Setting PHP memory_limit variable as a parameter in docker-compose

[michalpulpan]

Hi 👋 , first of all, thank you for an amazing work.

Some context - recently we started having some issues with memory in our Freescout instance (Allowed memory size of 2147483648 bytes exhausted (tried to allocate 5323576 bytes)).

So we tried to set memory_limit = 1024M in php.ini and php_admin_value[memory_limit] = 1024M in php-fpm.conf as stated in Freescout docs: https://github.com/freescout-help-desk/freescout/wiki/Installation-Guide#allowed-memory-size-of-nnn-bytes-exhausted-error-when-fetching-large-attachments. This helped solve the issue.
So we edited the files php.ini and php-fpm.conf locally and binded them into our containers into the path /etc/php82/. This is not perfect for many reasons 😄 .

My question is - is there some smarter way to define memory_limit param? Thanks!

Have a peek at the options that are also available in the image but not directly listed in the README:

Image Description
OS Base Customized Image based on Alpine Linux
Nginx Nginx webserver
PHP-FPM PHP Interpreter

In your case PHP_MEMORY_LIMIT would handle your needs..
