:** Change the `POSTGRES_PASSWORD` to a secure password!
+
+### 2. Start the Application
+
+```bash
+# Build and start all services
+docker-compose up -d
+
+# View logs
+docker-compose logs -f
+
+# Check service status
+docker-compose ps
+```
+
+The application will be available at `http://localhost:5000`
+
+### 3. Stop the Application
+
+```bash
+# Stop services
+docker-compose down
+
+# Stop and remove volumes (WARNING: This will delete all data!)
+docker-compose down -v
+```
+
+## Production Deployment
+
+### Using Docker Stack (Swarm Mode)
+
+1. **Initialize Docker Swarm** (if not already done):
+
+```bash
+docker swarm init
+```
+
+2. **Create a production `.env` file**:
+
+```bash
+# Set secure credentials
+export POSTGRES_PASSWORD="your_very_secure_password"
+export POSTGRES_USER="taskflow"
+export POSTGRES_DB="taskflow"
+```
+
+3. **Deploy the stack**:
+
+```bash
+docker stack deploy -c docker-compose.yml taskflow
+```
+
+4. **Check stack status**:
+
+```bash
+docker stack services taskflow
+docker stack ps taskflow
+```
+
+5. **View logs**:
+
+```bash
+docker service logs taskflow_app
+docker service logs taskflow_postgres
+```
+
+6. **Remove the stack**:
+
+```bash
+docker stack rm taskflow
+```
+
+### Using External PostgreSQL Database
+
+If you want to use an external PostgreSQL instance instead of the containerized one:
+
+1. **Update `.env` file**:
+
+```env
+DATABASE_URL=postgresql://username:password@your-db-host:5432/your-db-name
+```
+
+2. **Modify `docker-compose.yml`** to remove the postgres service:
+
+```yaml
+version: '3.8'
+
+services:
+  app:
+    build:
+      context: .
+      dockerfile: Dockerfile
+      target: production
+    container_name: taskflow-app
+    restart: unless-stopped
+    environment:
+      NODE_ENV: production
+      DATABASE_URL: ${DATABASE_URL}
+      PORT: 5000
+    ports:
+      - "${APP_PORT:-5000}:5000"
+```
+
+3. **Start only the app service**:
+
+```bash
+docker-compose up app -d
+```
+
+## Database Management
+
+### Backup Database
+
+```bash
+# Create backup
+docker exec taskflow-db pg_dump -U taskflow taskflow > backup_$(date +%Y%m%d_%H%M%S).sql
+
+# Or using docker-compose
+docker-compose exec postgres pg_dump -U taskflow taskflow > backup.sql
+```
+
+### Restore Database
+
+```bash
+# Restore from backup
+docker exec -i taskflow-db psql -U taskflow taskflow < backup.sql
+
+# Or using docker-compose
+docker-compose exec -T postgres psql -U taskflow taskflow < backup.sql
+```
+
+### Access Database
+
+```bash
+# Connect to PostgreSQL shell
+docker exec -it taskflow-db psql -U taskflow -d taskflow
+
+# Or using docker-compose
+docker-compose exec postgres psql -U taskflow -d taskflow
+```
+
+### Run Migrations
+
+The application automatically runs database migrations on startup. To manually trigger migrations:
+
+```bash
+# Inside the container
+docker exec taskflow-app npm run db:push
+
+# Or rebuild and restart
+docker-compose up --build -d
+```
+
+## Monitoring and Maintenance
+
+### Health Checks
+
+Both services have health checks configured:
+
+- **App**: `http://localhost:5000/api/health`
+- **Database**: Automatic PostgreSQL health check
+
+Check health status:
+
+```bash
+docker-compose ps
+```
+
+### View Logs
+
+```bash
+# All services
+docker-compose logs -f
+
+# Specific service
+docker-compose logs -f app
+docker-compose logs -f postgres
+
+# Last 100 lines
+docker-compose logs --tail=100 app
+```
+
+### Update Application
+
+```bash
+# Pull latest changes
+git pull
+
+# Rebuild and restart
+docker-compose up --build -d
+
+# Remove old images
+docker image prune -f
+```
+
+## Troubleshooting
+
+### Application won't start
+
+1. Check logs: `docker-compose logs app`
+2. Verify DATABASE_URL is correct
+3. Ensure PostgreSQL is healthy: `docker-compose ps`
+
+### Database connection errors
+
+1. Verify PostgreSQL is running: `docker-compose ps postgres`
+2. Check connection string in `.env`
+3. Ensure network connectivity: `docker network inspect taskflow_taskflow-network`
+
+### Port already in use
+
+Change the `APP_PORT` in `.env` file:
+
+```env
+APP_PORT=8080
+```
+
+Then restart: `docker-compose up -d`
+
+### Out of disk space
+
+```bash
+# Remove unused images
+docker image prune -a
+
+# Remove unused volumes
+docker volume prune
+
+# Remove unused networks
+docker network prune
+```
+
+## Security Best Practices
+
+1. **Change default passwords** in `.env` file
+2. **Use environment variables** for sensitive data
+3. **Enable SSL/TLS** for production databases
+4. **Restrict network access** using firewall rules
+5. **Regular backups** of database
+6. **Keep Docker images updated** regularly
+7. **Use secrets management** for production (Docker Secrets, Vault, etc.)
+
+## Performance Tuning
+
+### PostgreSQL
+
+Edit `docker-compose.yml` to add PostgreSQL configuration:
+
+```yaml
+postgres:
+  command: postgres -c max_connections=200 -c shared_buffers=256MB
+```
+
+### Application
+
+Scale the application service:
+
+```bash
+docker-compose up -d --scale app=3
+```
+
+## Support
+
+For issues and questions:
+- Check logs first: `docker-compose logs`
+- Review this guide
+- Check Docker and PostgreSQL documentation
