Terraform File Structure & HCL Syntax Explained | Terraform for Developers
In EP02 of Terraform for Developers, we open up a real Terraform project and walk through every file — what it does, what goes in it, and why it's structured that way. We also cover HCL (HashiCorp Configuration Language) syntax from scratch: blocks, labels, arguments, and expressions.
✅ What you'll learn:
• The 7 files in our Terraform project and what each one does
• HCL syntax: blocks, labels, arguments, and type expressions
• How terraform.tf declares version constraints and required providers
• How providers.tf configures the AWS provider with default tags
• How variables.tf defines typed, documented inputs
• How main.tf uses resource blocks and references other resources
• How outputs.tf and data.tf complete the picture
📌 Based on a real project: a Lambda function with IAM, CloudWatch Logs, and an S3 remote state backend.
