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.

Tools and solutions for backing up Kubernetes Secrets

Several tools and solutions exist to help users back up Secrets in a Kubernetes environment. The right one for users depends on the specific setup, requirements, and preferences. We will examine the tools that are available and how they can be combined with our infrastructure decisions.

Velero

Velero is a popular open source tool for managing disaster recovery and migrating Kubernetes cluster resources and persistent volumes. Velero allows users to back up and restore Kubernetes objects and persistent volumes.

Sample configuration for Velero backup is as follows:

apiVersion: velero.io/v1
kind: BackupStorageLocation
metadata:
  name: aws
  namespace: velero
spec:
  provider: aws
  objectStorage:
    bucket: myBucket
  config:
    region: us-west-2
