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

17. Advanced Scheduling in Kubernetes

Overview

This chapter focuses on scheduling, which is the process by which Kubernetes selects a node for running a Pod. In this chapter, we will take a closer look at this process and the Kubernetes Scheduler, which is the default Kubernetes component responsible for this process.

By the end of this chapter, you will be able to use different ways to control the behavior of the Kubernetes Scheduler to suit the requirements of an application. The chapter will equip you to be able to choose appropriate Pod scheduling methods to control which nodes you want to run your Pods on based on your business needs. You will learn about the different ways to control the scheduling of Pods on the Kubernetes cluster.
