Course description

Create and manage virtual machines on OpenShift by using the Red Hat OpenShift Virtualization operator.

Red Hat OpenShift Virtualization Administration Rapid Track course features the Red Hat OpenShift Virtualization operator for those who already have experience with Red Hat OpenShift administration. This accelerated course combines essential content from Red Hat OpenShift Virtualization Administration I (DO156) and Red Hat OpenShift Virtualization Administration II (DO256) to teach students the skills required to create and manage production-ready virtual machines and their supporting Kubernetes and OpenShift resources in Red Hat OpenShift Virtualization.  

This course is based on Red Hat OpenShift Virtualization 4.18.

Course content summary

• Deploy the OpenShift Virtualization operator and examine the configuration options for the operator.
• Create, manage, and monitor virtual machines in Red Hat OpenShift Virtualization.
• Use comprehensive and flexible networking for virtual machines within an OpenShift environment.
• Configure and manage persistent storage for virtual machines, protect VM data through snapshots, export and import virtual machine images, and efficiently create virtual machine golden images by using cloning within a Red Hat OpenShift Virtualization environment.
• Understand OpenShift OAuth server concepts and custom resources, including their function in Kubernetes authentication, and define and implement role-based access controls and user permissions.
• Enable comprehensive and flexible networking for nodes and virtual machines within an OpenShift environment.
• Migrate virtual machines from another hypervisor to Red Hat OpenShift Virtualization by using the migration toolkit for virtualization (MTV) operator.
• Back up and restore virtual machines by using the OpenShift APIs for Data Protection (OADP) operator.
• Create and manage custom instance types, templates, and boot sources to provision virtual machines.
• Control the placement of virtual machines on cluster nodes by using Kubernetes resources, and rebalance virtual machine workloads across cluster nodes by enabling descheduler evictions.
• Implement high-availability virtual machines that are resilient to failures, planned maintenance, and cluster upgrades by configuring Kubernetes resources.

Target Audience 

• Virtual Machine Administrators who are looking to migrate workloads from traditional hypervisors to OpenShift Virtualization.
• Platform Engineers, Cloud Administrators, and System Administrators who are interested in supporting virtualized workloads, either independently from or in the same OpenShift cluster as containerized workloads.

Prerequisites for this course

• Take our free assessment to gauge whether this offering is the best fit for your skills.
• Red Hat OpenShift Administration I: Operating a Production Cluster (DO180) or equivalent skills in deploying and managing Kubernetes applications by using the OpenShift web console and command-line interfaces is required because of the accelerated pace of this course.
• Red Hat System Administration I (RH124) or equivalent skills in managing Linux systems and servers from the Bash shell is recommended. Although Linux skills are not required for managing OpenShift clusters and OpenShift Virtualization, operating individual Linux VMs requires Linux system administrator skills.

• Configuring High Availability for Virtual Machines in Red Hat OpenShift Virtualization
  Implement high-availability virtual machines that are resilient to failures, planned maintenance, and cluster upgrades by configuring Kubernetes resources.

Impact on the organization

• OpenShift Virtualization enables organizations to realize operational savings by managing virtualized workloads and containerized workloads together by using the same orchestration and clustering infrastructure provided by Red Hat OpenShift.

Impact on the individual

• IT professionals will learn to deploy and manage production-ready virtualized workloads on OpenShift.

Recommended next exam or course

• Red Hat Certified Specialist in OpenShift Virtualization (EX316)
• VM Administrators for OpenShift Virtualization require deeper Kubernetes and OpenShift skills than DO316 provides, even if these individuals will not manage containerized, cloud-native applications, and these skills are provided by existing OpenShift Administration courses:
  • Red Hat OpenShift Administration II: Configuring a Production Cluster (DO280) is also a recommended follow-up course for security and resource management of OpenShift projects.
  • Red Hat OpenShift Administration III: Scaling Deployments in the Enterprise (DO380) and Enterprise Kubernetes Storage with Red Hat OpenShift Data Foundation (DO370) are recommended follow-up courses for node, storage, and security management of OpenShift clusters.
  • Red Hat OpenShift Installation Lab (DO322) is a recommended follow-up course for installing and configuring OpenShift clusters.

Automate and Manage Red Hat OpenShift Virtualization with Ansible (DO336) for using Red Hat Ansible Automation Platform to automate the migration and management of virtual machines in Red Hat OpenShift Virtualization.
