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. What You Need: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 Windows machine.
