Course Description

Duration 5 days – 35 hrs

Overview

The Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (OCP v4.18) Training Course is an advanced, hands-on training program designed for IT professionals responsible for administering and operating enterprise-grade OpenShift Kubernetes environments.

This course focuses on managing and securing production OpenShift clusters using Red Hat OpenShift Container Platform (OCP) v4.18. Participants will learn how to implement declarative resource management, deploy packaged applications, configure authentication and authorization, secure networking, manage operators, enable developer self-service, and perform cluster maintenance and updates.

Through guided exercises, labs, and comprehensive reviews, participants will gain practical experience in operating scalable, secure, and highly available Kubernetes environments in production settings.
