 ### Database
 Basically, you can use a database instance running on the host or any other machine. An easier solution is to use an external database container. I suggest you to use MariaDB, which is a reliable database server. You can use the official `mariadb` image available on Docker Hub to create a database container, which must be linked to the Nextcloud container. PostgreSQL can also be used as well.
