Overview of this book

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.

Walking through Kubernetes Secrets Management Concepts

In the previous chapter, we had a good overview of Kubernetes, the components that Kubernetes consists of, and how configurations are applied and stored. Also, we built a Golang application and managed to run this application on Kubernetes. As expected, Secrets had to be added to our application’s configuration. Secrets management comes with various concerns. From creation to modification to deletion, we need to tackle security concerns as well as scalability and resiliency.

In this chapter, we will cover the following topics:

  • What are Kubernetes Secrets, and how do they differ from other Kubernetes objects?
  • Different types of Secrets and their usage scenarios
  • Creating, modifying, and deleting Secrets in Kubernetes
  • Kubernetes Secrets configuration in different deployment scenarios
  • Requirement for managing Secrets, including secure storage and access control
  • Securing access to Secrets with RBAC...
