Required field. ID of the cluster to update a subcluster in.

To get a cluster ID, make a ClusterService.List request.

subcluster_id

string

Required field. ID of the subcluster to update.

To get a subcluster ID, make a SubclusterService.List request.

google.protobuf.FieldMask

Field mask that specifies which attributes of the subcluster should be updated.

resources

Resources

New configuration of resources that should be allocated for each host in the subcluster.

name

string

New name for the subcluster. The name must be unique within the cluster.

int64

Required field. New number of hosts in the subcluster.

decommission_timeout

int64

Timeout to gracefully decommission nodes. In seconds. Default value: 0

autoscaling_config

Configuration for instance group based subclusters

Resources

Field

Description

resource_preset_id

string

ID of the resource preset for computational resources available to a host (CPU, memory etc.).
All available presets are listed in the documentation.

disk_type_id

string

Type of the storage environment for the host.
Possible values:

  • network-hdd - network HDD drive,
  • network-ssd - network SSD drive.

AutoscalingConfig

Field

Description

max_hosts_count

int64

Upper limit for total instance subcluster count.

preemptible

bool

Preemptible instances are stopped at least once every 24 hours, and can be stopped at any time
if their resources are needed by Compute.
For more information, see Preemptible Virtual Machines.

measurement_duration

google.protobuf.Duration

Required field. Time in seconds allotted for averaging metrics.

warmup_duration

google.protobuf.Duration

The warmup time of the instance in seconds. During this time,
traffic is sent to the instance, but instance metrics are not collected.

stabilization_duration

google.protobuf.Duration

Minimum amount of time in seconds allotted for monitoring before
Instance Groups can reduce the number of instances in the group.
During this time, the group size doesn't decrease, even if the new metric values
indicate that it should.

cpu_utilization_target

double

Defines an autoscaling rule based on the average CPU utilization of the instance group.

decommission_timeout

int64

Timeout to gracefully decommission nodes during downscaling. In seconds. Default value: 120

}

An Operation resource. For more information, see Operation.

Field

Description

id

string

ID of the operation.

description

string

Description of the operation. 0-256 characters long.

created_at

google.protobuf.Timestamp

Creation timestamp.

created_by

string

ID of the user or service account who initiated the operation.

modified_at

google.protobuf.Timestamp

The time when the Operation resource was last modified.

done

bool

If the value is false, it means the operation is still in progress.
If true, the operation is completed, and either error or response is available.

metadata

UpdateSubclusterMetadata

Service-specific metadata associated with the operation.
It typically contains the ID of the target resource that the operation is performed on.
Any method that returns a long-running operation should document the metadata type, if any.

error

google.rpc.Status

The error result of the operation in case of failure or cancellation.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.

response

Subcluster

The normal response of the operation in case of success.
If the original method returns no data on success, such as Delete,
the response is google.protobuf.Empty.
If the original method is the standard Create/Update,
the response should be the target resource of the operation.
Any method that returns a long-running operation should document the response type, if any.

Includes only one of the fields error, response.

The operation result.
If done == false and there was no failure detected, neither error nor response is set.
If done == false and there was a failure detected, error is set.
If done == true, exactly one of error or response is set.
