# n8n-installer System Patterns
|
|
|
|
## Architectural Patterns
|
|
|
|
### Container Orchestration Pattern
|
|
- **Docker Compose**: Declarative service definition and management
|
|
- **Service Discovery**: Named containers for inter-service communication
|
|
- **Network Isolation**: Custom Docker networks for security boundaries
|
|
- **Volume Management**: Persistent data storage with named volumes
|
|
- **Environment Configuration**: Centralized secrets and settings via .env
|
|
|
|
### Reverse Proxy Pattern
|
|
- **Caddy as Gateway**: Single entry point for all services
|
|
- **Automatic SSL**: Let's Encrypt integration for certificate management
|
|
- **Subdomain Routing**: Service-specific subdomain mapping
|
|
- **Load Balancing**: Built-in support for service scaling
|
|
- **Static File Serving**: Efficient asset delivery
|
|
|
|
### Queue-Based Processing Pattern
|
|
- **Redis Queue**: Decoupled task execution in n8n
|
|
- **Worker Scaling**: Configurable parallel processing capacity
|
|
- **Job Distribution**: Load balancing across multiple workers
|
|
- **Persistence**: Task state management and recovery
|
|
- **Monitoring**: Queue depth and worker utilization tracking
|
|
|
|
### Configuration Management Patterns
|
|
|
|
### Environment-Based Configuration
|
|
```bash
|
|
# Central configuration in .env file
|
|
DOMAIN=yourdomain.com
|
|
N8N_WORKERS=2
|
|
POSTGRES_PASSWORD=secure_password
|
|
OPENAI_API_KEY=optional_key
|
|
```
|
|
|
|
### Service Selection Pattern
|
|
- **Interactive Wizard**: Runtime service selection during installation
|
|
- **Conditional Deployment**: Docker Compose service activation based on choices
|
|
- **Dependency Management**: Automatic inclusion of required supporting services
|
|
- **Resource Optimization**: Only deploy selected services to conserve resources
|
|
|
|
### Security Patterns
|
|
|
|
### Defense in Depth
|
|
1. **Network Level**: Firewall configuration and port management
|
|
2. **Application Level**: Service-specific authentication and authorization
|
|
3. **Transport Level**: Automatic HTTPS/TLS encryption
|
|
4. **Data Level**: Database password security and secret management
|
|
|
|
### Credential Management
|
|
- **Generated Secrets**: Automatic secure password creation
|
|
- **Environment Isolation**: Secrets stored in environment variables
|
|
- **Service Accounts**: Dedicated credentials for inter-service communication
|
|
- **Backup Security**: Encrypted credential storage in backup systems
|
|
|
|
## Installation and Deployment Patterns
|
|
|
|
### Progressive Installation Pattern
|
|
```bash
|
|
# Sequential script execution
|
|
01_system_preparation.sh # System updates and security
|
|
02_install_docker.sh # Container runtime
|
|
03_generate_secrets.sh # Security credentials
|
|
04_wizard.sh # Interactive configuration
|
|
05_run_services.sh # Service deployment
|
|
06_final_report.sh # Success confirmation
|
|
```
|
|
|
|
### Idempotent Operations
|
|
- **State Checking**: Verify current system state before modifications
|
|
- **Conditional Execution**: Skip already-completed installation steps
|
|
- **Error Recovery**: Resume installation from failure points
|
|
- **Rollback Capability**: Undo changes if deployment fails
|
|
|
|
### Update and Maintenance Patterns
|
|
|
|
### Rolling Update Pattern
|
|
1. **Backup Current State**: Preserve existing data and configurations
|
|
2. **Fetch Updates**: Pull latest code and Docker images
|
|
3. **Service Replacement**: Replace containers with minimal downtime
|
|
4. **Health Verification**: Confirm all services operational post-update
|
|
5. **Rollback on Failure**: Restore previous state if issues detected
|
|
|
|
### Cleanup Pattern
|
|
- **Resource Identification**: Scan for unused Docker resources
|
|
- **Safe Removal**: Delete only genuinely unused containers/images
|
|
- **Space Recovery**: Reclaim disk space without affecting running services
|
|
- **User Confirmation**: Require explicit approval for destructive operations
|
|
|
|
## Data Management Patterns
|
|
|
|
### Shared Storage Pattern
|
|
```
|
|
/data/shared/ # Host filesystem
|
|
↓
|
|
/data/shared/ # n8n container access path
|
|
```
|
|
- **File Exchange**: Common area for workflow file operations
|
|
- **Cross-Service Data**: Shared data access across multiple containers
|
|
- **Backup Inclusion**: Shared data included in backup processes
|
|
|
|
### Database Pattern
|
|
- **Shared Postgres**: Single database instance for multiple services
|
|
- **Schema Isolation**: Service-specific database schemas
|
|
- **Connection Pooling**: Efficient database connection management
|
|
- **Backup Strategy**: Regular automated database backups
|
|
|
|
### Vector Storage Pattern
|
|
- **Multiple Options**: Qdrant, Supabase, Weaviate for different use cases
|
|
- **Embedding Management**: Centralized vector storage and retrieval
|
|
- **Search Capabilities**: Semantic search across stored embeddings
|
|
- **Scaling Strategy**: Performance optimization for large datasets
|
|
|
|
## Monitoring and Observability Patterns

|
|
```
|

|
|
- **Log Aggregation**: Centralized log management
|
|
- **Error Tracking**: Exception monitoring and alerting
|
|

|
|
|
|
### Health Check Pattern
|
|
- **Service Health**: Individual container health verification
|
|
- **Dependency Health**: Inter-service connectivity testing
|
|
- **External Health**: Domain resolution and certificate validation
|
|
- **Automated Recovery**: Service restart on health check failure
|
|
|
|
## Integration Patterns
|
|
|
|
### API Gateway Pattern
|
|
- **Unified Interface**: Single API endpoint for external integrations
|
|
- **Authentication**: Centralized auth for API access

|
|
- **Secure Endpoints**: HTTPS webhook receivers
|
|
- **Payload Validation**: Input sanitization and verification

|
### File Processing Pattern
|
|
- **Watch Folders**: Monitor directories for new files
|
|
- **Processing Pipelines**: Multi-step file transformation workflows
|
|
- **Format Conversion**: Support for multiple input/output formats
|
|
- **Error Recovery**: Handle corrupted or invalid files gracefully
|
|
|
|
## Development and Testing Patterns
