Steps To Reproduce

When using serversideup/php:8.3-fpm after v3.4.0 release I've got an error on starting container:

31 line is

process_control_timeout = ${PHP_FPM_PROCESS_CONTROL_TIMEOUT}

Looks like this variable defined only for fpm-apache and fpm-nginx variants, but not for vanilla fpm (and other images). So it’s better to define default value for all images?

Outcome

What did you expect?

Container started

What happened instead?

Container can't start

Affected Docker Images

serversideup/php:8.3-fpm

Anything else?
