What is the process for exposing state in submodules in the root module so that the ‘output’ command will work with Terraform 0.12
I’m trying to migrate our infrastructure to use terraform 0.12 and am seeing an issue that I’m not sure of the proper way to resolve.
I have a nested module structure:
root root/usw2 root/usw2/eks root/usw2/rds
I used to use the following commands to access the submodules output:
terraform output -module=usw2.eks kubeconfig terraform output -module=usw2.rds dburl
When I run those commands now I see the following:
Error: Unsupported option The -module option is no longer supported since Terraform 0.12, because now only root outputs are persisted in the state.
What is the method for exposing the outputs of submodules in the root state? I did not see this documented in https://www.terraform.io/upgrade-guides/0-12.html documentation.
Many thanks in advance!
