# REVIEW MY DEPLOYMENT — I WANT YOUR FEEDBACK AND ADVICE Below is my full deployment environment, inventoried live off the machine on 2026-11-13. I run all of this myself. I'm not asking you to compare yourself to other models — I'm asking you to actually understand MY system and give me your best feedback and advice on it, the way a sharp infrastructure engineer who just got read in on this box would. Be specific. Everything you say must tie to a named component, version, port, or number in this inventory. Generic advice that could apply to any server is worthless to me. Distinguish what's RUNNING from what's STOPPED. Distinguish local capacity from cloud-backed capacity. If you get something about my system wrong, that tells me a lot; if you need information the inventory doesn't have, say exactly what you'd inspect and why. ## MY STACK (the languages and tools this environment is actually built from) - Python 3.14 (custom FastAPI/uvicorn voice service, a Python queue service in front of the image API, assorted glue) - TypeScript end to end for my main app: Express API server + React/Vite web client, and a native iOS client in Swift 6 / SwiftUI / SwiftData that shares the same backend contracts - PostgreSQL everywhere (host v18 + at least four containerized instances), Docker Compose stacks, a Coolify PaaS on top of Docker - systemd (system + user units, linger), Cloudflare (Tunnel, WAF rules, DNS across 7 zones), Tailscale (mesh + SSH), UFW - Ollama serving GGUF models over its OpenAI-compatible API, Stable Diffusion Forge over the A1111 API ## THE ENVIRONMENT ### Hardware / OS — one machine runs everything below Lenovo Legion Slim 5 laptop: AMD Ryzen 5 7640HS (6c/12t), 14 GiB RAM, 468 GB NVMe (66% used), NVIDIA RTX 4060 Laptop GPU with 8 GB VRAM (the only accelerator for all local AI), Ubuntu 26.04.1 LTS. On AC power; the battery reports 0%. ### Local inference — Ollama (systemd, API on *:11434) Local GGUF: Gemma4-12B Q4_K_M (7.6 GB), gemma-4-12B-heretic Q4_K_M (7.4 GB), Hermes-3-Llama-3.1-8B Q4_K_M (4.9 GB), a Dolphin fine-tune (4.9 GB), gemma3:1b (1 GB). Embeddings: bge-m3, mxbai-embed-large, nomic-embed-text. Also exposed through the same Ollama API but running on the provider's cloud (NOT local capacity): DeepSeek V4 Pro, DeepSeek V4.1 Flash, DeepSeek V4 Flash, GLM 5.1 / 5.3 Flash, Kimi K2.7 Code. Front ends: Open WebUI (container), LibreChat, a custom web harness that launches a cloud model. ### Image generation — Stable Diffusion Forge (systemd, 0.0.0.0:7860) 4 SDXL checkpoints (Juggernaut XL + 3 photorealism models). A custom Python service ("sdqueue") serializes requests in front of the Forge API. ### Voice — custom FastAPI service (systemd user unit, 0.0.0.0:8020) faster-whisper large-v3 speech-to-text (CPU int8 by design), Piper TTS (1 preset voice), Chatterbox voice cloning (lazy-loads onto the GPU, ~4.8 GB VRAM once resident). Clone profiles on disk: 0. ### Agent / MCP layer A "Hermes Agent Gateway" (messaging-platform integration) on 0.0.0.0:8642. ToolHive runs MCP servers on *:8000 and *:8585, plus an MCP-over-SSH proxy pair. Self-hosted Forgejo git server (container). code-server + VS Code tunnel for remote IDE access. ### Containers / platforms — Docker: 33 running, 43 images, 53 volumes - Coolify self-hosted PaaS (own Postgres, Redis, realtime, Traefik proxy) deploying apps on this box - TWO Supabase stacks (Postgres, PostgREST, GoTrue auth, storage, Studio, imgproxy) - A "Happier" stack: server (0.0.0.0:3005, 9090), webapp (8081), Postgres published on 0.0.0.0:5434, Redis published on 0.0.0.0:6379 - A "Suvra" platform: API, an MCP server, worker, console, documentation, marketing site - Qdrant vector database; Uptime Kuma monitoring; the cloudflared tunnel as a container - Host PostgreSQL 18 as a systemd service, in addition to all containerized databases ### Observability — partially dark Datadog agent suite on the host + OTel collectors listening on *:4317/4318. SigNoz: alertmanager and zookeeper RUNNING, but its query service and ClickHouse are STOPPED. Langfuse (LLM tracing): only MinIO and Redis up; its worker is STOPPED. ### Exposure — how this box is reached 1. Public internet via Cloudflare Tunnel (no router port-forwards): three AI endpoints (Ollama, SD, voice subdomains) behind a WAF rule requiring a verified mTLS client cert OR a static X-API-Key header. ONE shared key gates all three; the same key also lives in my Replit app's secrets and in the iOS app's config, because a Replit-hosted web app and the iOS app consume these endpoints server-side. 2. A second hostname on another domain exposes the Ollama API through the tunnel; the Happier daemon has its own subdomain. 3. Tailscale mesh: the box offers itself as an exit node; SSH is Tailscale SSH with interactive check approval. Peers include two MacBooks, an iPhone, a tablet, two TVs, and an AI assistant's VM that administers this box over SSH. 4. Home LAN (UFW active, 40+ rules incl. docker-bridge allowances): SSH 22, Samba 139/445, and bound to all interfaces — the unauthenticated Ollama API (11434), Forge (7860), voice (8020), Hermes gateway (8642), ToolHive (8000/8585), plus Docker-published Postgres (5434) and Redis (6379). Docker's NAT bypasses UFW for published ports. 5. Dead access paths still present: Chrome Remote Desktop (failed systemd unit), a failed LAN proxy unit, a stopped Portainer container. ### A live problem you should know about My main app (TypeScript, Replit-hosted) intermittently fails chat generation against the Ollama endpoint with an opaque "private service is temporarily unavailable" error. It got 1 of 5 attempts through in the latest test. The upstream HTTP status and error body have never been captured anywhere, so after several days the root cause is still undiagnosed. The model it currently runs is the hardcoded gemma3:1b, not the Hermes-3 8B that was intended. ## WHAT I WANT BACK — answer in exactly these sections **1. Your read of this system.** In your own words: what is this box, what is it for, and what kind of operation am I running? (If your summary invents things that aren't in the inventory, I'll notice.) **2. What's sound.** The genuinely good decisions in this setup, tied to specific components — not compliments, judgments. **3. Risks, ranked.** My real risks ordered by blast radius. For each: the component, the failure or attack, and what it takes down with it. **4. Diagnose my live problem.** The failing chat generation above. Walk me through YOUR diagnosis in THIS environment, step by step, in order: the exact services, logs, files, and endpoints you'd check first (name them — journald units, container logs, tunnel, WAF, the API server, the client), what each step rules in or out, and what you'd instrument so this class of failure can never stay invisible again. **5. One weekend to harden this box.** Your prioritized plan, in order, concrete enough to execute: name the actual tools, files, services, and settings you'd touch. Respect that this is one laptop run by one person — no enterprise theater. **6. What am I missing entirely?** Scopes, gates, practices, or failure modes that don't appear anywhere in this inventory and should. **7. Your confidence.** Where are you least certain about this system from the inventory alone, and what would you want to inspect before standing behind your advice?
