OpenTofu features
- Exclusion Flag. Use -exclude to selectively skip resources during plan and apply operations.
- Provider Iteration. Dynamically generate providers with for_each for multi-region, multi-environment deployments.
- Early Variable/Local Evaluation. Update modules globally via a single variable change for consistent versioning.
- State Encryption. Client-side encryption of state files with multiple key providers (PBKDF2, AWS KMS, GCP KMS, OpenBao).
- Community-Driven Development. Open source project governed by the Linux Foundation with contributions from many vendors.
GCP Terragrunt Boilerplate 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.
