Red Hat OpenShift Administration III: Scaling Deployments in the Enterprise
Plan, implement, and manage OpenShift clusters at scale
Red Hat OpenShift Administration III: Scaling Kubernetes Deployments in the Enterprise (DO380) expands upon the skills required to plan, implement, and manage OpenShift® clusters in the enterprise. You will learn how to configure and manage OpenShift clusters at scale to address increasing and special demands from applications and ensure reliability, performance, and availability.
This course builds upon the essential skills required to configure and manage an OpenShift 4.x cluster, teaching the enhanced skills needed to operate production environments at scale.
Authentication and Identity Management
- Configure OpenShift clusters to authenticate by using LDAP and OIDC enterprise identity systems and to recognize groups that those systems define.
Backup, Restore, and Migration of Applications with OADP
- Backup and restore application settings and data with OpenShift APIs for Data Protection (OADP).
Cluster Partitioning
- Configure a subset of cluster nodes to be dedicated to a type of workload.
Pod Scheduling
- Configure workloads to run on a dedicated set of cluster nodes and prevent other workloads from using those cluster nodes.
OpenShift GitOps
- Deploy OpenShift GitOps for managing clusters and applications.
OpenShift Monitoring
- Troubleshoot performance and availability issues with applications and clusters.
OpenShift Logging
- Deploy OpenShift logging and query log entries from workloads and cluster nodes.
