This is the third and final post in my “Kubernetes on your Laptop” series. In this post, I will show you how to install Kubernetes on Ubuntu server. If you haven’t read the previous posts, I recommend you go back and ensure you have an Ubuntu server running on your laptop before proceeding.

This is the second post in my “Kubernetes on your Laptop” series. In this post, I’ll show you how to install Ubuntu Server on a virtual machine using VMware Fusion. If you need help installing VMware Fusion, check out my previous post.
First thing we need to do is download the Ubuntu Server image based on your machine’s architecture:

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.

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:
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.

Start by creating a new repository on GitHub or cloning an existing one. Then make sure you have a Dockerfile in the root of your repository.

To begin, you will need to have the following:
We will also be using the following tools:
Continue readingIn my previous posts, we learned how to get started with GitOps on AKS using the K8s extension for AKS.
Then, we took a look at the Flux CLI and explored how it can be used to bootstrap your cluster and generate FluxCD manifests so that we can use GitOps to implement GitOps 🤯, and implemented Flux’s image update automation capability.
From there, we built on the concept of image update automation, and showed you how you can use Flagger to automate canary deployments.
