About Terragrunt

Terragrunt is a flexible orchestration tool for Infrastructure as Code written in OpenTofu or Terraform. It helps platform teams organize and speed up their IaC by breaking down monolithic infrastructure into manageable units with independent state. The tool provides control over what infrastructure is updated, how it gets updated, and in what order using a Run Queue.

Key features

Segment infrastructure into manageable units with independent state
Control updates with a Run Queue to reject all-or-nothing updates
Authentication tooling for managing infrastructure across environments and cloud providers with least privilege access
Automate tasks before and after IaC updates using hooks
Handle expected errors from flaky networks and cloud providers with built-in error handling
Catalog standard infrastructure patterns for reuse using a Terminal User Interface (TUI)

Good fit for

Standardize Infrastructure as Code across an organization
Manage growing infrastructure complexity with units and stacks
Execute modules in dependency order across environments
