DO080 – Containers, Kubernetes and Red Hat OpenShift Technical Overview — Lesson 3: OpenShift Platform, Builds, Routes, Security, Storage, and Operations

Learning Objectives

• Evaluate security, resilience, integration, and exception handling for OpenShift architecture, builds, and routes.
• Apply security and storage and operations while preserving reviewable technical evidence.
• Recognize and correct the risk where the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay.

Detailed Topics

• OpenShift architecture: apply the concept to a technology group assessing containers and OpenShift for application modernization, record the relevant settings or decisions, and explain the operational consequence.
• builds: apply the concept to a technology group assessing containers and OpenShift for application modernization, record the relevant settings or decisions, and explain the operational consequence.
• routes: apply the concept to a technology group assessing containers and OpenShift for application modernization, record the relevant settings or decisions, and explain the operational consequence.
• security: apply the concept to a technology group assessing containers and OpenShift for application modernization, record the relevant settings or decisions, and explain the operational consequence.
• storage and operations: apply the concept to a technology group assessing containers and OpenShift for application modernization, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates openshift platform, builds, routes, security, storage, and operations by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Introduce a controlled boundary condition and test recovery for OpenShift Platform, Builds, Routes, Security, Storage, and Operations. Add verified outcomes to the container platform assessment, workload suitability matrix, adoption risks, and next-step roadmap.

1. Confirm the scope, versions, access, dependencies, and success criteria.
2. Perform the workflow while recording commands, settings, output, and platform events.
3. Test one expected case and one controlled exception specific to this lesson.
4. Retest the correction and document ownership, rollback, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences OpenShift architecture in the stated scenario.
• Compare two approaches for security and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the container platform assessment, workload suitability matrix, adoption risks, and next-step roadmap before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check security, integration, boundary conditions, and resilience separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay; confirm the cause with a reproducible retest.

Validation Checklist

• The required security, integration, boundary conditions, and resilience were checked and recorded.
• The normal path and a course-specific exception were tested.
• The container platform assessment, workload suitability matrix, adoption risks, and next-step roadmap links conclusions to commands, configuration, logs, or other objective evidence.
• Corrective actions, rollback steps, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply OpenShift Platform, Builds, Routes, Security, Storage, and Operations, explain the observed Red Hat platform behavior, and support the result with a reviewable container platform assessment, workload suitability matrix, adoption risks, and next-step roadmap.
