This image was made for my own use and I have no intention to make this official. Support won't be regular so if there's an update, or a fix, you can open a pull request. Any contribution is welcome, but please be aware I'm very busy currently. Before opening an issue, please check if there's already one related. Also please use Github instead of Docker Hub, otherwise I won't see your comments. Thanks.

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_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:10.0 && docker pull mariadb:10 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 \ -e TZ=Etc/UTC \ -e ADMIN_USER=mrrobot \ -e ADMIN_PASSWORD=supercomplicatedpassword \ -e DOMAIN=cloud.example.com \ -e DB_TYPE=mysql \ -e DB_NAME=nextcloud \ -e DB_USER=nextcloud \ -e DB_PASSWORD=supersecretpassword \ -e DB_HOST=db_nextcloud \ wonderfall/nextcloud:10.0
You are not obliged to use
ADMIN_PASSWORD. If these variables are not provided, you'll be able to configure your admin acccount from your browser.
Below you can find a docker-compose file, which is very useful!
Now you have to use a reverse proxy in order to access to your container through Internet, steps and details are available at the end of the README.md. And that's it! Since you already configured Nextcloud through setting environment variables, there's no setup page.
You will have to build yourself using an Alpine-ARM image, like
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.
How to configure Redis
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, ),
How to configure Nextant
You will have to deploy a Solr server, I've shown an example above with docker-compose. Once Nextant app is installed, go to "additional settings" in your admin pannel and use http://solr:8983/solr as "Adress of your Solr Servlet". There you go!
Tip : how to use occ command
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.
Of course you can use your own software! nginx, Haproxy, Caddy, h2o, Traefik...
The latter is especially a good choice when using Docker. Give it a try!
Whatever your choice is, you have to know that headers are already sent by the container, including HSTS, so there's no need to add them again. It is strongly recommended (I'd like to say : MANDATORY) to use Nextcloud through an encrypted connection (HTTPS). Let's Encrypt provides free SSL/TLS certificates, so you have no excuses.
