The Canfranc International railway station is a massive station in the Spanish Pyrenees. At the time it was built, it was the second largest railway station in Europe, but it's in the mountains, far away from any major city. It's a large station because it was the connection point between the French and Spanish railway systems. The systems had different rail gauges, so all passengers, luggage, and freight had to be transferred from one train line to the other, in addition to dealing with customs and international inspections. Although it no longer operates today, at the time, the huge, opulent station was called "The Titanic of the Mountains."
If you're a Rails developer, you're facing a gauge mismatch between the Rails systems you've been running for years and current Docker environments. Let Docker for Rails Developers be your Canfranc International station, and learn how to build new Rails applications with Docker as well as adapt existing ones.
Don't wait for the train; get started right now.
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.
Get started using Docker and fitting it into your development workflow and deployment process.
