I missed this call but wanted to drop in and say thanks! We are now starting to push Infracost across all of our Terraform child module and root module repositories (close to 100 repos now) using the multi-project configuration along with GitHub private modules. We are able to use it exactly how I hoped for child modules, we can run Infracost against our kitchen-terraform test fixtures as “example” cost for potential consumers of the child module. Also give module developers quick visibility on what their change might cost. It works perfect in our root modules as well where we have different tfvars for each environment and even global and regional based tfvars and workflows. We can now see cost change across all these environments prior to code review. Seriously cool stuff folks and I appreciate all the hard work !
