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	ResumeInstanceGroupProcessMetadata 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	InstanceGroup 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.

In this state the group manages its instances and monitors their health, creating, deleting, stopping, updating and starting instances as needed. To stop the instance group, call yandex.cloud.compute.v1.instancegroup.InstanceGroupService.Stop. To pause the processes in the instance group, i.e. scaling, checking instances' health, auto-healing and updating them, without stopping the instances, call yandex.cloud.compute.v1.instancegroup.InstanceGroupService.PauseProcesses. `STOPPING`: Instance group is being stopped. Group's instances stop receiving traffic from the load balancer (if any) and are then stopped. `STOPPED`: Instance group is stopped. In this state the group cannot be updated and does not react to any changes made to its instances. To start the instance group, call yandex.cloud.compute.v1.instancegroup.InstanceGroupService.Start. `DELETING`: Instance group is being deleted. `PAUSED`: Instance group is paused. In this state all the processes regarding the group management, i.e. scaling, checking instances' health, auto-healing and updating them, are paused. The instances that were running prior to pausing the group, however, may still be running. To resume the processes in the instance group, call yandex.cloud.compute.v1.instancegroup.InstanceGroupService.ResumeProcesses. The group status will change to `ACTIVE`.
variables[]	Variable

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.
initial_size	int64 Target group size.
cpu_utilization_rule	CpuUtilizationRule Defines an autoscaling rule based on the average CPU utilization of the instance group. If more than one rule is specified, e.g. CPU utilization and one or more Monitoring metrics (`custom_rules`), the size of the instance group will be equal to the maximum of sizes calculated according to each metric.
custom_rules[]	CustomRule Defines an autoscaling rule based on a custom metric from Monitoring. If more than one rule is specified, e.g. CPU utilization (`cpu_utilization_rule`) and one or more Monitoring metrics, the size of the instance group will be equal to the maximum of sizes calculated according to each metric.
auto_scale_type	enum AutoScaleType Autoscaling type. `AUTO_SCALE_TYPE_UNSPECIFIED` `ZONAL`: Scale each zone independently. This is the default. `REGIONAL`: Scale group as a whole.

This field affects which label from the custom metric should be used: `zone_id` or `instance_id`. `RULE_TYPE_UNSPECIFIED` `UTILIZATION`: This type means that the metric applies to one instance. First, Instance Groups calculates the average metric value for each instance, then averages the values for instances in one availability zone or in whole group depends on autoscaling type. This type of metric must have the `instance_id` label. `WORKLOAD`: This type means that the metric applies to instances in one availability zone or to whole group depends on autoscaling type. This type of metric must have the `zone_id` label if ZONAL autoscaling type is chosen.
metric_type	enum MetricType Required field. Type of custom metric. This field affects how Instance Groups calculates the average metric value. `METRIC_TYPE_UNSPECIFIED` `GAUGE`: This type is used for metrics that show the metric value at a certain point in time, such as requests per second to the server on an instance. Instance Groups calculates the average metric value for the period specified in the AutoScale.measurement_duration field. `COUNTER`: This type is used for metrics that monotonically increase over time, such as the total number of requests to the server on an instance. Instance Groups calculates the average value increase for the period specified in the AutoScale.measurement_duration field.
metric_name	string Required field. Name of custom metric in Monitoring that should be used for scaling.
labels	object (map<string, string>) Labels of custom metric in Monitoring that should be used for scaling.

DeployPolicy

Field	Description
max_unavailable	int64 The maximum number of running instances that can be taken offline (i.e., stopped or deleted) at the same time during the update process. If `max_expansion` is not specified or set to zero, `max_unavailable` must be set to a non-zero value.
max_deleting	int64 The maximum number of instances that can be deleted at the same time. The value 0 is any number of virtual machines within the allowed values.
max_creating	int64 The maximum number of instances that can be created at the same time. The value 0 is any number of virtual machines within the allowed values.
max_expansion	int64 The maximum number of instances that can be temporarily allocated above the group's target size during the update process. If `max_unavailable` is not specified or set to zero, `max_expansion` must be set to a non-zero value.
startup_duration	google.protobuf.Duration Instance startup duration. Instance will be considered up and running (and start receiving traffic) only after startup_duration has elapsed and all health checks are passed. See yandex.cloud.compute.v1.instancegroup.ManagedInstance.Status for more information.
strategy	enum Strategy Affects the lifecycle of the instance during deployment. `STRATEGY_UNSPECIFIED` `PROACTIVE`: Instance Groups can forcefully stop a running instance. This is the default. `OPPORTUNISTIC`: Instance Groups does not stop a running instance. Instead, it will wait until the instance stops itself or becomes unhealthy.
minimal_action	enum MinimalAction If instance update requires a less disruptive action than `minimal_action`, Instance Groups performs `minimal_action` to execute the update `MINIMAL_ACTION_UNSPECIFIED` `LIVE_UPDATE`: Updating an instance without stopping. This is the default. `RESTART`: Updating an instance with restart: stopping and then starting the instance. `RECREATE`: Re-creating an instance: deleting an instance and creating a new one.
