# aws\_network\_interface\_attachment
Attach an Elastic network interface (ENI) resource with EC2 instance.
## Example Usage
```
resource "aws_network_interface_attachment" "test" {
instance_id = "${aws_instance.test.id}"
network_interface_id = "${aws_network_interface.test.id}"
device_index = 0
}
```
## Argument Reference
The following arguments are supported:
* `instance_id` - (Required) Instance ID to attach.
* `network_interface_id` - (Required) ENI ID to attach.
* `device_index` - (Required) Network interface index (int).
## Attributes Reference
The following attributes are exported:
* `instance_id` - Instance ID.
* `network_interface_id` - Network interface ID.
* `attachment_id` - The ENI Attachment ID.
* `status` - The status of the Network Interface Attachment.
