Deploy an EKS Cluster Based on Fargate Compute Only

kubernetes

bloomvideo

The aim of this tutorial is to deploy a functional self-managed Kubernetes cluster on AWS using EC2, setup an Ingress controller(HA-Proxy) and run a sample app that will be accessed via public internet on your browser. The infrastructure deployment is automated using Terraform and the cluster deployment done using Kubespray. Nginx web server will be used as the LoadBalancer running on EC2. You will learn how to setup a BareMetal cluster securely on AWS and how to limit access to the environment. The tutorial will give you more of a starting place on which you can build to create a production ready cluster while observing the best security practices. We will walk through all the steps from setup to running the demo application and accessing it on the browser. During my learning journey as a Kubernetes Administrator, I found it hard to get a full tutorial that explained this steps fully, that is why I am sharing this to help any learner out there who may be on the Kubernetes learning journey. You can find shared snippets of the parts of this tutorial that had longer code portions here: <a target="_blank" rel="noreferrer noopener" href="https://gist.github.com/briancollins081/e43e1bf9213a78c7b869443eb0450205" alt="https://gist.github.com/briancollins081/e43e1bf9213a78c7b869443eb0450205" class="on">https://gist.github.com/briancollins081/e43e1bf9213a78c7b869443eb0450205</a>​ <div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe src="https://www.youtube.com/embed/XVp79PIiGMo?&amp;t=0s" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" data-file-name="XVp79PIiGMo?&amp;t=0s" data-file-size="0" data-origin="100%,56.25%" name="XVp79PIiGMo?&amp;t=0s" style="width: 100%; height: 100%;" data-index="0"></iframe></figure></div> Tutorial chapters:<ol><li>​<a target="_blank" rel="noreferrer noopener" href="https://www.youtube.com/watch?v=XVp79PIiGMo&amp;t=0s" alt="​0:00 Introduction, requirements and the roadmap.">​0:00 Introduction, requirements and the roadmap.</a>​</li><li>​<a target="_blank" rel="noreferrer noopener" href="https://www.youtube.com/watch?v=XVp79PIiGMo&amp;t=154s" alt="​2:34 Preparing AWS account user and policies.">​2:34 Preparing AWS account user and policies.</a>​</li><li>​<a rel="nofollow" href="https://www.youtube.com/watch?v=XVp79PIiGMo&amp;t=500s" alt="8:20 DNS Configuration -
