Course Description

Introduction to building and managing docker containers for deployment on a Kubernetes cluster

Containers, Kubernetes, and Red Hat OpenShift Administration I (DO285) helps you build core knowledge and skills in managing containers through hands-on experience with Docker, Kubernetes, and the Red Hat® OpenShift® Container Platform.

This course is based on Red Hat OpenShift Container Platform 3.9 and Red Hat® Enterprise Linux® 7.5. DO285 combines the content from Introduction to Containers, Kubernetes, and Red Hat OpenShift (DO180) and Red Hat OpenShift Administration I (DO280).

Through an introduction to Docker, Kubernetes, and Red Hat OpenShift Platform, this course helps you understand one of the key tenets of the DevOps movement: continuous integration and continuous deployment. Containers have become a key technology for the configuration and deployment of applications and microservices. Kubernetes is a container orchestration platform that provides foundational services in Red Hat OpenShift Container Platform, which allows enterprises to manage container deployments and scale their applications using Kubernetes.

In addition to gaining an understanding of these tools, you will build core administration skills through the installation, configuration, and management of an OpenShift cluster.
