## Overview
This guide provides comprehensive instructions for deploying the Crawlful Hub system to production environments.

## Prerequisites

### Software Requirements
- Docker 20.10+
- Kubernetes 1.20+
- kubectl 1.20+
- Helm 3.0+
- AWS CLI 2.0+ (for AWS deployment)

### Infrastructure Requirements
- At least 3 nodes with 4 vCPU and 8GB RAM each
- 100GB storage for MySQL
- 10GB storage for Redis
- Load balancer with SSL certificate

## Deployment Options

### Option 1: Docker Compose (Development/Testing)
\`\`\`bash
# Start all services
docker-compose up -d

# View logs
docker-compose logs -f

# Stop all services
docker-compose down
\`\`\`

### Option 2: Kubernetes (Production)
\`\`\`bash
# Deploy to Kubernetes
./scripts/deploy.sh production us-east-1

# Check deployment status
kubectl get pods -n crawlful-hub

# View logs
kubectl logs -f deployment/crawlful-hub-server -n crawlful-hub
\`\`\`

### Option 3: AWS EKS (Production)
\`\`\`bash
# Create EKS cluster
eksctl create cluster --name crawlful-hub --region us-east-1

# Deploy to EKS
kubectl apply -f k8s/

# Configure Load Balancer
kubectl apply -f k8s/ingress.yaml
\`\`\`

## Configuration

### Environment Variables
Create a \`.env\` file with the following variables:

\`\`\`bash
# Database
DB_HOST=mysql.crawlful.internal
DB_PORT=3306
DB_USER=crawlful
DB_PASSWORD=your_password
DB_NAME=crawlful_hub

# Redis
REDIS_HOST=redis.crawlful.internal
REDIS_PORT=6379

# JWT
JWT_SECRET=your_jwt_secret

# Application
NODE_ENV=production
PORT=3000
WS_PORT=8085
\`\`\`

### Secrets Management
For production, use Kubernetes secrets:

\`\`\`bash
# Create database secret
kubectl create secret generic db-secret \\
  --from-literal=host=mysql.crawlful.internal \\
  --from-literal=password=your_password \\
  -n crawlful-hub

# Create JWT secret
kubectl create secret generic jwt-secret \\
  --from-literal=secret=your_jwt_secret \\
  -n crawlful-hub
\`\`\`

## Monitoring and Logging

### Prometheus Metrics
Access Prometheus at \`http://your-domain:9090\`

### Grafana Dashboards
Access Grafana at \`http://your-domain:3001\`
- Default credentials: admin/admin

### CloudWatch Logs
For AWS deployment, logs are automatically sent to CloudWatch.

## Backup and Recovery

### Database Backup
\`\`\`bash
# Create backup
kubectl exec -it \$(kubectl get pods -n crawlful-hub -l app=mysql -o jsonpath='{.items[0].metadata.name}') -n crawlful-hub -- \\
  mysqldump -u root -p crawlful_hub > backup.sql

# Restore backup
kubectl exec -i \$(kubectl get pods -n crawlful-hub -l app=mysql -o jsonpath='{.items[0].metadata.name}') -n crawlful-hub -- \\
  mysql -u root -p crawlful_hub < backup.sql
\`\`\`

### Redis Backup
\`\`\`bash
# Create backup
kubectl exec -it \$(kubectl get pods -n crawlful-hub -l app=redis -o jsonpath='{.items[0].metadata.name}') -n crawlful-hub -- \\
  redis-cli SAVE

# Copy RDB file
kubectl cp crawlful-hub/redis-pod:/data/dump.rdb ./redis-backup.rdb
\`\`\`

## Troubleshooting

### Common Issues

1. **Pods not starting**
   \`\`\`bash
   kubectl describe pod <pod-name> -n crawlful-hub
   \`\`\`

2. **Service not accessible**
   \`\`\`bash
   kubectl get svc -n crawlful-hub
   kubectl get ingress -n crawlful-hub
   \`\`\`

3. **Database connection issues**
   \`\`\`bash
   kubectl logs -f deployment/crawlful-hub-server -n crawlful-hub | grep -i database
   \`\`\`

### Health Checks
\`\`\`bash
# Check overall health
curl http://api.crawlful.com/health

# Check database health
curl http://api.crawlful.com/health/database

# Check Redis health
curl http://api.crawlful.com/health/redis
\`\`\`

## Rollback Procedure

If deployment fails, use the rollback script:

\`\`\`bash
./scripts/rollback.sh production
\`\`\`

## Security Considerations

1. **Network Security**
   - Use network policies to restrict pod communication
   - Implement service mesh for mTLS
   - Configure firewall rules

2. **Secrets Management**
   - Use Kubernetes secrets or external secret managers
   - Rotate secrets regularly
   - Never commit secrets to version control

3. **Access Control**
   - Implement RBAC for Kubernetes
   - Use least privilege principle
   - Enable audit logging

## Performance Tuning

### Database Optimization
- Configure connection pooling
- Enable query cache
- Optimize indexes
- Monitor slow queries

### Redis Optimization
- Configure memory limits
- Use appropriate eviction policy
- Enable persistence
- Monitor memory usage

### Application Optimization
- Enable gzip compression
- Configure caching strategies
- Optimize bundle size
- Implement CDN for static assets

## Maintenance

### Regular Tasks
- Daily: Monitor system health and logs
- Weekly: Review performance metrics
- Monthly: Apply security updates
- Quarterly: Review and update documentation

### Update Procedure
\`\`\`bash
# Pull latest changes
git pull origin main

# Build new images
docker build -t crawlful/hub-server:latest ./server

# Deploy new version
kubectl set image deployment/crawlful-hub-server server=crawlful/hub-server:latest -n crawlful-hub

# Verify deployment
kubectl rollout status deployment/crawlful-hub-server -n crawlful-hub
\`\`\`
