Is it possible/safe to install Client Push App ?

[mononym]

Hello. Short question: I wonder if I can install the Client Push App, as described in https://github.com/nextcloud/notify_push ? Basically, does the setup work when running sudo -u www-data php -f /app/code/occ notify_push:setup. Thx

Hello @mononym

You can always create a clone from your latest backup and tinker with the clone.
With that approach you risk nothing and can report findings.

@james unfortunately that's not possible because of storage capacity. All data is on the primary storage. I'll maybe give it a try after a regular backup.

You can always play in the demo cloudron

I don’t think this is possible within Cloudron. For push to work, you need to create a daemon at /etc/systemd/system/notify_push.service and make some changes to Apache or Nginx.
The occ notify_push:setup command assumes that all of this is done on the same server where Nextcloud itself is installed.
However, based on the information from https://github.com/nextcloud/notify_push, it seems that it might be possible to set it up on a separate server — though exactly how to do that is another question.

Thanks. I started guessing the same while trimming through the repo. If I'm not mistaken, moving towards Nextcloud All-in-one would integrate this in the NC packge. Meanwhile, good to know that changes on the server are not immediately pushed to the clients.

I've been following the instructions in threads cited below, and it looks like notify_push is up and running

1. configure nginx https://forum.cloudron.io/post/48343
2. run notify_push via script https://forum.cloudron.io/post/48298

I honestly don’t understand how you managed to get this working. I spent about 5 hours today trying to set it up and still didn’t get the result I expected.

1. @reboot cron job simply doesn’t work. It’s mentioned in the docs but I’ve never seen it run in the logs. @service does run but only once. Аfter subsequent Nextcloud restarts the job never triggers again.
2. My version of the script works fine if I run it manually from the terminal like this /app/data/notify_push.sh. The service starts and all checks pass.

root@71780ea5-011c-4c09-886e-5f7e17e0b670:/app/code# /app/data/notify_push.sh ; sleep 1 ; ps aux | grep notify_push ; ss -tlnp | grep 7867

3. If I set up a cron job to run every 5 minutes.
   */5 * * * * echo "=> Enabling notify_push" && /app/data/notify_push.sh
   I can see in the logs that everything looks fine:

Apr 16 18:30:41 ✓ redis is configured
Apr 16 18:30:41 ✓ push server is receiving redis messages
Apr 16 18:30:41 ✓ push server can load mount info from database

Apr 16 18:30:41 configuration saved
Apr 16 18:30:41 => notify_push started on port 7867

But in reality the process doesn’t survive after the script finishes. If I check manually with
ps aux | grep notify_push ; ss -tlnp | grep 7867 there’s nothing in the terminal.

Claude suggested this might be a cgroup-related issue in containers. The process started from cron gets attached to its cgroup and when the cron job exits, the process is killed along with it. I’m not sure how accurate that is.

Maybe most people who claimed to have notify_push working probably didn’t verify it properly, since the warning disappears from the Nextcloud admin panel. It looks like it’s working, even when it actually isn’t.
