Study Guide: Kubernetes and Cloud Native Associate (KCNA)

My KCNA certification is up for renewal, and as I’m preparing to retake the exam, it dawned on me that I wrote up a study guide for it never actually published it. Doh! 🫣

So here it is 🤗

The KCNA is a great entry point for anyone looking to validate their foundational knowledge of Kubernetes and the cloud native ecosystem. I thought it would be helpful to document my study notes and share them with others who are also preparing for the exam.

Certified Argo Project Associate (CAPA) Exam Study Guide

I recently passed the Certified Argo Project Associate (CAPA) exam and wanted to share a study guide to help you prepare for the exam.

I’m preparing to renew my CKA and CKS certifications, and to practice, I’ve decided to set up a local Kubernetes cluster as a lab environment on my laptop to work with control plane components which isn’t be possible in a managed Kubernetes environment like GKE, EKS, or AKS. There are other local Kubernetes options like Minikube, Kind, Docker Desktop, or Rancher Desktop but you may run into some limitations especially as you try to prepare for the CKA and CKS exams. I wanted to have a full-blown Kubernetes cluster running locally without any restrictions.

Study Guide: Kubernetes Certified Security Associate (KCSA)

I’ve been studying for the Kubernetes Certified Security Associate (KCSA) exam, and I thought it would be helpful to document my study notes and share them with others who are also preparing for the exam.

Publishing Helm Charts to GitHub Container Registry

So you have a local Helm chart that you want to share with others?

In this quick tutorial, I’ll walk you through the process of publishing Helm charts to your very own Helm repository using GitHub Container Registry and GitHub Pages using GitHub Actions.

Before you begin, make sure you have the following prerequisites:

• A GitHub account
• A GitHub repository with your Helm chart
• GitHub CLI installed on your local machine
• Bash shell

GitHub Pages Setup

We will use GitHub Pages to host the Helm repository. So you will need to create a new branch called gh-pages. This branch will contain the Helm chart binaries and a README.md file with instructions on how to use the helm repo and install its charts.
