RFC Template

This is a template you can use for proposing new major features to Terragrunt. When creating a new RFC, copy this template and fill in each respective section.

STATUS: In proposal (This should be updated when you open a PR for the implementation)

Background

This section should describe why you need this feature in Terragrunt. This should include a description of:

• The problem you are trying to solve.
• The reason why Terraform can’t solve this problem, or data points that suggest there is a long enough time horizon for implementation that it makes sense to workaround it in Terragrunt.
• Use cases for the problem. Why is it important that we have this feature?

Proposed solution

This section should describe which solution you are ultimately picking for implementation. This should describe in detail how this solution addresses the problem. Additionally, this section should include implementation details. Be sure to include code samples so that it is clear how users are intended to use the solution you are proposing!

Note: This section can be left blank in the initial PR, if you are unsure what the best solution is. In this case, include all the possible solutions you can think of as a part of the Alternatives section below. You can fill this section out once you feel confident in a potential approach after discussion on the PR.

Alternatives

This section should describe various options for resolving the problem stated in the Background section. Be sure to include various alternatives here and not just the one you are ultimately proposing. This helps communicate what tradeoffs you are making in picking your solution. Any reasonably complex problem that requires an RFC have multiple solutions that appear to be valid, so it helps to be explicit about why certain solutions were not chosen.

References

This section should include any links that are helpful for background reading such as:

• Relevant issues
• Links to PRs: at a minimum, the initial PR for the RFC, and the implementation PR.
• Links to Terragrunt releases, if the proposed solution has been implemented.
