Have you ever botched a deployment and taken a site offline? I have - more times then I'd like to admit. What if we could completely automate the deployment process, make it lightning fast, remove most of the risk, and do it all without custom bash scripts? Better yet, what if we could use the same exact deployment process locally or trigger it via CI? All of this is possible with Deployer - a PHP-based deployment tool which supports virtually every CMS and framework! Attendees will learn the basics of Deployer, how to customize deployments to fit their needs, and how to handle situations if things go wrong.
