Method: nodeGroups.get

Stay organized with collections Save and categorize content based on your preferences.

Returns the specified NodeGroup. nodeGroups.get a list of available NodeGroups by making a list() request. Note: the "nodes" field should not be used. Use nodeGroups.listNodes instead.

HTTP request

GET https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/nodeGroups/{nodeGroup}

The URL uses gRPC Transcoding syntax.

Path parameters Parameters project

string

Project ID for this request.

zone

string

The name of the zone for this request.

nodeGroup

string

Name of the node group to return.

Request body

The request body must be empty.

Response body

Represents a sole-tenant Node Group resource.

A sole-tenant node is a physical server that is dedicated to hosting VM instances only for your specific project. Use sole-tenant nodes to keep your instances physically separated from instances in other projects, or to group your instances together on the same host hardware. For more information, read Sole-tenant nodes.

If successful, the response body contains data with the following structure:

Fields kind

string

[Output Only] The type of the resource. Always compute#nodeGroup for node group.

id

string (uint64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.

creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.

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.

description

string

An optional description of this resource. Provide this property when you create the resource.

nodeTemplate

string

URL of the node template to create the node group from.

zone

string

[Output Only] The name of the zone where the node group resides, such as us-central1-a.

selfLink

string

[Output Only] Server-defined URL for the resource.

status

enum

size

integer

[Output Only] The total number of nodes in the node group.

autoscalingPolicy

object

Specifies how autoscaling should behave.

autoscalingPolicy.mode

enum

The autoscaling mode. Set to one of: ON, OFF, or ONLY_SCALE_OUT. For more information, see Autoscaler modes.

autoscalingPolicy.minNodes

integer

The minimum number of nodes that the group should have.

autoscalingPolicy.maxNodes

integer

The maximum number of nodes that the group should have. Must be set if autoscaling is enabled. Maximum value allowed is 100.

maintenancePolicy

enum

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.

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 locationHint present in the NodeTemplate.

fingerprint

string (bytes format)

A base64-encoded string.

maintenanceWindow

object

maintenanceWindow.startTime

string

Start time of the window. This must be in UTC format that resolves to one of 00:00, 04:00, 08:00, 12:00, 16:00, or 20:00. For example, both 13:00-5 and 08:00 are valid.

maintenanceWindow.maintenanceDuration

object

[Output only] A predetermined duration for the window, automatically chosen to be the smallest possible in the given scenario.

maintenanceWindow.maintenanceDuration.seconds

string (int64 format)

Span of time at a resolution of a second. Must be from 0 to 315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years

maintenanceWindow.maintenanceDuration.nanos

integer

Span of time that's a fraction of a second at nanosecond resolution. Durations less than one second are represented with a 0 seconds field and a positive nanos field. Must be from 0 to 999,999,999 inclusive.

shareSettings.shareType

enum

Type of sharing for this shared-reservation

shareSettings.projectMap[]

map (key: string, value: object)

A map of project id and project config. This is only valid when shareType's value is SPECIFIC_PROJECTS.

shareSettings.projectMap[].projectId

string

The project ID, should be same as the key of this project config in the parent map.

maintenanceInterval

enum

Specifies the frequency of planned maintenance events. The accepted values are: AS_NEEDED and RECURRENT.

Requires one of the following OAuth scopes:

For more information, see the Authentication Overview.

IAM Permissions

In addition to any permissions specified on the fields above, authorization requires one or more of the following IAM permissions:

To find predefined roles that contain those permissions, see Compute Engine IAM Roles.
