OpenShift 4.19 Bare Metal Deployment Guide: Build Your Clust

Learn how to build, configure, and troubleshoot a production-grade OpenShift 4.19 cluster on your own infrastructure.

What you’ll learn
Deploy an OpenShift 4.x cluster on bare metal using User-Provisioned Infrastructure (UPI)
Configure DNS, HAProxy load balancing, and networking required for OpenShift installation
Generate and customize manifests, ignition configs, and install RHCOS nodes correctly.
Validate cluster health, approve CSRs, and troubleshoot bootstrap, API, and node issues.

Requirements
A basic understanding of Linux commands, networking concepts, and virtualization will help learners progress smoothly, but the course is designed so beginners can follow each step. Students should have access to a lab environment or virtual machines capable of running OpenShift bare-metal nodes, along with reliable internet access to download installation files and RHCOS images. No prior OpenShift experience is required, as every component—from DNS to HAProxy to ignition configuration—is explained in a practical, hands-on manner.

Description
Deploying OpenShift on bare metal is one of the most valuable skills an infrastructure or DevOps engineer can develop—and also one of the most challenging. This course gives you a complete, practical walkthrough of installing OpenShift 4.19 using User-Provisioned Infrastructure (UPI), starting from an empty environment and ending with a fully functioning production-grade cluster.You will learn how to configure every moving piece yourself: DNS, HAProxy load balancing, networking, Apache web services, ignition files, and RHCOS installations. Nothing is abstracted away. You’ll see how bootstrap works, how masters join the cluster, how workers register, and how to validate the health of all OpenShift components. Every step is demonstrated clearly so you understand not just what to do, but why it matters.Whether you’re an aspiring platform engineer, a systems administrator, or someone preparing for Red Hat certifications, this course gives you the real-world experience that teams expect. By the end, you will have built a complete OpenShift cluster with the same manual control used in enterprise environments—and you’ll know how to troubleshoot, validate, and maintain it with confidence.If you’ve ever wanted to truly understand OpenShift beyond cloud installers and managed services, this course opens that door with a practical, hands-on approach.

Who this course is for
This course is ideal for engineers, system administrators, DevOps practitioners, and IT professionals who want to build a complete OpenShift cluster on their own infrastructure. It’s also valuable for learners preparing for Red Hat certifications or anyone curious about how OpenShift works beneath the surface—DNS, load balancing, ignition, and bare-metal provisioning. Whether you’re managing enterprise platforms or exploring OpenShift for the first time, this course gives you the practical, step-by-step skills needed to deploy and operate a real cluster.
