Build-time variables
- NEXTCLOUD_VERSION : version of nextcloud
- APCU_VERSION : version of apcu pecl ext
- APCUBC_VERSION : version of apcu_bc pecl ext
- GPG_nextcloud : fingerprint of the signing key
Environment variables
- UID : nextcloud user id (default : 991)
- GID : nextcloud group id (default : 991)
Volumes
- /data : nextcloud data.
- /config : configuration files.
- /apps2 : nextcloud downloaded apps.
Add the following code to your config.php in order to enable apps persistence :
"apps_paths" => array (
0 => array (
"path" => "/nextcloud/apps",
"url" => "/apps",
"writable" => false,
),
1 => array (
"path" => "/apps2",
"url" => "/apps2",
"writable" => true,
),
),
Database
You have to use an external database container. I suggest you to use MariaDB, which is a reliable database server. For example, you can use the official mariadb image available as an automated build that you can find on Docker Hub. Since sqlite is supected by Nextcloud to cause some troubles with sync clients, sqlite databases are not suported as they shouldn't be used.
Setup
Go to your fresh Nextcloud instance, change /nextcloud/data to /data (recommended), and fill in all the fields to configure your database. Don't forget to provide with a strong password. You should choose another name for the administration account (not 'admin' which is the default one). The database host is the name of the database container, which is linked to the nexcloud container. You can see below an example of docker-compose.
Configure
/config should contain config.php, though this is not the file actually used by Nextcloud. Each time you restart the container, /config/config.php overwrites /nextcloud/config/config.php. Before that, /nextcloud/config/config.php is copied as /nextcloud/config/config.php.bkp, so you can easily revert changes.
In the admin pannel, you should switch from AJAX cron to cron (system cron). By the way, I highly recommend encryption! Why not?
To enable APCU, add this line to your config.php :
'memcache.local' => '\OC\Memcache\APCu',
How do I update?
Just pull the newer image, and recreate the container.
Docker Compose (example)
nextcloud:
image: wonderfall/nextcloud
links:
- db_nextcloud:db_nextcloud
environment:
- UID=1000
- GID=1000
volumes:
- /mnt/nextcloud/data:/data
- /mnt/nextcloud/config:/config
- /mnt/nextcloud/apps:/apps2
db_nextcloud:
image: mariadb:10
volumes:
- /mnt/nextcloud/db:/var/lib/mysql
environment:
- MYSQL_ROOT_PASSWORD=supersecretpassword
- MYSQL_DATABASE=nextcloud
- MYSQL_USER=nextcloud
- MYSQL_PASSWORD=supersecretpassword
Port
- 80.
Reverse proxy

Headers are already sent by the container. It is strongly recommended to use Nextcloud through an encrypted connection (HTTPS).
