Customize php-fpm configuration in stable-fpm

[khartahk]

I'm trying to increase pm.max_children in stable-fpm but it's not working.
I've tried adding /usr/local/php-fpm.d/www2.conf with

[www]
pm.max_children = 100

But it doesn't appear to be working. Should this be done this way and I just don't know how to check for the effects or is there some other proper route?

I really don't want to copy the www.conf to my host config folder and override it by mounting the file in the same place as I don't want to risk breakage in the future.

What would be the proper way to do this?

Please try again with /usr/local/etc/php-fpm.d/www2.conf.

How can I verify it's working or where can I check out running php-fpm configuration?

@khartahk on my side the default was reached when trying to upload multiples files or a big files through the Web interface (Drag & Drop). If you reach the limit, then you should see something like that in the logs of the nextcloud container:

app_1    | [<Date removed>] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 8 children, there are 0 idle, and 6 total children

Above you can see that it spawn 8 children which is above the default value of ( (if I remember well).

How can I verify it's working or where can I check out running php-fpm configuration?

E.g. with https://www.php.net/manual/en/install.fpm.configuration.php#pm.status-path

@khartahk the solution of mounting additional file works, you can verify with running this command from the container:
php-fpm -tt

I guess the question has been answered. We just consume the base image from https://github.com/docker-library/php, so this is not specific to the Nextcloud image.
