Overview

Learn to build and manage container images, administrate an OpenShift cluster, and troubleshoot applications running on Kubernetes

Containers, Kubernetes, and Red Hat OpenShift Administration II (DO285) helps you gain core knowledge in building and in configuring and managing Red Hat® OpenShift® Container Platform. This immersive and intensive, hands-on course shows you how to deploy applications to a local container engines and OpenShift clusters, manage the cluster on a day-to-day basis, and troubleshoot the deployment of containerized applications.

This course is based on Red Hat OpenShift Container Platform 4.5 and combines the content from Red Hat OpenShift I: Containers & Kubernetes (DO180) and Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280).
