Follow along as our friends at Phusion walk us through the process of creating a GitHub Actions workflow to build and publish a Ruby gem to the RubyGems registry.

One of the actions featured in the version that’s currently exclusively available to GitHub employees and a selected and undisclosed group of Beta testers, is the ‘GitHub Action for npm’, which wraps the npm CLI to enable common npm commands.

We set out to instead make an example workflow to build and publish a Ruby library (or: gem) to the default public registry, and created a GitHub repository, with a Docker container for a ‘Rubygems’ action: github.com/scarhand/actions-ruby
