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.

Application backup and recovery using Kasten

In this section, we will create disaster recovery backups and migrate Kubernetes applications and their persistent volumes in Kubernetes using Kasten (K10).

You will learn how to install and use K10, create standard and scheduled backups of applications to an S3 target, and restore them back to the Kubernetes clusters.

Getting ready

Make sure you have a Kubernetes cluster ready and kubectl and helm configured so that you can manage the cluster resources. In this recipe, we will use a three-node Kubernetes cluster on AWS.

This recipe requires an existing stateful workload with presentable data to simulate a disaster. To restore the data, we will use the mytestapp application we created in the Installing EBS CSI Driver to manage EBS volumes recipe in Chapter 5, Preparing for Stateful Workloads.
