Terraform resource with the ID already exists
When Terraform run task executes in azure devops release pipeline I get an error “A resource with the ID already exists”. The resource exists in Azure but why it is complaining about the resource if this already exists. This should ignore this part. Please help what I need to add in my code that will fix this error! Am I just using this bugging terraform tool for deploying azure resource?
resource "azurerm_resource_group" "test_project" { name = "${var.project_name}-${var.environment}-rg" location = "${var.location}" tags = { application = "${var.project_name}" } } -

The error you’re encountering, “A resource with the ID already exists,” typically occurs when Terraform attempts to create a resource that already exists in Azure but is not currently tracked in the Terraform state file. Terraform relies on its state file to keep track of the resources it manages. If a resource exists in Azure but Terraform doesn’t have it in its state, it will try to create it again, leading to this error.
To resolve this issue, you can import the existing resource into your Terraform state. This will tell Terraform that the resource already exists and should be managed as part of the current configuration. You can use the
terraform importcommand to do this. The import command takes two arguments: the Terraform resource address and the Azure resource ID.Here’s how you can import an Azure Resource Group:
terraform import azurerm_resource_group.test_project /subscriptions/{subscription-id}/resourceGroups/{resource-group-name}Replace
{subscription-id}with your Azure subscription ID and{resource-group-name}with the name of your existing resource group.After importing the resource, Terraform will recognize the existing resource group and manage it according to your configuration.
The retrieved documents do not provide a direct solution to your problem, but mentions the use of
terraform importin a similar context for AWS resources, which is applicable to Azure resources as well. The documents focus on handling errors and setting resource data in state for Azure resources , adding new data sources, and various updates and fixes for the Terraform AzureRM provider . However, the principle of importing existing resources to manage them with Terraform is a common practice across different providers and services.
