This is a second part of Importing existing resources into Terraform - Step by Step, in earlier article I imported resource mentioned in tf file, here in this article I will be importing existing module resources and update tfstate file. Below are the module structure of my resources in the terraform tf file.
After running terraform plan it shows plan is successful and it will create a new resource, but resource already exists in Microsoft Azure Cloud. But when applying the configuration shows the correct problem/error as shown below.
terraform apply --auto-approve
Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:
# module.resorucegroup.azurerm_resource_group.rg will be created
+ resource "azurerm_resource_group" "rg" {
+ id = (known after apply)
+ location = "eastus"
+ name = "vcloud-lab.com"
+ tags = {
+ "orgnization" = "vcloud-lab.com"
+ "owner" = "vjanvi"
}
}
Plan: 1 to add, 0 to change, 0 to destroy.
module.resorucegroup.azurerm_resource_group.rg: Creating...
╷

To resolve this issue I have to grabbed Resource ID of a resource.
Next command will import existing module resource and update tfstate file. In the import command provide module resource address with resource service id. Import is successful.
terraform import module.resorucegroup.azurerm_resource_group.rg /subscriptions/9e22xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/vCloud-lab.com module.resorucegroup.azurerm_resource_group.rg: Importing from ID "/subscriptions/9e22xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/vCloud-lab.com"... module.resorucegroup.azurerm_resource_group.rg: Import prepared!

[id=/subscriptions/9e22xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/vCloud-lab.com] Import successful! The resources that were imported are shown above.

Next I did init again and apply the tf configuration, it did the upgrade in-place successfully.
terraform apply --auto-approve
