 ### How to change the default location of Nextcloud's Datadir?
 You can configure the Nextcloud container to use a specific directory on your host as data directory. You can do so by adding the environmental variable `NEXTCLOUD_DATADIR` to the initial startup of the mastercontainer. Allowed values for that variable are strings that start with `/` and are not equal to `/`.

 ### How to allow the Nextcloud container to access directories on the host?
 By default, the Nextcloud container is confined and cannot access directories on the host OS. You might want to change this when you are planning to use local external storage in Nextcloud to store some files outside the data directory and can do so by adding the environmental variable `NEXTCLOUD_MOUNT` to the initial startup of the mastercontainer. Allowed values for that variable are strings that start with `/` and are not equal to `/`.
