Terraform Workbook - Your Guide to Infra as Code (IaC)

This post outlines the various Terraform project files and their purposes, such as vars.tf for default variable declarations, terraform.tfvars for overriding default variable values, terraform.tf for tfstate backends and provider declarations, version.tf for Terraform version constraints, and .terraform.lock.hcl for dependency snapshots. Additional files in a Terraform project, like network.tf or database.tf, contain modules or provider resources for managing infrastructure. The post also includes examples of variables, tf files for Azure and Google Cloud, version constraints, and running Terraform commands like init, plan, apply, state manipulation, force-unlock, and taint.
