Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

Error: Unsupported option

The -module option is no longer supported since Terraform 0.12, because now
only root outputs are persisted in the state.

exit status 1

k8s version is v1.0.0-pre2

I am seeing this issue too with the latest release binary. It seems there is some disconnect between triton-kubernetes and the updated terraform.

I've reached this point as well. Anyone with more go (is this even a go issue) knowledge know how to handle this?

The -module option has been deprecated since terraform 0.12.

To fix this issue we need to remove the -module option from the terraform output execution and make that the output is declared on the terraform module implementation.
