Previously published "9090:9090" → Docker bound to 0.0.0.0 (all host interfaces,
including the public Hetzner IP), leaving tailscale-internal enforced only by the
VPS firewall. Now bind explicitly to the VPS Tailscale interface for
defense-in-depth: the port does not exist on the public IP at all.
- ports -> "${TAILSCALE_BIND_IP}:9090:9090"
- env.example: add TAILSCALE_BIND_IP (VPS Tailscale IP, verify via `tailscale ip -4`)
- README: deploy section — .env is mandatory; a missing .env makes Compose
silently bind 0.0.0.0 (warns, does not fail), so use --env-file and verify host_ip
Smoke: config with --env-file and with co-located .env both resolve
host_ip=100.95.58.48; with .env absent Compose warns and falls back to 0.0.0.0
(documented). .env is gitignored (global *.env rule).

Homelab Codex
GitOps-lite orchestration for a distributed homelab environment.
Architecture
The homelab consists of several nodes connected via a Tailscale internal mesh.
| Host | Role | Description |
|---|---|---|
| SATURN | Primary Node | Development, orchestration, and git source of truth (commit node). |
| SOLARIA | Compute Node | GPU, inference, and heavy compute workloads. |
| PIHA | Infra Node | Core infrastructure services, automation, and monitoring. |
| VPS | Edge Node | Public ingress, reverse proxy, and edge services. |
Agent System
The homelab uses a multi-agent orchestration model with human-in-the-loop for destructive actions:
| Agent | Node | Role |
|---|---|---|
| stability-agent | all nodes | Per-node watchdog — monitors Docker, disk, Tailscale, MQTT; emits events |
| node-agent | all nodes | Publishes container health events to Redis pub/sub |
| observer | VPS | Synthesizes world state from events into /opt/homelab/world/*.json |
| supervisor | VPS | Detects drift between desired and actual state; writes pending actions |
| planner-agent | SOLARIA | LLM-powered diagnosis — listens to Redis, proposes remediation actions |
| executor | VPS | Executes actions only after operator approval |
| operator-ui + telegram-bot | VPS / PIHA | Operator reviews and approves/rejects pending actions |
Action approval flow: pending/ → operator approves → approved/ → executor runs.
