This introductory guide will get you up to speed with kubectl in no time. The book is divided into four parts, touching base on the installation and providing a general overview of kubectl in the first part. The second part introduces you to managing Kubernetes clusters and working with nodes. In the third part, you’ll be taken through the different ways in which you can manage Kubernetes applications, covering how to create, update, delete, view, and debug applications. The last part of the book focuses on various Kubernetes plugins and commands. You’ll get to grips with using Kustomize and discover Helm, a Kubernetes package manager. In addition to this, you’ll explore how you can use equivalent Docker commands in kubectl.

Chapter 10: kubectl Best Practices and Docker Commands

In the previous chapter, we learned about Helm, which is a Kubernetes package manager. In this last chapter of our book, we are going to learn about a few kubectl best practices.

In this chapter, we will learn how to use shell aliases to shorten kubectl commands, and other handy tips for using kubectl commands, as well.

We will also check some equivalent commands in Docker for some kubectl commands, especially the ones that are handy to know for new Kubernetes users who are familiar with Docker commands and want to know about similar commands in kubectl.

In this chapter, we're going to cover the following main topics:

  • Using shell aliases for kubectl commands
