A lot of us are really busy and while it is nice to read the “create your own Kubernetes” posts, sometimes you just don’t have time to do so. If you just want to jump in and learn to swim as @Rick Vanover said in the last Weekly recap 20 https://www.youtube.com/watch?v=0wn7m1F3lvI then there are some ready to go free clusters that you can play around with. My favorite is the O’reilly Katacoda kubernetes playgroud https://www.katacoda.com/courses/kubernetes/playground but many big cloud providers will give you some free time to evaluate as well. 

A nice full list has also been composed by a github user name salaboy and learnk8s with various contributors here https://github.com/learnk8s/free-kubernetes

Kubernetes is very much a hands on technology. The more you practice the easier it gets. 

Good luck and most importantly have fun!!
