php-fpm and Nginx dynamic environment variable

Question

FPM configration stats that you can retrieve variables from your current environment. However, on ubuntu using Nginx and PHP-FPM, I can not find a way to retrieve the variable value from the environment without hard coding it in the php-fpm.conf or nginx fcgi params.

Is there a way to get the environment variable from /etc/environment or /etc/bash.bashrc?

For ex:

clear_env = no ENV[SECRET_TOKEN] = $SECRET_TOKEN 

I think the main problem is not being able to modify the env vars for www-data. As >sudo -H -u www-data bash -c "env" does not include SECRET_TOKEN.

Answer 1

Looks like the only way is to add the env vars manually.

I modified the code a bit

#!/usr/bin/php <?php $confFile = '/etc/nginx/fastcgi_params'; // Update the fpm configuration to make the environment variables available // NOTE: ONLY in the CLI will $_SERVER have environment variables in it. $content = file_get_contents($confFile); $line = false; foreach ($_SERVER as $name => $val) { if (strstr($name, 'SYMFONY') !== false) { $line = "fastcgi_param {$name} {$val};\n"; # Either Add or Reset the variable if (strstr($content, $name) !== false) { $content = preg_replace('/fastcgi_param[\s\t]+'.$name.'\][\s\t]+.*?\n/', $line, $content); echo "MODIFIED {$name}\n"; } else { $content .= "\n{$line}"; echo "ADDED {$name}\n"; } } } if ($line) { file_put_contents($confFile, $content); }
