From Rails 7.1 onwards, Kamal 2 is included as a first-class tool for container-based deployments. Kamal aims to make shipping Rails apps to production as painless as possible using Docker.

Unfortunately, I couldn’t find any good documentation on how to do this, even though it turns out to be quite straightforward.
