v1.0.0 released · CI passing AWS Terragrunt Personal project · released Nov 2026

Sixteen Terraform modules behind one root config, with Terragrunt running them in order from their dependency graph.

16: Terraform modules and units
1: Root config replacing 16 copies
-40%: Deployment time (production result)

Approach

Modules stay plain Terraform and Terragrunt wraps them. The backend, provider, and common inputs are generated once from live/root.hcl. _envcommon holds module sources and dependencies, and each unit states only its inputs. dependency blocks build the graph, and mock_outputs let the whole stack validate without a cloud account.
