FAQs

The remote state isn't updating, what do I do?

If the CI process appears to be stuck with a stale tf state then run the following command to force a refresh:

terragrunt refresh

If the CI process is still failing after a refresh look for errors about items no longer available in AWS - say something that was deleted manually via the AWS console or CLI. To explicitly delete the stale resource from TF state use the following command below. Note:terragrunt state rm will not delete the resource from AWS it will unlink it from state only.

terragrunt state rm aws_resource_name
