Overview of this book

For IT professionals working with Red Hat OpenShift Container Platform, the key to maximizing efficiency is understanding the powerful and resilient options to maintain the software development platform with minimal effort. OpenShift Multi-Cluster Management Handbook is a deep dive into the technology, containing knowledge essential for anyone who wants to work with OpenShift. This book starts by covering the architectural concepts and definitions necessary for deploying OpenShift clusters. It then takes you through designing Red Hat OpenShift for hybrid and multi-cloud infrastructure, showing you different approaches for multiple environments (from on-premises to cloud providers). As you advance, you’ll learn container security strategies to protect pipelines, data, and infrastructure on each layer. You’ll also discover tips for critical decision making once you understand the importance of designing a comprehensive project considering all aspects of an architecture that will allow the solution to scale as your application requires. By the end of this OpenShift book, you’ll know how to design a comprehensive Red Hat OpenShift cluster architecture, deploy it, and effectively manage your enterprise-grade clusters and other critical components using tools in OpenShift Plus.

AuthN and AuthZ

AuthN and AuthZ are related concepts but with different goals. AuthN is an abbreviation of authentication and is related to the process to confirm who a user is and validate their credentials to grant access to the platform. In this process, we deal with identity providers (IdPs) on OpenShift to configure the authentication provider that will check the user credentials, which we will cover shortly.

In turn, AuthZ stands for authorization and is directly linked to giving the user only what they really should have access to, after the authentication process.

These two concepts are seen as confusing or similar from the point of view of just logging in to OpenShift. To clarify the concepts, we will now discuss the different objects and processes related to authentication and authorization.

Authentication

OpenShift works with the following set of objects as part of the authentication process:

These are the objects used in OpenShift...
