In the previous chapter, we described how to install an OpenShift cluster using an advanced installation method. The next step of the installation process is to make persistent storage available for OpenShift users. In Chapter 1, Containers and Docker Overview, we already how to use Docker persistent volumes. Usually, we do not need any for development or testing purposes, but it is not the case with production environments where we need to store persistent data in certain cases. In this chapter, we will describe the persistent storage concept regarding the OpenShift infrastructure. We will also explain the need for using persistent storage in a production environment. The focus of this chapter is all about configuring an infrastructure to support persistent storage. This includes the following storage types: NFS, GlusterFS, iSCSI, and more. Besides...

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.
