Deploying modern web apps – with all the provisions needed to be fast and secure while easily updateable – has become so hard that many developers don’t dare do it without a PaaS (platform-as-a-service). But that’s ridiculous. Nobody should have to pay orders of magnitude more for basic computing just to make deployment friendly and usable. That’s a job for open source, and Rails 8 is ready to solve it. So it’s with great pleasure that we are now ready with the final version of Rails 8.0, after a successful beta release and several release candidates!

Rails 8 comes preconfigured with Kamal 2 for deploying your application anywhere. Whether to a cloud VM or your own hardware. Kamal takes a fresh Linux box and turns it into an application or accessory server with just a single “kamal setup” command. All it needs is the IP addresses for a set of servers with your SSH key deposited, and you’ll be ready to go into production in under two minutes.

Kamal can do this so easily because Rails already comes with a highly efficient and tuned Dockerfile for turning your application into a production-ready container image out of the box. All you need to bring is your own container registry account, like Docker Hub or GitHub, for storing the images.
