DO285 – Containers, Kubernetes, and Red Hat OpenShift Administration I


One of the key tenets of DevOps is 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. DO285 combines the content from Introduction to Containers, Kubernetes, and Red Hat® OpenShift (DO180) and Red Hat OpenShift Administration I (DO280).

This course is based on Red Hat OpenShift Container Platform 3.5.


Course overview

This course helps you build core knowledge and skills in managing containers through hands-on experience with Docker, Kubernetes, and the Red Hat OpenShift Container Platform. OpenShift Container Platform is a containerized application platform that allows enterprises to manage container deployments and scale their applications using Kubernetes. OpenShift Container Platform provides predefined application environments and builds upon Kubernetes to provide support for DevOps principles such as reduced time to market, infrastructure as code, continuous integration (CI), and continuous delivery (CD). Red Hat OpenShift Administration I (DO285) is a hands-on, lab-based course that teaches system administrators how to install, configure, and manage OpenShift clusters.

Impact of this training

Impact on the organization

This course is intended to expose you to container and container orchestration technologies such as Docker, Kubernetes, and Red Hat OpenShift. You are taught how to containerize software applications and services. Moving applications and services from traditional deployment platforms to container deployments make the applications deployable on a single clustered cloud architecture instead of many disparate sets of hardware configurations. Red Hat OpenShift Container Platform enables rapid application development and deployment, as well as portability of an application across environments. It also offers simplified application scaling, administration, and maintenance of adapted or cloud-native applications.

Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.

Impact on the individual

As a result of attending this course, you should be able to install, configure, and manage a Red Hat OpenShift Container Platform cluster and deploy applications on it.

You should be able to demonstrate these skills:

  • Install OpenShift Container Platform to create a simple cluster.
  • Configure and manage OpenShift Container Platform masters and nodes.
  • Secure OpenShift Container Platform with a simple internal authentication mechanism.
  • Control access to resources on OpenShift Container Platform.
  • Deploy applications on OpenShift Container Platform using source-to-image (S2I).
  • Configure and manage OpenShift Container Platform pods, services, routes, secrets, and other resources.
