Deploying Jekyll website to Heroku

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:

1 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:

1 2 require 'rack/jekyll' require 'yaml' run


Now are ready to deploy our app to Heroku:

1 git push heroku master
