Kubernetes - A Complete DevOps Cookbook

By: Murat Karslioglu

Overview of this book

Kubernetes is a popular open source orchestration platform for managing containers in a cluster environment. With this Kubernetes cookbook, you’ll learn how to implement Kubernetes using a recipe-based approach. The book will prepare you to create highly available Kubernetes clusters on multiple clouds such as Amazon Web Services (AWS), Google Cloud Platform (GCP), Azure, Alibaba, and on-premises data centers. Starting with recipes for installing and configuring Kubernetes instances, you’ll discover how to work with Kubernetes clients, services, and key metadata. You’ll then learn how to build continuous integration/continuous delivery (CI/CD) pipelines for your applications, and understand various methods to manage containers. As you advance, you’ll delve into Kubernetes' integration with Docker and Jenkins, and even perform a batch process and configure data volumes. You’ll get to grips with methods for scaling, security, monitoring, logging, and troubleshooting. Additionally, this book will take you through the latest updates in Kubernetes, including volume snapshots, creating high availability clusters with kops, running workload operators, new inclusions around kubectl and more. By the end of this book, you’ll have developed the skills required to implement Kubernetes in production and manage containers proficiently.

Monitoring in Kubernetes

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
$ cd /src/chapter8

The Monitoring metrics using Kubernetes Dashboard recipe requires Kubernetes Dashboard v2.0.0 or later to function. If you want to add metric functionality to the dashboard, make sure that you have Kubernetes Dashboard installed by following the instructions in the Deploying Kubernetes Dashboard recipe in Chapter 1, Building Production-Ready Kubernetes Clusters.
