DO007 – Ansible Basics: Automation Technical Overview — Lesson 3: Roles, Collections, Automation Platform, Controller, Hub, and Execution Environments

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing roles and collections.
• Implement and validate automation controller, private automation hub, and execution environments using reviewable evidence.
• Evaluate the condition where operators cannot explain the outcome because logs, commands, settings, and acceptance evidence were not captured consistently and select a proportionate corrective response.

Detailed Topics

• roles applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• collections applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• automation controller applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• private automation hub applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• execution environments applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces an IT leadership and engineering group evaluating Ansible for a standardized enterprise automation program. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the Ansible adoption brief, prioritized use-case register, governance outline, and implementation roadmap. It also tests the exception where operators cannot explain the outcome because logs, commands, settings, and acceptance evidence were not captured consistently.

Hands-On Exercise

Complete a controlled Red Hat exercise covering Roles, Collections, Automation Platform, Controller, Hub, and Execution Environments and preserve the verified result in the Ansible adoption brief, prioritized use-case register, governance outline, and implementation roadmap.

1. Confirm scope, prerequisites, versions, identities, dependencies, and acceptance criteria.
2. Execute the workflow while recording commands, settings, outputs, events, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, rollback, and handover actions.

Scenario Analysis

• Identify which object, service, policy, setting, or sequence most strongly influences roles.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the Ansible adoption brief, prioritized use-case register, governance outline, and implementation roadmap should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected behavior first differs from the observed result. Check prerequisites, identity, configuration order, version compatibility, connectivity, status, resource limits, and evidence separately. Treat “operators cannot explain the outcome because logs, commands, settings, and acceptance evidence were not captured consistently” as a hypothesis until commands, logs, settings, and retest outcomes confirm the cause.

Validation Checklist

• Required platform components, identities, permissions, settings, and dependencies are present.
• The Ansible adoption brief, prioritized use-case register, governance outline, and implementation roadmap connects each conclusion to objective, reviewable evidence.
• Normal processing, a boundary condition, dependency behavior, and the stated exception were tested.
• Corrections, ownership, retest criteria, rollback, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Roles, Collections, Automation Platform, Controller, Hub, and Execution Environments, explain the resulting platform behavior, and defend the outcome through the Ansible adoption brief, prioritized use-case register, governance outline, and implementation roadmap.
