déployer

Deployer is a PHP-based deployment tool that automates the process of releasing web applications. It allows developers to manage deployments to multiple servers, ensuring consistency and reducing manual errors. The tool utilizes SSH to connect to remote servers and executes a series of tasks defined in a deployment script. This script can include steps such as updating code, migrating databases, clearing caches, and restarting services.

One of Deployer's key features is its task-based architecture. Users define tasks in a `deploy.php` file, which can be chained together to create complex deployment workflows. Deployer supports various deployment strategies, including rolling deployments, which update servers one by one to maintain application availability, and blue-green deployments, which switch traffic between two identical production environments.

Deployer is highly configurable and extensible. It provides a set of built-in tasks for common deployment operations, and users can create custom tasks to suit their specific needs. The tool also integrates with popular PHP frameworks like Symfony and Laravel, offering pre-defined tasks tailored for these frameworks. Its focus on simplicity and efficiency has made it a popular choice for developers seeking a reliable and automated deployment solution.
