• Integrated AI capabilities into user environment and toolchain
🎯 KEY CAPABILITIES IMPLEMENTED:
✅ Intelligent code analysis and generation across multiple languages
✅ Infrastructure-aware AI that understands NixOS home lab architecture
✅ Context-aware assistance for fullstack web development workflows
✅ Privacy-preserving local AI processing with enterprise-grade security
✅ Automated project management and task orchestration
✅ Real-time monitoring and health checks for AI services
✅ Scalable architecture supporting future AI model additions
🔒 SECURITY & PRIVACY FEATURES:
• Complete local processing - no external API calls
• Security hardening with restricted user permissions
• Resource limits and isolation for AI services
• Comprehensive logging and monitoring for security audit trails
📈 IMPLEMENTATION ROADMAP:
• Phase 1: Foundation & Core Services (Weeks 1-3) ✅ COMPLETED
• Phase 2: RAG Integration (Weeks 4-6) - Ready for implementation
• Phase 3: MCP Integration (Weeks 7-9) - Architecture defined
• Phase 4: Advanced Features (Weeks 10-12) - Roadmap established
This integration transforms the home lab into an intelligent development environment where AI understands infrastructure, manages complex projects, and provides expert assistance while maintaining complete privacy through local processing.
IMPACT: Creates a self-contained, intelligent development ecosystem that rivals cloud-based AI services while maintaining complete data sovereignty and privacy.
- Create shared media-group.nix module with fixed GID (993)
- Add both geir and sma users to media group for shared NFS access
- Update NFS server configuration to use root:media ownership with 0775 permissions
- Convert all media services to use media group instead of users group:
- Jellyfin, Calibre-web, Audiobookshelf, Transmission
- Enable group write access to all NFS shares (/mnt/storage/*)
- Maintain security with root ownership while allowing group collaboration
This resolves NFS permission issues by providing consistent group-based access
control across all media services and storage directories.
- Port 1337 appears to be blocked by VPS provider
- Port 2222 is more commonly allowed for SSH services
- Update both reverse-proxy and Forgejo configurations
- This should resolve the SSH timeout issues
- Update Forgejo service configuration on grey-area
- Refine reverse-proxy network configuration
- Add README_new.md with enhanced documentation structure
- Update instruction.md with latest workflow guidelines
- Enhance plan.md with additional deployment considerations
- Complete PR template restructuring for professional tone
These changes improve service reliability and documentation clarity
while maintaining infrastructure consistency across all machines.
- Remove duplicate sma user definition from incus.nix module
- The sma user is properly defined in modules/users/sma.nix with incus-admin group
- This resolves the isNormalUser/isSystemUser assertion failure blocking congenital-optimist rebuild
- Clean up grey-area configuration and modularize services
- Update SSH keys with correct IP addresses for grey-area and reverse-proxy
- Add nginx stream configuration on reverse-proxy to forward port 2222 to apps:22
- Update firewall rules to allow port 2222 for Git SSH access
- Configure Forgejo to use SSH_PORT = 2222 for Git operations
- Add comprehensive SSH forwarding research documentation
- Enable Git operations via git@git.geokkjer.eu:2222
Phase 1 implementation using nginx stream module complete.
Ready for testing and potential Phase 2 migration to HAProxy.
- Removed system/ directory, merged applications into users/geir.nix
- Simplified fonts.nix to bare minimum (users can add more)
- Moved transmission.nix to sleeper-service/services/ (machine-specific)
- Organized grey-area services into services/ directory
- Updated import paths and tested all configurations
- Added research documentation for deploy-rs and GNU Stow
