Welcome to day 6/40 of the Certified Kubernetes Administrator (CKA) course 2024! Now that we have looked into the fundamentals of docker and Kubernetes, it's time to get the Kubernetes cluster ready and start with the hands-on. We will set up a multi-node Kubernetes cluster using Kind on our local machine.
You might wonder why we are not using a cloud provider like GKE, AKS, or EKS. Using a cloud service would mean the cloud provider manages the control plane, limiting learning. If we want to learn Kubernetes from scratch, we must set up everything on our own. Once we do enough hands-on troubleshooting, we can move to a managed Kubernetes service later.
In this video, you'll learn:
- What are the options we have to host a Kubernetes Cluster
- Kind Tutorial to setup a single node Kubernetes cluster
- Kind tutorial on setting up a multinode Kubernetes cluster
- Set the context to switch between multiple clusters
- Kubernetes documentation
🚀 Reinforce your knowledge with practical tasks in the Day 6 folder of our GitHub repository: github.com/piy...
👨🏼‍💻 #40daysofKubernetes Challenge:
Join our 40-day challenge and solidify your Kubernetes skills. Details can be found in the "#40daysofkubernetes.md" file on GitHub or by watching our Day 0 video.
📖 Course Schedule:
I'll release 3-4 videos per week and host live Q&A sessions on weekends to answer your questions and guide you through the CKA certification process.
🕵🏻‍♂️ Who Should Watch:
This CKA course is designed for beginners, college students, and working professionals who want to learn Kubernetes from scratch, prepare for the CKA certification exam, or enhance their knowledge. It was designed based on the latest curriculum for the CKA exam in May 2024 and uses 1.30.2 as the Kubernetes version.
Let's start your Kubernetes journey together!

In my experience first time I'm listening that controlplane also need high availability , we can deploy multi controlplane. Thank you bro.

@TechTutorialswithPiyush 8 күн бұрын

Hello Anil, Yes control plane is also running on VMs and it needs HA. When you are using a managed cloud service and regional cluster , they already take of this by deploying your control plane nodes in 3 availability zones for HA.

I have used minikube before and it gives only 1 node. Good to know about kind, looks better than minikube

@TechTutorialswithPiyush Ай бұрын

Yes, its 10X better than Minikube and its lightweight as it runs containers as your nodes.

Hi Piyush, I have 3 part question for you: 1. Does CKA exam uses kind to setup Cluster/Control-plane? 2. Could we have mapped the first node to the multi-node cluster we created later? 3. How can we get our nodes to scale automatically with the help of CPU/memory metric or if some other metric is also possible like RPS/RT, this seems possible with autoscaling in AWS?

@TechTutorialswithPiyush 13 күн бұрын

Hello Sanyam, 1) They will have a remote desktop machine based on Ubuntu and they will provide you around 6 clusters in which you will be performing tasks. As there will be tasks around cluster upgrade, which is not possible with Kind, I dont think, they are using Kind. That is the reason we will be using multiple Virtual machines based cluster using kubeadm from video 27 onwards which is similar to the exam setup. You can check the below as well docs.linuxfoundation.org/tc-docs/certification/lf-handbook2/exam-user-interface/examui-performance-based-exams 2) We actually created 2 clusters, 1st cluster only had 1 node which serves as a control plane + worker node and other cluster has 3 nodes 1 master and 2 worker nodes 3) Yes, to scale out and add more nodes you use cluster autoscaling which is a feature provided by managed cloud services such as eks, aks , gke etc

"Great video! I'm learning a lot." I have a doubt about the installation of Kubernetes, How to decide which type of Kubernetes has to install means by a specification of Hardware or instance type or anything else?

@TechTutorialswithPiyush Ай бұрын

Thank you for the feedback. It depends on various factors such as cost, purpose , high availability and performance requirements, the level of control you want and so on. I have discussed that in detail in one of the later videos, stay tuned. For now, we have installed Kind which is ideal for learning, POC and a quick setup of kubernetes locally, this is better than minikube as it is lightweight , doesnt require much resources and supports multi-node setup.

Can we use Kind in the production ready cluster? How it is better then kubeadm, and how we can install using terraform or any other automated tools?

@TechTutorialswithPiyush 25 күн бұрын

KinD is for local testing and learning purpose not for production. Later in this series, we will setting up cluster using kubeadm

If we install minikube instead of kind, do the commands and processes stay the same or there is some significant change while using them??

@TechTutorialswithPiyush Ай бұрын

The commands are kubectl and its same for any kubernetes cluster however, minikube doesnt support multi node cluster , you will get only a single node also it is heavier than KinD. That is why I'd highly recommend KinD

i tried setting up in my vmware with a rhel8 vm it works fine and fails after that starting control plane section This is the error , failed to create cluster : failed to init node with kubeadm How to fix?

@TechTutorialswithPiyush Ай бұрын

That is why I did not start with kubeadm installation. I started with KIND so that every beginner can spin up the cluster in the beginning and once we have covered enough concepts, we can spin up the kubeadm cluster which is there in day27 video. I am assuming my audience are beginner to Kubernetes and if they face any installation/setup issue , they wont be able to fix that in the beginning, as we have not covered a lot of concepts now. We need to understand logging, different kubectl commands, static pods, TLS/SSL and other important concepts before that. I'd suggest setting up kind cluster now and you can follow along with kubeadm in day27 and let me know if you still face any issue.

"This error is likely caused by: - The kubelet is not running - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)" Please let me know how to resolve this.
