# HVAC Know It All - Deployment Strategy

## Summary

After thorough testing and implementation, the content aggregation system has been successfully built with 6 scrapers. However, deployment strategy has been revised due to technical constraints with TikTok scraping requirements.

## Source Status

### ✅ Working Sources (5/6)
- **WordPress Blog**: REST API - ✅ Working
- **MailChimp RSS**: RSS Feed - ✅ Working  
- **Podcast RSS**: Libsyn Feed - ✅ Working
- **YouTube**: yt-dlp - ✅ Working
- **Instagram**: instaloader with session persistence - ✅ Working

### ⚠️ TikTok Constraints
- **TikTok**: Requires headed browser with DISPLAY=:0 for bot detection avoidance
- **Cannot be containerized** due to GUI browser requirement
- **Not suitable for Kubernetes deployment**

## Deployment Decision

### Original Plan: Kubernetes Container
- ❌ **Not viable** due to TikTok headed browser requirement
- ❌ Running GUI applications in containers adds significant complexity
- ❌ Display forwarding in Kubernetes is not practical for production

### Revised Plan: Direct System Service

**Deploy as systemd service on control plane node:**

1. **Installation Location**: `/opt/hvac-kia-content/`
2. **Service Management**: systemd units for scheduling
3. **Environment**: Direct execution on control plane with DISPLAY access
4. **Scheduling**: cron-like scheduling via systemd timers

## Benefits of Direct Deployment

### ✅ Advantages
- **Simple deployment** - no container complexity
- **Full system access** - DISPLAY, browsers, sessions
- **Reliable TikTok scraping** - headed browser support
- **Easy maintenance** - direct file access and logging
- **Resource efficiency** - no container overhead

### ⚠️ Considerations
- **Host dependency** - requires control plane node
- **Manual updates** - no container image versioning
- **Environment coupling** - tied to specific system

## Implementation Plan

### Phase 1: Service Setup
1. Install Python environment at `/opt/hvac-kia-content/`
2. Configure environment variables and credentials
3. Set up logging directory with rotation
4. Create systemd service unit

### Phase 2: Scheduling
1. Create systemd timer units for 8AM and 12PM ADT
2. Configure NAS sync via rsync
3. Set up monitoring and alerting

### Phase 3: Monitoring
1. Log rotation and archival
2. Health checks and status reporting
3. Error notification system

## File Structure

```
/opt/hvac-kia-content/
├── src/                    # Source code
├── logs/                   # Application logs
├── data/                   # Scraped content and state
├── .env                    # Environment configuration

    ├── hvac-scraper.service
    ├── hvac-scraper-morning.timer
    └── hvac-scraper-afternoon.timer
```

## NAS Integration

**Sync to**: `/mnt/nas/hvacknowitall/`
- Markdown files with timestamped archives
- Organized by source and date
- Incremental sync to minimize bandwidth

## Conclusion

While the original containerized approach is not viable due to TikTok's GUI requirements, the direct deployment approach provides a robust and maintainable solution for the HVAC Know It All content aggregation system.

The system successfully aggregates content from 5 major sources with the option to include TikTok when needed, providing comprehensive coverage of the HVAC Know It All brand across digital platforms.
