Topic Content

Storage encompasses the fundamental concepts and practical implementation of data persistence in containerized environments. This includes mastering storage classes and persistent volumes as the core infrastructure for managing stateful data, along with understanding the critical parameters that govern volume behavior such as volume modes, access modes, and reclaim policies that determine how data is stored and retained. Learners must grasp the persistent volume claims primitive, which serves as the mechanism for applications to request and consume storage resources dynamically. Additionally,... See More

Task

Given an existing Kubernetes cluster running version 1.20.0, upgrade all of the Kubernetes control plane and node components on the master node only to version 1.20.1.

Be sure to drain the master node before upgrading it and uncordon it after the upgrade.

You are also expected to upgrade kubelet and kubectl on the master node.
