Course description

Create, configure, manage, and troubleshoot OpenShift clusters

Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster with exam (DO281) teaches you how to install and administer the Red Hat® OpenShift® Container Platform. This hands-on, lab-based course shows you how to install, configure, and manage OpenShift clusters and deploy sample applications to further understand how developers will use the platform.

This course is based on Red Hat Enterprise Linux® 8.0 and Openshift Container Platform 4.5. The Red Hat Certified Specialist in OpenShift Administration exam (EX280) is included.

OpenShift is a containerized application platform that allows enterprises to manage container deployments and scale their applications using Kubernetes. OpenShift 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).

Impact on the organization

This course is intended to develop the skills needed to install, configure, and manage the Red Hat OpenShift Container Platform to deploy containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift Container Platform enables rapid application development and deployment, as well as portability of an application across environments. The platform 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 of this training

After completing this course, you should be able to demonstrate the skills to establish a new OpenShift cluster, perform initial configuration of the cluster, and manage the cluster on a day-to-day basis. One major focus of the course is troubleshooting common problems that will be encountered beyond day one.

You should be able to demonstrate these skills:

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