Terragrunt
Adopt
What
Terragrunt is a thin wrapper around OpenTofu that keeps infrastructure-as-code DRY across environments. It's the standard way we manage AWS resources.
Why this ring
It's our established standard for infrastructure as code - it gives us a consistent way to manage AWS resources across environments without duplicating configuration, on top of OpenTofu.
What does this mean
Manage infrastructure through Terragrunt (wrapping OpenTofu). New infrastructure work should follow the existing Terragrunt structure across environments.
