# Containerization Implementation Summary
## Problem Resolved
The error "No Dockerfiles nor Kubernetes YAML found in /" has been resolved by creating comprehensive containerization files for the OCR PDF MCP Server project.
## Files Created
### Docker Files
1. **`Dockerfile`** - Standard production Docker image
- Based on Python 3.11-slim
- Includes Tesseract OCR and dependencies
- Non-root user for security
- Health checks included
2. **`Dockerfile.prod`** - Multi-stage production build
- Optimized for smaller image size
- Separate build and runtime stages
- Enhanced security configurations
3. **`docker-compose.yml`** - Docker Compose configuration
- Service definitions
- Volume mounts for PDFs and logs
- Health checks and restart policies
- Optional Redis service (commented)
4. **`.dockerignore`** - Updated Docker ignore patterns
- Excludes development files
- Optimizes build context
### Kubernetes Files (k8s/)
1. **`deployment.yaml`** - Kubernetes deployment and service
- 2 replica pods by default
- Resource limits and requests
- Liveness and readiness probes
- Service with ClusterIP
2. **`ingress.yaml`** - Ingress configuration
- NGINX ingress controller support
- TLS/SSL certificate management
- CORS headers configuration
3. **`configmap.yaml`** - Configuration management
- Environment variables
- Secrets for sensitive data
- Optional persistent volume claim
4. **`hpa.yaml`** - Horizontal Pod Autoscaler
- Auto-scaling based on CPU/memory
- Min 2, max 10 replicas
- 70% CPU, 80% memory thresholds
5. **`README.md`** - Kubernetes deployment guide
- Step-by-step deployment instructions
- Management commands
- Troubleshooting tips
### Deployment Scripts
1. **`scripts/docker-deploy.sh`** - Linux/macOS Docker deployment
- Automated build and deployment
- Container management commands
- Status monitoring
2. **`scripts/docker-deploy.bat`** - Windows Docker deployment
- Windows-compatible batch script
- Same functionality as shell script
- Color-coded output
3. **`scripts/k8s-deploy.sh`** - Kubernetes deployment script
- Full Kubernetes deployment automation
- Image building and pushing
- Cluster management
## Usage Instructions
### Docker Deployment
```bash
# Quick start
docker-compose up -d
# Advanced deployment (Linux/macOS)
./scripts/docker-deploy.sh run
# Advanced deployment (Windows)
scripts\docker-deploy.bat run
```
### Kubernetes Deployment
```bash
# Full deployment
./scripts/k8s-deploy.sh deploy
# Manual deployment
kubectl apply -f k8s/ -n ocr-pdf-mcp
```
### Available Commands
#### Docker Script Commands
- `build` - Build Docker image only
- `run` - Build and run container (default)
- `start` - Start container (assumes image exists)
- `stop` - Stop running container
- `logs` - Show container logs
- `clean` - Stop container and remove image
- `status` - Show container status
#### Kubernetes Script Commands
- `build` - Build and push Docker image only
- `deploy` - Full deployment (build, push, deploy)
- `update` - Update existing deployment with new image
- `status` - Show deployment status
- `logs` - Show application logs
- `forward` - Port forward to local machine
- `scale [n]` - Scale deployment to n replicas
- `restart` - Restart deployment
- `cleanup` - Remove all resources
## Production Features
### Security
- Non-root user in containers
- Resource limits and requests
- Health checks and probes
- TLS/SSL support in ingress
### Scalability
- Horizontal Pod Autoscaler
- Multi-replica deployments
- Load balancing via services
- Configurable resource limits
### Monitoring
- Health check endpoints
- Container logs aggregation
- Pod status monitoring
- Service discovery
### Storage
- Persistent volume support
- Volume mounts for PDFs
- Log storage persistence
- ConfigMap for configuration
## Environment Variables
- `LOG_LEVEL` - Logging level (INFO, DEBUG, ERROR)
- `CORS_ORIGINS` - CORS allowed origins
- `MCP_SERVER_NAME` - Server identification
- `DOCKER_REGISTRY` - Docker registry URL (for K8s)
## Next Steps
1. Customize ingress domain in `k8s/ingress.yaml`
2. Configure persistent storage if needed
3. Set up Docker registry for Kubernetes deployments
4. Configure monitoring and logging solutions
5. Set up CI/CD pipelines for automated deployments
The OCR PDF MCP Server is now ready for containerized deployment in both Docker and Kubernetes environments.
