Reversed Terraform – generate tf from existing resources.

Within day of a typical DevOps engineer it might come a time when you need to do some reverse work from what normally you would expect to do with Terraform. And that is to create TF code for resources that already exist ( for any given reason ).

If you find yourself in that situation check out https://github.com/GoogleCloudPlatform/terraformer. Its a nifty tool which can help you to achieve that goal and save many hours of manual labour.
