# n8n Workflow Automation Template
|
||||
|
||||
## Overview
|
||||
n8n is a fair-code licensed tool that helps you automate tasks, workflows, and processes without the need for writing code.
|
||||
|
||||
## Quick Start
|
||||
```bash
|
||||
# Create docker-compose.yml with the content below
|
||||
docker-compose up -d

## Setup Guide
|
||||
1. **Generate Encryption Key**:
|
||||
```bash
|
||||
openssl rand -base64 32
|
||||
```
|
||||
|
||||
2. **Generate Secure Password**:
|
||||
```bash
|
||||
openssl rand -base64 16
|
||||
```
|
||||
|
||||
3. **Deploy**:
|
||||
```bash
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
4. **Access**: Open http://localhost:5678
|
||||
|
||||
5. **Initial Setup**:
|
||||
- Login with basic auth credentials
|
||||
- Create first workflow
|
||||
- Configure integrations
|
||||
|
||||
## Workflow Examples

||||
# Schedule: Every hour
|
||||
|
||||
# Example: Data Sync
|
||||
# Trigger: Schedule (daily)
|
||||
# Action: Google Sheets → Database
|
||||
# Error Handling: Retry on failure
|
||||
|
||||

|
||||
|
||||
## Reverse Proxy (Traefik)
|
||||
```yaml
|
||||
labels:
|
||||
- "traefik.enable=true"
|
||||
- "traefik.http.routers.n8n.rule=Host(`n8n.yourdomain.com`)"
|
||||
- "traefik.http.routers.n8n.tls=true"
|
||||
- "traefik.http.routers.n8n.tls.certresolver=letsencrypt"
|
||||
- "traefik.http.services.n8n.loadbalancer.server.port=5678"
|
||||
```
|
||||
|
||||
## Custom Nodes
|
||||
```yaml
|
||||
# Mount custom nodes directory
|
||||
volumes:
|
||||
- ./n8n-custom:/home/node/.n8n/custom
|
||||
|
||||
# Install custom nodes
|
||||
docker exec n8n npm install n8n-nodes-your-custom-node
|
||||
```
|
||||
|
||||
## Backup Strategy
|
||||
```bash
|
||||
# Backup n8n data
|
||||
docker run --rm -v n8n-data:/data -v $(pwd):/backup alpine tar czf /backup/n8n-data.tar.gz -C /data .
|
||||
|
||||
# Backup database
|
||||
docker exec n8n-postgres pg_dump -U n8n n8n > n8n-db-backup.sql
|
||||
|
||||
# Restore database
|
||||
docker exec -i n8n-postgres psql -U n8n n8n < n8n-db-backup.sql
|
||||
```
|
||||
|
||||
## Performance Optimization
|
||||
```yaml
|
||||
# For high-volume workflows
|
||||
environment:
|
||||
- N8N_EXECUTIONS_DATA_PRUNE=true
|
||||
- N8N_EXECUTIONS_DATA_MAX_AGE=168 # 7 days
|
||||
- N8N_QUEUE_BULL_REDIS_HOST=redis
|
||||
- N8N_QUEUE_BULL_REDIS_PORT=6379
|
||||
|
||||
# Resource limits
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
memory: 2G
|
||||
cpus: '1.5'
|
||||
```
|
||||
|
||||
## Security
|
||||
- Use strong passwords
|
||||
- Enable HTTPS
|
||||
- Regular updates
|
||||
- Network access control
|
||||
- Audit workflow executions
|
||||
|
||||
## Monitoring
|
||||
```bash
|
||||
# Check execution logs
|
||||
docker-compose logs -f n8n
|
||||
|
||||
# Monitor Redis queue
|
||||
docker exec n8n-redis redis-cli info
|
||||
|
||||
# Database status
|
||||
docker exec n8n-postgres psql -U n8n -c "SELECT count(*) FROM workflow_entity;"
|
||||
```
|
||||
|
||||
## Scaling
|
||||
```yaml
|
||||
# Worker nodes for execution
|
||||
n8n-worker:
|
||||
image: docker.n8n.io/n8nio/n8n:latest
|
||||
environment:
|
||||
- N8N_QUEUE_BULL_REDIS_HOST=redis
|
||||
depends_on:
|
||||
- redis
|
||||
networks:
|
||||
- n8n-network
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
- **Workflow failures**: Check execution logs
|
||||
- **Memory issues**: Increase memory limits
|
||||
- **Database errors**: Verify PostgreSQL connection
|
||||
- **SMTP problems**: Test email configuration
