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.

Summary

In this chapter, we explored the critical concepts of authentication and authorization in OpenShift. We began by understanding the importance of these security mechanisms and how they form the foundation of protecting your cluster. We then delved into OpenShift's OAuth system, covering its key components and how they interact with authentication providers. We also examined RBAC, including how users, groups, and service accounts are managed to enforce security policies.Additionally, we discussed ServiceAccounts in more detail – what they are in general and the default one in particular. At this point, you should have a solid grasp of how to implement and manage authentication and authorization in your OpenShift environment.In the next chapter, we'll move from security to performance, exploring how to scale your applications and infrastructure with OpenShift. You'll learn to keep your environment responsive and efficient as demand grows.
