Deploy, manage, and troubleshoot containerized applications running as Kubernetes workloads in OpenShift clusters.

Utbildningsmål

Red Hat OpenShift Administration I: Managing Containers and Kubernetes (DO180) prepares OpenShift Cluster Administrators to perform day-to-day management of Kubernetes workloads and collaborate with Developers, DevOps Engineers, System Administrators, and SREs to ensure the availability of application workloads.
This course focuses on managing typical end-user applications that are often accessible from a web or mobile UI and represent the majority of cloud native and containerized workloads. Management of applications also includes deployment and updating of their dependencies such as databases, messaging, and authentication systems.
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 Red Hat® OpenShift® 4.12.

• Managing OpenShift clusters from the command-line interface and from the web console.
• Troubleshooting network connectivity between applications inside and outside of an OpenShift cluster.
• Connecting Kubernetes workloads to storage for application data.
• Configuring Kubernetes workloads for high availability and reliability.
• Managing updates to container images, settings, and Kubernetes manifests of an application.
