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.

Installing Kubernetes

In this chapter, we'll look at a few different ways to install Kubernetes.

Things have changed a lot since I wrote the first edition of the book in July 2017. Back then, installing Kubernetes was hard. These days, it's a lot easier. In fact, we're approaching the point where we can just ask for a Kubernetes cluster and get one – a zero-effort Kubernetes cluster. This is especially true with hosted Kubernetes services such as Azure Kubernetes Service (AKS) and Google Kubernetes Engine (GKE).

On the topic of hosted Kubernetes services… More and more companies are choosing to use hosted Kubernetes services, and with things such as GKE On-Prem (https://cloud.google.com/gke-on-prem/), it's looking increasingly likely that a large number of Kubernetes clusters will be built and managed via the major cloud providers.

With all of this in mind, ask yourself the following question before building your own Kubernetes cluster...
