DO180 Red Hat OpenShift Administration I: Containers & Kubernetes

Opis

Cel

Impact on the Organization

This course is intended to develop the skills needed to manage Red Hat OpenShift clusters and support containerized applications that are highly available, resilient, and scalable. Red Hat OpenShift is an enterprise-hardened application platform based on Kubernetes that provides a common set of APIs and abstractions that  enable application portability across cloud providers and traditional data centers. Red Hat OpenShift adds consistency and portability of operational processes across these environments and can also be deployed as a managed service. An external SRE team shares the responsibility of managing Red Hat OpenShift clusters with a customer’s IT operations team when using a managed OpenShift offering such as Red Hat OpenShift on AWS (ROSA) or Azure Red Hat OpenShift (ARO).

Impact on the Individual

• As a result of attending this course, students will understand the architecture of Red Hat OpenShift clusters and of Kubernetes applications, and will be able to deploy, manage, and troubleshoot applications on OpenShift. Students will also be able to identify and escalate application and infrastructure issues to development teams, operation teams, and IT vendors.

Grupa docelowa

• System Administrators and Platform Operators interested in the ongoing management of OpenShift clusters and containerized applications.
• Site Reliability Engineers interested in the ongoing maintenance and troubleshooting of containerized applications on Kubernetes.
• System and Software Architects interested in understanding the features and functionality of an OpenShift cluster.
