Red Hat OpenShift I: Containers & Kubernetes (DO180)
Overview
Deploy, manage, and troubleshoot containerized applications that run as Kubernetes workloads in OpenShift clusters.
Red Hat OpenShift Administration I: Operating a Production Cluster (DO180) prepares OpenShift cluster administrators to manage Kubernetes workloads and to 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 that represent most cloud-native and containerized workloads. Managing applications also includes deploying and updating their dependencies, such as databases, messaging, and authentication systems.
The skills that you learn in this course apply to 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 4.14.

Why You Should Take This Course
Course content summary:
- Understand container and OpenShift architecture.
- Create containerized services.
- Manage containers and container images.
- Create custom container images.
- Deploy containerized applications on Red Hat OpenShift.
- Deploy multi-container applications.
Impact on the Organization
Containers and Red Hat OpenShift have quickly become the de facto solution for agile development and application deployment. Administrators and developers are increasingly seeking ways to improve application time to market and improve maintainability.
This course provides the gateway to organizational and digital transformation by providing an understanding of the potential of DevOps using a container-based architecture. Orchestrating a container-based architecture with Kubernetes and Red Hat OpenShift improves application reliability and scalability; decreases developer overhead; and facilitates continuous integration and continuous deployment.
This course is the starting point for our Red Hat OpenShift curriculum, establishing the foundation needed to advance to Red Hat OpenShift development or administration.
