A Terragrunt-based Terraform boilerplate for structuring GCP infrastructure with hierarchical configs and isolated state.
- for
- CTOs, DevOps leads, platform engineers building GCP projects
- pricing
- open source
- license
- MIT
Key features
- Hierarchical configuration — Organizes live config and modules in a folder hierarchy that cascades settings.
- State separation per folder — Stores Terraform state in distinct bucket paths to limit blast radius of changes.
- Reusable module layer — Provides a shared repository for common GCP building blocks like VPCs and IAM.
- Explicit Terragrunt dependencies — Declares apply order and cross-stack contracts to avoid accidental ordering issues.
- Environment wiring — Keeps development, staging, and production settings separate and reviewable.
- Promotion paths — Allows pinning module versions per environment for controlled roll-outs.
Use cases
- Create a new GCP project with a clean, repeatable Terragrunt layout
- Manage multi-region, multi-environment infrastructure with isolated state
- Promote changes from dev to staging to prod using version-pinned modules
- Audit and review GCP resources across environments via a single live repo

- GCP Terragrunt Boilerplate vs Pulumi: Infrastructure as code using programming languages instead of HCL/Terragrunt
- GCP Terragrunt Boilerplate vs OpenTofu: Open-source Terraform fork lacking Terragrunt orchestration features
- GCP Terragrunt Boilerplate vs tenv: Manages versions of Terraform/Terragrunt but not a boilerplate structure
