setting PHP_FPM_ENV_VARS does not have effect on non-dev images

[serhatozkara]

The usage of PHP_FPM_ENV_VARS is not clear and setting this variable does not have any effect unless PHP_FPM_CLEAR_ENV=no also set. using image 7.3-4.14.5

$PHP_FPM_CLEAR_ENV is https://www.php.net/manual/en/install.fpm.configuration.php#clear-env. So when you have it to yes the env var $PHP_FPM_ENV_VARS allows you to selectively pass env vars you need in fpm

@csandanov $PHP_FPM_ENV_VARS usage is not clear, how to disable $_ENV[db_user] , etc to be passed?
How to add PHP_FPM_ENV_VARS as an array in docker-compose or .env?
This part is not clear.
Thanks

just pass env vars name you want to see in fpm as a json array: ["DB_USER", "DB_NAME"]
