IaC Using Terraform and GitHub Integration — Lesson 2: State, Modules, Environments, and Secure Design

Learning Objectives

• Manage local and remote state, locking, drift, imports, and lifecycle behavior
• Build reusable modules and organize environments without unsafe duplication
• Handle credentials, secrets, identity, networking, policy, and security requirements

Detailed Topics

• Manage local and remote state: Manage local and remote state, locking, drift, imports, and lifecycle behavior
• Build reusable modules and organize environments without unsafe duplication: Build reusable modules and organize environments without unsafe duplication
• Handle credentials: Handle credentials, secrets, identity, networking, policy, and security requirements

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Refactor a configuration into a reusable module with remote-state and security controls.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, permissions, data, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, support ownership, and user or business impact.

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply State, Modules, Environments, and Secure Design in a realistic scenario and validate the result with documented evidence.
