+
+# google\_compute\_region\_network\_endpoint\_group
+
+Use this data source to access a Region Network Endpoint Group's attributes.
+
+The RNEG may be found by providing either a `self_link`, or a `name` and a `region`.
+
+## Example Usage
+
+```hcl
+data "google_compute_region_network_endpoint_group" "rneg1" {
+  name = "k8s1-abcdef01-myns-mysvc-8080-4b6bac43"
+  region = "us-central1"
+}
+
+data "google_compute_region_network_endpoint_group" "rneg2" {
+  self_link = "https://www.googleapis.com/compute/v1/projects/myproject/regions/us-central1/networkEndpointGroups/k8s1-abcdef01-myns-mysvc-8080-4b6bac43"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `project` - (Optional) The ID of the project to list versions in. If it is not provided, the provider project is used.
+
+* `name` - (Optional) The Network Endpoint Group name. Provide either this or a `self_link`.
+
+* `region` - (Optional) A reference to the region where the Serverless REGs Reside. Provide either this or a `self_link`.
+
+* `self_link` - (Optional) The Network Endpoint Group self\_link.
+
+## Attributes Reference
+
+In addition the arguments listed above, the following attributes are exported:
+* `id` - an identifier for the resource with format projects/{{project}}/regions/{{region}}/networkEndpointGroups/{{name}}
+* `network` - The network to which all network endpoints in the RNEG belong.
+* `subnetwork` - subnetwork to which all network endpoints in the RNEG belong.
+* `description` - The RNEG description.
+* `network_endpoint_type` - Type of network endpoints in this network endpoint group.
+* `psc_target_service` - The target service url used to set up private service connection to a Google API or a PSC Producer Service Attachment.
+* `default_port` - The RNEG default port.
+* `size` - Number of network endpoints in the network endpoint group.
