How should secrets be handled for Runner scaling?

Handling secrets in a scaled runner architecture is critical for maintaining security and operational integrity. When deploying runners across multiple instances, it's essential to ensure that sensitive information like API tokens, database credentials, and configuration secrets are not hard-coded or exposed in the deployment process. Below is an example of a recommended approach for managing secrets securely in such environments.

<?php // Load environment variables from a .env file require 'vendor/autoload.php'; $dotenv = Dotenv\Dotenv::createImmutable(__DIR__); $dotenv->load(); // Example of using secrets safely $dbUsername = $_ENV['DB_USERNAME']; $dbPassword = $_ENV['DB_PASSWORD']; try { $db = new PDO('mysql:host=localhost;dbname=mydb', $dbUsername, $dbPassword); // Perform database operations } catch (PDOException $e) { echo 'Connection failed: ' . $e->getMessage(); } ?>
