Volume Mounts

One persistent data root

The current official container uses a single persistent mount:

/data

It contains the SQLite database, imported media, and local backup archives.

The committed Compose setup uses a Docker named volume:

services:
  nostos:
    volumes:
      - nostos-data:/data

volumes:
  nostos-data:

Data layout

Inside the container:

/data/
├── nostos.db
├── books/
└── backups/

• nostos.db — SQLite library database and its SQLite sidecar files when present.
• books/ — stored book files, audiobook files, covers, thumbnails, and related generated book assets.
• backups/ — local .nostos backup archives.

Bind-mount alternative

If you prefer a visible host directory, you can replace the named volume with a bind mount:

volumes:
  - ./nostos-data:/data

Keep that directory on storage with reliable local filesystem semantics.

A live SQLite database should not be placed casually on network shares or cloud-sync folders. See Safe SQLite Storage for the reason.
