Scale Terraform and OpenTofu workflows with flexible orchestration
Terragrunt extends Terraform/OpenTofu, providing reusable configurations, dependency management, and environment handling to simplify large‑scale infrastructure automation across multiple clouds and teams.
Terragrunt is aimed at DevOps engineers, platform teams, and developers who manage complex Terraform/OpenTofu codebases across multiple environments or clouds. It helps teams enforce DRY principles, reduce duplication, and maintain a clear dependency order when provisioning resources.
Terragrunt wraps Terraform/OpenTofu commands, adding a lightweight configuration layer written in HCL. It automatically sources remote state backends, injects environment‑specific variables, and builds a dependency graph so modules run in the correct sequence. The tool can be installed via a single binary and integrated into CI/CD pipelines, local development shells, or containerized workflows.
By storing common settings in a terragrunt.hcl hierarchy, organizations can version‑control infrastructure once and apply it consistently across staging, production, and feature environments. Terragrunt’s built‑in locking prevents concurrent state corruption, and its modular approach simplifies onboarding new team members while keeping the underlying Terraform code untouched.
When teams consider Terragrunt, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Standardize environments across dev, staging, prod
Deploy identical infrastructure with environment‑specific variables using a shared terragrunt.hcl hierarchy.
Orchestrate dependent services
Automatically apply database module before application servers, ensuring correct creation order.
Integrate with CI/CD
Run terragrunt plan/apply in pipelines, leveraging built‑in state locking to avoid race conditions.
Migrate legacy Terraform code
Wrap existing modules with terragrunt to introduce DRY configs without rewriting resources.
No, Terragrunt works as a thin wrapper and can be pointed at existing .tf files.
It can generate backend blocks automatically and supports locking via supported backends like S3 with DynamoDB.
Yes, Terragrunt operates on any Terraform‑compatible CLI, including OpenTofu.
The binary can be added to any container image, and commands run the same as locally.
Gruntwork offers paid support plans listed on the Terragrunt website.
