But maybe, like in any social network, there is a bias on what is put in front page. And if you have an interesting project, you might want to add an extra layer of complexity and use Kubernetes in order to gain more visibility.

Well, making things intentionally difficult sounds really stupid, but you learn a whole lot in the process, and for a side project geared towards gaining knowledge, this seemed perfect :) And in the process of setting this up I figured a new way to debug my deployments for remote k8s clusters, using kilo. Also sidenote, yes I actually do host a couple other things on my cluster including my blog, so I didn't really want to spin up a new instance just for DNS and VPN

It's also a example of a project where you can learn more about a platform. Yes, it could be run outside of k8s, but perhaps the author wanted to add the extra layer of "difficulty".
