|
|
|
|
## Critical Services Priority List
|
|
|
|
Fix these services first due to security/stability concerns:
|
|
|
|
1. **N8N** (automation) - Weak password, no network isolation
|
|
2. **Bitwarden** (passwords) - Exposed admin token
|
|
3. **Gitea** (code repo) - No healthcheck, no dedicated network
|
|
4. **Blog/Helferlein** - EOL MySQL version
|
|
5. **Synapse + Bridges** - Network architecture needs improvement
|
|
6. **Services on compose_files_default** - Need network isolation
|
|

## Implementation Notes
|
|
|
|
### Before Starting Any Phase
|
|
|
|
1. **Full system backup**
|
|
- Backup all `/home/icke/` directories
|
|
- Export all databases
|
|
- Document current working state
|
|
|
|
2. **Create rollback plan**
|
|
- Keep old compose files as `.yml.backup`
|
|
- Document current container states
|
|
- Test rollback procedure
|
|
|
|
3. **Schedule maintenance window**
|
|
- Notify users of potential downtime
|
|
- Choose low-traffic time period
|
|
- Have monitoring ready
|
|
|
|
### Testing Strategy
|
|
|
|
1. Test changes on one service first
|
|
2. Monitor for 24 hours
|
|
3. Apply to similar services in batches
|
|
4. Keep previous configs for quick rollback
|
|
|
|
### Success Criteria
|
|
|
|
- All services start successfully
|
|
- No stale endpoint errors after `docker system prune`
|
|
- All services accessible via their original URLs/ports
|
|
- Logs flowing to Loki
|
|
- Healthchecks reporting healthy status
|
|
|
|
---
|
|
|
|
## Maintenance Schedule Recommendation
|
|
|
|
- **Phase 1:** Can be done immediately, low risk
|
|
- **Phase 2:** Schedule over 2-3 weekends
|
|
- **Phase 3:** One service per weekend, monitor for a week
|
|
- **Phase 4:** Full maintenance window, test environment first
|
|
|
|

|
|
|
|
## Additional Recommendations
|
|
|
|
### Future Improvements (Not in Roadmap)
|
|
|
|
- Consider Traefik/Nginx Proxy Manager for unified reverse proxy
|
|
- Implement automated backup solution (Duplicati, Restic, etc.)
|
|
- Add Prometheus monitoring for metrics collection
|
|
- Consider Watchtower for automated updates (carefully configured)
|
|
- Create Docker Swarm or K8s cluster for HA (if needed)
|
|
- Implement secrets management (Vault, Docker Secrets)
|
|
- Add CI/CD pipeline for compose file validation
|
|
|
|
### Documentation
|
|
|
|
- Document network architecture diagram
|
|
- Create service dependency map
|
|
- Maintain service inventory with versions
|
|
