Detailed documentation for Matrix components should be maintained separately. ================================================================================ IMPORTANT NOTES ================================================================================ 1. node-staging Database - Intentionally does NOT replicate from primary server - Used exclusively for financial bot testing - Provides isolated testing environment - Critical for Node-RED financial automation 2. Firefly III Version - Pinned to version 6.2.21 - Known working version with automated transactions - Do NOT update without testing automation compatibility 3. Traefik Configuration - Managed via traefik-mod web interface (tm.3ddbrewery.com) - Direct YAML editing discouraged - All changes version-controlled via Git - Database-backed with automatic YAML generation 4. MariaDB Management - User prefers phpMyAdmin for database management - Access via primary server phpMyAdmin - Connect to 192.168.12.3:3306 - No root password required in .env files 5. Authelia - Docker-compose.yml exists but containers not running - Alternative to Authentik (not currently in use) - Could be started if needed ================================================================================ ISSUES AND GAPS ================================================================================ None identified. All documentation complete. All containers in /volume1/docker have been documented: ✓ Complete service inventory with technical details ✓ All database instances documented with access methods ✓ Complete network architecture with 18 networks mapped ✓ Custom applications (traefik-mod, Node-RED) fully documented ✓ README overview with quick reference and troubleshooting Matrix/Synapse containers listed as requested (no deep documentation). No missing information or gaps in documentation. ================================================================================ DOCUMENTATION READY FOR TRANSFER ================================================================================ All files in /home/maddox/hetzner-docs/ are ready to be transferred to the main server's Silverbullet documentation system.
