Red Hat OpenShift Administrator I: Operating a Production Cluster with Exam
Red Hat OpenShift Administration I: Operating a Production Cluster (DO180) prepares OpenShift cluster administrators to manage Kubernetes workloads and to collaborate with developers, DevOps engineers, system administrators, and SREs to ensure the availability of application workloads. The course focuses on managing typical end-user applications that are often accessible from a web or mobile UI and that represent most cloud-native and containerized workloads, including deploying and updating their dependencies such as databases, messaging, and authentication systems. The skills learners gain apply across all versions of OpenShift, including Red Hat OpenShift on AWS (ROSA), Azure Red Hat OpenShift, and OpenShift Container Platform. This course is based on Red Hat OpenShift 4.14.
Primary: Platform Engineers, System Administrators, Cloud Administrators, and other infrastructure-related IT roles who are responsible for tier-1 support of infrastructure for applications and who are interested in managing OpenShift clusters and containerized applications. Secondary: Enterprise Architects, Site Reliability Engineers, DevOps Engineers, and other application-related IT roles who are responsible for designing infrastructure for applications.
This course develops the skills needed to manage Red Hat OpenShift clusters and support containerized applications that are highly available, resilient, and scalable, giving organizations a consistent, portable way to operate Kubernetes-based workloads across cloud providers and traditional data centers. Learners will come away understanding the architecture of Red Hat OpenShift clusters and Kubernetes applications, and will be able to deploy, manage, and troubleshoot applications on OpenShift — including identifying and escalating application and infrastructure issues to development teams, operations teams, and IT vendors.
