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.

OpenShift as an extension of Kubernetes

In previous chapters, we looked at how Kubernetes can simplify the management of Docker containers and take care of container deployment. Kubernetes brings additional value to container management across multiple nodes, which is very important in modern highly available and distributed infrastructure. Despite all the advantages Kubernetes has, it has drawbacks, and most of them are rectified by OpenShift.

OpenShift is a PaaS offering from Red Hat that natively integrates Docker and Kubernetes to create a powerful container cluster management and orchestration system. OpenShift encompasses the architecture, processes, platforms, and services needed to empower developers and operations teams. OpenShift increases reliability across all environments and meets all customer requirements while reducing infrastructure costs.
