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.

Core OpenShift Concepts

In the previous chapters, we covered Docker and Kubernetes basics and went through the OpenShift architecture. We know how to build the OpenShift lab environment, so now it is time to get our hands dirty and see how we can work with OpenShift's main resources.

This chapter goes over OpenShift core concepts, such as creating new applications with OpenShift pods, services, routes, projects, and users. This will give you foundational skills, which will be enough for you to run and manage your application container infrastructure in OpenShift.

After reading this chapter, you will have learned about the following topics:

  • Managing projects and namespaces in OpenShift
  • Managing regular users in OpenShift
  • Creating new applications in OpenShift
  • Managing pods in OpenShift
  • Managing services in OpenShift
  • Managing routes in OpenShift
