Rails on Docker · Fly

Rails 7.1 is getting an official Dockerfile, which should make it easier to deploy Rails applications to production environments that support Docker. Think of it as a pre-configured Linux box that will work for most Rails applications.That means you'll start seeing a Dockerfile in the project directory of a lot more Rails apps. If you're not familiar with Docker, you might open the file and see a few things that look familiar like some bash commands, but some other things might be new and foreign to you.
