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.

Building Production-Ready Kubernetes Clusters

This chapter proposes the most common deployment methods that are used on popular cloud services as well as on-premises, although you will certainly find a number of other tutorials on the internet explaining other approaches. This chapter explains the differences between managed/hosted cloud services versus self-managed cloud or on-premises Kubernetes deployments and the advantages of one vendor over another.

In this chapter, we will be covering the following recipes:

  • Configuring a Kubernetes cluster on Amazon Web Services
  • Configuring a Kubernetes cluster on Google Cloud Platform
  • Configuring a Kubernetes cluster on Microsoft Azure
  • Configuring a Kubernetes cluster on Alibaba Cloud
  • Configuring and managing Kubernetes clusters with Rancher
  • Configuring Red Hat OpenShift
  • Configuring a Kubernetes cluster using Ansible
  • Troubleshooting installation issues
