Docker & Container Runtimes, News & Announcements

A 10-minute guide to Kubernetes

Editor: This article was originally published by Omer Dawelbeit under the title “Learn the Kubernetes Key Concepts in 10 Minutes”.

In this post I will provide a brief explanation of the key concepts of Kubernetes. I will avoid using lengthy definitions, these are already available in the Kubernetes documentations.

Rather, I will be using a few diagrams (some animated) and examples to explain these concepts. I found a few of the concepts difficult to fully grasp without a diagram (Service for example). Where appropriate, I will also provide links to the Kubernetes documentations if you want to deep dive.
