Working with Kubernetes

In this section, we’ll use real-world examples of interacting with a Kubernetes cluster. Since we’ll be using the kubectl CLI to a considerable extent, we’re going to take a deep dive into some of its more common usage patterns. Then, we will turn our focus to deploying applications to a Kubernetes cluster. We’ll be using the on-premises environment we built in the Installing Kubernetes on VMs section.
