Quick Start

[!TIP] For OIDC setup, advanced configuration, or upgrade guides, see the full documentation.

Requirements: Docker and Docker Compose.

Image Repositories

Registry	Image
Docker Hub	grimmory/grimmory
GitHub Container Registry	ghcr.io/grimmory-tools/grimmory

Step 1: Environment Configuration

Create a .env file:

# Application
APP_USER_ID=1000
APP_GROUP_ID=1000
TZ=Etc/UTC

# Database
DATABASE_URL=jdbc:mariadb://mariadb:3306/grimmory
DB_USER=grimmory
DB_PASSWORD=ChangeMe_Grimmory_2025!

# Optional: enable API docs + export OpenAPI JSON (defaults to false)
API_DOCS_ENABLED=false

# Storage: LOCAL (default) or NETWORK (disables file operations; see Network Storage section)
DISK_TYPE=LOCAL

# MariaDB
DB_USER_ID=1000
DB_GROUP_ID=1000
MYSQL_ROOT_PASSWORD=ChangeMe_MariaDBRoot_2025!
MYSQL_DATABASE=grimmory

Step 2: Docker Compose

Stable images are published from semantic-release tags on main as vX.Y.Z plus latest. Nightly images are built from develop and tagged nightly.

[!NOTE] Migrating from an existing Booklore container? You can keep your current service name, container_name, database name and user, ports, and mounted volumes the same. Replace only the image: line with grimmory/grimmory:<tag> or ghcr.io/grimmory-tools/grimmory:<tag>.

services:
  booklore:
    image: grimmory/grimmory:v2.2.1

Create a docker-compose.yml or copy and adapt deploy/compose/docker-compose.yml:

services:
  grimmory:
    image: grimmory/grimmory:latest
    # Convenience tag:
    # image: grimmory/grimmory:<release-version>
    # Alternative: ghcr.io/grimmory-tools/grimmory:<release-version>
    # To build from source instead: comment out 'image' and uncomment below
    # build: .
    container_name: grimmory
    environment:
      - USER_ID=${APP_USER_ID}
      - GROUP_ID=${APP_GROUP_ID}
      - TZ=${TZ}
      - DATABASE_URL=${DATABASE_URL}
      - DATABASE_USERNAME=${DB_USER}
      - DATABASE_PASSWORD=${DB_PASSWORD}
      - API_DOCS_ENABLED=${API_DOCS_ENABLED}
      - DISK_TYPE=${DISK_TYPE}
    depends_on:
      mariadb:
        condition: service_healthy
    ports:
      - "6060:6060"
    volumes:
      - ./data:/app/data
      - ./books:/books
      - ./bookdrop:/bookdrop
    healthcheck:
      test: wget -q -O - http://localhost:6060/api/v1/healthcheck
      interval: 60s
      retries: 5
      start_period: 60s
      timeout: 10s
    restart: unless-stopped

  mariadb:
    image: lscr.io/linuxserver/mariadb:11.4.5
    container_name: mariadb
    environment:
      - PUID=${DB_USER_ID}
      - PGID=${DB_GROUP_ID}
      - TZ=${TZ}
      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
      - MYSQL_DATABASE=${MYSQL_DATABASE}
      - MYSQL_USER=${DB_USER}
      - MYSQL_PASSWORD=${DB_PASSWORD}
    volumes:
      - ./mariadb/config:/config
    restart: unless-stopped
    healthcheck:
      test: ["CMD", "mariadb-admin", "ping", "-h", "localhost"]
      interval: 5s
      timeout: 5s
      retries: 10

Step 3: Launch

docker compose up -d

Open http://localhost:6060, create your admin account, and start building your library.

Additional deployment examples:

• Docker Compose: deploy/compose/docker-compose.yml
• Helm: deploy/helm/grimmory/Chart.yaml
• Podman Quadlet: deploy/podman/quadlet/README.md

Developer Surfaces

Contributor workflow, PR policy, and release semantics live in CONTRIBUTING.md.

General purpose development guidelines live in DEVELOPMENT.md. Component-specific implementation guidance lives in:

• booklore-api/DEVELOPMENT.md
• frontend/DEVELOPMENT.md

The root Justfile is the primary local command surface and mirrors the folder-local booklore-api/Justfile and frontend/Justfile entrypoints.

just               # Show root + api + ui recipes
just test          # Run backend and frontend tests
just api test      # Run backend tests only
just ui dev        # Start the frontend dev server

---

API Reference Docs

When enabled via API_DOCS_ENABLED, API reference documentation is available as both an openapi.json and as publicly accessible docs. The endpoints are:

• API reference docs are available at http://localhost:6060/api/docs
• OpenAPI JSON is available at http://localhost:6060/api/openapi.json

---

BookDrop

Drop book files into a watched folder. Grimmory picks them up, pulls metadata, and queues them for your review.

graph LR
    A[Drop Files] --> B[Auto-Detect]
    B --> C[Extract Metadata]
    C --> D[Review and Import]

Step	What Happens
1. Watch	Grimmory monitors the BookDrop folder continuously
2. Detect	New files are picked up and parsed automatically
3. Enrich	Metadata is fetched from Google Books and Open Library
4. Import	You review, adjust if needed, and add to your library

Mount the volume in docker-compose.yml:

volumes:
  - ./bookdrop:/bookdrop

---

Network Storage

Set DISK_TYPE=NETWORK in your .env to run Grimmory against a network-mounted file system (NFS, SMB, etc.). In this mode, direct file operations (delete, move, rename from the UI) are disabled to avoid destructive changes on shared mounts. All other features — reading, metadata, sync — remain fully functional.
