Returns the specified zonal instance group. instanceGroups.get a list of available zonal instance groups by making a list() request.
For managed instance groups, use the instanceGroupManagers or regionInstanceGroupManagers methods instead.
HTTP requestGET https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/instanceGroups/{instanceGroup}
The URL uses gRPC Transcoding syntax.
Path parameters Parametersproject
string
Project ID for this request.
zone
string
The name of the zone where the instance group is located.
instanceGroup
string
The name of the instance group.
Authorization requires the following IAM permission on the specified resource instanceGroup:
compute.instanceGroups.getThe request body must be empty.
Response bodyRepresents an Instance Group resource.
Instance Groups can be used to configure a target for load balancing.
Instance groups can either be managed or unmanaged.
To create managed instance groups, use the instanceGroupManager or regionInstanceGroupManager resource instead.
Use zonal unmanaged instance groups if you need to apply load balancing to groups of heterogeneous instances or if you need to manage the instances yourself. You cannot create regional unmanaged instance groups.
For more information, read Instance groups.
If successful, the response body contains data with the following structure:
JSON representation{
"kind": string,
"id": string,
"creationTimestamp": string,
"name": string,
"description": string,
"namedPorts": [
{
"name": string,
"port": integer
}
],
"network": string,
"fingerprint": string,
"zone": string,
"selfLink": string,
"size": integer,
"region": string,
"subnetwork": string
} Fields kind
string
[Output Only] The resource type, which is always compute#instanceGroup for instance groups.
id
string (uint64 format)
[Output Only] A unique identifier for this instance group, generated by the server.
creationTimestamp
string
[Output Only] The creation timestamp for this instance group in RFC3339 text format.
name
string
The name of the instance group. The name must be 1-63 characters long, and comply with RFC1035.
description
string
An optional description of this resource. Provide this property when you create the resource.
namedPorts[]
object
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.
namedPorts[].name
string
The name for this named port. The name must be 1-63 characters long, and comply with RFC1035.
namedPorts[].port
integer
The port number, which can be a value between 1 and 65535.
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).
fingerprint
string (bytes format)
[Output Only] The fingerprint of the named ports. The system uses this fingerprint to detect conflicts when multiple users change the named ports concurrently.
A base64-encoded string.
zone
string
[Output Only] The URL of the zone where the instance group is located (for zonal resources).
selfLink
string
[Output Only] The URL for this instance group. The server generates this URL.
size
integer
[Output Only] The total number of instances in the instance group.
region
string
[Output Only] The URL of the region where the instance group is located (for regional resources).
subnetwork
string
[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).
