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.

Automating Chaos Engineering with Gremlin

Gremlin is a Chaos Engineering service that prevents outages and builds more reliable systems. In this section, we will run chaos attacks in production to validate the resiliency of the systems using Gremlin. You will learn how to create CPU and node shutdown attacks to test the resiliency of your infrastructure.

Getting ready

For this recipe, we need to have the Kubernetes command-line tool, kubectl, and helm installed.

All the operations mentioned here require a Gremlin account. If you don't have one, go to and create one.

How to do it…

This section is further divided into the following subsections to make this process easier:

  • Setting up Gremlin credentials
  • Installing Gremlin on Kubernetes
  • Creating a CPU attack against a Kubernetes worker
  • Creating a node shutdown attack against a Kubernetes worker
  • Running predefined scenario-based attacks
  • Deleting Gremlin from your cluster
