php.iniis.When I got the warning that the
apc.shm_sizeis almost full It took me a long time to figure out how to cleanly fix it in docker and where the config PHP is stored.And which file was the right one to edit this option?
And which file was the right one to edit this option?
I added the line
apc.shm_size=128M
to the file
/etc/php/8.2/cli/conf.d/20-apcu.ini
did a
systemctl restart php8.2-fpm.service
and the warning disappeared. It would have been really nice if there had been a note about this somewhere.I get this warning now too. This would be really nice if its configurable as a environment variable.
When I got the warning that the
apc.shm_sizeis almost full It took me a long time to figure out how to cleanly fix it in docker and where the config PHP is stored.It feels a bit odd to me that a setting that the docs recommend to change requires me to figure out where the PHP config dir is and add a file to it.
I would suggest adding a
PHP_APC_SHM_SIZEenvironment variable similar toPHP_UPLOAD_LIMIT.
