Creates instances with per-instance configurations in this managed instance group. Instances are created using the current instance template. The create instances
operation is marked DONE
if the createInstances
request is successful. The underlying actions take additional time. You must separately verify the status of the creating
or actions with the listmanagedinstances method.
POST https://compute.googleapis.com/compute/v1/projects/{project}/zones/{zone}/instanceGroupManagers/{instanceGroupManager}/createInstances
The URL uses gRPC Transcoding syntax.
Path parameters Parametersproject
string
Project ID for this request.
zone
string
The name of the zone where the managed instance group is located. It should conform to RFC1035.
instanceGroupManager
string
The name of the managed instance group. It should conform to RFC1035.
Authorization requires the following IAM permission on the specified resource instanceGroupManager
:
compute.instanceGroupManagers.update
requestId
string
An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.
For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request.
The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000
).
The request body contains data with the following structure:
JSON representation{ "instances": [ { "name": string, "preservedState": { "disks": { string: { "source": string, "mode": enum, "autoDelete": enum }, ... }, "metadata": { string: string, ... }, "internalIPs": { string: { "autoDelete": enum, "ipAddress": { "literal": string, "address": string } }, ... }, "externalIPs": { string: { "autoDelete": enum, "ipAddress": { "literal": string, "address": string } }, ... } }, "status": enum, "fingerprint": string } ] }Fields
instances[].name
string
The name of a per-instance configuration and its corresponding instance. Serves as a merge key during instanceGroupManagers.updatePerInstanceConfigs
operations, that is, if a per-instance configuration with the same name exists then it will be updated, otherwise a new one will be created for the VM instance with the same name. An attempt to create a per-instance configuration for a VM instance that either doesn't exist or is not part of the group will result in an error.
instances[].preservedState.disks[]
map (key: string, value: object)

string
The URL of the disk resource that is stateful and should be attached to the VM instance.
instances[].preservedState.disks[].mode
enum
The mode in which to attach this disk, either READ_WRITE
or READ_ONLY
. If not specified, the default is to attach the disk in READ_WRITE
mode.
instances[].preservedState.disks[].autoDelete
enum
These stateful disks will never be deleted during autohealing, update, instance recreate operations. This flag is used to configure if the disk should be deleted after it is no longer used by the group, e.g. when the given instance or the whole MIG is deleted. Note: disks attached in READ_ONLY
mode cannot be auto-deleted.
instances[].preservedState.metadata
map (key: string, value: string)

instances[].preservedState.internalIPs[]
map (key: string, value: object)
Preserved internal IPs defined for this instance. This map is keyed with the name of the network interface.
instances[].preservedState.internalIPs[].autoDelete
enum
These stateful IPs will never be released during autohealing, update or VM instance recreate operations. This flag is used to configure if the IP reservation should be deleted after it is no longer used by the group, e.g. when the given instance or the whole group is deleted.
instances[].preservedState.internalIPs[].ipAddress
object
Ip address representation
instances[].preservedState.internalIPs[].ipAddress.literal
string
An IPv4 internal network address to assign to the instance for this network interface.

instances[].preservedState.externalIPs[]
map (key: string, value: object)
Preserved external IPs defined for this instance. This map is keyed with the name of the network interface.
instances[].preservedState.externalIPs[].autoDelete
enum

instances[].preservedState.externalIPs[].ipAddress
object
Ip address representation
instances[].preservedState.externalIPs[].ipAddress.literal
string

The URL of the reservation for this IP address.
instances[].status
enum
The status of applying this per-instance configuration on the corresponding managed instance.
instances[].fingerprint
string (bytes format)
Fingerprint of this per-instance config. This field can be used in optimistic locking. It is ignored when inserting a per-instance config. An up-to-date fingerprint must be provided in order to update an existing per-instance configuration or the field needs to be unset.
A base64-encoded string.
Response bodyRepresents an Operation resource.
Google Compute Engine has three Operation resources:
You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.
Operations can be global, regional or zonal.
globalOperations
resource.regionOperations
resource.zoneOperations
resource.For more information, read Global, Regional, and Zonal Resources.
Note that completed Operation resources have a limited retention period.
If successful, the response body contains data with the following structure:
