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

Opis

Configure, manage, and troubleshoot OpenShift clusters and containerized applications

Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280) teaches you how to configure, troubleshoot, and manage Red Hat® OpenShift® Container Platform. This hands-on, lab-based course shows you how to verify the successful installation of a cluster, manage it on a day-to-day basis, and troubleshoot the deployment of containerized applications.

This course is based on Red Hat® Enterprise Linux® 8.2 and OpenShift® Container Platform 4.6.

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 content summary

• Describe the Red Hat OpenShift Container Platform cluster installation and update processes
• Troubleshoot application deployment issues
• Configure authentication using local users
• Control access to projects using groups and role-based access control (RBAC)
• Expose applications to clients external to the cluster using TLS encryption
• Configure network isolation between services and applications using network policies
• Configure application scheduling using labels and selectors
• Limit compute resource usage of applications with resource limits and quotas
• Manage a cluster and deployed applications with the Web Console
• Install Kubernetes Operators with the Web Console

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.
