I've been looking at moving our system to Kubernetes, as it seems mostly cloud agnostic and should work well for our use cases. However, I was put off by the somewhat ad-hoc set of installation methods which mostly seemed to boil down to "Run a big opaque script that does a thing to specifically work with your provider".
Really glad to see a dead simple setup - I'm not exactly unfamiliar with operations or containers or Linux or anything, but a turnkey setup so I can play on my DO effortlessly to get an idea is really nice! And I only started looking recently, so having `kubeadm` available now is quite convenient.
If you want a completely non-opaque way (or just see the steps in general) of installing Kubernetes, check out Kubernetes The Hard Way [1].
That said, `kubeadm` is a great addition!
