🔧 Service Manager Architecture

BaseServiceManager Pattern

All services inherit from BaseServiceManager, providing:

class BaseServiceManager(ABC):
    def __init__(self, service_name: str, data_dir: str, config_dir: str)
    
    @abstractmethod
    def get_status(self) -> Dict[str, Any]
    
    @abstractmethod
    def test_connectivity(self) -> Dict[str, Any]
    
    # Common methods
    def get_logs(self, lines: int = 50) -> List[str]
    def restart_service(self) -> bool
    def get_config(self) -> Dict[str, Any]
    def update_config(self, config: Dict[str, Any]) -> bool
    def health_check(self) -> Dict[str, Any]
    def handle_error(self, error: Exception, context: str) -> Dict[str, Any]

Service Bus Integration

# Event-driven service communication
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
service_dependencies = {
    'wireguard': ['network'],
    'email': ['network', 'vault'],
    'calendar': ['network', 'vault'],
    'files': ['network', 'vault'],
    'routing': ['network', 'wireguard'],
    'vault': ['network']
}
