DO121
Introduction to Microsoft Azure Red Hat OpenShift (ARO)
Overview
Course description
Learn how to deploy, access, and perform basic customizations to an ARO cluster.
DO121 teaches Platform Operators how to provision managed clusters by using Microsoft Azure Red Hat OpenShift (ARO) and how to perform basic day-2 customizations on these clusters to onboard application developers and applications.
Course content summary
- Introduction to Managed OpenShift
- Identify prerequisites to create an ARO cluster
- Deploy an ARO cluster
- Access an ARO cluster as an administrator
- Configure an ARO cluster for developer self-service
- Connect an ARO cluster to Red Hat Services
Audience for this course
- IT Operations professionals such as System Administrators, Platform Operators, Cloud Engineers.
- Application and development infrastructure professionals such as Site Reliability Engineers and DevOps Engineers.
Recommended training
- All students must be knowledgeable of Microsoft Azure, including operating and managing Azure compute, storage, and network resources.
- For students that are new to Red Hat OpenShift it is recommended that you learn the fundamental skills of managing Red Hat OpenShift clusters, before taking DO121, from the following courses:
- Students with previous experience managing Kubernetes clusters are advised to take DO180 and DO280 before taking DO121 or at least acquire foundational skills operating Red Hat OpenShift clusters by using the following free resources from Red Hat:
Technology considerations
- Internet access is required to access Azure cloud services using the Azure Portal and the Azure CLI. It is also required to access the Red Hat Hybrid Cloud Console and associated Red Hat cloud services.
- Students must possess an active Azure account with an associated payment method for the Azure resources consumed by ARO clusters.
- Students must possess an active Red Hat customer portal account or a free Red Hat Developer program membership.
Outline
Outline for this course
Provision a Managed Azure Red Hat OpenShift (ARO) Cluster
Create a Microsoft Azure Red Hat OpenShift (ARO) cluster accessible through the internet.
- Introduction to Managed OpenShift Clusters
- Describe the relationship between the customer team and the cloud vendors SRE team regarding system administration of managed OpenShift clusters.
- Prerequisites to Create an ARO Cluster

- Create an ARO Cluster
- Create an internet-accessible managed OpenShift cluster using the Azure portal and inspect the cloud resources that compose an ARO cluster.
- Access an ARO Cluster as an Administrator
- Retrieve OpenShift cluster administrator credentials to access a managed cluster.
Configure a Managed Azure Red Hat OpenShift (ARO) Cluster
Configure a Microsoft Azure Red Hat OpenShift (ARO) cluster to be used for development purposes.
- Configure Developer Self-service Access to an ARO Cluster
- Configure an identity provider that allows developers to access a managed cluster and create self-service projects to deploy unprivileged applications.
- Connect an ARO cluster to Red Hat cloud services
- Connect a managed cluster to Red Hat cloud services and enumerate the benefits.
Outcomes
Impact on the organization
Microsoft Azure Red Hat® OpenShift® is a turnkey application platform that provides highly available, fully managed Red Hat OpenShift clusters on demand. Red Hat and Microsoft jointly engineer, manage, and support the platform, allowing organizations to increase operational efficiency, refocus on innovation, and quickly build, deploy and scale applications.
Red Hat OpenShift is the hybrid cloud platform that brings operational consistency to on-premises and cloud environments. Organizations using ARO follow the same operational processes used by a self-managed Red Hat OpenShift Container Platform on their on premises data centers and deploy the same applications on any OpenShift cluster, be it a managed cluster or a self-managed one.
Impact of this training
After completing DO121, system administrators can create internet-accessible ARO clusters, under their organization cloud account, which supports proof-of-concept and development environments.
The majority of day-to-day application and cluster administration tasks are performed the same way for ARO managed clusters and self-managed Red Hat OpenShift Container Platform (RHOCP) clusters so IT professionals apply the same skills managing Red Hat OpenShift clusters to on premises and cloud environments.
Recommended next exam or course
Students are recommended to take the following courses before enrolling on DO121:
- Red Hat OpenShift I: Containers & Kubernetes (DO180)
- Red Hat OpenShift II: Operating a Production Kubernetes Cluster (DO280)
After completing DO121, students can proceed to additional operations and development training on Red Hat OpenShift, such as:
