Overview of this book

Kubernetes is an open source orchestration platform for managing containerized applications. Despite widespread adoption of the technology, DevOps engineers might be unaware of the pitfalls of containerized environments. With this comprehensive book, you'll learn how to use the different security integrations available on the Kubernetes platform to safeguard your deployments in a variety of scenarios. Learn Kubernetes Security starts by taking you through the Kubernetes architecture and the networking model. You'll then learn about the Kubernetes threat model and get to grips with securing clusters. Throughout the book, you'll cover various security aspects such as authentication, authorization, image scanning, and resource monitoring. As you advance, you'll learn about securing cluster components (the kube-apiserver, CoreDNS, and kubelet) and pods (hardening image, security context, and PodSecurityPolicy). With the help of hands-on examples, you'll also learn how to use open source tools such as Anchore, Prometheus, OPA, and Falco to protect your deployments. By the end of this Kubernetes book, you'll have gained a solid understanding of container security and be able to protect your clusters from cyberattacks and mitigate cybersecurity threats.

Summary

The trend of microservices and the rise of Docker has enabled Kubernetes to become the de facto platform for DevOps to deploy, scale, and manage containerized applications. Kubernetes abstracts storage and computing resources as Kubernetes objects, which are managed by components such as kube-apiserver, kubelet, etcd, and so on.

Kubernetes can be created in a private data center or on the cloud or hybrid. This allows DevOps to work with multiple cloud providers and not get locked down to any one of them. Although Kubernetes is in GA as of 2018, it is still young and evolving very fast. As Kubernetes gets more and more attention, the attacks targeted at Kubernetes also become more notable.

In the next chapter, we are going to cover the Kubernetes network model and understand how microservices communicate with each other in Kubernetes.
