Terraform runner creates params.yml for inputs that it is waiting for

[felixzieger]

Terraform runner supports executing terraform modules with parameters from a params.yml file.

It would be helpful for the runner to create a params.yml in the right place that has a comment detailing the missing parameters as a comment.

Example instances//bindings//params.yml:

# vnet_address_space: 192.168.1.1/27
