Type	Resource
Id	google.compute.node_groups

Fields

The following fields are returned by SELECT queries:

get

Successful response

Name	Datatype	Description
id	string (uint64)	[Output Only] The unique identifier for the resource. This identifier is defined by the server.
name	string	The name of the resource, provided by the client when initially creating the resource. The resource name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
autoscalingPolicy	object	Specifies how autoscaling should behave. (id: NodeGroupAutoscalingPolicy)
creationTimestamp	string	[Output Only] Creation timestamp in RFC3339 text format.
description	string	An optional description of this resource. Provide this property when you create the resource.
fingerprint	string (byte)
kind	string	[Output Only] The type of the resource. Always compute#nodeGroup for node group. (default: compute#nodeGroup)
locationHint	string	An opaque location hint used to place the Node close to other resources. This field is for use by internal tools that use the public API. The location hint here on the NodeGroup overrides any location_hint present in the NodeTemplate.
maintenanceInterval	string	Specifies the frequency of planned maintenance events. The accepted values are: AS_NEEDED and RECURRENT.
maintenancePolicy	string	Specifies how to handle instances when a node in the group undergoes maintenance. Set to one of: DEFAULT, RESTART_IN_PLACE, or MIGRATE_WITHIN_NODE_GROUP. The default value is DEFAULT. For more information, see Maintenance policies.
maintenanceWindow	object	Time window specified for daily maintenance operations. GCE's internal maintenance will be performed within this window. (id: NodeGroupMaintenanceWindow)
nodeTemplate	string	URL of the node template to create the node group from.
selfLink	string	[Output Only] Server-defined URL for the resource.
shareSettings	object	Share-settings for the node group (id: ShareSettings)
size	integer (int32)	[Output Only] The total number of nodes in the node group.
status	string
zone	string	[Output Only] The name of the zone where the node group resides, such as us-central1-a.

list

Successful response

Name	Datatype	Description
id	string	[Output Only] Unique identifier for the resource; defined by the server.
items	array	A list of NodeGroup resources.
kind	string	[Output Only] Type of resource.Always compute#nodeGroupList for lists of node groups. (default: compute#nodeGroupList)
nextPageToken	string	[Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than maxResults, 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] Server-defined URL for this resource.
warning	object	[Output Only] Informational warning message.
