Getting Started with Kubernetes, Second Edition - Second Edition

By: Jonathan Baier

Overview of this book

Kubernetes has continued to grow and achieve broad adoption across various industries, helping you to orchestrate and automate container deployments on a massive scale. This book will give you a complete understanding of Kubernetes and how to get a cluster up and running. You will develop an understanding of the installation and configuration process. The book will then focus on the core Kubernetes constructs such as pods, services, replica sets, replication controllers, and labels. You will also understand how cluster level networking is done in Kubernetes. The book will also show you how to manage deployments and perform updates with minimal downtime. Additionally, you will learn about operational aspects of Kubernetes such as monitoring and logging. Advanced concepts such as container security and cluster federation will also be covered. Finally, you will learn about the wider Kubernetes ecosystem with OCP, CoreOS, and Tectonic and explore the third-party extensions and tools that can be used with Kubernetes. By the end of the book, you will have a complete understanding of the Kubernetes platform and will start deploying applications on it.

Vulnerability management is a critical component of any modern day IT operation. Zero-day vulnerabilities are on the rise and even those vulnerabilities with patches can be cumbersome to remediate. First, application owners must be made aware of their vulnerabilities and potential patches. Then these patches must be integrated into systems and code and often this requires additional deployments or maintenance windows. Even when there is visibility to vulnerabilities, there is often a lag in remediation, often taking large organizations several months to patch.

While containers greatly improve the process of updating applications and minimizing downtime, there still remains a challenge inherent in vulnerability management. Especially since an attacker only needs to expose one such vulnerability; making anything less than 100% of systems patched is a risk for compromise. 

What's needed is a faster feedback loop in addressing vulnerabilities. Continuous scanning and tying into...
