Type	Resource
Id	google.compute.instance_groups

Fields

The following fields are returned by SELECT queries:

get

Name	Datatype	Description
id	string (uint64)	Output only. [Output Only] A unique identifier for this instance group, generated by the server.
name	string	The name of the instance group. The name must be 1-63 characters long, and comply withRFC1035. (pattern: [a-z](?:[-a-z0-9]{0,61}[a-z0-9])?)
creationTimestamp	string	Output only. [Output Only] The creation timestamp for this instance group inRFC3339 text format.
description	string	An optional description of this resource. Provide this property when you create the resource.
fingerprint	string (byte)	Output only. [Output Only] The fingerprint of the named ports. The system uses this fingerprint to detect conflicts when multiple users change the named ports concurrently.
kind	string	Output only. [Output Only] The resource type, which is alwayscompute#instanceGroup for instance groups. (default: compute#instanceGroup)
namedPorts	array	Optional. Assigns a name to a port number. For example:{name: "http", port: 80} This allows the system to reference ports by the assigned name instead of a port number. Named ports can also contain multiple ports. For example:[{name: "app1", port: 8080}, {name: "app1", port: 8081}, {name: "app2", port: 8082}] Named ports apply to all instances in this instance group.
network	string	[Output Only] The URL of the network to which all instances in the instance group belong. If your instance has multiple network interfaces, then the network and subnetwork fields only refer to the network and subnet used by your primary interface (nic0).
region	string	Output only. [Output Only] The URL of theregion where the instance group is located (for regional resources).
selfLink	string	Output only. [Output Only] The URL for this instance group. The server generates this URL.
size	integer (int32)	Output only. [Output Only] The total number of instances in the instance group.
subnetwork	string	Output only. [Output Only] The URL of the subnetwork to which all instances in the instance group belong. If your instance has multiple network interfaces, then the network and subnetwork fields only refer to the network and subnet used by your primary interface (nic0).
zone	string	Output only. [Output Only] The URL of thezone where the instance group is located (for zonal resources).

list

Name	Datatype	Description
id	string	Output only. [Output Only] Unique identifier for the resource; defined by the server.
items	array	A list of InstanceGroup resources.
kind	string	Output only. The resource type. (default: compute#regionInstanceGroupList)
nextPageToken	string	Output only. [Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger thanmaxResults, use the nextPageToken as a value for the query parameter pageToken in the next list request. Subsequent list requests will have their own nextPageToken to continue paging through the results.
selfLink	string	Output only. [Output Only] Server-defined URL for this resource.
warning	object	Output only. [Output Only] Informational warning message.
