Already know Kubernetes? This guide teaches you the OpenShift part. OpenShift Administration for Kubernetes Engineers is a hands-on study guide for the Red Hat Certified Specialist in OpenShift Administration exam (EX280), covering the OpenShift Container Platform 4.14 to 4.18 objectives. It is written for engineers who already run Kubernetes and don't need Pods, Services and RBAC explained again. Instead, every chapter focuses on what OpenShift adds or changes, and on the fastest way to get each task done with the oc command line. Inside you will learn to: - Configure HTPasswd authentication, manage users and groups, and apply role-based access control - Deploy applications from manifests, Kustomize overlays, OpenShift templates and Helm charts - Manage secrets, config maps, persistent storage, storage classes and stateful sets - Configure health probes, resource limits and autoscaling - Use image streams, triggers and rollbacks to manage application updates - Create self-signed certificates and secure routes with edge, passthrough and reencrypt TLS - Write network policies and expose non-HTTP applications with MetalLB and Multus - Set up quotas, limit ranges and project templates for developer self-service - Install, approve, update and remove operators with OLM - Control access with service accounts and Security Context Constraints - Update OpenShift clusters and find deprecated API usage Each topic includes working commands, ready-to-use YAML, and tips on the mistakes that commonly cost candidates points. The book finishes with a 20-task timed practice exam with full solutions, a command quick reference, and a final-week checklist. Whether you are preparing for EX280 or running OpenShift in production, this book turns your Kubernetes experience into OpenShift skill.
