# Architecture Overview
|
|
|
|
Full homelab stack as of 2026-05-09. All 6 expansion phases are complete and deployed.
|
|
|
|
## Servers
|
|
|
|
| Server | OS | IP | Role |
|
|
|--------|----|----|------|
|
|
| **PlausibleDeniability (PD)** | TrueNAS Scale 25.10.2.1 | 10.5.1.6 | Primary Docker host — all compose stacks |
|
|
| **Serenity** | Unraid 7.2.4 | 10.5.1.5 | NAS, ARR stack, CPU reranker |
|
|
| **N.O.M.A.D.** | Ubuntu 25.10 | 10.5.1.16 | Light Ollama models, game servers |
|
|
| **Rocinante** | (bare metal) | 10.5.1.112 | Heavy Ollama models (RTX 4090) |
|
|
|
|
## Network
|
|
|
|
- **LAN subnet:** 10.5.1.0/24
|
|
- **Tailscale:** Serenity reachable at 100.94.87.79
|
|
- **NFS:** Serenity exports `/mnt/user/data` and `/mnt/user/immich` → mounted on PD at `/mnt/unraid/` via post-init script
|
|
- **Docker networking:** Cross-stack communication via named external networks (`ai-services`, `ix-databases_shared-databases`)
|
|
|
|
## Stack Overview
|
|
|
|
### Infrastructure Layer
|
|
- **Homepage** (3300) — dashboard / service index
|
|
- **Uptime Kuma** (3001) — monitoring and alerting
|
|
- **Gotify** (8443) — push notifications
|
|
- **Gitea** (3002) — self-hosted git
|
|
- **Dockhand** (3230) — Docker management UI
|
|
|
|
### AI Layer
|
|
- **LiteLLM** (4000) — unified LLM proxy; routes to Ollama on N.O.M.A.D. (light) and Rocinante (heavy)
|
|
- **OpenWebUI** (8282) — chat UI with RAG, STT, and web search
|
|
- **Qdrant** (6333/6334) — vector database for RAG
|
|
- **Whisper** (8786) — CUDA speech-to-text on PD's RTX 2080 Ti
|
|
- **SearXNG** (8888) — private web search backend
|
|
- **Reranker** (Serenity:9787) — TEI bge-reranker-v2-m3, CPU-only
|
|
|
|
### Media Layer
|
|
- **Plex** (32400), **Tautulli** (8181), **Audiobookshelf** (13358), **Calibre** (8183), **Seerr** (5055) — all on PD
|
|
- ARR stack on Serenity (Sonarr, Radarr, Prowlarr, qBittorrent)
|
|
|
|
### Productivity Layer
|
|
- **Immich** (2283) — photo management; library on Serenity NFS
|
|
- **Paperless-NGX** (8083) — document management
|
|
- **Karakeep** (3100) — bookmarks / read-later
|
|
- **n8n** (5678) — workflow automation
|
|
- **KitchenOwl** (8086), **DoneTick** (2021) — household and task management
|
|
|
|
### Smart Home Layer
|
|
- **Home Assistant** (8123) — home automation hub
|
|
- **Kima Hub** (3333) — custom IoT gateway
|
|
|
|
### Monitoring Layer
|
|
- **Grafana** (3000) + **Prometheus** (9090) — metrics and dashboards
|
|
- **MeshMonitor** (8081) — network mesh visibility
|
|
|
|
## Key Architectural Decisions
|
|
|
|
1. **LiteLLM as unified proxy** — all AI clients target LiteLLM; model routing is transparent to clients
|
|
2. **Reranker on Serenity (CPU)** — frees RTX 2080 Ti on PD exclusively for Whisper CUDA; CPU latency acceptable for RAG reranking
|
|
3. **External Docker networks** — `ai-services` bridges all AI containers across compose files; `ix-databases_shared-databases` provides shared DB access
|
|
4. **NFS for Immich** — photo library lives on Serenity's large array; PD mounts on demand (not at boot)
|
|
5. **TrueNAS manages Docker** — never use `systemctl restart docker` on PD; use `docker compose` or `docker restart` for individual containers
|
|
6. **Credential hygiene** — Gitea remote uses HTTPS + credential store; GitHub remote uses SSH key (`/root/.ssh/id_gitea`)
