Shipping Rails on Docker

Deploying Ruby on Rails Applications with Amazon EC2 Container Service

About the Book


This book has been republished. Please visit for more information.

If you still haven't figured out how to successfully deploy a Rails Application using Docker, then this book is for you. While there are several available technologies you can use, I'll show you why Amazon EC2 Container Service is the strongest contender. You'll learn some of the best practices that I've found while deploying applications with this new tool. Using the powerful Amazon Command line interface, I'll teach you to launch a complex application with a very realistic architecture and also how to create a complete Continuous Integration environment using Jenkins.
