# Plan: Migrate Booklore → Grimmory (LXC 130)

**Status:** in-progress  
**Date:** 2026-06-29  
**Goal:** Replace Booklore on shared apps LXC 105 with Grimmory on a dedicated LXC 130. Grimmory is the community fork/successor of Booklore with the same database schema and port, so the migration is a near-drop-in swap.

---

## Pre-flight checklist

- [ ] Note Booklore MariaDB credentials from Portainer compose on LXC 105 (`DATABASE_PASSWORD`, `MYSQL_ROOT_PASSWORD`)
- [ ] Confirm `/mnt/library/books` is readable on LXC 105 (`ls /mnt/library/books | head`)

---

## Step 1 — Dump Booklore MariaDB

```bash
# On hubris — find the MariaDB container name
pct exec 105 -- docker ps --format '{{.Names}}' | grep -i maria

# Dump (replace <CONTAINER> and <PASSWORD> from Portainer compose)
pct exec 105 -- docker exec <CONTAINER> \
  mysqldump -u grimmory -p<PASSWORD> grimmory \
  > /tmp/booklore-$(date +%Y%m%d).sql

# Pull to hubris root for safekeeping
pct pull 105 /tmp/booklore-$(date +%Y%m%d).sql /root/
```

---

## Step 2 — Create LXC 130

```bash
# On hubris — list available Debian 13 templates
pveam list local | grep debian-13

# Create LXC
pct create 130 local:vztmpl/debian-13-standard_13.0-1_amd64.tar.zst \
  --hostname grimmory \
  --ostype debian \
  --unprivileged 0 \
  --cores 1 --memory 2048 --rootfs local-lvm:16 \
  --net0 name=eth0,bridge=vmbr0,ip=dhcp \
  --onboot 1 \
  --mp0 /mnt/library,mp=/mnt/library \
  --features nesting=1

pct start 130
pct exec 130 -- apt-get update -qq
```

Set the static IP directly in PVE (same pattern as all other LXCs — no Fritz!Box reservation needed):
```bash
pct set 130 --net0 name=eth0,bridge=vmbr0,ip=192.168.8.213/24,gw=192.168.8.1
pct reboot 130
```

---

## Step 3 — Bootstrap LXC 130

```bash
pct exec 130 -- bash -c '
  # Media group
  groupadd -g 10000 media

  # Docker
  apt-get install -y ca-certificates curl
  curl -fsSL https://get.docker.com | sh
  systemctl enable --now docker
'
```

---

## Step 4 — Deploy Grimmory compose

```bash
pct exec 130 -- mkdir -p /opt/grimmory/mariadb/config /opt/grimmory/data /opt/grimmory/bookdrop
```

Write `/opt/grimmory/docker-compose.yml` on LXC 130:

```yaml
services:
  grimmory:
    image: ghcr.io/grimmory-tools/grimmory:latest
    container_name: grimmory
    restart: unless-stopped
    ports:
      - "192.168.8.213:6060:6060"
    volumes:
      - ./data:/app/data
      - /mnt/library/books:/books
      - ./bookdrop:/bookdrop
    environment:
      - DATABASE_URL=jdbc:mariadb://mariadb:3306/grimmory
      - DATABASE_USERNAME=grimmory
      - DATABASE_PASSWORD=${GRIMMORY_DB_PASSWORD}
      - USER_ID=0
      - GROUP_ID=10000
      - TZ=Europe/Berlin
      - FORCE_DISABLE_OIDC=false
    extra_hosts:
      - "auth.hubris.network:192.168.8.175"
    depends_on:
      mariadb:
        condition: service_healthy

  mariadb:
    image: lscr.io/linuxserver/mariadb:11.4.8
    container_name: grimmory-mariadb
    restart: unless-stopped
    volumes:
      - ./mariadb/config:/config
    environment:
      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
      - MYSQL_DATABASE=grimmory
      - MYSQL_USER=grimmory
      - MYSQL_PASSWORD=${GRIMMORY_DB_PASSWORD}
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "localhost"]
      interval: 10s
      timeout: 5s
      retries: 5
```

Write `/opt/grimmory/.env` on LXC 130 (fill real passwords):
```
GRIMMORY_DB_PASSWORD=<same_password_as_booklore>
MYSQL_ROOT_PASSWORD=<root_password>
```

Start:
```bash
pct exec 130 -- bash -c 'cd /opt/grimmory && docker compose up -d mariadb'
# wait ~15s for MariaDB to init, then start grimmory
pct exec 130 -- bash -c 'cd /opt/grimmory && docker compose up -d'
```

Verify Grimmory responds (before DB restore — will show setup wizard):
```bash
curl -s -o /dev/null -w '%{http_code}' http://192.168.8.213:6060
# expect 200 or 302
```

---

## Step 5 — Restore Booklore DB

```bash
# Stop Grimmory (keep MariaDB running)
pct exec 130 -- docker stop grimmory

# Copy dump to LXC 130
pct push 130 /root/booklore-$(date +%Y%m%d).sql /tmp/booklore.sql

# Restore (replace <PASSWORD>)
pct exec 130 -- docker exec -i grimmory-mariadb \
  mysql -u grimmory -p<GRIMMORY_DB_PASSWORD> grimmory \
  < /tmp/booklore.sql

# Restart Grimmory
pct exec 130 -- docker start grimmory
```

Verify books appear:
```bash
curl -s http://192.168.8.213:6060 | grep -i grimmory
```

---

## Step 6 — Authentik OIDC update

In Authentik Admin UI (`https://auth.hubris.network`):

1. Providers → find `Booklore` provider
2. Edit:
   - Name: `Grimmory`
   - Client Type: **Public** (Grimmory uses PKCE — no secret needed)
   - Redirect URIs: `https://books.hubris.network/oauth2-callback`
   - Scopes: openid, profile, email, offline_access
   - Back-channel logout URL: `http://192.168.8.213:6060/api/v1/auth/oidc/backchannel-logout`
3. Note the **Client ID** and **Application slug** for Grimmory's OIDC settings

In Grimmory Admin UI (`http://192.168.8.213:6060` → Settings → Authentication → OIDC):
- Issuer URI: `https://auth.hubris.network/application/o/<slug>/` (trailing slash required!)
- Client ID: (from Authentik)
- Client Secret: leave blank (PKCE)
- Click **Test Connection** — all checks should pass (container reaches Authentik via extra_hosts)

---

## Step 7 — Caddy cutover

In the `dtoro/caddy-conf` repo, update `books.hubris.network`:

```caddy
books.hubris.network {
  reverse_proxy 192.168.8.213:6060
}
```

Git push → Caddy webhook auto-reloads (see [caddy (121)](../../knowledge/wiki/containers/121-caddy.md)).

Test:
```bash
curl -s -o /dev/null -w '%{http_code}\n' https://books.hubris.network
```

---

## Step 8 — Enroll as homelab client

```bash
homelab client add grimmory --lan-ip 192.168.8.213
```

Commits the `age_pubkey` back to `inventory.yaml`.

---

## Step 9 — Verify end-to-end

- [ ] `https://books.hubris.network` loads Grimmory
- [ ] OIDC login via Authentik works
- [ ] Library books from `/mnt/library/books` are visible
- [ ] Reading progress / metadata from Booklore is present

---

## Step 10 — Decommission Booklore on LXC 105

1. Portainer → navigate to the Booklore stack → Stop → Remove
2. Keep the dump at `/root/booklore-<date>.sql` on hubris (or archive to `/mnt/library/documents/`)

---

## Rollback

If something goes wrong before Caddy cutover: no user-visible impact, just shut down LXC 130.

If Caddy already cut over: revert the `books.hubris.network` block to `192.168.8.205:6060` and push. Booklore still running on LXC 105 until Portainer stack is removed.
