Preface
OpenShift implements a polyglot platform for the deployment of web applications and
services. It uses containers in conjunction with a Security-Enhanced Linux (SELinux)
environment to implement a secure multitenant environment suitable for the enterprise.
You can deploy OpenShift in your own infrastructure or on public clouds, or you can
use OpenShift Online, Red Hat’s cloud-based hosting service.
The latest version of OpenShift uses the industry-standard Kubernetes platform from
the Cloud Native Computing Foundation (CNCF) for managing and running
applications within containers at scale. The ability to run any application image is
ensured through adherence to image and runtime specifications from the Open
Container Initiative (OCI).
OpenShift offers you the ability to easily deploy your web application code directly
using a library of predefined image builders, or you can bring your own container
images. With support in OpenShift for features such as persistent volumes, you are not
limited to just running stateless 12-factor or cloud-native applications. Using
OpenShift, you can also deploy databases and many legacy applications that you
otherwise would not be able to run on a traditional Platform as a Service (PaaS)
offering.
OpenShift is a complete container application platform. It is a modern take on the
traditional PaaS that you can use with your existing applications, but that also provides
the power and flexibility to meet future needs.
Who Should Read This Book
This book is intended for developers who are evaluating OpenShift, or have already
decided to use it, and who seek a more in-depth knowledge of the core features of
OpenShift that are used to deploy applications. It will also be of interest to
administrators who are managing an OpenShift cluster and who need to provide
assistance to developers using the platform.
The book is the third in a series of books from Red Hat about the latest version of
OpenShift. The prior books in the series are:
OpenShift for Developers: A Guide for Impatient Beginners
DevOps with OpenShift: Cloud Deployments Made Easy
