The Kubernetes Book

By: Nigel Poulton, Pushkar Joglekar

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.

A Data Center OS

Generally speaking, containers make our previous scalability challenges look easy – we've just said that Google goes through billions of containers per week!

That's great, but not everybody is the size of Google. What about the rest of us?

Well, as a general rule, if your legacy apps have hundreds of VMs, there's a good chance your containerized cloud-native apps will have thousands of containers. With this in mind, we desperately need a way to manage them.

Say hello to Kubernetes.

Also, we live in a business and technology world that is increasingly fragmented and in a constant state of disruption. With this in mind, we desperately need a framework and platform that is ubiquitous and hides the complexity.

Again, say hello to Kubernetes.

When getting your head around something like Kubernetes it's important to understand modern data center architectures. For example, we're moving away from the traditional view of the...
