Property name Value Description Notes
creationTimestamp string [Output Only] The creation timestamp for this instance group in RFC3339 text format.
description string An optional description of this resource. Provide this property when you create the resource.
fingerprint bytes [Output Only] The fingerprint of the named ports. The system uses this fingerprint to detect conflicts when multiple users change the named ports concurrently.
id unsigned long [Output Only] A unique identifier for this instance group, generated by the server.
kind string [Output Only] The resource type, which is always compute#instanceGroup for instance groups.
name string The name of the instance group. The name must be 1-63 characters long, and comply with RFC1035.
namedPorts[] list

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: "http", port: 80},{name: "http", port: 8080}]

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 The URL of the network to which all instances in the instance group belong.
region string The URL of the region where the instance group is located (for regional resources).
size integer [Output Only] The total number of instances in the instance group.
subnetwork string The URL of the subnetwork to which all instances in the instance group belong.
zone string [Output Only] The URL of the zone where the instance group is located (for zonal resources).


Returns the specified instance group resource.
Retrieves the list of instance group resources contained within the specified region.
Lists the instances in the specified instance group and displays information about the named ports. Depending on the specified options, this method can list all instances or only the instances that are running.
Sets the named ports for the specified regional instance group.
Returns permissions that a caller has on the specified resource.
