Cronjobs¶

Um Cronjobs unter Nextcloud einzurichten, empfehlen wir Folgendes:

Stelle in dem Nextcloud Webinterface unter Administration-Settings -> Basic settings die Background jobs auf cron
Öffne den crontab auf dem Server mit folgendem Befehl: sudo crontab -e
Füge unten folgende Zeile ein: */5 * * * * docker exec -u www-data nextcloud-nextcloud-1 php -d memory_limit=-1 -f cron.php
