# Quickstart

Homelab host: **`192.168.8.123`** (SER5, Ubuntu 24.04)  
Stack: **`/opt/stack`** · Media: **`/storage`** · User: **`tim`**

---

## Ansible

From a machine with this repo and SSH key `~/.ssh/id_ed25519`:

```bash
cd ansible
ansible-galaxy collection install -r requirements.yml

ansible-playbook site.yml -K          # -K only if sudo still asks once; playbook installs NOPASSWD for tim
```

What it does: OS updates, tools (incl. Microsoft `edit`), Docker, AMD/Vulkan, UFW (LAN only), `/opt/stack` + `/storage`, `.env`, `arr-stack.service`, and **tim** as local admin (passwordless sudo, docker/video/render/…, owns stack + storage, permissive GPU nodes).

**Before first full stack start** (on ser5):

```bash
ssh tim@192.168.8.123
# new login so docker/video/render groups apply
cd /opt/stack
# wireguard/wg0.conf must exist (no IPv6; Endpoint = IP not hostname)
./scripts/download-bonsai-model.sh    # ~7.2 GB GGUF
docker compose build bonsai
docker compose up -d
# or: sudo systemctl enable --now arr-stack
docker compose ps
```

**Compose GPU notes**
- Keep `devices`/`group_add` only in `docker-compose.override.yml` (not also in the main file).
- Use **numeric GIDs** for `group_add`, not names (`video`/`render` fail inside the image). Or omit `group_add` if `/dev/dri` is mode `0666`.


Re-run playbook anytime: `ansible-playbook site.yml -K`

## Remotes

LAN URLs (UFW allows **`192.168.8.0/24`**). Replace host if needed.

| Service | URL |
|---------|-----|
| Jellyfin | http://192.168.8.123:8096 |
| qBittorrent | http://192.168.8.123:8080 |
| Prowlarr | http://192.168.8.123:9696 |
| Sonarr | http://192.168.8.123:8989 |
| Radarr | http://192.168.8.123:7878 |
| Bazarr | http://192.168.8.123:6767 |
| Lidarr | http://192.168.8.123:8686 |
| Open WebUI | http://192.168.8.123:3000 |
| Bonsai API | http://192.168.8.123:8081/v1 |
| OpenHands | http://192.168.8.123:3001 |
| **Forgejo** | http://192.168.8.123:3002 |
| Forgejo Git SSH | `ssh://git@192.168.8.123:2222/user/repo.git` |

OpenHands only runs with: `docker compose --profile coding up -d` (or `stack_compose_profiles: [coding]` in Ansible).  
Images are from **GHCR** (`ghcr.io/all-hands-ai/...`); the old `docker.all-hands.dev` host often does not resolve.

### Manual config (once)

**qBittorrent** — temp password in `docker logs qbittorrent`; user `admin`.  
Advanced → Network interface: `tun0`.

Default save path + categories (WebUI):

1. **Tools → Options → Downloads**  
   - Default Save Path: `/data/torrents`  
   - Keep “Keep incomplete torrents in” off (or a subfolder under `/data/torrents` if you prefer).
2. **Categories** (same Options → Downloads page, or right‑click empty area in the left “Categories” panel → **Add category**):

   | Category name | Save path |
   |---------------|-----------|
   | `movies` | `/data/torrents/movies` |
   | `tv` | `/data/torrents/tv` |
   | `music` | `/data/torrents/music` |

   For each: **Add category** → name exactly `movies` / `tv` / `music` (lowercase, matches Sonarr/Radarr/Lidarr) → set **Save path** to the path above → OK.

3. Sonarr/Radarr/Lidarr download-client “Category” fields must match those names so torrents land in the right folder for hardlinks.

**Sonarr / Radarr / Lidarr** — Download client qBittorrent: host **`gluetun`**, port **`8080`**, categories `tv` / `movies` / `music`.  
Root folders: `/data/media/tv`, `/data/media/movies`, `/data/media/music` (hardlinks on).

**Prowlarr** — Add indexers. Apps: Sonarr `http://sonarr:8989`, Radarr `http://radarr:7878`, Lidarr `http://lidarr:8686` + each API key (*Settings → General*).

**Bazarr** — Sonarr/Radarr URLs + API keys; paths `/data/media/tv`, `/data/media/movies`.

**Jellyfin** — Libraries: Movies `/data/media/movies`, Shows `/data/media/tv`, Music `/data/media/music`.

**Open WebUI** — Create admin on first visit. Model connection is pre-set to Bonsai (`http://bonsai:8080/v1`). Enable web search in chat if desired. RAG: Workspace → Knowledge (uploads) or files under `/workspace`.

**Bonsai** — No UI login. Smoke test: `curl -s http://192.168.8.123:8081/v1/models`. Needs GGUF in `models/bonsai/` and `docker compose build bonsai` once.

**OpenHands** — On the server (`/opt/stack`): `docker compose --profile coding up -d openhands`.  
UI: http://192.168.8.123:3001  

**LLM (required once)**  
Settings → Advanced: base URL `http://bonsai:8080/v1`, API key `sk-local-bonsai`, model `openai/<id from /v1/models>`.

**Connect to Forgejo (pick A and/or B)**

**A — Provider (browse / open repos in OpenHands)**  
1. Forgejo → avatar → **Settings → Applications** → generate a token (scopes: `read:repository`, `write:repository`, `read:user` — or full access on a trusted LAN).  
2. OpenHands → **Settings → Git / Integrations** (or **Secrets** / provider list):  
   - Provider: **Forgejo** or **Gitea** (same API)  
   - Base URL: `http://forgejo:3000` (Docker DNS on `arr-net`; use this from OpenHands)  
     From a browser on your PC you use `http://192.168.8.123:3002` — that is *not* what the OpenHands container should use.  
   - Token: paste the Forgejo token  
3. Start a conversation → choose repository → `tim/stack`.

**B — Workspace mount (most reliable for editing + git push)**  
Compose already mounts `${AI_WORKSPACE_DIR}` (default `/opt/stack/workspace`) into the agent sandbox as `/workspace`.  
On the **server**:

```bash
# HTTPS with token (one-time; token in URL — prefer SSH below)
# git clone http://tim:TOKEN@192.168.8.123:3002/tim/stack.git /opt/stack/workspace/stack

# SSH (key already on Forgejo for user tim)
git clone ssh://git@192.168.8.123:2222/tim/stack.git /opt/stack/workspace/stack
```

Then in OpenHands: work in `/workspace/stack` (or set the conversation workspace to that path).  
Agent can `git commit` / `git push` if the host clone has credentials (SSH agent or stored remote URL).

If OpenHands cannot reach `forgejo` by name, ensure both services are on `arr-net` (`docker compose up -d forgejo openhands`).

**Forgejo** — http://192.168.8.123:3002  
If connection refused: crash-loop from dual SSH; compose uses `START_SSH_SERVER=false`. Recreate: `docker compose up -d forgejo --force-recreate`.

## Locals

Bound to loopback on the host (not LAN-reachable as published):

| Service | URL / path |
|---------|------------|
| SearXNG | http://127.0.0.1:8888 |

Open WebUI talks to SearXNG on the Docker network (`http://searxng:8080`); you only need the loopback URL for direct browser checks on the server.

### Manual config

**SearXNG** — None for normal use. Settings: `/opt/stack/searxng/settings.yml`. Secret comes from `.env` (`SEARXNG_SECRET`).

**WireGuard** — File only: `/opt/stack/wireguard/wg0.conf` (not a web UI). Must be ready before gluetun is healthy.

**Host shell** — `ssh tim@192.168.8.123` · stack logs: `docker compose -f /opt/stack/docker-compose.yml logs -f` · unit: `systemctl status arr-stack`.
