The Kubernetes Workshop

By: Zachary Arnold, Sahil Dua, Wei Huang, Faisal Masood, Mélony Qin, Mohammed Abu Taleb

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

Summary

This chapter demystified how kubectl allows us to control our Kubernetes cluster using API calls. First, we learned how to set up an environment for kubectl commands and looked at a number of shortcuts. Furthermore, we covered how to create, edit, and delete a Kubernetes object using kubectl commands and looked at a Deployment as an example. Finally, we deployed a real-life application and showed you how to edit a live Deployment. Every example in this chapter has been applied in a general context; however, we believe that the skills developed in this chapter can help you resolve specific problems that you might encounter in a professional environment.

In the next chapter, you'll explore the other side of this bridge and dive deeper into how the API server works. You will also take a closer look at REST API requests and how the API server deals with them.
