Is This The Right Course?

  • Complete Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster(DO280) and become a Red Hat Certified Specialist in OpenShift Administration.
  • Complete Red Hat System Administration II (RH134) and become a Red Hat Certified System Administrator.
  • Recommended, but not required: become a Red Hat Certified Systems Engineer or a Red Hat Certified Specialist in Ansible Automation. Basic knowledge about writing and running Ansible playbooks is required.

Technology requirements

This course requires internet access to access the cloud-based classroom environment that provides an OpenShift cluster and a remote administrator’s workstation.
This course also requires that the classroom environment can access the Red Hat registry, Red Hat Quay, and GitHub.
You are also required to have personal, free accounts at GitHub.

Who Should Attend?

  • 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.
