Lately I wondered why my websites as well as the backend for my app (also available for Android) were so slow that the app was hardly usable. By wondering, I mean, I did’t get it, what’s happened in the underlying service, Openshift Online Starter v3. Actually I knew the cause, which was made by myself though. 😀
I was experimenting with SSL setup in the routes settings of Openshift project configuration page. There are 3 options for the secure route, Edge Termination, Passthrough Termination, Re-encrypt Termination, which are described on the official documentation page here. I have played with all those options, and the results were very very slow download speed, or maybe just the TTL. I had secure route to be activated for one of my subdomain need SSL, which was then to be paired with Full SSL option in CloudFlare. Yeah, I make use of it for the DNS server anyway. And as for SSL certificates for the Openshift route, I obtained it from Cloudflare’s. So, it’s obvious that there was a communication issue between them, particularly at SSL handshake session. Although, according to a comment for my question on Stackoverflow, he said that it’s a known issue on Openshift itself.
So, rather than disabling SSL for the sake of website speed, I was planning to move the data to traditional hosting, or VPS. I tended to choose the latter, as I have enough credit in Digitalocean right now. But, as I quite lazy to setup production server on a bare VPS, and my project was customized for Openshift, I’d rather searching for how to setup Openshift Origin on DigitalOcean. In the first run, I set up a Fedora Atomic droplet, that actually I didn’t understand what it was. 😀 Thanks to buddies on @FedoraID telegram group, I quite enlightened about it now. 🙂
Eventually, I found a thorough tutorial how to setup Openshift Origin on VPS. So, here I just want to share some screenshots of my success on setting it up. 🙂 FYI, it only took 2 hours for me to play around with it on Digitalocean droplet, as I realized that a 512 MB droplet would not sufficient to run Openshift service in it, as it encountered sudden stop so often due to the lack of memory.
