Overview of this book

Thanks to its extensive support for managing hundreds of containers that run cloud-native applications, Kubernetes is the most popular open source container orchestration platform that makes cluster management easy. This workshop adopts a practical approach to get you acquainted with the Kubernetes environment and its applications. Starting with an introduction to the fundamentals of Kubernetes, you’ll install and set up your Kubernetes environment. You’ll understand how to write YAML files and deploy your first simple web application container using Pod. You’ll then assign human-friendly names to Pods, explore various Kubernetes entities and functions, and discover when to use them. As you work through the chapters, this Kubernetes book will show you how you can make full-scale use of Kubernetes by applying a variety of techniques for designing components and deploying clusters. You’ll also get to grips with security policies for limiting access to certain functions inside the cluster. Toward the end of the book, you’ll get a rundown of Kubernetes advanced features for building your own controller and upgrading to a Kubernetes cluster without downtime. By the end of this workshop, you’ll be able to manage containers and run cloud-based applications efficiently using Kubernetes.

Preface

5. Pods

Overview

This chapter introduces the concept of pods and teaches how to properly configure and deploy them. We will begin by creating a simple pod with your application container running in it. We will explain what the different aspects of pod configuration mean and decide which configuration to use based on your application or use case. You will be able to define resource allocation requirements and limits for pods. We will then move on to see how we can debug the pod, check the logs, and make changes to it when needed. Some more useful tools for managing faults in pods, such as liveness and readiness probes and restart policies, are also covered in this chapter.
