Relocating from OpenShift v2

Posted on May 18, 2018

This post summaries my efforts over September and October to migrate my websites and apps away from OpenShift v2 to other hosting platforms as Red Hat finally closed it down.

What is OpenShift?

OpenShift is an PaaS service by Red Hat originated from 2011, it provides infrastructure for users to deploy their apps with little to no concern about the underlying infrastructure where the app runs on. Deployment can be as simple as a git push command, given that the git post-receive hooks have been properly configured.

I have been using OpenShift v2 since 2012 to deploy production application for my freelance and personal projects. The free bronze tier of OpenShift v2 allows for 3 ‘gears’, which are instances of a virtual machine on OpenShift platform. The resource constraint never bothered me. If you run out of 3 gears, you can register for another OpenShift account, then link the new account to the existing one such that you can use the same SSH public key to deploy to the 3 additional gears in the new account.

That means you can run virtually unlimited number of apps for free, without credit card.

To Red Hat, this exploit might have costed them so much that they had to close down OpenShift v2 in favor of the newer OpenShift v3. On OpenShift v3 the cheapest tier ‘Starter’ allows for only 1 project, the next tier ‘Pro’ allows for 10 projects at $50/month. Well, OpenShift v2 could have died of old age though.

That sucks. I had to move 14 websites/apps, including a client project from OpenShift to other platforms:

Options aside from OpenShift v2

I love free things. Free things that remain free in long term are even better. On September I had these options:

Digital Ocean offers virtual private server that I can install anything on. AWS, Azure and GCP provide a wide variety of products and solutions to suit various requirements and at different price ranges.

If you don’t mind open-sourcing your static site or that your site uses external APIs for dynamic features, GitHub Page would be your best choice because it’s completely free and ships with HTTPS by default.

Post-OpenShift v2 life of hosting

Long story short, I moved all static assets from OpenShift to GitHub Page. These include blog, static websites and web apps using self-hosted database like Hoodie. For sites that are dynamic, I would re-think whether it needs to be dynamic, or whether I really need the site itself. I will go into more details about those sites. And for those which I really must host on a VPS, I hosted them together on one single instance on Linode or Digital Ocean, whichever I have free credits on.

Static sites

GitHub Pages are great because it is free, it hosts reasonably big static sites, it serves sites over HTTPS, it allows for CNAME binding so I could use the domain names of my choosing and I have never had any issue with it except the deployment time after git push is rather random.

My sites and web apps locally using static site generator such as Nanoc or bundler such as webpack, then I would commit the build to gh-pages branch of my repo, then off it goes with git push.

I have deployed some of my progressive web apps and deployed them using the gh-pages package from the npm repository. It copies your build folder and commit it to the gh-pages branch, and deploy (push) it to GitHub. As my PWAs are using a self-hosted Hoodie backend of mine to store the data, I did not have to worry about leaking my keys or tokens to the public because my apps simply don’t rely on them.

Unnecessarily dynamic sites

After writing the post about doing things the layman way, I have embraced the lazy approach to things — I don’t have to do everything by myself, and if I am to do them myself, I would take the shortest path and the easiest approach.

Which means I discontinued my project of building my own bookmarking service link2 and embrace the simplicity of Google Form and Spreadsheet instead. Simple, easy, and free. I didn’t have to pay for my own bookmarking now, and Google probably won’t care enought to look at my Spreadsheet to try to “understand” me.

I used to host a website that tells you which room on campus is probably empty, so instead of going to the library where everyone is coughing or sneezing or both, people can use empty classroom to study free from distractions. The website was written in Laravel, which requires PHP and a MySQL database. Deeper look into the service made me realize that it doesn’t have to be dynamic. It could just be a bunch of JSON files, and a progressive web app that loads up those files for once, then read from cache forever. Yes, the service is no longer dynamic and it’s now hosted freely on GitHub Pages instead.

Dynamic sites, databases and bots

Although offloading static content to GitHub Pages saved me a bunch of money from VPS, some still require a server to run on. For example, a Hoodie backend requires a Node.js environment and CouchDB. Plus I am running a bunch of small Telegram utility bots and web services such as a link shortener, a wrapper for youtube-dl and HTTP file server as its companion, and some secret sites of mine.

I don’t need 512MB RAM and 1 vCPU per service. In face, an VPS instance of 1GB RAM and 1 vCPU is more than enough to run all of them. I used docker to better maintain multiple servers and services in containers, and fired up a Nginx reverse proxy to tunnel traffic for each service into their respective container. It’s automatic and I could disable/enable any of them with a few lines of commands.

I paid $5/month to Linode for an VPS instance which I run multiple services on. It is fairly cheap, but if I wish I could even set the same thing up at home, using a Raspberry Pi 1 Model B which I had no purpose for since I have bought it a few years back. I could set up port-forwarding from my router, and use ddclient to update my Cloudflare DNS record automatically. However, the marginal benefit of doing this would be minimal compared to having an VPS on the cloud where they have better spec and more bandwidth.


OpenShift v2 has been the birth place of my career by allowing me to host my random and mostly crappy creations over the years, but I had to move on. Like dynasty, hosting services live and die. They might discontinue all of a sudden for a lack of profit or prospect (obviously). And people have to move on. Hosting has never been as cheap and accessible as today, and I wish they continue to live on, free or paid alike so I could continue to have a place on the Internet.
