Configuring Nextcloud Cron jobs in TrueNAS SCALE

Hello all,

First of all my apolagies for whom might find that the answer to my question is already out there, and that I simply have not looked hard enough… I can assure you I have spend numerous hours looking for a solution, without any luck.

I am running official Nextcloud 29.0.0, Chart Version:2.0.2 on TrueNAS-SCALE-23.10.2.

Nextcloud is running just fine, using an “SMB/CIFS” “External storage”. However I am looking into implementing some cron jobs, and have no clue how to do so. Cron does seem to be running, as I have selected it when installing the app.

Can anyone assist me in adding a Nextcloud cron job? I did find some documentation using docker, but docker commands are not recognized?

Thanks in advance,


To see if cron is running properley, click on your photo / icon at the top right corner of your Nextcloud webpage. From there, click “Administration settings”, and a security and setup warnings page will be displayed, including commenting on your cron.

Hopefully you get the nice green tick!

Thanks, cron is running.

Now only to add cron jobs…

System Settings → Advanced, see the section to add them there.

That wouldn’t add cron jobs inside the Nextcloud app.

Nextcloud is supposed to enable the standard job (maintenance of stuff) automatically if you select cron (Recommended). They used to have a bug in the IX app for this but it was resolved long ago. But he does have the green tick. If you want other cron jobs other than the background nextcloud created one (which OP says he does), I find it much easier to schedule outside of Nextcloud, i.e., simply have it run the command(s) or script inside the container. More visible, etc. So, I still use the UI for that. YMMV.

But the OP mentions docker commands, still indicating he wants to outside of the container. Docker is not there, like virtually all “guides”, out of date. The way you do that is like this (example):

k3s kubectl exec -n ix-nextcloud --stdin --tty "$(/usr/local/bin/k3s kubectl -n ix-nextcloud get pods --field-selector status.phase=Running -o name | cut -f2 -d'/')" -- su -s /bin/bash www-data -c 'php occ maintenance:mode --on'

You can replace the’php occ maintenance:mode --on’ command with whatever you want to run within the container.


Thanks @sfatula . I’ll give that a go!

Let me know if any trouble.

Hello @sfatula, took a while before I found the time to test it. I assume the problem is that Truenas has 3 Nextcloud pods running.

Error from server (NotFound): pods "nextcloud-redis-74444979dc-jgktt\nnextcloud-postgres-6779b848-sbw8b\nnextcloud-6d4b74cd88-4qs9d" not found

Also running the command with the pod name entered manually gives me the following.

# Linux truenas 6.1.74-production+truenas #2 SMP PREEMPT_DYNAMIC Wed Feb 21 20:30:38 UTC 2024 x86_64
