DO280 Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster

Opis

Create, configure, manage, and troubleshoot OpenShift clusters

DO280 Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster 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.

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).

Course summary

• Describe the Red Hat OpenShift Container Platform cluster installation and update processes

• Troubleshoot application deployments

• Configure authentication using local users

• Control access to projects using role-based access control (RBAC)

• Configure service and container networking

• Configure pod scheduling using labels and selectors

• Limit compute resource usage

• Scale a cluster

• Monitor cluster events and alerts

Cel

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.

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.
