Containers, Kubernetes, and Red Hat OpenShift Administration II (DO285)

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) help you gain core knowledge in building and managing Linux® containers, and in configuring and managing Red Hat® OpenShift® Container Platform clusters. 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 4.6 and combines contents from Red Hat OpenShift I: Containers & Kubernetes (DO180) and Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280).
