Jekyll site on Heroku with 6 workers ready to take on your massive traffic without first having to generate the Jekyll site locally and there's no need for a third-party buildpack. And the best of all, it runs on a single and free Heroku Dyno.
I have previously used
jekyll --serverin my
Procfile on Heroku which in turn generated the jekyll site and booted up a webrick server. But I wanted to run my site with Unicorn and it's support for multiple workers on a single Dyno. And to do so my Jekyll site must be a Rack app.
Rack-Jekyll to the rescue! It was exactly what I was looking for, it turned a Jekyll site into a Rack app. I had some issues with it on Heroku and made a pull request with the fixes. At this moment it has been merge with the master but there is not a new version released of the gem.
Jekyll-Heroku-Unicorn is a sample app of a simple Jykyll site with 6 Unicorn workers ready to be deployed to a free Heroku Dyno:
git clone firstname.lastname@example.org:himynameisjonas/jekyll-heroku-unicorn.git
cd jekyll-heroku-unicornand run
heroku createfollowed of
git push heroku master
heroku openand you're done!
