IaC Using Terraform and GitHub Integration — Lesson 1: Infrastructure as Code and Terraform Foundations

Learning Objectives

• Explain infrastructure as code, declarative configuration, providers, resources, and dependency graphs
• Install Terraform, configure providers, initialize projects, and use plan and apply workflows
• Manage variables, outputs, locals, data sources, expressions, and reusable configuration structure

Detailed Topics

• Explain infrastructure as code: Explain infrastructure as code, declarative configuration, providers, resources, and dependency graphs
• Install Terraform: Install Terraform, configure providers, initialize projects, and use plan and apply workflows
• Manage variables: Manage variables, outputs, locals, data sources, expressions, and reusable configuration structure

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

Create a Terraform configuration and validate its plan before controlled deployment.

• 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 Infrastructure as Code and Terraform Foundations in a realistic scenario and validate the result with documented evidence.
