Jekyll to Harp

Harp Web Server In late 2014 whilst working on AngularJS frontend apps on Herkou, I discovered and recommended Harp web server to the team. Harp is a powerful static file web server with built-in template proprocessing. It helped us eliminate much tedious build tasks and ruby gems from our static client projects. If you haven’t heard of Harp, have a read of Sintaxi’s Introducing Harp.

Half a year later, I have also decided to migrate over to harp for my personal blog. For smooth transitioning of my articles and meta data from Jekyll, I used the awesome Jekyll2Harp. My blogs now consists of just my articles and HTML/CSS templates, and Harp preprocesses all my static files on the fly. No more Jekyll gems, no more compile commands. Also I no longer need to prefix my blog posts with the timestamp which is really neat. Lastly my Disqus comments was moved using Disqus Migration Tools.

For a new blog template I picked Kenneth Ormandy’s HB-Simurai. It has an slight oriental feel and fits will with my personal seal.

The next question is where to host my harp blog. There are several options:

  • Use static harp compile to deploy to GitHub Pages. But that kinda beats the point of drop in preprocessing.
  • I tried for a while, it’s very easy to use but and I highly recommend it.

However as a Software Engineer I’m not a fan of using Dropbox as source control and wanted to be more hands on. In the end I settled on the following DIY solution:

  • Architecture My blogs are effectively Harp Microservices within Docker containers. I created my own minimal AlphineLinux Harp containers.
  • Build: GitHub commits triggers, which is Continuous Delivery for Docker. See my build status: Docker Repository on
  • Deploy Successful Docker builds kicks off deployment webhook in Tutum Cloud. Tutum takes care of Container orchestration and load balancing.
  • Virtual Machines provided by Windows Azure.
  • DNS and CDN using the free and powerful Cloudfare.

It’s a bit of a overkill but it was quite a fun process and a good refresher on the similar setup I built at work a few months back. I will write a more detailed blog in the future in regards to the Tutum Cloud and Docker container setup.
