+  Retrieve Network Endpoint Group's details.

+
+# google\_compute\_network\_endpoint\_group
+
+Use this data source to access a Network Endpoint Group's attributes.
+
+The NEG may be found by providing either a `self_link`, or a `name` and a `zone`.
+
+## Example Usage
+
+```hcl
+data "google_compute_network_endpoint_group" "neg1" {
+	name = "k8s1-abcdef01-myns-mysvc-8080-4b6bac43"
+	zone = "us-central1-a"
+}
+
+data "google_compute_network_endpoint_group" "neg2" {
+	self_link = "https://www.googleapis.com/compute/v1/projects/myproject/zones/us-central1-a/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 Endoint Group name.
+    Provide either this or a `self_link`.
+
+* `zone` - (Optional) The Network Endoint Group availability zone.
+
+* `self_link` - (Optional) The Network Endoint Group self\_link.
+
+## Attributes Reference
+
+In addition the arguments listed above, the following attributes are exported:
+
+* `network` - The network to which all network endpoints in the NEG belong.
+* `subnetwork` - subnetwork to which all network endpoints in the NEG belong.
+* `description` - The NEG description.
+* `network_endpoint_type` - Type of network endpoints in this network endpoint group.
+* `default_port` - The NEG default port.
+* `size` - Number of network endpoints in the network endpoint group.
