The name of thezonewhere the instance group is located.
instanceGroup
string
The name of the instance group.
Authorization requires the followingIAMpermission on the specified resourceinstanceGroup:
compute.instanceGroups.get
Request body
The request body must be empty.
Response body
Represents an Instance Group resource.
Instance Groups can be used to configure a target forload balancing.
Instance groups can either be managed or unmanaged.
To createmanaged instance groups, use theinstanceGroupManagerorregionInstanceGroupManagerresource instead.
Use zonal unmanaged instance groups if you need to applyload balancingto groups of heterogeneous instances or if you need to manage the instances yourself. You cannot create regional unmanaged instance groups.
[Output Only] A unique identifier for this instance group, generated by the server.
creationTimestamp
string
[Output Only] The creation timestamp for this instance group inRFC3339text format.
name
string
The name of the instance group. The name must be 1-63 characters long, and comply withRFC1035.
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 withRFC1035.
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).
[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 thezonewhere 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 theregionwhere 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).
