The current implementation of Terraform import can only import resources into the state. It does not generate a configuration. Because of this, and prior to running terraform import, it is necessary to manually write a resource configuration block for the resource to which the imported object will be mapped.

First, add the resources to the configuration file:

resource "aws_instance" "example" {

# ...instance configuration...

}

Then run the following command:

$ terraform import aws_instance.example i-abcd1234
