Learn Kubernetes 
🔨🔧
This guide is aimed to fast-track your Kubernetes learning by focusing on a practical hands-on overview guide.
This means, not too much of a deepdive, but enough to get a feel for the required building blocks of Kubernetes so you can align it with a real world problem that you are trying to solve.
The problem: "I want to adopt Kubernetes"
The problem: "I have some common existing infrastructure"
Our focus: Solving the problem by learning each building block in order to port our infrastructure to Kubernetes.
