Overview of this book

Docker containers transform application delivery technologies to make them faster and more reproducible, and to reduce the amount of time wasted on configuration. Managing Docker containers in the multi-node or multi-datacenter environment is a big challenge, which is why container management platforms are required. OpenShift is a new generation of container management platforms built on top of both Docker and Kubernetes. It brings additional functionality to the table, something that is lacking in Kubernetes. This new functionality significantly helps software development teams to bring software development processes to a whole new level. In this book, we’ll start by explaining the container architecture, Docker, and CRI-O overviews. Then, we'll look at container orchestration and Kubernetes. We’ll cover OpenShift installation, and its basic and advanced components. Moving on, we’ll deep dive into concepts such as deploying application OpenShift. You’ll learn how to set up an end-to-end delivery pipeline while working with applications in OpenShift as a developer or DevOps. Finally, you’ll discover how to properly design OpenShift in production environments. This book gives you hands-on experience of designing, building, and operating OpenShift Origin 3.9, as well as building new applications or migrating existing applications to OpenShift.

Authentication and Authorization

In any secure system, knowing who is accessing your environment and what they are allowed to do is crucial. In OpenShift, this is managed through authentication and authorization processes. Authentication ensures that only legitimate users can access the cluster, while authorization determines what actions those users can perform once authenticated. Together, these mechanisms protect your OpenShift environment from unauthorized access and potential security threats. Let's talk about Authentication and Authorization and ensure we are on the same page.

Authentication

Authentication controls initial access to The Red Hat OpenShift Container Platform cluster by verifying the identity of the client that sends a request to the API server. Only clients that can prove their identity are allowed to proceed to the authorization phase.OCP's built-in OAuth server issues bearer access tokens, and the API server also accepts X.509 client certificates (commonly...
