You should start with the Kubernetes docs and then read the tutorials. Start with the tutorial but you should really read all the documentation. Its actually not too long a read.

1) https://kubernetes.io/docs/concepts/overview/components/ 2) https://kubernetes.io/docs/tutorials/kubernetes-basics/ 3) https://kubernetes.io/docs/tasks/run-application/

After reading these documents and doing the tutorials, its a matter of gaining experience.
