Parameters

Name Description
id
Required
str

Required. The ID can contain any combination of alphanumeric characters including hyphens and underscores, and cannot contain more than 64 characters. The ID is case-preserving and case-insensitive (that is, you may not have two Pool IDs within an Account that differ only by case).
display_name
Required
str

The display name need not be unique and can contain any Unicode characters up to a maximum length of 1024.
vm_size
Required
str

Required. For information about available sizes of virtual machines for Cloud Services Pools (pools created with cloudServiceConfiguration), see Sizes for Cloud Services (https://azure.microsoft.com/documentation/articles/cloud-services-sizes-specs/). Batch supports all Cloud Services VM sizes except ExtraSmall, A1V2 and A2V2. For information about available VM sizes for Pools using Images from the Virtual Machines Marketplace (pools created with virtualMachineConfiguration) see Sizes for Virtual Machines (Linux) (https://azure.microsoft.com/documentation/articles/virtual-machines-linux-sizes/) or Sizes for Virtual Machines (Windows) (https://azure.microsoft.com/documentation/articles/virtual-machines-windows-sizes/). Batch supports all Azure VM sizes except STANDARD_A0 and those with premium storage (STANDARD_GS, STANDARD_DS, and STANDARD_DSV2 series).
cloud_service_configuration
Required
CloudServiceConfiguration

The cloud service configuration for the Pool. This property and virtualMachineConfiguration are mutually exclusive and one of the properties must be specified. This property cannot be specified if the Batch Account was created with its poolAllocationMode property set to 'UserSubscription'.
virtual_machine_configuration
Required
VirtualMachineConfiguration

The virtual machine configuration for the Pool. This property and cloudServiceConfiguration are mutually exclusive and one of the properties must be specified.
resize_timeout
Required
<xref:timedelta>

This timeout applies only to manual scaling; it has no effect when enableAutoScale is set to true. The default value is 15 minutes. The minimum value is 5 minutes. If you specify a value less than 5 minutes, the Batch service returns an error; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request).
target_dedicated_nodes
Required
int

The desired number of dedicated Compute Nodes in the Pool. This property must not be specified if enableAutoScale is set to true. If enableAutoScale is set to false, then you must set either targetDedicatedNodes, targetLowPriorityNodes, or both.
target_low_priority_nodes
Required
int

The desired number of Spot/Low-priority Compute Nodes in the Pool. This property must not be specified if enableAutoScale is set to true. If enableAutoScale is set to false, then you must set either targetDedicatedNodes, targetLowPriorityNodes, or both.
enable_auto_scale
Required
bool

Whether the Pool size should automatically adjust over time. If false, at least one of targetDedicatedNodes and targetLowPriorityNodes must be specified. If true, the autoScaleFormula property is required and the Pool automatically resizes according to the formula. The default value is false.
auto_scale_formula
Required
str

This property must not be specified if enableAutoScale is set to false. It is required if enableAutoScale is set to true. The formula is checked for validity before the Pool is created. If the formula is not valid, the Batch service rejects the request with detailed error information. For more information about specifying this formula, see 'Automatically scale Compute Nodes in an Azure Batch Pool' (https://azure.microsoft.com/documentation/articles/batch-automatic-scaling/).
auto_scale_evaluation_interval
Required
<xref:timedelta>

The default value is 15 minutes. The minimum and maximum value are 5 minutes and 168 hours respectively. If you specify a value less than 5 minutes or greater than 168 hours, the Batch service returns an error; if you are calling the REST API directly, the HTTP status code is 400 (Bad Request).
enable_inter_node_communication
Required
bool

Whether the Pool permits direct communication between Compute Nodes. Enabling inter-node communication limits the maximum size of the Pool due to deployment restrictions on the Compute Nodes of the Pool. This may result in the Pool not reaching its desired size. The default value is false.
network_configuration
Required
NetworkConfiguration

The network configuration for the Pool.
start_task
Required
StartTask

A Task specified to run on each Compute Node as it joins the Pool. The Task runs when the Compute Node is added to the Pool or when the Compute Node is restarted.
certificate_references
Required
list[CertificateReference]

For Windows Nodes, the Batch service installs the Certificates to the specified Certificate store and location. For Linux Compute Nodes, the Certificates are stored in a directory inside the Task working directory and an environment variable AZ_BATCH_CERTIFICATES_DIR is supplied to the Task to query for this location. For Certificates with visibility of 'remoteUser', a 'certs' directory is created in the user's home directory (e.g., /home/{user-name}/certs) and Certificates are placed in that directory. Warning: This property is deprecated and will be removed after February, 2024. Please use the Azure KeyVault Extension instead.
application_package_references
Required
list[ApplicationPackageReference]

When creating a pool, the package's application ID must be fully qualified (/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Batch/batchAccounts/{accountName}/applications/{applicationName}). Changes to Package references affect all new Nodes joining the Pool, but do not affect Compute Nodes that are already in the Pool until they are rebooted or reimaged. There is a maximum of 10 Package references on any given Pool.
application_licenses
Required
list[str]

The list of application licenses must be a subset of available Batch service application licenses. If a license is requested which is not supported, Pool creation will fail.
task_slots_per_node
Required
int

The number of task slots that can be used to run concurrent tasks on a single compute node in the pool. The default value is 1. The maximum value is the smaller of 4 times the number of cores of the vmSize of the pool or 256.
task_scheduling_policy
Required
TaskSchedulingPolicy

How Tasks are distributed across Compute Nodes in a Pool. If not specified, the default is spread.
user_accounts
Required
list[UserAccount]
metadata
Required
list[MetadataItem]

The Batch service does not assign any meaning to metadata; it is solely for the use of user code.
mount_configuration
Required
list[MountConfiguration]

Mount the storage using Azure fileshare, NFS, CIFS or Blobfuse based file system.
target_node_communication_mode
Required
str or NodeCommunicationMode

The desired node communication mode for the pool. If omitted, the default value is Default. Possible values include: 'default', 'classic', 'simplified'
upgrade_policy
Required
UpgradePolicy

The upgrade policy for the Pool. Describes an upgrade policy - automatic, manual, or rolling.
resource_tags
Required
dict[str, str]

The user-defined tags to be associated with the Azure Batch Pool. When specified, these tags are propagated to the backing Azure resources associated with the pool. This property can only be specified when the Batch account was created with the poolAllocationMode property set to 'UserSubscription'.

Methods

as_dict

Return a dict that can be JSONify using json.dump.

Advanced usage might optionally use a callback as parameter:

Key is the attribute name used in Python. Attr_desc is a dict of metadata. Currently contains 'type' with the msrest type and 'key' with the RestAPI encoded key. Value is the current value in this object.

The string returned will be used to serialize the key. If the return type is a list, this is considered hierarchical result dict.

See the three examples in this file:

  • attribute_transformer

  • full_restapi_key_transformer

  • last_restapi_key_transformer

If you want XML serialization, you can pass the kwargs is_xml=True.
deserialize

Parse a str using the RestAPI syntax and return a model.
enable_additional_properties_sending
from_dict

Parse a dict using given key extractor return a model.

By default consider key extractors (rest_key_case_insensitive_extractor, attribute_key_case_insensitive_extractor and last_rest_key_case_insensitive_extractor)
is_xml_model
serialize

Return the JSON that would be sent to azure from this model.

This is an alias to as_dict(full_restapi_key_transformer, keep_readonly=False).

If you want XML serialization, you can pass the kwargs is_xml=True.
validate

Validate this model recursively and return a list of ValidationError.
