DO180: Red Hat OpenShift Administration I: Operating a Production Cluster

Overview

Red Hat OpenShift Administration I: Operating a Production Cluster (DO180) prepares OpenShift cluster administrators to manage Kubernetes workloads and to collaborate with developers, DevOps engineers, system administrators, and SREs to ensure the availability of application workloads. This course focuses on managing typical end-user applications that are often accessible from a web or mobile UI and that represent most cloud-native and containerized workloads. Managing applications also includes deploying and updating their dependencies, such as databases, messaging, and authentication systems.

The skills that you learn in this course apply to all versions of OpenShift, including Red Hat OpenShift on AWS (ROSA), Azure Red Hat OpenShift, and OpenShift Container Platform.

This course is based on Red Hat OpenShift 4.14

Course content summary

  • Managing OpenShift clusters from the command-line interface and from the web console
  • Deploying applications on OpenShift from container images, templates, and Kubernetes manifests
  • Troubleshooting network connectivity between applications inside and outside an OpenShift cluster
  • Connecting Kubernetes workloads to storage for application data
  • Configuring Kubernetes workloads for high availability and reliability
  • Managing updates to container images, settings, and Kubernetes manifests of an application

Pre-Requisites

The participant must be able to use Linux terminal session and issue operating system commands. They have to be a Red Hat Certified System Administrator (RHCSA) or possess experience equivalent to RHCSA. In addition, they may preferably have experience with web application architectures and their corresponding technologies.
