Kubernetes Secrets Handbook

Understanding Kubernetes Secrets Management

This chapter will provide you with a refresher about containers, as well as a comprehensive overview of Kubernetes and its Secrets management implementation. By the end of this first walk-through, all personas (developers, platform, and security engineers) will know how to design and implement these topics with a set of hands-on examples. While going through these examples, we will highlight the respective security concerns that this book will address by covering a series of use cases that will lead to a production-grade solution for hybrid multi-cloud scenarios, including the business continuity perspective.

In this chapter, we will cover the following topics:

  • Understanding Kubernetes’ origins and design principles
  • Setting up our first Kubernetes testing environment
  • Exploring Kubernetes Secret and ConfigMap objects
  • Analyzing why Kubernetes Secrets are important
  • Unveiling the challenges and risks associated...

Technical requirements

To complete the hands-on parts of this chapter, we will be leveraging a series of tools and platforms that are commonly used to interact with containers, Kubernetes, and Secrets management. For this first chapter, we will be setting up this environment together and ramping up with a friendly desktop graphical solution for the first set of examples. Don’t worry – we have you covered with our Code in Action and GitHub repository, which contains the macOS installation example. Here is the list of required tools:

  • Docker (https://docker.com) or Podman (https://podman.io) as a container engine. Both are OK, although I do have a personal preference for Podman as it offers benefits such as being daemonless for easy installation, rootless for added security, fully Open Container Initiative (OCI)-compliant, Kubernetes ready, and has the ability to integrate with systemd at the user level to autostart containers/Pods.
  • Podman Desktop (https://podman...

Understanding Kubernetes’ origins and design principles

While the evolution from one platform to another might be obvious, the compelling event and inner mechanics might not be. To safely handle sensitive data within Kubernetes, we have to understand both its historical and architectural evolutions. This will help us implement a secure production-grade environment for our critical business applications.

The next few sections will describe a series of concepts, explore and practice them with a simple container runtime and Kubernetes cluster, and establish their direct relationships with security concerns that this handbook will address.

Important note

While we expect you to perform the hands-on examples while reading along, we understand that you might not have the opportunity to do so. As such, we have provided briefings and debriefings for each hands-on example.

From bare metal to containers

Four decades ago, deploying applications was done on a physical server...

Summary

In this chapter, we introduced containers, Kubernetes, and Secrets. We provided an overview of the history so far, going through the concepts of bare metal, virtual machine, and container-based deployments. We had the opportunity to understand the benefits of containerization and introduce container orchestration engines. We learned more about Kubernetes and its components, which made it possible for us to run our first Kubernetes secret example and also have a deep dive into the Kubernetes components involved to facilitate secret usage. This helped us identify the security and robustness concerns that come with the usage of Kubernetes Secrets.

In the next chapter, we will focus on the different types of Kubernetes Secrets, their usages, and the cross-cutting concerns that Secrets come with, such as auditing and access permissions.

Description

Securing Secrets in containerized apps poses a significant challenge for Kubernetes IT professionals. This book tackles the critical task of safeguarding sensitive data, addressing the limitations of Kubernetes encryption, and establishing a robust Secrets management system for heightened security for Kubernetes. Starting with the fundamental Kubernetes architecture principles and how they apply to the design of Secrets management, this book delves into advanced Kubernetes concepts such as hands-on security, compliance, risk mitigation, disaster recovery, and backup strategies. With the help of practical, real-world guidance, you’ll learn how to mitigate risks and establish robust Secrets management as you explore different types of external secret stores, configure them in Kubernetes, and integrate them with existing Secrets management solutions. Further, you'll design, implement, and operate a secure method of managing sensitive payload by leveraging real use cases in an iterative process to enhance skills, practices, and analytical thinking, progressively strengthening the security posture with each solution. By the end of this book, you'll have a rock-solid Secrets management solution to run your business-critical applications in a hybrid multi-cloud scenario, addressing operational risks, compliance, and controls.

Who is this book for?

This handbook is a comprehensive reference for IT professionals to design, implement, operate, and audit Secrets in applications and platforms running on Kubernetes. For developer, platform, and security teams experienced with containers, this Secrets management guide offers a progressive path—from foundations to implementation—with a security-first mindset. You’ll also find this book useful if you work with hybrid multi-cloud Kubernetes platforms for organizations concerned with governance and compliance requirements.

Must say, I didn't have some high expectations of this book - I mean, Kubernetes secrets... it's not something you would write a book on, right? I was mistaken! Enjoyed every page of this book! The authors managed to discuss the Kubernetes secrets deep and wide, and have to say - it's the only book on the subject (that I know of) and it's so good! Everything that may interest you in regards to Kubernetes secrets is covered. From concepts to using and debugging them, either in the lab or production, either on-premises or in the cloud(s) - everything is covered! And to top it all - there are also practical, real-world cases and examples! Highly recommend this book if you're working with Kubernetes!
