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

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

num_instances: i32

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.

instance_names: Vec<String>

Output only. The list of instance names. Dataproc derives the names from cluster_name, num_instances, and the instance group.

instance_references: Vec<InstanceReference>

Output only. List of references to Compute Engine instances.

image_uri: String

Optional. The Compute Engine image resource used for cluster instances.

The URI can represent an image or image family.

Image examples:

• <https://www.googleapis.com/compute/v1/projects/>[project_id]/global/images/[image-id]
• projects/[project_id]/global/images/[image-id]
• image-id

Image family examples. Dataproc will use the most recent image from the family:

• <https://www.googleapis.com/compute/v1/projects/>[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.

machine_type_uri: String

Optional. The Compute Engine machine type used for cluster instances.

A full URL, partial URI, or short name are valid. Examples:

• <https://www.googleapis.com/compute/v1/projects/>[project_id]/zones/[zone]/machineTypes/n1-standard-2
• projects/[project_id]/zones/[zone]/machineTypes/n1-standard-2
• n1-standard-2

Auto 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.

disk_config: Option<DiskConfig>

Optional. Disk option config settings.

is_preemptible: bool

Output only. Specifies that this instance group contains preemptible instances.

preemptibility: Preemptibility

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.

managed_group_config: Option<ManagedGroupConfig>

Output only. The config for Compute Engine Instance Group Manager that manages this group. This is only used for preemptible instance groups.

accelerators: Vec<AcceleratorConfig>

Optional. The Compute Engine accelerator configuration for these instances.

min_cpu_platform: String

Optional. Specifies the minimum cpu platform for the Instance Group. See Dataproc -> Minimum CPU Platform.

min_num_instances: i32

Optional. The minimum number of primary worker instances to create. If min_num_instances is set, cluster creation will succeed if the number of primary workers created is at least equal to the min_num_instances number.

Example: Cluster creation request with num_instances = 5 and min_num_instances = 3:

• If 4 VMs are created and 1 instance fails, the failed VM is deleted. The cluster is resized to 4 instances and placed in a RUNNING state.
• If 2 instances are created and 3 instances fail, the cluster in placed in an ERROR state. The failed VMs are not deleted.

instance_flexibility_policy: Option<InstanceFlexibilityPolicy>

Optional. Instance flexibility Policy allowing a mixture of VM shapes and provisioning models.

startup_config: Option<StartupConfig>

Optional. Configuration to handle the startup of instances during cluster create and update process.
