InstanceGroupConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)The config settings for Compute Engine resources in an instance group, such as a master or worker group.
Attributes | |
|---|---|
| Name | Description |
num_instances |
int
Optional. The number of VM instances in the instance group. For `HA cluster `__ master_config <#fields.master_config>__ groups, **must be
set to 3**. For standard cluster
master_config <#fields.master_config>__ groups, **must be
set to 1**.
|
instance_names |
Sequence[str]
Output only. The list of instance names. Dataproc derives the names from cluster_name, num_instances, and the
instance group.
|
image_uri |
str
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/beta/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/beta/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 |
str
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/us-east1-a/machineTypes/n1-standard-2
- projects/[project_id]/zones/us-east1-a/machineTypes/n1-standard-2
- n1-standard-2
**Auto Zone Exception**: If you are using the Dataproc `Auto
Zone
Placement |
disk_config |
google.cloud.dataproc_v1.types.DiskConfig
Optional. Disk option config settings. |
is_preemptible |
bool
Output only. Specifies that this instance group contains preemptible instances. |
preemptibility |
google.cloud.dataproc_v1.types.InstanceGroupConfig.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 |
google.cloud.dataproc_v1.types.ManagedGroupConfig
Output only. The config for Compute Engine Instance Group Manager that manages this group. This is only used for preemptible instance groups. |
accelerators |
Sequence[google.cloud.dataproc_v1.types.AcceleratorConfig]
Optional. The Compute Engine accelerator configuration for these instances. |
min_cpu_platform |
str
Optional. Specifies the minimum cpu platform for the Instance Group. See `Dataproc -> Minimum CPU Platform |
Classes
Preemptibility
Preemptibility(value)Controls the use of preemptible instances within the group.
