I built a Kubernetes cluster at home. It's running on a couple of Raspberry Pi's.
The reason for doing that was again to get hands on practice, but also because I wanted to have
a free place to run any hobby app that I wanted.
Often I want to have something running somewhere. I would pay about 10$ a month choosing to run it on Heroku
But I just got a headache thinking about whether I would keep paying for it each month or not
I just didn't want to have to think about it anymore.
I've started writing an article about setting up the cluster.
It's not finished, but if you're interested you can find the article
