GL390 - OpenShift Administration

This hands-on course with lab exercises will help learners to install and manage an OpenShift cluster. Throughout the course learners will understand the benefits and purposes of the platform. This includes how to install the cluster, explore networking concepts, understand commands, manage OpenShift resources, configure storage, manage application deployments, and administer the cluster through logging and monitoring.

Version: B00

Prerequisites:

Learners will need a working knowledge of Linux systems administration skills or the equivalent knowledge of skills found in the GL120 - Linux Fundamentals and GL250 - Enterprise Linux Systems Administration courses. Also learners will benefit from an understanding of containerization as found in the GL340 - Docker course.
