Building Ruby Head for Your Rails App

Discover how to stay ahead of Ruby version upgrades in this 34-minute conference talk from RailsConf 2023. Learn to build and run Ruby head, the latest commit to Ruby's main branch on Github, for your Rails application tests using Docker. Explore the process of creating a Docker image with Ruby head and integrating it into your Buildkite testing pipeline. Gain insights into the benefits of using jemalloc, an alternative malloc implementation, and understand the importance of this work for both your team and the broader Ruby community. While running production code on Ruby head may be risky, this talk demonstrates how to leverage it for testing, keeping your Rails app at the cutting edge of Ruby development.
