Ready to build cloud native applications? Get a rapid, hands-on introduction to daily life as a developer whose code runs on OpenShift, the open source container application platform from Red Hat. Creating and containerizing your apps for deployment on modern distributed systems can be daunting. With this practical guide, developers will learn how to build, deploy, and manage a multitiered application on OpenShift.
OpenShift’s job is to give your applications a distributed computing cluster to run on without forcing you to become a distributed systems expert. Translated into jargon, that means OpenShift is a Platform as a Service (PaaS). OpenShift comes with tools for building applications from source in composable pipelines. It adds a browser-based graphical interface, the OpenShift Web Console, for deploying and managing workloads. You can point and click to set up network connections, monitoring and alerts, and rules for automatically scaling workloads. An OpenShift cluster applies software updates to itself and its nodes without cluster downtime.
OpenShift is a product from Red Hat. You can run it on your laptop; on a cluster of physical or virtual machines; on all the major cloud providers; and as a managed service. Like most software from Red Hat, OpenShift is developed as an open source project, the OpenShift Kubernetes Distribution (OKD). OpenShift is in turn built atop two open source keystones: application containers and the Kubernetes container orchestrator.
Containers are OpenShift’s atomic unit of execution. Each running instance of a container is stamped from an Open Container Initiative (OCI) image that packages an application executable with the dependencies it needs to run. Dependencies can include shared libraries, auxiliary programs, language runtimes, and anything else the application requires. Such a self-contained parcel is easier to distribute among a team, in a continuous series of releases on a server, and to arbitrary nodes in a cluster.
OpenShift is a distribution of Kubernetes, an open source software project started at Google and developed by a group of companies and individuals since its release in 2014. That community has since adopted formal governance through the Cloud Native Computing Foundation (CNCF). Kubernetes succeeds and inherits from Borg, Google’s internal system for scheduling billions of software containers on its massive clusters. Red Hat has been a leading contributor to Kubernetes since the project began, and OpenShift is developed in collaboration with the Kubernetes community.
