What is Capistrano?

[SOUND] In previous workshops we manually deployed 0:00 our Rails app to a production environment. 0:04 We cloned Git repo with our Rails app to a server, created the database, 0:09 set up configuration for Nginx in Unicorn, and more. 0:13 For every additional server we set up, we're going to need to repeat those steps. 0:16 And every time we release a new app version, 0:20 we'll need to pull changes from Git and restart our server. 0:22 If we do all this manually, over time the potential for mistakes adds up. 0:26 So, in this course, we're going to show you how to do all this automatically 0:30 using the Rails community's most popular deployment framework, Capistrano. 0:33 Capistrano can make your deployments fast, easy, and safe. 0:37 This guide covers Capistrano 3 which was released in 2013. 0:41 It has several incompatibilities with Capistrano 2 and earlier. 0:45 So, when you're searching the web for troubleshooting tips you should double 0:49 check any source written before 2013, as the info may be outdated. 0:53 Also, be aware that Capistrano scripts often have to be highly customized for 0:56 the environment they're deploying to. 1:00 We're deploying to a completely fresh Ubuntu server using RPM, PostgreSQL, 1:02 and Nginx. 1:07 If you are set up different from this in any way, you're almost certainly 1:09 going to have to make some changes to the Capistrano code shown here. 1:12 Be sure to check the teacher's notes for troubleshooting help and 1:15 try pasting any error messages you get into a search engine. 1:18 Today, we'll be giving you an introduction to Capistrano. 1:21 But in the end, 1:24 you'll have a little bit of work to do in order to get it going with your setup. 1:24 Okay, ready? 1:28 Let's take Capistrano for a spin. 1:29
