Last time we showed you how to deploy Phoenix application to Heroku. In this article we will show you how to host static website there.

Recently we wanted to setup a staging environment for one of our Jekyll powered websites on Heroku.

It turns out, it’s easy to host Jekyll websites as rack apps with the puma server - so we thought we’d share with you how to do it.


Update Gemfile

You need to add the following gems to your Gemfile:

  • rack-jekyll - for transforming your Jekyll app into a rack app
  • rake - for generating pages during deploy (necessary because Heroku provides a read-only filesystem)
  • puma - for serving your rack app

Create Procfile

Heroku uses Procfile for declaring what commands are run on dynos, so we need one as well:

web: bundle exec puma -t 8:32 -w 3 -p $PORT

This basically will start puma with 3 workers and 8-32 threads per worker. You can find all the config options here.


Since we are going to run a rack app we need file:

require 'rack/jekyll' require 'yaml'


Now are ready to deploy our app to Heroku:

git push heroku master
