📌 The most obvious reason for a Kubernetes cluster upgrade is the software aging. We must upgrade the cluster on a regular basis to stay up with the newest security features
📌 Keeping up with new versions is a key element of your infrastructure security strategy since it allows apps to immediately benefit from new features.
📌 If there are multiple master nodes, in that case we need to update all the masters and worker nodes and their components.
This video covers:
00:14-13:00 - Cluster Versions(Kubeadm,Kubelet,Kubectl)
13:01-23:41 - Upgrade Kubeadm Cluster(Master Node)
23:42-25:25 - Upgrade Kubelet And Kubectl

Solid session, thanks for your hard work. Kindly note - control plane replaces master nodes - K8S official documents replaced all master to control plane.. in future session do take note.
Excellent Session
Glad you enjoyed it
Hi Atul, i see that something missed @25:13 (Video Time) shows Master node upgraded to 1.23.13 but if you see master node status is "Not Ready" and then you proceed with worker node upgrade.. Fine.
Here @25:24 (Video time) get nodes status showing Master node status is "ready".. Do we need to do anything to bring master node to "Ready" ? That you haven't explained in this video.
Ofcourse the video is excellent. Can you please let us know any step we missed in this video ? or it will come automatically in few minutes ?
Yes, It will automatically be in ready state. There is nothing missed in the video.
@@K21Academy understood. Thanks for the clarification
