Chapter 2: Getting Information about a Cluster

When you are managing a Kubernetes cluster, it is necessary to know what Kubernetes version it is running on, the details about the master (also called the control plane), any addons installed on the cluster, and the available APIs and resources. As different Kubernetes versions support different API versions for resources, not setting the right/unsupported API version for your, for example, Ingress, will cause the deployment to fail.

In this chapter, we're going to cover the following topics:

Cluster information
Cluster API versions
Cluster API resources
