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.

What is New in OpenShift 3.9?

In the previous chapter, we covered the main network aspects while designing OpenShift clusters in one or across multiple data centers. We also discussed commonly made mistakes, solutions, and overall guidance from a networking point of view.

In this chapter, we are going to give a brief overview of the new OpenShift 3.9 features that we have and have not covered in this book. We are going to briefly discuss what to expect from the following OpenShift releases later in 2018.

In this chapter, we will cover the following topics:

  • Major changes in OpenShift 3.9
  • What to expect from the following OpenShift releases
