DO280: Red Hat OpenShift Administration II: Configuring a Production Cluster

Overview

Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280) prepares OpenShift Cluster Administrators to perform daily administration tasks on clusters that host applications provided by internal teams and external vendors, enable self-service for cluster users with different roles, and deploy applications that require special permissions such as such as CI/CD tooling, performance monitoring, and security scanners. This course focuses on configuring multi-tenancy and security features of OpenShift as well as managing OpenShift add-ons based on operators.

The skills you learn in this course can be applied using all versions of OpenShift, including Red Hat OpenShift on AWS (ROSA), Azure Red Hat OpenShift (ARO), and OpenShift Container Platform.

This course is based on OpenShift Container Platform 4.14

Summary:

  • Deploying packaged applications using manifests, templates, kustomize, and helm.
  • Configuring authentication and authorization for users and applications.
  • Protecting network traffic with network policies and exposing applications with proper network access.
  • Deploying and managing applications using resources manifests.
  • Enabling developer self-service of application projects.
  • Managing OpenShift cluster updates and Kubernetes operator updates.

Course Outline

Declarative Resource Management
Deploy and update applications from resource manifests that are parameterized for different target environments.

Deploy Packaged Applications
Deploy and update applications from resource manifests that are packaged for sharing and distribution.

Authentication and Authorization
Configure authentication with the HTPasswd identity provider and assign roles to users and groups.

Network Security
Protect network traffic between applications inside and outside the cluster.

Expose non-HTTP/SNI Applications
Expose applications to external access without using an Ingress controller.

Enable Developer Self-Service
