TZ: The timezone assigned to the container (defaultUTC)MEMORY_LIMIT: PHP memory limit (default512M)UPLOAD_MAX_SIZE: Upload max size (default512M)OPCACHE_MEM_SIZE: PHP OpCache memory consumption (default128)APC_SHM_SIZE: APCu memory size (default128M)HSTS_HEADER: HTTP Strict Transport Security header value (defaultmax-age=15768000; includeSubDomains)RP_HEADER: Referrer Policy header value (defaultstrict-origin)DB_TYPE: Database type (mysql, pgsql or sqlite) (defaultsqlite)DB_NAME: Database name (defaultnextcloud)DB_USER: Username for database (defaultnextcloud)DB_PASSWORD: Password for database user (defaultasupersecretpassword)DB_HOST: Database host (defaultdb)

Docker compose is the recommended way to run this image. Copy the content of folder examples/compose in /var/nextcloud/ on your host for example. Edit the compose and env files with your preferences and run the following commands :
touch acme.json
chmod 600 acme.json
docker-compose up -d
docker-compose logs -fYou can also use the following minimal command :
docker run -d -p 80:80 --name nextcloud \
-v $(pwd)/data:/data \
crazymax/nextcloud:latestIf you run the container for the first time, the installation will be automatic using the DB_* environment variables.
Then open your browser to configure your admin account.
If you want to use the occ command to perform common server operations like manage users, encryption, passwords, LDAP setting, and more, type :
docker exec -ti nextcloud occIf you want to enable the cron job, you have to run a "sidecar" container like in the docker-compose file or run a simple container like this :
docker run -d --name nextcloud-cron \
--env-file $(pwd)/nextcloud.env \
-e CRON_PERIOD=*/15 * * * * \
-v $(pwd)/data:/data \
crazymax/nextcloud:latest /usr/local/bin/cronThen do not forget to choose Cron as background jobs :
Do not forget to configure your Email server settings with your preferences :
Redis is recommended, alongside APCu to make Nextcloud more faster.
If you want to enable Redis, deploy a redis container (see docker-compose file) and add this to your config.php :
'memcache.local' => '\OC\Memcache\APCu',
'memcache.distributed' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',
'redis' => array(
'host' => 'redis',
'port' => 6379,
),
To upgrade to the latest version of Nextcloud, pull the newer image and launch the container. Nextcloud will upgrade automatically :
docker-compose pull
docker-compose up -dAll kinds of contributions are welcome 🙌!
