In this section, we will configure our Kubernetes cluster to get core metrics, such as CPU and memory. You will learn how to monitor Kubernetes metrics using the built-in Kubernetes tools both in the CLI and on the UI.
Getting ready
Make sure you have a Kubernetes cluster ready and kubectl configured to manage the cluster resources.
Clone the k8sdevopscookbook/src repository to your workstation to use the manifest files in the chapter8 directory:
$ git clone https://github.com/k8sdevopscookbook/src.git
$ cd /src/chapter8
