+> Cron container image.
+
+## Description
+
+This container periodically runs the slapd backup script. The script runs in the
+slapd container so the `dockerd` socket is bind mounted to this container and
+the commands are executed via `docker exec` in the other containers. Thus,
+outside of the context of this setup this container doesn't make much sense.
