DO280 – Red Hat OpenShift Administration II: Configuring a Production Cluster

Course description

Configure, manage, and troubleshoot OpenShift clusters and containerized applications

Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280) prepares OpenShift Cluster Administrators to perform daily administration tasks on clusters that host applications provided by internal teams and external vendors, enable self-service for cluster users with different roles, and deploy applications that require special permissions such as such as CI/CD tooling, performance monitoring, and security scanners.

DO280 focuses on configuring multi-tenancy and security features of OpenShift. DO280 also teaches how to manage OpenShift add-ons based on operators.

This course is based on OpenShift Container Platform 4.12.
