📌 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.
