 A script , or "agent", to assess the health of the MariaDB container has been added to the *local image* via the *Dockerfile*. In other words, the script is specific to IOTstack.
 
 Because it is an instance of MariaDB, Nextcloud_DB inherits the health-check agent. See the [IOTstack MariaDB](MariaDB.md) documentation for more information.
