Learn TERRAGRUNT with Real Code Examples

Terragrunt config files (terragrunt.hcl) reference Terraform modules

Dependencies define module execution order

Hooks run custom scripts before/after Terraform commands

Remote state management configured automatically

CLI orchestrates Terraform commands using Terragrunt configurations

terragrunt.hcl -> module reference -> Terraform plan/apply -> hooks -> outputs
