Course Overview
Installing OpenShift on a cloud, virtual, or physical infrastructure.
Red Hat OpenShift Installation Lab (DO322) teaches essential skills for installing an OpenShift cluster in a range of environments, from proof of concept to production, and how to identify customizations that may be required because of the underlying cloud, virtual, or physical infrastructure.
This course is based on Red Hat OpenShift Container Platform 4.6.
Who should attend
- Cluster administrators (Junior systems administrators, junior cloud administrators) interested in deploying additional clusters to meet increasing demands from their organizations.
- Cluster engineers (Senior systems administrators, senior cloud administrators, cloud engineers) interested in the planning and design of OpenShift clusters to meet performance and reliability of different workloads and in creating work books for these installations.
- Site reliability engineers (SREs) interested in deploying test bed clusters to validate new settings, updates, customizations, operational procedures, and responses to incidents.
Prerequisites
- Achieving the Red Hat Certified Specialist in OpenShift Administration certification on OpenShift 4 is strongly recommended, or at least taking Red Hat OpenShift Administration II: Configuring a Production Cluster (DO280) before taking this course.
- “Equivalent knowledge of Kubernetes” is not applicable here because performing anything other than a very minimal, all-defaults Full Stack Automated installation of OpenShift on a cloud provider requires knowledge of OpenShift cluster operators.
- Achieving the Red Hat Certified System Administrator (RHCSA) certification or equivalent knowledge of Red Hat Enterprise Linux system administration before taking DO322 is also strongly recommended.
Course Objectives
Impact on the organization
This course supports IT Operations teams whose organizations are either starting or expanding their Container Adoption Journeys. Proper planning and execution of installation steps help to ensure successful production environments that are more stable, secure, and reliable.
Impact on the individual
This course teaches skills required to plan and provision OpenShift clusters on cloud providers and on-site data centers, using virtual machines and physical servers, such as:
Assessing whether to employ the Full Stack Automation or Pre-existing Infrastructure installation methods. Customizing the OpenShift installation settings to match a target deployment scenario. Monitoring the OpenShift installation process to identify and, if possible, fix issues. Assessing the health of a just-installed OpenShift cluster, and assessing the need to perform additional tasks before on-boarding users and applications.
