Setup Coreos Cluster Manually with Virtualbox
Recently, I wanted to set up a tiny CoreOS cluster in my laptop, the good news is that with several commands and the existed Vagrantfile offered by the CoreOS official guide, we can setup a cluster in minutes; the bad news is that I don’t like everything perfectly done by Vagrant like a magic box, I want to do it total manually, and there’s no tutorial as I expected.
So as I made it work finally, it’s time to share with others.
