Oracle Cloud Infrastructure DevOps Professional: Hands-On Workshop — Lesson 3: Resource Manager, Terraform, Policies, Secrets, and Platform Automation

Learning Objectives

• Explain the purpose and operating context of Terraform stacks, state, variables, modules, and Resource Manager jobs.
• Apply plan, apply, drift detection, import, and destructive-change review and dynamic groups, policies, Vault secrets, signing, and least privilege in a controlled environment.
• Validate outcomes and troubleshoot risks involving environment creation, reusable modules, controls, and infrastructure evidence.

Detailed Topics

• Terraform stacks, state, variables, modules, and Resource Manager jobs
• plan, apply, drift detection, import, and destructive-change review
• dynamic groups, policies, Vault secrets, signing, and least privilege
• environment creation, reusable modules, controls, and infrastructure evidence

Instructor Demonstration

Demonstrate Terraform stacks, state, variables, modules, and Resource Manager jobs for a regulated application delivered from commit to production with auditable OCI DevOps controls; capture the exact configuration, code, command, transaction, query, dashboard, model, schedule, or report evidence that proves the expected result.

Hands-On Exercise

Complete a controlled Oracle Cloud Infrastructure DevOps Professional: Hands-On Workshop exercise covering plan, apply, drift detection, import, and destructive-change review and dynamic groups, policies, Vault secrets, signing, and least privilege; introduce an exception involving environment creation, reusable modules, controls, and infrastructure evidence, diagnose it from evidence, apply the smallest reversible correction, and rerun acceptance checks.

1. Confirm scope, prerequisites, identities, dependencies, data, risks, and expected outcome.
2. Perform the course-specific configuration, development, administration, analysis, or business-process workflow.
3. Capture commands, settings, records, logs, screenshots, reports, metrics, or test results.
4. Compare the observed result with acceptance criteria and document corrective or preventive action.

Scenario Analysis

• Identify the technical or business decision and the stakeholders affected by it.
• Compare security, performance, reliability, compliance, cost, usability, and support trade-offs.
• Define rollback, recovery, communication, evidence, ownership, and escalation requirements.

Troubleshooting Guidance

Diagnose issues involving Terraform stacks, state, variables, modules, and Resource Manager jobs, plan, apply, drift detection, import, and destructive-change review, dynamic groups, policies, Vault secrets, signing, and least privilege, environment creation, reusable modules, controls, and infrastructure evidence without making an unverified production change. Separate symptoms from causes, gather time-correlated evidence, test a reversible hypothesis, validate the correction, and record recurrence controls.

Validation Checklist

• The requirement, environment, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by product-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, support actions, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Resource Manager, Terraform, Policies, Secrets, and Platform Automation in a realistic Oracle Cloud Infrastructure DevOps Professional: Hands-On Workshop scenario and defend the result with documented evidence.
