Overview of this book

The kubectl command line tool lets you control Kubernetes clusters to manage nodes in the cluster and perform all types of Kubernetes operations. 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. By the end of this book, you’ll have learned how to install and update an application on Kubernetes, view its logs, and inspect clusters effectively.

Using plugins

So, we have installed a few very useful plugins. Let's check out how to use them.

We have installed three plugins:

  • kubectl ctx: This plugin allows us to easily to switch between Kubernetes clusters, which is very useful when you have more than one cluster set in your kubeconfig.

    Lets' check for available cluster by running the $ kubectl ctx command:

  • kubectl ns: This plugin allows us to switch between namespaces. Let's check for available namespaces in the cluster by running the $ kubectl ns command:

Figure 7.5 – The ns plugin

  • kubectl view-allocations: This plugin lists resource allocations of a namespace, such as CPU, memory, storage, and so on.

    Let's check for resources allocations in the cluster by running the $ kubectl view-allocations command:
