Day 34/40 - Step-By-Step Guide To Upgrade a Multi Node Kubernetes Cluster With Kubeadm

Step-By-Step Guide To Upgrade a Multi Node Kubernetes Cluster With Kubeadm
Welcome to Day 34/40 of Certified Kubernetes Administrator (CKA) series 2024! In this video, we will understand everything about Kubernetes releases and how to upgrade a multi-node Kubernetes cluster from one version to another using Kubeadm.

👨🏼‍💻 #40daysofKubernetes Challenge:

📖 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!

Thanks Piyush you made this so easy but explaining the steps even more detailed and real with error and issue then paid course . cheers :)

[MegaRagtag]

Great work man, this video is very helpful and also in detail. am going to upgrade soon.

[rajeshtalla]

Very well Explained. Everything needed is in detail. Great!😃

[rajeshvi]

Piyush you are amazing, i have recently joined your community, thank you again for sharing knowledge with everyone.

[abc-edm]

your video makes it more enjoyable on learning K8s, thanks Piyush!!!!

[narsinghsaini]

Very Easy to Understand. Thanks for the amazing content.

[codinggeeg]

amazing content! following it from day 1 and it's really amazing

[vikashswain]

on youtube I have watch many videos related to k8s but none of them explained related to upgrades. thanks for this amazing content.

[SinghBalraj]

Great demonstration! How to upgrade the cluster. I had seen a couple of videos, but no one explained in detail like you. You are amazing and explain each task in detail, which is easy for a beginner like me to understand.

God bless 🙌
keep up the great work.👍

[nareshv]

Thanks for dedicating your valuable time....very informative and helpful

[jhonsen]

No one Explained this Drain and Cordon conecpt . Exellent.

[hamzaerrahma]

Thank you for this video. For example, when working with a cluster where we don’t know if there are static pods (like MySQL in your case), and we want to drain a node, won’t we lose the static pods?

[pankajtoconnect]

Thanks for your great efforts, could you please make a video on eks upgrade using terraform or eksctl without downtime

[ajitsahoo]

Hi Piyush, another question for this point.

Lets we so have couple of pod running a Node and we are using Nodeaffinity for scheduling the pod. So that those Pods can run on specific node only.

If we go for a upgrade of a worker node and those pods are drained out of the nodes then there will be be massive outage for the application that running on those pods. Right?

How to come up this issue?

[vikashswain]

great explanations!. do we have to use same procedure for EKS upgradations .

[ajitsahoo]

What will happen if you upgrade the master node?

Means we are running multinode cluster not a HA clustering

In that scenario our application will be down for certain time?

[baivabmukhopadhyay]

Please also make a video doing installation of kubeadm and updating it in azure vms

[suhasiniaddanki]

If a node is assigned as daemonset, cant do we Cardon that node?

[IqbalShaikh-kj]

Need video regrading Upgrade Kubernetes Cluster with Kubeadm from 131.1 to 131.2

[pankajtoconnect]

Thanks for making this video. Sir could you make a video on eks upgrade using terraform or eksctl . Today I given a interview they have asked this question, also in this video you have discussed to upgrade automation could you please suggest, how we can do that, because if I have 100 worker node then each will take more time.
