Overview of this book

Kubernetes is the leading orchestrator of cloud-native apps. With knowledge of how to work with Kubernetes, you can easily deploy and manage applications on the cloud or in your on-premises data center. The book begins by introducing you to Kubernetes and showing you how to install it. You’ll learn how to use Kubernetes Services and bring stable and reliable networking to apps that are deployed on Kubernetes. You'll delve deep into the powerful storage subsystem of Kubernetes and learn how to leverage the variety of external storage backends in your applications. As the book progresses, it shows you how to use features such as DaemonSets, Helm, and RBAC to enhance your Kubernetes applications. You'll explore the six categories of identifying vulnerabilities and look at a few ways to prevent and mitigate them. You'll also look at ways to secure the software delivery pipeline by discussing some image-related best practices. The book ends by sharing with you some resources that’ll help take your Kubernetes knowledge to the next level. By the end of the book, you’ll have the confidence and skills to leverage all the features of Kubernetes to develop scalable applications.

Docker Desktop

In my opinion, Docker Desktop is the best way to get a local development cluster on your Mac or Windows laptop. With a few easy steps, you get a single-node Kubernetes cluster that you can develop and test with. I use it nearly every day.

It works by creating a virtual machine (VM) on your laptop and starting a single-node Kubernetes cluster inside that VM. It also configures your kubectl client with a context that allows it to talk to the cluster. Finally, you get a simple GUI that lets you perform basic operations such as switching between all of your kubectl contexts.

Note

A kubectl context is a bunch of settings that the kubectl command uses to know which cluster to issue commands to.

Here are the steps:

  1. Point your web browser to www.docker.com and choose Products > Docker Desktop.
  2. Click the download button for either Mac or Windows.

    You may need to log in to the Docker Store. Creating an account is free, and so is the product.

  3. Open...
