cron missing in image

[tzerber]

There's no need to build a custom image. There are numerous ways of addressing this, but the simplest approach is a cron job on the host.

E.g. nextcloud/previewgenerator#176 (comment)

To extend this reply:
Most docker instances nowadays have a separated "cron" container that offloads the cron jobs since some of those are quite intensive and can block the PHP proccess for long time.

That container is basically the same NC instance that uses the cron.sh docker entrypoint.
Instead of using the applications's container, a more "portable" solution is to use the cron container and/or it's crontab.

To do so : instead of using the main container name, use the cron container name to execute the same task, for example (copied from link above) 0 22 * * * root cd /docker/nextcloud/ && /usr/local/bin/docker-compose exec -T --user www-data cron php occ preview:pre-generate.

Other options include mounting the file /var/spool/cron/crontabs/www-data as volume, and putting the desired crontab entries there. With recent including of the watch parameters of Docker, you don't need to do anything additional.

Okay, thank you for clearing that up :)
