## Service / port map

| Service | Listen | Notes |
|---------|--------|-------|
| Grimmory | `192.168.8.247:6060` | Docker Compose at `/opt/grimmory/` |
| MariaDB | internal only | Sidecar in the same compose stack |

## Compose

Located at `/opt/grimmory/docker-compose.yml`. Key points:

- Image: `ghcr.io/grimmory-tools/grimmory:latest`
- Books library: `/mnt/library/books` → `/books` (read-write; media GID 10000 via `GROUP_ID=10000`)
- Bookdrop (watched folder for auto-import): `/opt/grimmory/bookdrop` → `/bookdrop`
- App data (covers, DB config): `/opt/grimmory/data` → `/app/data`
- MariaDB config: `/opt/grimmory/mariadb/config` → `/config` (linuxserver/mariadb image)
- `extra_hosts: auth.hubris.network:192.168.8.175` — routes Authentik OIDC discovery to Caddy from inside the container
- `FORCE_DISABLE_OIDC=false` — OIDC stays enabled; provider configured via Grimmory admin UI

Credentials live in `/opt/grimmory/.env` (untracked):
- `DATABASE_PASSWORD` / `MYSQL_PASSWORD` — MariaDB Grimmory user password
- `MYSQL_ROOT_PASSWORD` — MariaDB root password

## Authentik OIDC

Uses Confidential client (client secret stored in Grimmory's DB — migrated from Booklore). The OIDC config carried over in the database dump; no manual re-entry needed.

- **Authentik provider:** `Provider for Grimmory` (renamed from `Provider for Booklore` on migration)
- **Client ID:** `L1u0eFsNhbKgiIvvFeIr2mvZdbtFyzidCq2h6thL`
- **Client type:** Confidential (client secret in `oidc_provider_details` in MariaDB `app_settings`)
- **Redirect URI:** `https://books.hubris.network/oauth2-callback`
- **Scopes:** openid, profile, email, offline_access
- **Back-channel logout:** `http://192.168.8.247:6060/api/v1/auth/oidc/backchannel-logout`
- **Application slug:** `booklore` → Issuer URI: `https://auth.hubris.network/application/o/booklore/`

## Media permissions

LXC is privileged → in-container UID = host UID. Docker container gets media GID via `GROUP_ID=10000` env var (Grimmory/linuxserver pattern). The `/mnt/library/books` subtree is owned `:media` mode `2775` (setgid). See [media-permissions](../infrastructure/media-permissions.md).

## Changelog

### 2026-06-29 — provisioned; Booklore migrated

MariaDB dump from Booklore (LXC 105) restored — schema-compatible since Grimmory is a direct fork. Caddy `books.hubris.network` backend updated from `192.168.8.205:6060` to `192.168.8.213:6060`. Authentik provider updated: Booklore → Grimmory, Confidential → Public (PKCE). Booklore stack removed from Portainer on LXC 105.
