GitOps Workflow
How
it works
1. Create a pull request
Open a pull request and Terragrunt Scale automatically runs a plan. Smart change detection identifies the minimum set of infrastructure units affected by your changes to keep the blast radius small.
2. Review the plan
The Terragrunt plan is posted in the pull request comment, with resource summaries and full plan output for each affected infrastructure unit.
3. Merge to apply
Merge the pull request to apply. Changes roll out in dependency order across your units, stacks, and environments, so main always reflects what's deployed.

Pipelines

Deploy

infra changes with confidence

Secure GitOps Workflow
Plans run automatically when you open a pull request, and applies run on merge in your GitHub/GitLab workflows, not on our servers. Plan output and log summaries appear in comments for easy access.
Smart Dependency Management
Updates are applied while respecting the dependency graph (DAG) order so that adds, changes, and destroys all run successfully, even across environments with their own access control rules.
Minimize Your Blast Radius
Pipelines identifies the minimum set of infrastructure units affected by your changes, avoiding unnecessary operations and limiting risk.

* An infrastructure unit is any directory containing a terragrunt.hcl file
Terragrunt makes managing our infrastructure across providers and environments consistent, safe, and easy to understand. And now with Pipelines, things are even easier… We can literally copy and paste infrastructure and spin up new services, providers, and even full environments in minutes instead of hours or days.
