8000: HTTP port
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:
docker compose up -d
docker compose logs -fYou can also use the following minimal command:
docker run -d -p 8000:8000 --name nextcloud \
-v "$(pwd)/data:/data" \
crazymax/nextcloud:latestTo 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 -dIf 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 compose exec nextcloud occIf you want to enable the cronjob, you have to run a "sidecar" container (see cron service in compose.yml example) or run a simple container like this:
docker run -d --name nextcloud_cron \
--env-file $(pwd)/nextcloud.env \
-e "SIDECAR_CRON=1" \
-e "CRON_PERIOD=*/5 * * * *" \
-v "$(pwd)/data:/data" \
crazymax/nextcloud:latestAnd do not forget to choose Cron as background jobs:
To execute pre-generation of previews through the Preview Generator plugin, you have to run a "sidecar" container (see cron service in compose.yml example) or run a simple container like this:
docker run -d --name nextcloud_previewgen \
--env-file $(pwd)/nextcloud.env \
-e "SIDECAR_PREVIEWGEN=1" \
-e "PREVIEWGEN_PERIOD=0 * * * *" \
-v "$(pwd)/data:/data" \
crazymax/nextcloud:latestIf you want to enable the Nextcloud News Updater, you have to run a "sidecar" container (see news_updater service in compose.yml example) or run a simple container like this:
docker run -d --name nextcloud_news_updater \
--env-file $(pwd)/nextcloud.env \
-e "SIDECAR_NEWSUPDATER=1" \
-e "NC_NEWSUPDATER_THREADS=10" \
-e "NC_NEWSUPDATER_TIMEOUT=300" \
-e "NC_NEWSUPDATER_INTERVAL=900" \
-e "NC_NEWSUPDATER_LOGLEVEL=error" \
-v "$(pwd)/data:/data" \
crazymax/nextcloud:latestAnd do not forget to disable Use system cron for updates in news settings:
You can use our SMTP relay msmtpd service published on port 2500 and
declared in our compose.yml:
Redis is recommended, alongside APCu to make Nextcloud faster. If you want to
enable Redis, deploy a redis container (see 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,
),
If you want to access your Nextcloud installation in a subdir (like
/nextcloud), you have to set the SUBDIR environment variable and also add
PathPrefixStrip:/nextcloud to your frontend rule if you use Traefik. Do not
forget to remove includeSubDomains option in HSTS_HEADER if used.
