Red Hat OpenShift delivers a complete application platform for both traditional and cloud-native applications, allowing them to run anywhere. Built on Red Hat Enterprise Linux and compatible with Red Hat Ansible Automation Platform, Red Hat OpenShift enables automation inside and outside your Kubernetes clusters.
An IT professional who is a Red Hat® Certified Specialist in OpenShift Administration has demonstrated the skills, knowledge, and abilities needed to create, configure, and manage a cloud application platform using Red Hat OpenShift.
Red Hat OpenShift I: Containers & Kubernetes (DO180) introduces students to building and managing containers for deployment on a Kubernetes cluster. This course helps students build core knowledge and skills in managing containers through hands-on experience with containers, Kubernetes, and the Red Hat OpenShift Container Platform needed for multiple roles, including developers, administrators and site reliability engineers.
This course is based on Red Hat OpenShift® Container Platform 4.10.
Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280) teaches you how to configure, troubleshoot, and manage Red Hat® OpenShift® Container Platform. This hands-on, lab-based course shows you how to verify the successful installation of a cluster, manage it on a day-to-day basis, and troubleshoot the deployment of containerized applications.
This course is based on OpenShift Container Platform 4.10.
Red Hat OpenShift Administration III: Scaling Kubernetes Deployments in the Enterprise (DO380) expands upon the skills required to plan, implement, and manage OpenShift® clusters in the enterprise. You will learn how to support a growing number of stakeholders, applications, and users to achieve large-scale deployments.
This course is based on Red Hat® OpenShift Container Platform 4.6.
