Description

Learn the fundamentals and basic concepts of OpenShift that you will need to build a production deady OpenShift cluster and get started with deploying and managing Application.

Build a strong foundation in OpenShift and container orchestration with this tutorial for beginners.

  • Deploy OpenShift

  • Use TFTP/Booting deployment


A much required skill for any one in DevOps and Cloud Learning the fundamentals of OpenShift puts knowledge of a powerful PaaS offering at your fingertips. OpenShift is the next generation Application Hosting platform by Red Hat.

Content and Overview


In this guide we will perform an installation of Red Hat OpenShift Container Platform 4.12 on KVM Virtual Machines. OpenShift is a powerful, platform agnostic, enterprise-grade Kubernetes distribution focused on developer experience and application security. The project is developed and owned by Red Hat Software company. OpenShift Container Platform is built around containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux.

The OpenShift platform offers automated installation, upgrades, and lifecycle management throughout the container stack – from the operating system, Kubernetes and cluster services, to deployed applications. Operating system that will be used on both the Control plan and Worker machines is Red Hat CoreOS (RHCOS). The RHCOS OS includes the kubelet, which is the Kubernetes node agent, and the CRI-O container runtime optimized for Kubernetes workloads.
