Explain
Terragrunt is designed to reduce boilerplate Terraform code by enabling reusable modules and configurations.
Supports managing Terraform remote state backends automatically, including locking and versioning.
Facilitates multi-environment setups (dev, staging, production) with shared modules and variables.
Integrates seamlessly with Terraform CLI and modules.
Enables orchestration of Terraform commands across multiple modules in the correct dependency order.
Core Features
Terragrunt.hcl - central configuration file for modules
Include blocks - reusing configurations across modules
Dependencies - define module execution order
Remote state configuration - automatic backend setup
Hooks - pre- and post-Terraform command scripts
Basic Concepts Overview
Terragrunt.hcl - main configuration file
Include blocks - for shared settings and variables
Dependencies - declare inter-module relationships
Remote state - backend configuration for Terraform
Hooks - scripts executed pre- and post-Terraform commands
Project Structure
Live/ - environment-specific configurations (dev, staging, prod)
Modules/ - reusable Terraform modules
terragrunt.hcl - central configuration per module/environment
Hooks/ - optional pre/post scripts
README.md documenting setup and usage
Building Workflow
Organize Terraform modules per service/component
Create terragrunt.hcl for each module/environment
Configure remote state and backend settings
Define dependencies between modules if needed
Run `terragrunt apply` to provision resources
