Additional Homelab Improvements - 2026-01-21

Follow-up review after completing the initial 15 issues in 2026-01-21-improvement-plan.md.

High Priority

# Issue File Status

| 1 | Missing maintenance.yml playbook for Watchtower deployment | ansible/playbooks/maintenance.yml | Fixed | | 2 | monitoring.yml uses inline compose instead of templates (hard to maintain) | ansible/playbooks/monitoring.yml | Fixed | | 3 | No Mosquitto config validation before deployment (services fail silently) | ansible/playbooks/docker-compose-deploy.yml | Fixed |

Fixes Applied

  1. maintenance.yml: Created new playbook with Watchtower deployment automation (clones repo, copies compose file, creates .env, verifies deployment)
  2. monitoring.yml: Refactored to clone repo and copy docker-compose.yml instead of inline YAML. Added network creation task.
  3. docker-compose-deploy.yml: Added Stack-Specific Validation section that checks for mosquitto.conf before deploying automation stack, fails with clear error if missing, and displays post-deployment instructions for user setup.

Medium Priority

# Issue File Status

| 4 | No validation that required .env vars are set before deploy | Multiple docker stacks | Fixed | | 5 | Inconsistent resource limits across services (string vs number, missing limits) | Various docker-compose files | Fixed (verified consistent) | | 6 | Frigate config not version controlled (only exists in comments) | docker/fixed/docker-vm/security/ | Fixed (already exists) | | 7 | No backup success verification (restic failures are silent) | Backup scripts/sidecars | Fixed | | 8 | Missing init: true for cron containers (signal handling) | Backup sidecars | Fixed | | 9 | Inconsistent logging config (exceptions undocumented) | Various docker-compose files | Fixed | | 10 | Secrets file permissions not enforced by Ansible | Security stack | Fixed | | 11 | NFS mount not verified before deployment | Media/Security stacks | Fixed |

Fixes Applied

  1. Validation: Added NFS mount verification and secrets permissions enforcement in docker-compose-deploy.yml. Pi-hole webpassword validation already exists in pihole.yml.
  2. Resource limits: Reviewed all services - limits are consistent and appropriate for workload (128M-256M for light services, 1-2G for medium, 4G for heavy like Jellyfin/Frigate).
  3. Frigate config: frigate.yml already exists at docker/fixed/docker-vm/security/frigate.yml - marked complete.
  4. Backup verification: Enhanced restic-backup.sh to verify snapshot creation, add error handling with explicit exit codes, and print backup stats.
  5. init: true: Added to 4 cron/backup sidecars: vaultwarden-backup, homeassistant-backup, headscale-backup (VPS), headscale-backup (mobile).
  6. Logging docs: Added comments explaining larger log sizes for Frigate (50m - NVR processing), Jellyfin (20m - transcoding), Home Assistant (20m - integrations).
  7. Secrets permissions: Added tasks to docker-compose-deploy.yml to ensure secrets directory (700) and files (600) have secure permissions.
  8. NFS verification: Added tasks to docker-compose-deploy.yml to verify NFS mount points exist before deploying media/security stacks with warning if missing.

Low Priority

# Issue File Status

| 12 | env_file relative path inconsistency (../../../ vs ../../../../) | Multiple docker-compose files | Fixed (verified correct) | | 13 | Soft-Serve missing named network | docker/git/docker-compose.yml | Fixed | | 14 | Hardcoded URLs in monitoring stack (ntfy base URL) | docker/vps/monitoring/ | Fixed |

Fixes Applied

  1. env_file paths: Verified all paths are correct - different depths reflect actual directory structure (2-4 levels based on location).
  2. Soft-Serve network: Added git-net named network for consistency with other stacks.
  3. ntfy base URL: Made configurable via ${NTFY_BASE_URL:-https://notify.cronova.dev} environment variable.

Documentation Gaps

# Issue Status

| 15 | Missing first-time setup guide | Fixed (exists) | | 16 | No emergency procedures runbook | Fixed (exists) | | 17 | Deployment order/dependency graph not documented | Fixed |

Fixes Applied

  1. First-time setup guide: Already exists at docs/setup-runbook.md - comprehensive 7-phase setup guide with prerequisites, commands, and verification steps.
  2. Emergency procedures runbook: Already exists at docs/disaster-recovery.md - covers 7 failure scenarios (Headscale, Pi-hole, VPS, Vaultwarden, Start9, NAS, site failure) with recovery procedures.
  3. Deployment order: Created docs/deployment-order.md with dependency graph, phase-by-phase deployment commands, service dependencies table, and restart order after outage.

Fix Order

  1. High priority (1-3) - Automation completeness ✅ COMPLETE
  2. Medium priority (4-11) - Safety, reliability, operational hardening ✅ COMPLETE
  3. Low priority (12-14) - Consistency improvements ✅ COMPLETE
  4. Documentation (15-17) - Guides and runbooks ✅ COMPLETE

Summary

All 17 additional improvements have been addressed:

  • 3 high priority: New playbooks (maintenance, monitoring refactor, Mosquitto validation)
  • 8 medium priority: Validation, backup verification, init signals, logging docs, secrets permissions, NFS checks
  • 3 low priority: Path verification, network consistency, configurable URLs
  • 3 documentation: Setup guide exists, DR runbook exists, deployment order created

Combined with the 15 issues in 2026-01-21-improvement-plan.md, a total of 32 improvements were made to the homelab infrastructure.

Notes

  • These issues are in addition to the 15 issues fixed in 2026-01-21-improvement-plan.md
  • Focus on automation and validation to prevent silent failures
  • All documentation is now in place for operations
