# Conjurer on Docker / Proxmox

Runbook for running Conjurer as Docker containers across Proxmox VMs:

| Component | VM | Container | Port | Image |
|-----------|----|-----------|------|-------|
| **Main bot** | VM-bot | `conjurer-bot` | 5000 (Flask comm) | `docker/Dockerfile.bot` |
| **Librarian** | VM-librarian | `conjurer-librarian` | 5001 | `docker/Dockerfile.librarian` |
| **Musician** | VM-musician | `conjurer-musician` | 5000 (+ radio) | `docker/Dockerfile.musician` |

The three talk to each other over HTTP on the Proxmox LAN. Direction of calls:

```
   bot  --(/mp3,/get_music,/add_to_priority,...)-->  musician
   bot  --(/query)-------------------------------->  librarian
musician --(/prepped_tracks)-------------------->    bot
librarian --(/conjurer results)----------------->    bot
```

Everything is configured through `CONJURER_*` environment variables (see the
`docker/env/*.env.example` files). Nothing is hardcoded to a host path anymore.

## 0. Prerequisites (per VM)

Create a small Linux VM in Proxmox (Debian 12 / Ubuntu 22.04+ is fine), then
install Docker:

```bash
sudo apt-get update && sudo apt-get install -y ca-certificates curl git
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker "$USER"   # log out/in afterwards
```

Clone the repo on each VM (they build from it):

```bash
sudo mkdir -p /opt && cd /opt
git clone https://github.com/migatu/conjurer.git
cd conjurer
```

> All `docker compose` commands below are run **from the repo root** (`/opt/conjurer`),
> because the compose files use `context: ..` relative to `docker/`.

---

## 1. Main bot (VM-bot)

### 1a. Prepare host directories

```bash
sudo mkdir -p /srv/conjurer/data /srv/conjurer/secrets
```

### 1b. Preserve existing command history  ⭐

The bot's conversation memory and settings live in JSON files. Copy them from
your current deployment (e.g. the Pi's `/home/pi/Conjurer/`) into the data
volume so the history carries over:

```bash
# run on the Pi, or scp the files across, then place them here:
sudo cp pamiec.json            /srv/conjurer/data/   # AI conversation history
sudo cp pamiec_muzyki.json     /srv/conjurer/data/   # music-DJ memory
sudo cp settings.json          /srv/conjurer/data/   # word/cyclic reactions
sudo cp system_gpt_settings.json /srv/conjurer/data/
sudo cp accident_log.json      /srv/conjurer/data/   # if present
```

If you skip this, the container starts with the (empty) template files baked
into the image and history begins fresh.

### 1c. Tokens

Drop your existing netrc (the one with `discord`, `openai`, `spotipy`,
`youtube` entries) into the secrets dir:

```bash
sudo cp ~/.netrc /srv/conjurer/secrets/.netrc
sudo chmod 600 /srv/conjurer/secrets/.netrc
```

(Alternatively skip netrc and set `DISCORD_TOKEN` / `OPENAI_API_KEY` in the env
file — those take precedence.)

### 1d. Configure and launch

```bash
cp docker/env/bot.env.example docker/env/bot.env
# edit docker/env/bot.env: set CONJURER_FILE_SERVICE / _LIBRARIAN_SERVICE to the
# other VMs' IPs, and CONJURER_API_KEY (same value on all three) if you want auth.

docker compose -f docker/compose.bot.yaml up -d --build
docker logs -f conjurer-bot
```

Look for `Loading … module done` for each cog, `Loading conanjurer commands
module done`, and `All systems: operational`.

---

## 2. Librarian (VM-librarian)

### 2a. Mount the DOI database

The librarian checks keyword hits from Crossref against a local database of
DOI chunk files (`0_chunk.txt … N_chunk.txt`). Put that database on the VM and
point the volume at it:

```bash
sudo mkdir -p /srv/librarian/doi /srv/librarian/secrets
# copy/replicate your chunk files into /srv/librarian/doi/
```

> The old Windows path `C:\Database\chunks\` is now `CONJURER_LIBRARIAN_DB_PATH`
> (defaults to `/doi/` in the container). `CONJURER_LIBRARIAN_MAXTHREADS` (41)
> and `CONJURER_LIBRARIAN_CHUNK` (`_chunk.txt`) are configurable too.

### 2b. Configure and launch

```bash
cp docker/env/librarian.env.example docker/env/librarian.env
# edit: CONJURER_MAIN_BOT=http://BOT_VM_IP:5000, CONJURER_CROSSREF_MAILTO, CONJURER_API_KEY

docker compose -f docker/compose.librarian.yaml up -d --build
docker logs -f conjurer-librarian
```

---

## 3. Musician (VM-musician) — you will adapt this

The web service is container-ready (`docker/Dockerfile.musician` +
`compose.musician.yaml`). Note it containerises the **Flask file/playlist
service only**; the Liquidsoap radio (`radio_conjurer.liq`) and any
Samba/NFS share tooling are separate and typically stay on the host or a
dedicated setup.

```bash
sudo mkdir -p /srv/musician/music /srv/musician/data
cp docker/env/musician.env.example docker/env/musician.env
# edit: CONJURER_MAIN_BOT=http://BOT_VM_IP:5000, CONJURER_API_KEY, mount your mp3s at /music

docker compose -f docker/compose.musician.yaml up -d --build
```

---

## 4. Networking & auth

- Open the ports between VMs on the Proxmox LAN: **bot 5000**, **librarian 5001**,
  **musician 5000** (+ radio harbor 54321 if used). A simple `ufw allow from
  <lan-subnet>` per port is enough; do not expose them to the internet.
- **Auth:** set the same `CONJURER_API_KEY` in all three `*.env` files. Then
  every internal call carries `X-Conjurer-Api-Key` and each service rejects
  requests without it (HTTP 401). Leave it empty everywhere to disable auth
  (fully backward compatible). ⚠️ Setting it on only one side breaks the link.
- The addresses point at each other by VM IP (or a DNS name). Set:
  - bot: `CONJURER_FILE_SERVICE`, `CONJURER_RADIO_HARBOR`, `CONJURER_LIBRARIAN_SERVICE`
  - librarian & musician: `CONJURER_MAIN_BOT`

---

## 5. Verify

```bash
# bot is up and reachable from another VM:
curl http://BOT_VM_IP:5000/conjurer            # -> "ALIVE"
# librarian answers:
curl http://LIBRARIAN_VM_IP:5001/ -I           # service reachable
docker ps            # all containers "Up"
docker logs conjurer-bot --tail 50
```

In Discord, exercise a command that round-trips through a service (e.g. a music
search that hits the musician, or a librarian query) to confirm the wiring and
the API key.

---

## 6. Updates

```bash
cd /opt/conjurer && git pull
docker compose -f docker/compose.bot.yaml up -d --build   # rebuild + restart
```

Data in `/srv/.../data` and `/doi` / `/music` volumes survives rebuilds, so
history and databases persist across updates.

---

## 7. Rollback / coexistence

- The native (Raspberry Pi / systemd) deployment is unaffected — none of the
  defaults changed; the container behaviour is opt-in via `CONJURER_DATA_DIR`
  and the other env vars. You can run both during migration.
- To roll back a VM: `docker compose -f docker/compose.<svc>.yaml down` and
  restart the previous deployment. The JSON state in `/srv/.../data` is plain
  files you can copy back to the Pi if needed.

---

## Notes on the images

- **Bot** uses the vendored `yt_dlp/` and `spotify_dl/` forks (they win over the
  pip packages because `/app` is first on `sys.path`), so your patches stay
  active without the old `sed` hacks from `install_main_bot.sh`.
- **Tectonic** (LaTeX `$latex` command) is installed best-effort; if the build
  step fails the bot still runs, just without LaTeX. Remove that layer from
  `Dockerfile.bot` if you don't need it.
- Voice needs `ffmpeg` + `libopus0` (both in the image). No microphone/pyaudio
  is required — voice is received over Discord and transcribed via AssemblyAI.
