Red Hat OpenShift Administration III: Scaling Deployments in the Enterprise

Course description

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 support a growing number of stakeholders, applications, and users to achieve large-scale deployments.

This course is based on Red Hat® OpenShift Container Platform 4.10.

Following course completion, you will receive a 45-day extended access to hands-on labs for any course that includes a virtual environment.

Note: This course is offered as a five day virtual class or self-paced. Durations may vary based on the delivery. For full course details, scheduling, and pricing, select your location then “get started” on the right hand menu.

Course summary
  • 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 pools 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.
Prerequisites for this course
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.
