Docker for Rails Developers
Build, Ship, and Run Your Applications Everywhere
by Rob Isenberg
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
lengthy setup tasks, replaced instead by a simple, consistent,
Docker-based development environment that will have your team up and
running in seconds. Gain hands-on, real-world experience with a tool
that’s rapidly becoming fundamental to software development. Go from
zero all the way to production as Docker transforms the massive leap of
deploying your app in the cloud into a baby step.
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.
All you need is a Windows, Mac OS X or Linux machine to do development
on. This book guides you through the process of installing Docker. Some
basic familiarity with Linux/Unix is recommended even if you’re using a
