What is the importance of terraform state ?
- Terraform state stores the information of the resources created during last apply
- When we execute terraform apply,
- terraform first refresh state
- calculates the drift
- drift becomes the plan
- which will be applied
- Refer Here for official docs
Importing resources into terraform
- Now lets assume, we have manually created a resource or our state file is deleted in these case we need to reverse engineering
