Deploy a Rails app to a VPS with Kamal

Ruby on Rails has always been at the forefront of developer productivity, and building robust, highly interactive web applications has never been easier. Rails has been accurately described as the one-person framework. However, building your app is only half the battle. The other half is publishing it for others to use. Unfortunately, being able to deploy your application has always been an afterthought for most developers. The "one-person framework" doesn't carry through when it comes to deployment and operations unless you have specialized knowledge of building out infrastructure or pay others large sums of money to do it for you—until now. With the release of Kamal, the "one-person framework" idea completes the stack from end to end, allowing a single developer to do more with fewer resources.
