03/09/2023, 12:09 PMHey - we’re just getting started with Infrascost today, and have a question about the previous cost. Is there a way to dry-run the terraform code, so the tool knows what we have deployed already with terraform?

03/09/2023, 12:13 PMHey @aloof-memory-96366, there’s a number of ways to achieve this, can I ask what your setup is:
1. How are you using Infracost?
2. How do you normally deploy your Terraform code? Does your main branch represent what is deployed
3. What is your VCS system

03/09/2023, 12:14 PMUsing the cloud version, with github. The main branch does have what is deployed (split out into projects per environment)

03/09/2023, 12:16 PMok so a follow up question: have you opened a PR yet with the GH app enabled, or have you just run on the main branch?

03/09/2023, 12:17 PMyeah, I have done a PR (to add a new instance group to a GRP project)

03/09/2023, 12:20 PMok great, so going back to your original question. I think I might be a bit confused. What would you like to achieve. As if i understand correctly - your main branch has the current deployed infrastructure, so opening a PR to it will show the previous cost of the “deployed” infrastructure. Am I missing something?

03/09/2023, 12:20 PMThe previous cost of that project is about $150,000 a month

03/09/2023, 12:20 PMright - so this suggests that you have some configuration issues
most likely Infracost is assuming an incorrect project structure

03/09/2023, 12:21 PMhave you added a config file yet?
