Pédagogie

Impact on the organization

This course provides novice administrators with the essential skills to configure and manage Red Hat OpenShift Container Platform clusters to support containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift Container Platform is an enterprise, hardened distribution of Kubernetes that enables rapid application development and deployment, as well as portability of applications and operational processes across cloud providers and traditional data centers.

Impact on the individual

After completing this course, you should be able to demonstrate the skills necessary to establish the health of a new OpenShift cluster, grant users and developers access to the cluster, and manage the cluster on a day-to-day basis. One major focus of the course is troubleshooting common problems that you might encounter beyond day one as users and applications use cluster resources.
