On this day in 1976, the Apple I was released, having been designed and hand-built by Steve Wozniak himself. As of 2018, only six units remain in working condition.

Platforms come and go, libraries change out from underneath you, and consistency can be hard to wrangle. You need something that makes system setup a breeze: Docker does for DevOps what Rails did for web development—it gives you a new set of superpowers. Gone are "works on my machine" woes and twisty little setup tasks.

Docker for Rails Developers: Build, Ship, and Run Your Applications Everywhere shows you how, now in beta from pragprog.com/book/ridocker.

Come. And. Get. It.

Docker for Rails Developers: Build, Ship, and Run Your Applications Everywhere

Docker makes life as a Ruby and Rails developer easier. It helps build, ship, and run your applications, solving major problems you face every day. It allows you to run applications at scale, adding new resources as needed. Docker provides a reliable, consistent environment that's guaranteed to work the same everywhere.

Docker lets you do all things DevOps without needing a PhD in infrastructure and operations. Want to spin up a cluster to run your app? No problem. Scale it up or down at will? You bet. Start by running a Ruby script without having Ruby installed on the local machine. Then Dockerize a Rails application and run it using containers, including creating your own custom Docker images tailored for running Rails apps. Describe your app declaratively using Docker Compose, specifying the software dependencies along with everything needed to run the application. Then set up continuous integration, as well as your deployment pipeline and infrastructure. Along the way, find out the best practices for using Docker in development and production environments.

This book gives you a solid foundation on using Docker and fitting it into your development workflow and deployment process.

Now in beta from pragprog.com/book/ridocker.
