Red Hat OpenShift Administration II: Configuring a Production Cluster

• System Administrators who need to manage OpenShift clusters, applications, users, and add-ons.
• Site Reliability Engineers who need to maintain and troubleshoot Kubernetes clusters.
• System and Software Architects who need to understand the security of an OpenShift cluster.

Organizations that share OpenShift clusters across multiple teams risk operational bottlenecks when platform engineers cannot safely delegate self-service access. Organizations also risk security exposure when privileged infrastructure applications, such as CI/CD tools, monitoring, and security scanners are not correctly isolated from business workloads. This course prepares administrators to configure the multitenancy guardrails, security policies, declarative deployment workflows, and advanced networking capabilities that enable teams to operate independently at speed and to keep shared clusters secure, reproducible, and production-ready.

After completing this course, students can configure multitenant Red Hat OpenShift Container Platform clusters by managing authentication, authorization, resource quotas, and security policies for multiple teams. Students can also deploy applications by using declarative workflows, secure network traffic, expose non-HTTP services, install and manage operators, and update clusters.

• The Red Hat OpenShift Administration I: Operating a Production Cluster (DO180 v4.22) course, or equivalent skills in deploying and managing Kubernetes applications by using the OpenShift web console and command-line interfaces.
• Intermediate skills in operating a Bash shell, including command-line text processing, text editing, and Linux networking and security utilities. Students are encouraged to take the Red Hat System Administration I (RH124) course before enrolling in DO280.

We recommend completing our no-cost skills assessment before enrolling in any Red Hat Training or Certification.  Learn more.
