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.
createdAt	string (date-time) Creation timestamp. String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
createdBy	string ID of the user or service account who initiated the operation.
modifiedAt	string (date-time) The time when the Operation resource was last modified. String in RFC3339 text format. The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
done	boolean 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	UpdateInstanceGroupMetadata 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	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.

The range of possible values is from `0001-01-01T00:00:00Z` to `9999-12-31T23:59:59.999999999Z`, i.e. from 0 to 9 digits for fractions of a second. To work with values in this field, use the APIs described in the Protocol Buffers reference. In some languages, built-in datetime utilities do not support nanosecond precision (9 digits).
name	string Name of the instance group. The name is unique within the folder.
description	string Description of the instance group.
labels	string Resource labels as `key:value` pairs.

serviceAccountId	string ID of the service account. The service account will be used for all API calls made by the Instance Groups component on behalf of the user (for example, creating instances, adding them to load balancer target group, etc.). For more information, see Service accounts. To get the service account ID, use a yandex.cloud.iam.v1.ServiceAccountService.List request.
status	enum (Status) Status of the instance group. `STATUS_UNSPECIFIED` `STARTING`: Instance group is being started and will become active soon. `ACTIVE`: Instance group is active. 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
deletionProtection	boolean Flag prohibiting deletion of the instance group. Allowed values: - `false`: The instance group can be deleted. - `true`: The instance group cannot be deleted. The default is `false`.
applicationLoadBalancerSpec	ApplicationLoadBalancerSpec Settings for balancing load between instances via Application Load Balancer (OSI model layer 7).
applicationLoadBalancerState	ApplicationLoadBalancerState Status of the Application Load Balancer target group attributed to the instance group. Returned if there is a working load balancer that the target group is connected to.
autoHealingPolicy	AutoHealingPolicy AutoHealingPolicy policy of the instance group.

InstanceTemplate
