+# Ollama
+
+LLM inference server with GPU acceleration. Runs on [[ringtail]] with declarative model management via a sidecar.
+
+## Quick Reference
+
+| Property | Value |
+|----------|-------|
+| **URL** | https://ollama.ops.eblu.me |
+| **Tailscale URL** | https://ollama.tail8d86e.ts.net |
+| **Namespace** | `ollama` |
+| **Cluster** | ringtail k3s |
+| **Image** | `ollama/ollama:0.17.5` |
+| **Upstream** | https://github.com/ollama/ollama |
+| **Manifests** | `argocd/manifests/ollama/` |
+| **API Port** | 11434 |
+
+## Architecture
+
+```
+models.txt (ConfigMap, declarative)

+model-sync sidecar ──ollama pull──► Ollama server (GPU)

+                /models (200 Gi hostPath PV)
+                /mnt/storage1/ollama on ringtail
+```
+
+## Models
+
+Declared in `argocd/manifests/ollama/models.txt`. The model-sync sidecar pulls missing models on startup and every 30 minutes.
+
+| Model | Parameters |
+|-------|------------|
+| `qwen2.5:14b` | 14B |
+| `deepseek-r1:14b` | 14B |
+| `phi4:14b` | 14B |
+| `gemma3:12b` | 12B |
+
+To add or remove models, edit `models.txt` and sync via ArgoCD.
+
+## GPU
+
+Shares [[ringtail]]'s RTX 4080 with [[frigate]] via NVIDIA device plugin time-slicing (2 virtual slots). Constrained to one loaded model and one parallel request to avoid VRAM contention.
+
+| Setting | Value |
+|---------|-------|
+| `OLLAMA_MAX_LOADED_MODELS` | 1 |
+| `OLLAMA_NUM_PARALLEL` | 1 |
+| GPU limit | `nvidia.com/gpu: "1"` (time-sliced) |
+
+## Storage
+
+| Mount | Backend | Size |
+|-------|---------|------|
+| `/models` | hostPath PV (`/mnt/storage1/ollama`) | 200 Gi |
+
+PV reclaim policy is `Retain` — models survive PV deletion.
+
+## Networking
+
+| Endpoint | Reachable from |
+|----------|----------------|
+| `https://ollama.ops.eblu.me` | Public internet (Fly.io → Caddy) |
+| `https://ollama.tail8d86e.ts.net` | Tailnet clients |
+| `http://ollama.ollama.svc.cluster.local:11434` | In-cluster (ringtail) |
+
+Tailscale ingress uses ProxyGroup `ingress` — no explicit `host:` field (see [[tailscale-operator]]).
