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.
Pull the image and create a container. /docker can be anywhere on your host, this is just an example. Change MYSQL_ROOT_PASSWORD and MYSQL_PASSWORD values (mariadb). You may also want to change UID and GID for Nextcloud, as well as other variables (see Environment Variables).
docker pull wonderfall/nextcloud && docker pull mariadb
docker run -d --name db_nextcloud \
-v /docker/nextcloud/db:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=supersecretpassword \
-e MYSQL_DATABASE=nextcloud -e MYSQL_USER=nextcloud \
-e MYSQL_PASSWORD=supersecretpassword \
mariadb:10
docker run -d --name nextcloud \
--link db_nextcloud:db_nextcloud \
-v /docker/nextcloud/data:/data \
-v /docker/nextcloud/config:/config \
-v /docker/nextcloud/apps:/apps2 \
-v /docker/nextcloud/themes:/nextcloud/themes \
-e UID=1000 -e GID=1000 \
-e UPLOAD_MAX_SIZE=10G \
-e APC_SHM_SIZE=128M \
-e OPCACHE_MEM_SIZE=128 \
-e CRON_PERIOD=15m \

You are not obliged to use ADMIN_USER and ADMIN_PASSWORD. If these variables are not provided, you'll be able to configure your admin acccount from your browser.
In the admin panel, you should switch from AJAX cron to cron (system cron).
Pull a newer image, then recreate the container as you did before (Setup step). None of your data will be lost since you're using external volumes. If Nextcloud performed a full upgrade, your apps could be disabled, enable them again (starting with 12.0.x, your apps are automatically enabled after an upgrade).
I advise you to use docker-compose, which is a great tool for managing containers. You can create a docker-compose.yml with the following content (which must be adapted to your needs) and then run docker-compose up -d nextcloud-db, wait some 15 seconds for the database to come up, then run everything with docker-compose up -d, that's it! On subsequent runs, a single docker-compose up -d is sufficient!
Don't copy/paste without thinking! It is a model so you can see how to do it correctly.

You can update everything with docker-compose pull followed by docker-compose up -d.
Redis can be used for distributed and file locking cache, alongside with APCu (local cache), thus making Nextcloud even more faster. As PHP redis extension is already included, all you have to is to deploy a redis server (you can do as above with docker-compose) and bind it to nextcloud in your config.php file :
'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'memcache.local' => '\OC\Memcache\APCu',
'redis' => array(
'host' => 'redis',
'port' => 6379,
),
There is a script for that, so you shouldn't bother to log into the container, set the right permissions, and so on. Just use docker exec -ti nexcloud occ command.
