[puneeth-grinds]

What

Set up the foundation for Terraform learning by configuring a reproducible development environment, initializing the Terraform project structure, and completing the first end-to-end Terraform workflow.

Changes

• Added a GitHub Codespaces dev container for Terraform development
• Installed Terraform and AWS CLI through Dev Container Features
• Configured the initial Terraform project structure
• Added:
  • versions.tf
  • providers.tf
  • main.tf
• Configured the AWS provider
• Added a Terraform .gitignore
• Initialized the Terraform working directory (terraform init)
• Generated and committed .terraform.lock.hcl
• Successfully validated the Terraform configuration
• Created the first AWS S3 bucket using Terraform
• Verified infrastructure creation with terraform apply
• Destroyed the infrastructure using terraform destroy
• Verified the complete Terraform lifecycle from configuration to cleanup

Concepts Covered

• Infrastructure as Code (IaC)
• Declarative vs Imperative Infrastructure
• Providers and Resources
• Desired State
• Terraform State (terraform.tfstate)
• Terraform Workflow
• terraform fmt
• terraform validate
• terraform init
• terraform plan
• terraform apply
• terraform destroy
• .terraform directory
• .terraform.lock.hcl
• Terraform project structure and Git best practices

Outcome

Established a production-style Terraform development environment and successfully completed the first end-to-end infrastructure deployment lifecycle on AWS.
