Course Overview

Configure and manage OpenShift clusters to maintain security and reliability across multiple applications and development teams.
Red Hat OpenShift Administration II: Configuring a Production Cluster (DO280) prepares OpenShift Cluster Administrators to perform daily administration tasks on clusters that host applications provided by internal teams and external vendors, enable self-service for cluster users with different roles, and deploy applications that require special permissions such as such as CI/CD tooling, performance monitoring, and security scanners.
This course focuses on configuring multi-tenancy and security features of OpenShift as well as managing OpenShift add-ons based on operators.
This course is intended to develop the skills needed to manage Red Hat OpenShift clusters and support containerized applications that are highly available, resilient, and scalable.
Red Hat OpenShift is an enterprise-hardened application platform based on Kubernetes that provides a common set of APIs and abstractions that enable application portability across cloud providers and traditional data centers. Red Hat OpenShift adds consistency and portability of operational processes across these environments and can also be deployed as a managed service.
A Red Hat SRE team shares the responsibility of managing Red Hat OpenShift clusters with a customer’s IT operations team when using a managed OpenShift offering such as Red Hat OpenShift on AWS (ROSA) or Azure Red Hat OpenShift (ARO).
The skills you learn in this course can be applied using all versions of OpenShift, including Red Hat OpenShift on AWS (ROSA), Azure Red Hat OpenShift, and OpenShift Container Platform.
This package (course + exam) is based on OpenShift Container Platform 4.18 and includes an exam voucher.
Note: Starting January 2026 this bundle (Course + Exam) only exists in CR (classroom) if scheduled or Closed course modalities.
If you are targeting a virtual class, please consider DO280LS the new RHLS-course subscription which includes as well an exam voucher.
