Jekyll on Heroku

Summary

Jekyll can be deployed on Heroku to use its plugin system, but relying on jekyll serve would use Ruby’s single-threaded WEBrick rather than a production-oriented web server. The setup installs Ruby with ruby-install and chruby, then installs Bundler and Jekyll, creates a site, and tracks it in Git. Heroku’s official Ruby buildpack handles dependencies and runs a Rake assets:precompile task that executes jekyll build, while the Static buildpack serves the generated _site/ directory according to static.json. The example pins Ruby 2.4.2, adds Rake, enables clean URLs and HTTPS, and completes with a successful deployment of the generated site to a Heroku URL.

Takeaways

1. 1

   static.json sets clean_urls and https_only to true and uses _site/ as the serving root.

2. 2

   The Rakefile defines assets:precompile to execute jekyll build, allowing Heroku’s Ruby buildpack to generate the complete static site during deployment.

3. 3

   The example pins Ruby to 2.4.2, adds Rake to the Gemfile, and finishes with a successful Heroku deployment using both buildpacks.
