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.

Working with Minishift

Minishift is another way to deploy OpenShift locally, by running a single-node OpenShift cluster inside a virtual machine. Recently, we showed you how to use Minikube to deploy a development environment for Kubernetes. Minishift uses the same approach, because it was developed by Kubernetes community as a continuation of Minikube, mentioned in the Chapter 2, Kubernetes Overview, so it uses the same command line syntax. Minishift deployment is supported on the Windows, macOS, and Linux operating systems. Minishift uses libmachine to provision a virtual machine, boot2docker as OS, and OpenShift Origin to run the cluster. Minishift requires a hypervisor to run the virtual machine containing OpenShift.

Depending on your host operating system, you have a choice between the following hypervisors:

Operating system Hypervisor Platform
macOS xhyve VirtualBox...
