Kcna

Hello there. In the previous article we reviewed Kubernetes and its resources and we talked about how to manage a resource. That was a basic introduction to Kubernetes. In this article we will dive deeper into Kubernetes and start discussing its architecture.

From the image I shared above, Kubernetes has cluster components that handle container orchestration. These are the control plane and the worker nodes. Let’s focus on the control plane and the worker nodes and review how they work.

Two weeks ago there was a discount on Linux Foundation exams, so I bought the KCNA (Kubernetes and Cloud Native Associate) exam because it looked like a good starting point. I wanted a short, focused review about 30 pages of notes to study before the exam, but I could not find a reliable one, so I made my own.

I will publish a series of posts about KCNA (and later CKA) as a short study guide. In this first post I explain what the KCNA exam covers, how it works, and how to prepare. Later posts will cover each topic with short explanations and key points. I will use simple language and keep the content short and practical.
