This document discusses zero downtime deployments using Laravel Envoy. It begins with fundamentals of deployment including definitions, best practices, and tools. Common deployment tools mentioned include Capistrano, Ansible, and Envoy. The document then introduces Laravel Envoy, describing it as a tool to define common tasks on remote servers using Blade syntax. Key points about Envoy include installing it globally, writing tasks in an Envoy.blade.php file, and running tasks via the envoy command. The document concludes with an overview of how Envoy enables zero downtime deployments through stories for setup, deploy, and rollback.

❖Reference: https://github.com/FramgiaCD/envoy-config
❖Three main stories:
➢ Setup
➢ Deploy
➢ Rollback
envoy run deploy --on=local,staging --branch=develop
// OR
envoy run deploy --on=production --branch=master
envoy run rollback
// OR
envoy run rollback --rollback_version=20160923022158
