bookstack_db_root_password, bookstack_db_password and
bookstack_admin_password shipped as real strings in defaults, despite
the comment two lines above promising 'empty defaults force assert to
fail until set'. The Validate task in tasks/main.yml asserts each is
non-empty, so set them to '' and let the assert do its job.
Mirror the docstring comment to show how to generate each one with
openssl rand.
Deploy BookStack with linuxserver.io images behind Traefik, including
Entra ID OIDC SSO support and a daily backup timer.
Stack:
- lscr.io/linuxserver/bookstack:version-v26.03.3
- lscr.io/linuxserver/mariadb:11.4.9
- Traefik labels for websecure entrypoint on internal network
- Healthcheck via mariadb-admin ping (LSIO image lacks healthcheck.sh)
Features:
- Persistent APP_KEY generated on first run, stored in volume dir
- Optional OIDC SSO via Microsoft Entra ID (configurable per-instance)
- Idempotent admin user creation with DB-based existence check
- Daily systemd timer backup (DB dump + uploads tar + APP_KEY)
with configurable retention
Implementation notes:
- DB queries use --protocol=tcp with the app user because root@localhost
uses unix_socket auth in the LSIO MariaDB image (no password) and
root@% does not exist
- docker_container_exec uses argv: (list) instead of command: (string)
to avoid argument-splitting issues
- Migration-wait task ensures users table exists before admin check,
since /login returns 200 before Laravel migrations complete
- no_log: true on all tasks that reference DB or admin passwords
- artisan absolute path (/app/www/artisan) because LSIO image WORKDIR
is not the app directory
Adds bookstack route to DMZ Traefik service registry.
