Deploy and update applications from resource manifests that are parameterized for different target environments using Kustomize and Helm.
Deploy, update, and manage applications from resource manifests that are packaged for sharing and distribution across enterprise clusters.
Configure authentication with the HTPasswd identity provider. Map users and assign Role-Based Access Control (RBAC) to users and groups.
Protect network traffic between applications inside and outside the cluster. Implement strict network policies for multi-tenant traffic isolation.
Expose applications to external access without using a standard Ingress controller. Manage specialized routing and TLS configurations.
Configure clusters for safe self-service by developers from multiple teams. Enforce resource quotas, limit ranges, and project templates.
Install, configure, and update Operators that are managed by the Operator Lifecycle Manager (OLM) and Cluster Version Operator.
Run applications that require elevated or special privileges from the host Operating System or Kubernetes using Security Context Constraints (SCCs).
Update a live OpenShift cluster and its underlying CoreOS nodes while minimizing disruption to deployed production applications.
Everything you need to know about the DO280 EX280 training process.
DO180 is an introduction to Containers, Kubernetes, and OpenShift basics for developers. DO280 (OpenShift Administration II) is an advanced course for Ops and SREs, focusing heavily on cluster security, multi-tenancy, Operators, and Day 2 administration. DO280 directly prepares you for the EX280 exam.
Yes. OpenShift is Red Hat's enterprise Kubernetes distribution. A solid understanding of Kubernetes primitives (Pods, Deployments, Services, ConfigMaps) and Linux system administration (RHCSA level) is highly recommended before tackling DO280.
The EX280 is a 100% performance-based exam where you must fix, configure, and secure a broken OpenShift cluster. We provide dedicated, multi-node OpenShift 4.20 lab environments. You learn by doing, not by watching PowerPoints, ensuring you can troubleshoot under exam time pressure.
The EX280 is a rigorous 3-hour practical exam. You must score at least 210 out of 300 to earn the Red Hat Certified Specialist in OpenShift Administration credential.
