Auth Considerations for Kubernetes

About the Book

What aspects of authentication and authorization do you need to think about when you are building applications on Kubernetes, the popular open-source orchestration platform? This book will dig into the different kids of auth present in Kubernetes, some examples of how to implement auth using Istio and other tools, and ways to pass identity and authorization data between different areas of your application. It'll also give you a step by step guide to setting up an OIDC server to manage access to the underlying infrastructure (pods, nodes, etc) of your Kubernetes cluster.
