Course Overview
Containers, Kubernetes, and Red Hat OpenShift Administration II (DO285) - 4.6 by Red Hat is a hands-on, lab-based course designed for system administrators, cluster operators, and site reliability engineers responsible for managing enterprise-grade OpenShift clusters. It prepares learners for the Red Hat Certified Specialist in OpenShift Administration exam (EX280), a performance-based certification validating real-world operational skills. This course builds core competencies in deploying, configuring, and managing Red Hat OpenShift Container Platform 4.6, enabling professionals to support scalable, secure containerized applications. With 95% of Fortune 100 companies adopting container technologies like Kubernetes and OpenShift, this training addresses critical industry demand for skilled administrators who can maintain resilient cloud-native infrastructure beyond initial deployment.
The course emphasizes practical experience with key technologies including Podman, Kubernetes, Red Hat OpenShift Container Platform, OpenShift Virtualization (KubeVirt), Source-to-Image (S2I), and OpenShift Container Storage (OCS). Students work in a dedicated lab environment based on OpenShift 4.6 UPI installations, where they build and validate clusters on virtualized bare-metal infrastructure. Through intensive labs, participants configure masters and nodes, deploy multi-container applications using custom images, implement authentication via HTPasswd, manage role-based access control, and troubleshoot networking issues. A key hands-on project involves deploying OpenShift Virtualization to run traditional virtual machines alongside containers, performing live migrations, and integrating storage and network policies—mirroring real-world hybrid workload scenarios in production environments.
By completing Containers, Kubernetes, and Red Hat OpenShift Administration II (DO285) - 4.6, professionals gain direct preparation for the widely recognized EX280 certification, which contributes to achieving Red Hat Certified Architect status. Certified OpenShift administrators report average salary increases of 20–30%, with mid-level roles commanding $110,000–$140,000 annually in North America. Koenig Solutions enhances this path with Guaranteed-to-Run scheduling, official Red Hat courseware, and optional 1-on-1 mentoring, ensuring consistent access to high-quality training. Graduates emerge ready to lead OpenShift cluster operations, drive digital transformation initiatives, and support enterprise DevOps adoption across hybrid and multicloud environments.
