Red Hat OpenShift Administration II (DO380) expands upon the skills required to plan, implement, and manage OpenShift® clusters in the enterprise. You will learn how to support a growing number of stakeholders, applications, and users to achieve large-scale deployments.
- Manage OpenShift cluster operators and add operators
- Automate OpenShift management tasks using Ansible® playbooks
- Create and schedule cluster administration jobs
- Implement GitOps workflows using Jenkins
- Integrate OpenShift with enterprise authentication
- Query and visualize cluster-wide logs, metrics, and alerts
- Manage both shared, file-based storage and non-shared, block-based storage
- Manage machine sets and machine configurations
Audience for this course
- Cluster engineers (systems administrators, cloud administrators, or cloud engineers) focused on planning, designing, and implementing production-grade OpenShift clusters. Cluster engineers require automation skills to scale their manpower to provision and manage an increasing population of clusters, applications, and users, at the same time ensuring these clusters remain in compliance with corporate standards.
- Site reliability engineers (SREs) focused on keeping OpenShift clusters and applications running without disruption. SREs are interested in troubleshooting infrastructure and application issues with OpenShift clusters and require automation skills to reduce the time to identify, diagnose, and remediate issues.
Red Hat recommends these prerequisites:

Configure enterprise authentication
- Implement a GitOps workflow using containerized Jenkins to administer an OpenShift cluster.
Configure trusted TLS certificates
- Integrate OpenShift with enterprise identity providers.
Configure dedicated node pools
- Configure OpenShift with trusted TLS certificates for external access to cluster services and applications.
Configure persistent storage
- Add nodes to an OpenShift cluster with custom configurations tuned for special workloads.
Manage cluster monitoring and metrics
- Configure storage providers and storage classes to ensure cluster user access to persistent storage.
Provision and inspect cluster logging
- Configure and manage the OpenShift monitoring stack.
Recover failed worker nodes
- Deploy, query, and troubleshoot cluster-wide logging.
