This is an amazing set of Kubernetes learning materials and tutorials from Microsoft, published in 2018. It’s full of videos and a minor amount of reading. You can probably blow through this in two or 3 days with a serious amount of dedication. If you just want to be relaxed about it, it would probably take you about a week and a half. It’s super simple to understand, and is designed for people with, as the title suggests, almost no knowledge of Kubernetes.
