Goals

• Deploy your first infrastructure (e.g., EC2 on AWS or VM on Azure/GCP)

Topics

• Providers and authentication
• Resources and arguments
• Variables and outputs
• State file basics

Lab

• Launch an EC2 instance
• Output its public IP
• Terminate it

Goals

• Make code reusable and modular

Topics

• Input variables (types, defaults, descriptions)
• Output values
• Local values
• Data sources (e.g., fetch latest AMI)

Lab

• Create an EC2 instance using variables
• Fetch latest Amazon Linux AMI with data source
• Output public DNS and IP

Goals

• Manage and secure Terraform state properly.

Topics

• Local vs remote state
• Locking and state management
• Backends: S3, Azure Blob, GCS
• terraform state commands

Lab

• Move local state to S3
• Enable DynamoDB locking (AWS only)

Goals

• Create reusable infrastructure components.

Topics

• Module structure: main.tf, variables.tf, outputs.tf
• Using public modules from Terraform Registry
• Creating and consuming custom modules

Lab

• Build a reusable EC2 module
• Call it multiple times with different inputs

Goal

• Automate advanced cloud setups (VPCs, Load Balancers, etc.)

Topics

• Tainting, targeting, and lifecycle rules
• Count, for_each, dynamic blocks
• Templating with templatefile()
• Provisioners (use with caution)
• Terraform Cloud & Workspaces

Lab

• Deploy a 3-tier architecture (VPC, subnets, EC2, RDS) using modules
• Use for_each to deploy multiple similar resources

Goal

• Integrate Terraform into your pipeline and secure it.

Topics

• Role-based access control (IAM roles for Terraform)
• Secrets handling (Vault, SSM, etc.)
• Terraform in GitHub Actions / GitLab CI / Jenkins
• Pre-commit hooks and linters (tflint, checkov)
• GitOps-style Terraform (Atlantis, Spacelift)
