GoogleApi.Dataproc.V1.Model.InstanceGroupConfig (google_api_dataproc v0.48.0) View Source

The config settings for Compute Engine resources in an instance group, such as a master or worker group.


  • accelerators (type: list(GoogleApi.Dataproc.V1.Model.AcceleratorConfig.t), default: nil) - Optional. The Compute Engine accelerator configuration for these instances.
  • diskConfig (type: GoogleApi.Dataproc.V1.Model.DiskConfig.t, default: nil) - Optional. Disk option config settings.
  • imageUri (type: String.t, default: nil) - Optional. The Compute Engine image resource used for cluster instances.The URI can represent an image or image family.Image examples:[project_id]/global/images/[image-id] projects/[project_id]/global/images/[image-id] image-idImage family examples. Dataproc will use the most recent image from the family:[project_id]/global/images/family/[custom-image-family-name] projects/[project_id]/global/images/family/[custom-image-family-name]If the URI is unspecified, it will be inferred from SoftwareConfig.image_version or the system default.
  • instanceNames (type: list(String.t), default: nil) - Output only. The list of instance names. Dataproc derives the names from cluster_name, num_instances, and the instance group.
  • instanceReferences (type: list(GoogleApi.Dataproc.V1.Model.InstanceReference.t), default: nil) - Output only. List of references to Compute Engine instances.
  • isPreemptible (type: boolean(), default: nil) - Output only. Specifies that this instance group contains preemptible instances.
  • machineTypeUri (type: String.t, default: nil) - Optional. The Compute Engine machine type used for cluster instances.A full URL, partial URI, or short name are valid. Examples:[project_id]/zones/us-east1-a/machineTypes/n1-standard-2 projects/[project_id]/zones/us-east1-a/machineTypes/n1-standard-2 n1-standard-2Auto Zone Exception: If you are using the Dataproc Auto Zone Placement ( feature, you must use the short name of the machine type resource, for example, n1-standard-2.
  • managedGroupConfig (type: GoogleApi.Dataproc.V1.Model.ManagedGroupConfig.t, default: nil) - Output only. The config for Compute Engine Instance Group Manager that manages this group. This is only used for preemptible instance groups.
  • minCpuPlatform (type: String.t, default: nil) - Optional. Specifies the minimum cpu platform for the Instance Group. See Dataproc -> Minimum CPU Platform (
  • numInstances (type: integer(), default: nil) - Optional. The number of VM instances in the instance group. For HA cluster master_config groups, must be set to 3. For standard cluster master_config groups, must be set to 1.
  • preemptibility (type: String.t, default: nil) - Optional. Specifies the preemptibility of the instance group.The default value for master and worker groups is NON_PREEMPTIBLE. This default cannot be changed.The default value for secondary instances is PREEMPTIBLE.
