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.

Summary

The purpose of this chapter was to give you an idea of some of the real-world security considerations effecting many Kubernetes clusters.

We started out by looking at ways to secure the software delivery pipeline by discussing a number of image-related best practices. These included how to secure your image registries, scanning images for vulnerabilities, and cryptographically signing images. Then, we looked at some of the workload isolation options that exist at different layers of the infrastructure stack. In particular, we looked at cluster-level isolation, node-level isolation, and some of the different runtime isolation options. We talked about identity and access management, including places where additional security measures might be useful. We then talked about auditing, and finished up with a real-world issue that could be easily avoided by implementing some of the best practices already covered.

Hopefully, you now have enough understanding to go away and start...
