CS229 Deploying Production AWS ROSA Clusters: Creation, Configuration, and Application Integration — Lesson 2: Cluster Creation, Installer Options, Identity Providers, Access, and Security

Learning Objectives

• Configure the main services, objects, and controls involved in cluster creation, installer options, and identity providers.
• Apply administrative access and security while preserving reviewable technical evidence.
• Recognize and correct the risk where a valid command creates the wrong outcome because variables, identity, or sequencing are incorrect.

Detailed Topics

• cluster creation: apply the concept to a cloud platform team deploying a production ROSA cluster and onboarding a business application, record the relevant settings or decisions, and explain the operational consequence.
• installer options: apply the concept to a cloud platform team deploying a production ROSA cluster and onboarding a business application, record the relevant settings or decisions, and explain the operational consequence.
• identity providers: apply the concept to a cloud platform team deploying a production ROSA cluster and onboarding a business application, record the relevant settings or decisions, and explain the operational consequence.
• administrative access: apply the concept to a cloud platform team deploying a production ROSA cluster and onboarding a business application, record the relevant settings or decisions, and explain the operational consequence.
• security: apply the concept to a cloud platform team deploying a production ROSA cluster and onboarding a business application, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates cluster creation, installer options, identity providers, access, and security by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how a valid command creates the wrong outcome because variables, identity, or sequencing are incorrect and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Implement the core workflow and compare expected versus observed behavior for Cluster Creation, Installer Options, Identity Providers, Access, and Security. Add verified outcomes to the ROSA production design, cluster deployment evidence, application integration record, and operations runbook.

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 cluster creation in the stated scenario.
• Compare two approaches for administrative access and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the ROSA production design, cluster deployment evidence, application integration record, and operations runbook before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check configuration, permissions, sequencing, and functional behavior separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that a valid command creates the wrong outcome because variables, identity, or sequencing are incorrect; confirm the cause with a reproducible retest.

Validation Checklist

• The required configuration, permissions, sequencing, and functional behavior were checked and recorded.
• The normal path and a course-specific exception were tested.
• The ROSA production design, cluster deployment evidence, application integration record, and operations runbook 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 Cluster Creation, Installer Options, Identity Providers, Access, and Security, explain the observed Red Hat platform behavior, and support the result with a reviewable ROSA production design, cluster deployment evidence, application integration record, and operations runbook.
