The page owns the shape, the first-run account step (ABS accepts the initial account only from a local-network address) and the laws: why the array bind is read-only and what the one-line rollback is if on-disk sidecars are ever wanted; why the metadata view is not that rollback; why the mount gate, the wget health check and the amd64 digest pin are each mandatory; and that LAN-only is a posture, not an accident. Media Audiobook Relayout gains the third reader: ABS stores absolute paths, so the relayout procedure has to reach its library too or it keeps rows for folders that are gone. The vault index is regenerated, not hand-carved.

# Audiobookshelf
|
|
|
|
Audiobookshelf (ABS) serves the [[Entropy Volume]] audiobook library to browsers
|
|
and phones: it scans `/mnt/entropy/Audiobooks`, keeps its own SQLite library with
|
|
per-listener playback positions, and streams the audio. It is **not** a media
|
|
server — it shares nothing with [[Plex]] or [[Jellyfin]] and owns no files on the
|
|
array.
|
|
|
|
**Host:** Dankserver — **Unit:** `audiobookshelf.service` (rootless Quadlet, user
|
|
manager) — **Internal-only:** LAN address, no vhost, no DNS name.
|
|
|
|
## Shape
|
|
|
|
| Item | Value |
|
|
|------|-------|
|
|
| Unit file | `dankserver/audiobookshelf/quadlet/audiobookshelf.container` (the authority for every number here) |
|
|
| Image | `ghcr.io/advplyr/audiobookshelf` pinned by **amd64 manifest digest** — see Laws |
|
|
| Port | `PublishPort=8000:8000` — web UI and API on the same port |
|
|
| Network | `pasta` (standalone; publishes nothing to other containers) |
|
|
| Audio bind | `/mnt/entropy/Audiobooks:/audiobooks:ro` — read-only, by design |
|
|
| State | `/home/dank/Containers/audiobookshelf/config` → `/config`, `…/metadata` → `/metadata` (both NVMe) |
|
|
| Mount gate | `ExecStartPre=…/wait-for-mount.sh /mnt/entropy` |
|
|
| Health | `wget` against `/healthcheck` inside the container, 30 s / 3 retries |
|
|
| I/O share | `IOWeight=10` — a scan loses the array to every other tenant |
|
|
| Self-healing | `Restart=always`, `RestartSec=5`, `WantedBy=default.target` |
|
|
| Deploy | `./scripts/deploy.sh dankserver --service audiobookshelf` |
|
|
| Handler | `deploy_audiobookshelf` in `scripts/deploy-remote.sh` |
|
|
|
|
## First run
|
|
|
|
1. Open `http://192.168.0.235:8000` **from the LAN**. ABS accepts the initial
|
|
account creation only from a local-network address; a remote address gets a
|
|
refusal, not a form.
|
|
2. Create the owner account, then add one **Audi Book** library with folder
|
|
`/audiobooks`. The path is the in-container name of the read-only bind.
|
|
3. The first scan reads the whole tree once. It runs in the background — the
|
|
deploy gate is already green by then, and `IOWeight=10` keeps it off the
|
|
critical path.
|
|
|
|
Nothing in this repo holds an ABS credential: the account is created in the
|
|
browser and lives in the `config` bind on the SSD.
|
|
|
|
## Laws
|
|
|
|
- **The audio bind stays `:ro`.** ABS writes nothing that belongs beside the
|
|
audio: its library, covers, progress and sidecar metadata all land in
|
|
`/metadata` on the SSD. A writable bind would put stray writes on the spindle
|
|
and hand the array to a service with no reason to hold it. If per-book
|
|
`.opf`/`.nfo` sidecars on disk are ever wanted, the rollback is one line —
|
|
point the audio bind at the [[Media Metadata View]] the media servers already
|
|
use — but that view's upper layer exists for those two servers' sidecars, so a
|
|
third writer needs a reason first ([[Media Metadata View]]).
|
|
- **Do not bind the raw array without the mount gate.** In a rootless unit
|
|
`ConditionPathIsMountPoint=` is fail-*dead* and `RequiresMountsFor=` is inert,
|
|
so a missing array does not stop the start: podman invents an empty directory,
|
|
ABS indexes it, and an empty library becomes recorded truth. `wait-for-mount.sh`
|
|
is the only gate that works here — same law the media servers obey
|
|
([[Quadlet Lifecycle]]).
|
|
- **The `HealthCmd` must use `wget`.** The image is Alpine and ships `wget`, not
|
|
`curl`; a `curl` health command reads a perfectly healthy server as unhealthy
|
|
and `Restart=always` turns that into a loop.
|
|
- **The image pin is the amd64 manifest digest, not the index digest.**
|
|
`podman inspect` reports the platform manifest (`RepoDigests[0]`) for what was
|
|
pulled, which differs from the manifest-list digest `latest` points at. Pin the
|
|
one this host runs. `latest` is newer than the newest version tag: upstream
|
|
stopped publishing version tags after `2.19.0` while `latest` kept moving, so
|
|
"highest version tag" is stale here — read the index, don't guess from tags.
|
|
- **`IOWeight=10` is inert without the host drop-ins.** `dankserver/host/systemd/`
|
|
carries `user.slice.d/io-accounting.conf` and the `user@1000` delegate, and the
|
|
deployer installs both; without them systemd silently drops the weight
|
|
([[Quadlet Lifecycle]]).
|
|
- **No `systemctl --user enable`.** Generated Quadlet units cannot be enabled on
|
|
this host; `WantedBy=default.target` in the unit file is what carries the
|
|
service across a reboot ([[Quadlet Lifecycle]]).
|
|
- **LAN-only until Frank says otherwise.** `0.0.0.0:8000` with no reverse proxy
|
|
in front. Any public vhost requires the Anubis + Authentik chain first, and the
|
|
outpost proxy provider has to exist before the vhost flips (external exposure
|
|
policy in `AGENTS.md`).
|
|
|
|
## Verification
|
|
|
|
`./tests/run.sh` covers this unit through `tests/dankserver_quadlet.bats`
|
|
(boot persistence, the SSD state roots, the `:ro` array bind, the mount gate, the
|
|
`wget` health check) and `tests/media_overlay.bats` (only [[Plex]] and
|
|
[[Jellyfin]] may reference the metadata view).
