Via CLI flag

Support for skipping all dependency output resolution during a run.

optional-dependency-outputs - What it does

When enabled, users can pass --no-dependency-outputs to skip all dependency output resolution globally. dependency blocks will not call tofu/terraform output, mirroring the existing skip_outputs = true attribute on individual dependency blocks.

terragrunt run --experiment optional-dependency-outputs --no-dependency-outputs -- init

This is useful when you want to run commands that do not need dependency outputs (such as init or validate) without paying the cost of resolving them, or when the dependencies have not been applied yet.

optional-dependency-outputs - How to enable it

# Via CLI flag
terragrunt --experiment optional-dependency-outputs run --no-dependency-outputs -- init

# Via environment variable
export TG_EXPERIMENT=optional-dependency-outputs
terragrunt run --no-dependency-outputs -- init

optional-dependency-outputs - Criteria for stabilization

To transition the optional-dependency-outputs feature to a stable release, the following must be addressed, at a minimum:

• Validate behavior with single-unit and queue-based runs.
• Gather community feedback on the flag name and scope.
• Confirm the interaction with commands that require dependency outputs (such as plan, apply, or destroy).
