- **Python 3.10+** (for CLI and development)
- **2GB+ RAM, 10GB+ disk space**
- **Ports**: 53, 80, 443, 3000, 51820
### 1. Clone and Setup
```bash
git clone https://github.com/yourusername/PersonalInternetCell.git
cd PersonalInternetCell
# Start with Docker (Recommended)
docker-compose up --build
# Or run locally
pip install -r api/requirements.txt
python api/app.py
```
### 2. Access Services
- **API**: http://localhost:3000
- **Health Check**: http://localhost:3000/health
- **Service Status**: http://localhost:3000/api/services/status
### 3. Use the Enhanced CLI
```bash
# Show cell status
python api/enhanced_cli.py --status

## 🏗️ Architecture
### **Service Manager Architecture**
All services inherit from `BaseServiceManager`, providing:
- **Unified Interface**: Consistent methods across all services
- **Health Monitoring**: Standardized health checks and metrics
- **Error Handling**: Centralized error handling and logging
- **Configuration**: Common configuration management patterns
### **Event-Driven Service Bus**
```python
# Services communicate via events
service_bus.register_service('network', network_manager)
service_bus.register_service('wireguard', wireguard_manager)
service_bus.publish_event(EventType.SERVICE_STARTED, 'network', data)
```
### **Service Dependencies**
```
wireguard → network
email → network, vault
calendar → network, vault
files → network, vault
routing → network, wireguard
vault → network
```
---
## 🔧 Service Managers
### **Core Network Services**
- **NetworkManager**: DNS, DHCP, NTP with dynamic zone management
- **WireGuardManager**: VPN configuration, peer management, key generation
- **PeerRegistry**: Peer registration, IP updates, trust management
### **Digital Services**
- **EmailManager**: SMTP/IMAP email with user management
- **CalendarManager**: CalDAV/CardDAV calendar and contacts
- **FileManager**: WebDAV file storage with user directories
### **Infrastructure Services**
- **RoutingManager**: NAT, firewall, advanced routing (exit/bridge/split)
- **VaultManager**: Certificate authority, trust management, encryption
- **ContainerManager**: Docker orchestration and container management
- **CellManager**: Overall cell configuration and service orchestration
