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.

Minikube

Minikube is another option if you're a developer and need a local Kubernetes development environment on your laptop. Like Docker Desktop, you get a local VM running a single-node Kubernetes cluster for development. It's not for production!

Note

I've had mixed results with Minikube. It's great when it works, but sometimes it's hard to get working. For this reason, I prefer Docker Desktop for Mac and Windows.

You can get Minikube for Mac, Windows, and Linux. We'll take a quick look at Mac and Windows, as this is what most people run on their laptops.

Note

Minikube requires virtualization extensions enabled on your system's BIOS.

Installing Minikube on Mac

It's probably a good idea to install kubectl (the Kubernetes client) before you install Minikube. You'll use this later to issue commands to the Minikube cluster:

  1. Use Brew to install kubectl:
       $ brew install kubernetes-cli
       Updating Homebrew...
