Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster-DO280
Configure, manage, and troubleshoot OpenShift clusters and containerized applications.
Course 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 4.12.
5-10 Course Topics
- 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.
Target Audience
- System Administrators and Platform Operators interested in the ongoing management of OpenShift clusters, applications, users, and add-ons.
- Site Reliability Engineers interested in the ongoing maintenance and troubleshooting of Kubernetes clusters.
- System and Software Architects interested in understanding the security of an OpenShift cluster.
Recommended Training
- Take our free assessment to gauge whether this offering is the best fit for your skills.
- Prerequisite: Red Hat OpenShift I: Containers & Kubernetes (DO180 v4.12), or equivalent skills deploying and managing Kubernetes applications using the OpenShift web console and command-line interfaces.
Technology considerations
- This course requires internet access to access the cloud-based classroom environment that provides an OpenShift cluster and a remote administrator’s workstation.
Outline for this course:
Deploy and update applications from resource manifests that are parameterized for different target environments.
Deploy and update applications from resource manifests that are packaged for sharing and distribution.
Configure authentication with the HTPasswd identity provider and assign roles to users and groups.
Protect network traffic between applications inside and outside the cluster.
Expose applications to external access without using an Ingress controller.
Configure clusters for safe self-service by developers from multiple teams and disallow self-service if projects have to be provisioned by the operations staff.
Install and update Operators that are managed by the Operator Lifecycle Manager and by the Cluster Version Operator.
Run applications that require elevated or special privileges from the host Operating System or Kubernetes.
- Update an OpenShift cluster and minimize disruption to deployed applications.
