Automated Deployment with Capistrano
•
1 like•10,044 views
Are you still using FTP to deploy your code? Are you still manually performing the same steps of deploying a feature, again and again? How many hours have you spent on ssh-ing into the server, pulling the repo, migrating the database, reloading the web server and so on, for each deployment?? Ever wondered if there is a process as simple as a single click to perform all these steps for you? Automated Deployment does exactly these things for you. It takes the burden of remembering all the steps required in each deployment process and execute it smoothly.
