InstanceGroupManagers: insert

Requires authorization

Creates a managed instance group using the information that you specify in the request. After the group is created, it schedules an action to create instances in the group using the specified instance template. This operation is marked as DONE when the group is created even if the instances in the group have not yet been created. You must separately verify the status of the individual instances with the listmanagedinstances method.

A managed instance group can have up to 1000 VM instances per group. Please contact Cloud Support if you need an increase in this limit.

Request

HTTP request

POST https://www.googleapis.com/compute/beta/projects/project/zones/zone/instanceGroupManagers

Parameters

Parameter name Value Description
Path parameters
project string Project ID for this request.
zone string The name of the zone where you want to create the managed instance group.

Authorization

This request requires authorization with at least one of the following scopes (read more about authentication and authorization).

Scope
https://www.googleapis.com/auth/compute
https://www.googleapis.com/auth/cloud-platform

Request body

In the request body, supply an InstanceGroupManagers resource with the following properties:

Property name Value Description Notes
Required Properties
baseInstanceName string The base instance name to use for instances in this group. The value must be 1-58 characters long. Instances are named by appending a hyphen and a random four-character string to the base instance name. The base instance name must comply with RFC1035.
name string The name of the managed instance group. The name must be 1-63 characters long, and comply with RFC1035.
targetSize integer The target number of running instances for this managed instance group. Deleting or abandoning instances reduces this number. Resizing the group changes this number.

If successful, this method returns a response body with the following structure:

Property name Value Description Notes
kind string [Output Only] Type of the resource. Always compute#operation for Operation resources.
id unsigned long [Output Only] The unique identifier for the resource. This identifier is defined by the server.
creationTimestamp string [Deprecated] This field is deprecated.
name string [Output Only] Name of the resource.
zone string [Output Only] The URL of the zone where the operation resides. Only available when performing per-zone operations.
clientOperationId string [Output Only] Reserved for future use.
operationType string [Output Only] The type of operation, such as insert, update, or delete, and so on.
targetId unsigned long [Output Only] The unique target ID, which identifies a specific incarnation of the target resource.
status string [Output Only] The status of the operation, which can be one of the following: PENDING, RUNNING, or DONE.
statusMessage string [Output Only] An optional textual description of the current status of the operation.
user string [Output Only] User who requested the operation, for example: user@example.com.
progress integer [Output Only] An optional progress indicator that ranges from 0 to 100. There is no requirement that this be linear or support any granularity of operations. This should not be used to guess when the operation will be complete. This number should monotonically increase as the operation progresses.
insertTime string [Output Only] The time that this operation was requested. This value is in RFC3339 text format.
startTime string [Output Only] The time that this operation was started by the server. This value is in RFC3339 text format.
endTime string [Output Only] The time that this operation was completed. This value is in RFC3339 text format.
error object [Output Only] If errors are generated during processing of the operation, this field will be populated.
error.errors[] list [Output Only] The array of errors encountered while processing this operation.
error.errors[].code string [Output Only] The error type identifier for this error.
error.errors[].location string [Output Only] Indicates the field in the request that caused the error. This property is optional.
error.errors[].message string [Output Only] An optional, human-readable error message.
warnings[] list [Output Only] If warning messages are generated during processing of the operation, this field will be populated.
warnings[].code string [Output Only] A warning code, if applicable. For example, Compute Engine returns NO_RESULTS_ON_PAGE if there are no results in the response.
warnings[].message string [Output Only] A human-readable description of the warning code.
warnings[].data[] list [Output Only] Metadata about this warning in key: value format. For example:
"data": [ { "key": "scope", "value": "zones/us-east1-d" }
warnings[].data[].key string [Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be scope and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
warnings[].data[].value string [Output Only] A warning data value corresponding to the key.
httpErrorStatusCode integer [Output Only] If the operation fails, this field contains the HTTP error status code that was returned. For example, a 404 means the resource was not found.
httpErrorMessage string [Output Only] If the operation fails, this field contains the HTTP error message that was returned, such as NOT FOUND.
region string [Output Only] The URL of the region where the operation resides. Only available when performing regional operations.
description string [Output Only] A textual description of the operation, which is set when the operation is created.
